The Cisco ML-Series interface cards provide exceptional Ethernet switching capabilities for multiservice provisioning platforms (MSPPs). Cisco has coupled the market-leading optical capabilities of the Cisco ONS 15454 MSPP with proven Cisco IOS ® Software to deliver profitable Carrier Ethernet solutions over a multiservice network architecture.

Product Overview

The Cisco ML-Series cards for the Cisco ONS 15454 MSPP (Figure 1) are industry-leading Ethernet switching modules for integration into a SONET/SDH optical transport platform. The cards extend the multiservice capabilities and flexibility offered by the Cisco ONS 15454 platform.

Figure 1. Cisco ML-Series 10-Port Ethernet Multirate Card for Cisco ONS 15454 MSPP

Through the integration of the industry's most widely deployed and tested Ethernet and IP technology, Cisco IOS Software, with the industry's most successful multiservice provisioning platform, the Cisco ONS 15454, service providers and enterprise customers are provided with a single integrated platform for delivering true carrier-class Metro Ethernet, TDM, and optical transport services and applications.
The Cisco ONS 15454 ML-Series 10-Port Multirate Ethernet Card (ML-MR-10) is the newest addition to the Cisco ML-Series card portfolio, and provides the flexibility to deploy multirate Ethernet services (10,100, 1000 Mbps) over a single card by supporting 10 Small Form-Factor Pluggable (SFP)-based multirate ports.
The Cisco ML-Series single-slot cards can be installed in any of the 12 multiservice interface slots in a Cisco ONS 15454 shelf assembly and can be mixed and matched within the assembly or network to provide flexible architectures to meet the user's application needs. Each card has virtual interfaces that are mapped to SONET/SDH optical interfaces for transport with other services between network elements over 155-Mbps to 10-Gbps optical line rates. Packet transport bandwidth over the chosen optical interface is provisionable, allowing efficient matching and scalability of ingress to transport traffic requirements, based upon oversubscription requirements.
The Cisco ML-MR-10 card supports standard-based IEEE 802.17b Resilient Packet Ring (RPR), which supports increased bandwidth usage over a SONET/SDH ring. 802.17b RPR features also include steering, shortest-path selection, advanced quality of service (QoS), fairness, and spatial reuse for bridging.
In addition to RPR, the Cisco ML-MR-10 card supports 26 Packet over SONET (PoS) ports that enable aggregation of 26 point-to-point Ethernet-over-SONET/SDH circuits.
The advanced set of QoS features on the Cisco ML-MR-10 card allows the network administrator to fine-tune the network and create and support a wide range of SLAs. Table 1 lists some of the features and benefits.
Ethernet Virtual Connection (EVC): The Cisco ML-MR-10 card adopts the Metro Ethernet Forum (MEF) Ethernet Services Framework using EVC Infrastructure/Ethernet Infrastructure (EI). Connectivity between User-Network Interfaces (UNIs) is specified by the Ethernet Virtual Connection (EVC). An EVC represents a conceptual "service pipe" within the service provider network. EVC architecture supported by Cisco IOS Software provides a common framework for service provisioning Carrier Ethernet devices. In Cisco ONS 15454 Software Release 8.5, the Cisco ML-MR-10 card supports Ethernet Virtual Private Line services over an RPR ring.

Table 1. Features and Benefits for QoS

Feature

Benefit

Flexible packet classification

Classifies packets per EVC or per input port based on class of service (CoS), IP Precedence, or IP differentiated services code points (DSCPs), allowing the service provider to tailor packet handling based on the user's traffic.

Policing

Policing per EVC or per input port, allows the service provider to contain a user to the SLA bandwidth requirements, reducing the likelihood that a user will flood the network. Policing is supported on aggregated bandwidth of a link-aggregated group.

Priority marking

Provides a mechanism, when using either .1Q or QinQ features, for a service provider to reclassify (mark) a packet with a wrapper Ethernet 802.1p value, allowing downstream nodes to treat the packet differently and transparently transporting the original CoS bits of the packet across a service provider network.

Per-class queuing

Provides fair access to excess network resources, allows allocation of bandwidth to support SLAs, and helps ensure that applications with high network-resource requirements are adequately serviced.

Scheduling

Adds weighting capabilities to Weighted Deficit Round Robin scheduling to provide fair access to excess bandwidth as well as throughput to each class. Supports strict priority queue for low latency traffic.

The Cisco ML-MR-10 card offers important advantages in service provider network architectures, supporting new, profitable services as well as simplifying service activation. Table 2 outlines some of these capabilities.

