The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) features a radical new approach to Ethernet over dense wavelength-division multiplexing (DWDM) transport and aggregation: a 4-port 10 Gigabit Ethernet XPonder that includes DWDM transmission functions and Layer 2 switching functions (Figure 1).
Figure 1. Cisco 10 Gigabit Ethernet XPonder Card
Metropolitan (metro) transport networks must support numerous service demands, from low-rate DS-1/T1, DS-3/E3, 10/100BASE-T, and OC-3/STM-1 to higher-rate OC-12/STM-4, Gigabit Ethernet, OC-48/STM-16, OC-192/STM-64, and 10 Gigabit Ethernet services. In the recent past, as the broadband data services have been growing to become a major service and Ethernet is becoming a basic protocol, service providers need more and more integration between Ethernet switching and transport to optimize capital investment and minimize operating costs. Industrial trends indicate that DWDM is being used to transport the huge amount of bandwidth that broadband services are consuming. As a consequence, DWDM needs to evolve from being able to purely manage Layer 1 (where optical wavelengths are dispatched across the network) to offer Layer 1 and Layer 2 capabilities aimed at providing wavelength connection on top of VLAN management; quality-of-service (QoS) services; and multicast, broadcast, and unicast services - all this with a reliability comparable to or better than traditional time-division multiplexing (TDM) technology.
The Cisco ONS 15454 10 Gigabit Ethernet XPonder card portfolio includes two options: a 10 Gigabit Ethernet XPonder card and a 10 Gigabit Ethernet enhanced XPonder card. The portfolio provides a complete solution with the base XPonder optimized for Ethernet access applications, whereas the enhanced XPonder card provides additional capabilities for Ethernet aggregation rings.
The Cisco ONS 15454 10 Gigabit Ethernet XPonder is a single-slot Cisco ONS 15454 board providing four 10-Gbps Small Form-Factor Pluggable (XFP)-based 10 Gigabit Ethernet ports, two of which provide G.709 digital-wrapper and Enhanced Forward Error Correction (E-FEC) capabilities. You can also equip these two ports with DWDM XFPs to allow direct interconnection off the XPonder with the DWDM MSTP system. You can equip two client ports with various XFPs: 10BASE-LR (ER or ZR in the planning stage). You can configure the board in two different operating modes:
• Layer 2 switch: In this operating mode the XPonder behaves as a Layer 2 switch, including the G.709 Rapid Resilient Ring Ethernet Protection (GR3) mechanism.
• Multiple 10 Gigabit Ethernet transponders: In this operating mode the XPonder provides a one-to-one mapping between two 10 Gigabit Ethernet ports, enabling equivalent functions of two standard 10 Gigabit Ethernet DWDM transponders. Each of the 10 Gigabit Ethernet ports providing G.709 digital wrapper and E-FEC are equipped with DWDM XFP to directly interface the cards with the DWDM layer.
DWDM XFPs used as line interfaces provide one 10-Gbps, long-reach, ITU-compliant, 100-GHz-spaced optical interface using LC connectors supporting an OUT-2 G.709 digital wrapper and 10 Gigabit Ethernet LAN physical layer (PHY), or 10 Gigabit Ethernet WAN PHY interfaces. There are 40 different card types of DWDM XFP (one per wavelength), enabling support for 40-channel DWDM networks. When operated within the outlined specifications, each card transports the 10 Gigabit Ethernet signal with a maximum bite error rate (BER) of 10E-15.
You can deploy the XPonder cards in the 12 multiservice interface card slots of the Cisco ONS 15454 platform, in systems with or without cross-connect cards. The addition of a cross-connect card enables the platform to support hybrid applications, containing transparent 10-Gbps services as well as aggregation of other services supported by the Cisco ONS 15454 platform. The only required common card is the appropriate timing, communications, and control card.
The XPonder card provides many carrier-class features and advanced capabilities necessary to deliver 10 Gigabit Ethernet Metro Ethernet services, including the protocol transparency, flexible protection mechanisms, broadcast and multicast topology flow-through timing, management, and performance-monitoring capabilities outlined in the following sections.
Enhanced FEC Capability
The critical feature of the 10 Gigabit Ethernet XPonder is the availability to configure the FEC in three modes (the output bit rate depends on this choice):
• 10.3125 Gbps for 10 Gigabit Ethernet LAN PHY
• 11.095 Gbps for 10 Gigabit Ethernet LAN PHY (over-clocking mode)
Error coding performance can be provisioned:
• NO FEC
• FEC: Standard G.975 Reed-Salomon algorithm
• E-FEC: Standard G.975.1 two orthogonally concatenated block codes (BCH) super FEC codes; this FEC scheme contains three parameterizations of the same scheme of two BCH codes; the constructed code is decoded iteratively to achieve the expected performance
The XPonder card provides transparent wavelength services on the Cisco ONS 15454 platform. Digital-wrapper technology (G.709) adds a management wrapper to the service, allowing the XPonder card to transparently forward the payload while enabling derivation of performance metrics to ensure circuit service quality.
The cards are transparent to the embedded payload and do not access the Cisco ONS 15454 platform cross-connect.
Layer 2 Functions
You can configure the XPonder cards as Ethernet Layer 2 switches:
A tagged VLAN mechanism makes it possible to build an Ethernet ring over a DWDM wavelength. The two trunk ports equipped with DWDM XFPs are used as Layer 1 substratum Network-to-Network Interface (NNI) ports for an Ethernet distribution ring built by various clients shared on the different XPonders belonging to that wavelength (Figure 2).
Figure 2. XPonder Layer 2 Physical Scheme
Figure 3. XPonder Layer 2 Logical Scheme
Layer 2 switches support:
• XPonder with MAC address table with up to 16,000 entries
• Enhanced XPonder with MAC address table with up to 32,000 entries1
• Standard 802.1D virtual bridged LANs and VLAN tagging according to the IEEE 802.1Q (up to 4096 VLAN IDs on all ports)
• Standard 801.1ad S-TAG (or outer tag, or QinQ)
• Per-VLAN MAC address enable-disable1
All Layer 2 packet forwarding and multicast replication is performed at wire speed.
The XPonder card provides QoS features such as ingress policing:
– Bandwidth profile based on committed-information-rate (CIR), committed-burst-size (CBS), and excess-burst-size (EBS) parameters
– Only color-blind implementation
Additional QoS functions on Enhanced XPonder include:
• Add of double tag and Add + Translation
• Add SVLAN +Translate combat-vehicle LAN (CVLAN)1
• Per-CVLAN-to-SVLAN ingress class of service (CoS)
QoS: Egress Policing
• One Strict Priority and seven Weighted Round Robin (WRR) queues (weight can go from 0 to 15); tail drop to control congestion; when zero is configured the queue is managed as Strict Priority queue
• Bandwidth limitation per queue (bandwidth can also be configured per port)
• Up to eight queues configurable for each port
Multicast and Video Broadcast
The Cisco ONS 15454 10 Gigabit Ethernet XPonder supports both push and pull models for video broadcast or multicast applications. The SVLAN-based drop-and-continue approach is used for the push model, where all multicast and video broadcast traffic is dropped at each site. With Internet Group Management Protocol Version 2 (IGMPv2)1 capability, the XPonder provides a pull model where a multicast stream or a video channel is pulled on to the network through a join from the end customer. Multicast VLAN registration (MVR)1 further enhances network flexibility for video applications where a multicast VLAN is reserved for the network independent of the VLAN on which the service is delivered on each port. The translation from multicast VLAN to customer VLAN happens at the client port.
Flexible Protection Mechanisms
The XPonder card provides flexible protection capabilities for both client and DWDM line interfaces, enabling support for numerous network configurations required to deliver the various service-level agreements (SLAs) required by the customer application.
For a multiple-transponder configuration, the XPonder card supports:
• Unprotected client and line: No client terminal interface, XPonder card, or DWDM line protection; the client signal is transported over a single unprotected XPonder card; this configuration is suitable for transporting client payloads over a DWDM network that is being protected through a Layer 2 or Layer 3 protocol
• Y-cable client interface: This interface provides XPonder equipment protection without client terminal equipment interface protection; a single client interface is split to two XPonder cards using a Y-protection device.