Table 2. Features and Benefits for Service Provider Network Architectures

Feature

Benefit

Admission control

During service provisioning, the Cisco ML-MR-10 card verifies that QoS resources have not been accidentally overcommitted.

Network scaling and flexibility

The Cisco ML-MR-10 card supports VLAN-ID translation. This capability allows the service provider to change the ingress VLAN tags (802.1Q or 802.1Q in .1Q) to avoid VLAN collisions within the network (resulting from the use of the same VLAN ID by different customers) and translate them back at the egress of the network.

Network resiliency

Support for IEEE 802.17B RPR over SONET/SDH provides sub-50-ms recovery times for data services, depending on the service offering.

Efficient bandwidth use

The use of RPR technology allows full use of the network bandwidth during normal network operation of a properly designed network.

Reduced interface costs

The use of the Cisco ML-Series cards and shared bandwidth transport allows the service provider to benefit from statistically multiplexing the edge traffic before handing off a more efficiently filled interface to the core router or switch.

Applications

The Cisco ML-MR-10 card provides the flexibility to meet the demands of a wide variety of network applications found within many service providers' transport networks. The following figures show a few of the applications that can be cost-effectively deployed using the Cisco ONS 15454 with the ML-MR-10 cards.

Ethernet Service Delivery

The Cisco ONS 15454 with ML-MR-10 cards can be used for any service delivery based on the type of SFP module plugged into the Ethernet port. The platform supports 10/100/1000 BASE-T, 100BASE-FX/LX/BX, and 1000-BASE SX/LX/ZX. Customers can use the Cisco ML-MR-10 cards to offer a wide range of Ethernet services with Layer 2 switching, RPR, and advanced QoS capabilities.

Figure 2. Ethernet Service Delivery

Interoffice Facility Networks

All traditional local exchange carriers (LEC) have used SONET/SDH technology to interconnect their central offices. With the explosion of data-related services and the growth of termination equipment with integrated Ethernet interfaces and protocols, these carriers increasingly need to transport data traffic more efficiently. Using the Cisco ML-MR-10 cards to interconnect data traffic between the remote terminal equipment and the central core router provides transport bandwidth efficiency by statistically multiplexing and aggregating traffic for efficient router port use, reducing the quantity of core router interfaces. Management benefits are garnered through the integration of data switching into the optical platform, reducing the number of data-communication-network (DCN) ports. Figure 3 shows an interoffice facility (IOF) transport network.

Figure 3. IOF Transport Network 

Metro Data Services Network

A metropolitan network that supports a wide range of service capabilities allows the service provider to offer a tariff mix to meet customer needs. The Cisco ONS 15454 provides the foundation for building an advanced multiservice network over an extremely reliable SONET/SDH infrastructure. The Cisco ML-MR-10 card supports two efficient architectures with RPR rings (refer to Figure 4) and point-to-point port aggregation (see Figure 5). Data services delivery, through EVCs, is supported by the Cisco ML-MR-10 card through the use of 802.1Q in the .1Q VLAN protocol, VLAN translation, input rate limiting, and advanced QoS features, including queue bandwidth control and traffic priority marking. These flexible features allow the service provider to build, control, and guarantee the delivery of the SLAs offered for each service type. To help service provider technicians manage and use the network, the Cisco ML-MR-10 card offers integrated Cisco IOS Software, the industry's best-known Layer 2 and Layer 3 technology, reducing training time and cost.

Cable Television Data Transport

Cable television operators are experiencing rapid growth of subscribers to their data services. The Cisco ONS 15454 with ML-MR-10 cards provides a solution to efficiently transport the increasing data on cable television networks. The Cisco solution allows the cable operator to aggregate data traffic, using the Cisco ML-MR-10 cards, from multiple secondary headends and statistically multiplex it onto shared transport bandwidth for handoff to a core router at the master headend (Figure 5). Cable modem traffic is bursty, and the sharing of bandwidth allows better use of optical transport resources compared to dedicated point-to-point connections. The advanced QoS capabilities of the Cisco ML-MR-10 cards allow the cable network engineer to design the network to support the committed information rate (CIR) necessary for the types of services being offered, such as Web browsing, VoIP, and video on demand (VoD). The Cisco ML-MR-10 cards allow the user to build traffic queues and associate priority and bandwidth with each queue type, to meet the transport demands of each service. The Cisco ONS 15454 platform supports in-service bandwidth upgrades and allows the transport network to scale from 155 Mbps to 320 Gbps using dense wavelength-division multiplexing (DWDM), thereby easily accommodating growth.