• For a Layer 2 configuration, the XPonder provides redundancy with no single point of failure in a ring configuration:
– For ring protection, the XPonder provides revolutionary new GR3 Ethernet protection, integrating G.709 messaging with an Ethernet VLAN mechanism when configured as Layer 2 switches, to provide reliability comparable to older TDM systems. A recovery time of 50 ms (including detection time) can be achieved. The protection mechanism uses a mix of Layer 1 and Layer 2 functions, with fault detection and failure propagation performed through the G.709 bytes (failure propagation is performed at the hardware level) while traffic is flooded, for each protected VLAN on all 10 Gigabit Ethernet wavelength-division multiplexing (WDM) rings. One node is identified (through user configuration) as the master node (or port). This node is responsible for opening and closing the Layer 2 VLAN loop in case of failure.
– The XPonder provides client and card redundancy with SONET/SDH-like 1 + 1 card protection in either the same or a different shelf (within the same multishelf management domain)2 with the following protection models:
The active port is enabled while the standby port stays disabled.
Both active and standby ports are enabled; only the active port forwards while the standby port drops all ingress-egress traffic.
– The GR3 protection mechanism is required.
– The Layer 2 XPonder also supports Y-cable bidirectional-like switching where two cards in 1 + 1 protection are connected through a Y-cable to a single client1.
– Link aggregation (LAG) (802.3ad) protection2 is supported. You can use the Link Aggregation Control Protocol (LACP) to provide local point-to-point resiliency between the co-located router or switch and the XPonder. LAG cannot provide the 50-msec switching that 1 + 1 client protection can, but it allows load balancing and increased bandwidth. In addition, the use of 10GE XPE allows a LAN extension scenario, where it is possible to achieve higher bandwidth usage at either 10 Gigabit Ethernet or 10/100/1000 Mbps.
– Resilient Ethernet Protocol:2 Resilient Ethernet Protocol (REP) was introduced to handle the growth of Ethernet Layer 2 topologies and the resulting consequences of large spanning-tree domains, the increased number of Layer 2 switches, and the increased number of subscribers (increased number of VLANs and MAC addresses). The increased size of Ethernet networks increases the complexity of operations and management. Carrier Ethernet requires fast convergence in access and aggregation networks. Release 9.2 introduces REP on the XPonder for fast and predictable Layer 2 convergence.
The Cisco ONS 15454 provides comprehensive management capabilities to support the operations, administration, monitoring, and provisioning (OAM&P) capabilities through the integrated Cisco Transport Controller Craft Interface with support from the Cisco Transport Manager Element Management System (EMS). The XPonder card incorporates provisionable digital-wrapper (G.709) functions, providing per-wavelength performance-management capabilities, especially for services being transported transparently across the network. Without the digital-wrapper functions, a carrier transporting a service transparently would be unable to identify network impairments that may degrade the transported signal and exceed SLA requirements. The generic communications channel (GCC) of the digital wrapper enables a separate communications channel on a per-wavelength basis. This GCC enables the Cisco ONS 15454 to extend its advanced network autodiscovery capabilities to DWDM-based services. The integrated Cisco ONS 15454 Transport Controller Craft Manager and the Cisco Transport Manager EMS give you OAM&P access for the system.
End-to-End Circuit EVC Provisioning1
The Cisco ONS 15454 10 Gigabit Ethernet XPonder card provides service and network provisioning with Cisco Transport Controller. You can provision the XPonder ring and SVLAN-based Ethernet virtual circuits (EVCs) using Cisco Transport Controller. Both point-to-point and multipoint EVC provisioning are supported.
The XPonder card provides QoS provisioning through Cisco Transport Controller. You can define standard system-level QoS profiles and apply them independently on a per-EVC basis.
The XPonder provides remarkable management capabilities for service and QoS provisioning for Carrier Ethernet services.
The XPonder offers the capability to provision a VLAN database. The Cisco ONS 15454 Transport Controller can perform the action to retrieve all the VLANs available in the network. VLAN retrieval allows you to "view" the WDM ring based on the XPonder card and the EVC or VLAN circuit. You can perform retrieval on a per-VLAN basis; it requires the creation of optical channel trail (OCH-Trail) between the XPonder cards. VLAN retrieval results can be:
• Green: Selected VLAN is configured on both ends of the link
• Orange: Selected VLAN is configured only on one end of the link
• Gray: Selected VLAN is not configured on any end of the link
You can provision all SVLAN associated parameters using predefined profiles.
Multicast VLAN Registration2
The MVR feature on the XPonder is used to separate Layer 3 multicast traffic from the SVLANs carrying data on all the client interfaces of the XPonder. Any IGMP snooped packet with a valid Layer 3 multicast address is placed into a user-defined SVLAN dedicated to multicast traffic.
IGMP Snooping is a nonintrusive Layer 3 monitor for Layer 3 multicast traffic received on the client ports of the XPonder. The Layer 3 packets with Class D IPv4 addresses are snooped per SVLAN if MVR and IGMP are provisioned.
The increasing adoption of Carrier Ethernet (CE) in IP Next-Generation Networks (IP NGNs) as an accepted transport mechanism for next-generation Ethernet services, including Ethernet private line (EPL), Ethernet virtual private line (EVPL), Ethernet LAN (E-LAN), and Ethernet virtual private LAN (EV-PLAN) has resulted in the need for service providers to monitor the health of the services, enforce SLAs, and provide SONET/SDH-like OAM functions. Release 9.2 of the Cisco ONS 15454 introduces Ethernet OAM (E-OAM) functions for the XPonder family of cards to complement their Carrier Ethernet transport functions and provide interworking functions for existing access or edge and core Layer 2/3 devices.
The XPonder in Release 9.2 supports the following E-OAM family of protocols as defined in IEEE and ITU-T. The XPonder provides Provider Bridge functions (per port or per VLAN
• IEEE 802.3ah-2005, Clause 57: Ethernet in the First Mile (EFM)
• ITU-T Y.1731: XPonder support for E-OAM functions that are common between IEEE 802.1ag/802.3ah and Y.1731; in addition, Ethernet-Advanced IP Services (E-AIS) and locked signal (LCK) support for link integrity since Release 9.0
The performance-monitoring capabilities of the XPonder card provide support for Ethernet signal transport. Standard performance parameters for transmit and receive signals are based on RFCs 3635, 2358, 2233, and 1757. Each digital-wrapper channel is monitored per ITU-T digital-wrapper requirements (G.709). Optical parameters on the XFP interfaces are supported, including laser bias, transmit optical power, and receiver optical power. Calculation and accumulation of the performance-monitoring data are in 15-minute and 24-hour intervals.
The XPonder card incorporates faceplate-mounted LEDs to provide a quick visual check of the operational status of the card. An orange circle is printed on the faceplate, indicating the shelf slots in which the card can be installed.
The XPonder supports link integrity using Y.1731 Ethernet OAM-AIS message per SVLAN. You can enable or disable squelching on a per-port basis.
Cisco IOS Software-Like CLI1
The XPonder supports a Cisco IOS® Software-like command-line interface (CLI) for management purposes, allowing customers with Cisco IOS Software-based networks to manage the XPonder in a familiar fashion.
The XPonder card adds several new applications to an already flexible Cisco ONS 15454 platform. Cards have been developed to meet many different network applications, from pure DWDM point-to-point to VPN services in a Metro Ethernet environment. The availability of pluggable XFP optics for DWDM increases dramatically the density of 10 Gigabit Ethernet, reducing the port cost at the same time.
The Layer 2 switching configuration addresses applications requiring huge bandwidth and high flexibility:
• Video distribution: Video-hub topology fits perfectly in the XPonder architecture. Two different approaches are supported:
– XPonder-only DWDM ring, where the only Ethernet switching units feeding the DWDM ring are the XPonders: Many Gigabit Ethernet XPonders feed the video-switching-office (VSO) location while the 10 Gigabit Ethernet XPonder feeds the video-headend-office (VHO) location. This topology provides a huge advantage to the capability for supporting GR3 protection.
Figure 4. Video Distribution Using Ethernet XPonders
– IP over DWDM (IPoDWDM) architecture, where a Cisco CRS-1 Carrier Routing System or Cisco Catalyst® 7600 Switch are directly facing a DWDM network through WDM PHY interfaces: The primary advantage is the full integration of optical and IP layers, with a common control plane providing provisioning, performance monitoring, and alarm correlation functions in addition to capital expenditures (CapEx) savings by avoiding the use of DWDM transponders.
Figure 5. IP over DWDM (IPoDWDM) Architecture
• Cost-optimized Ethernet distribution ring for managed services: Flexibility to aggregate Ethernet on a virtual Ethernet ring in place of many point-to-point transponder-based connections dramatically decreases network CapEx investment.
• Metro Ethernet application: Access-independent architecture with Metro Ethernet Forum 9 (MEF9) and MEF14 certification for environment as EVPL and emulated LAN (ELAN) demonstrates full support for Ethernet carrier applications and business services as well as "triple play" with real video, voice, and data services.
• Metro 10 Gigabit Ethernet connectivity: With the addition of 10 Gigabit Ethernet on data terminals, the need for service providers to add a 10 Gigabit Ethernet transport service becomes critical to provide a complete metro service portfolio to their customer bases. The 10 Gigabit Ethernet XPonder card enables service providers to cost-effectively integrate 10 Gigabit Ethernet into their metro service mix over a multiservice network, reducing the need to deploy an overlay metro DWDM platform, and reducing the cost to deploy the service.
The Cisco Advantage
The Cisco ONS 15454 10 Gigabit Ethernet XPonder Card complements and extends the service capabilities of the Cisco ONS 15454 MSTP. The card enables carriers to take advantage of their existing fiber plant and installed base of Cisco ONS 15454 systems while providing a completely new way to transport and manage Ethernet over the same Cisco ONS 15454 platform.
The Cisco ONS 15454 optical transport solution offers significant advantages over traditional network elements offering 10-Gbps interfaces, including:
• Unprecedented service densities: The Cisco ONS 15454 platform supports up to twenty-four 10 Gigabit Ethernet interfaces per shelf. When installed in a typical central-office bay frame, a bay can support up to ninety-six 10 Gigabit Ethernet interfaces. These industry-leading densities are attainable because of the single-slot footprint of the 10 Gigabit Ethernet XPonder interface card.
• Common line cards and chassis: Optical line cards are not dependant on restoration type, reducing sparing costs and technician confusion. Additionally, as networks and customer interface demands evolve, you can easily redeploy optical circuit packs as necessary.
• Single software load: One software load supports all restoration types listed previously, eliminating unnecessary guesswork when ordering. All protection configurations are covered under a single right-to-use software license. After the software is purchased, all features and full functions are available to you.
• Common chassis: A common chassis supporting all optical interface speeds allows the technician to spend time deploying bandwidth and services instead of learning about multiple equipment platforms. Many equipment vendors offer optical line-speed-specific platforms (for example, OC-3/STM-1 or OC-12/STM-4) and categorize platforms by restoration mechanisms (for example, Unidirectional Path Switched Ring/Subnetwork Connection Protection, 2 Fiber-Bidirectional Line Switched Ring/Multiplex Section-Switched Protection Ring, and 4 Fiber- Bidirectional Line Switched Ring), not only causing ordering confusion but also bringing into question whether the inventoried equipment will accommodate the functions required to support the desired application. The line-rate and restoration flexibility of the Cisco ONS 15454 platform makes ordering and deploying simple, fast, and easy.
• Multiservice interface selection: DS-1/E1 through OC-192/STM-64, Ethernet, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet interfaces are all supported, eliminating the "missing interface" found with many vendors' bit-rate-specific product offerings.
The Cisco ONS 15454, the industry's leading metro optical transport platform, delivers supercharged SONET/SDH transport, integrated optical networking, unprecedented multiservice interfaces, and competitive economic benefits.
