The Cisco® Interface Flexibility (I-Flex) design combines shared port adapters (SPAs) and SPA interface processors (SIPs), taking advantage of an extensible design that helps enable service prioritization for voice, video, and data services. Enterprise and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco Systems® routing platforms. The Cisco I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. Cisco I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications for the Cisco 1-Port OC-48c/STM-16 ATM Shared Port Adapter (1-Port OC-48c ATM SPA; refer to Figure 1).

Product Overview

This data sheet details the features of the new modular OC-48c/STM-16 ATM SPA for Cisco 7600 Series routers. The Cisco 1-Port OC-48c/STM-16 ATM SPA, in conjunction with other SPAs implementing various types of network technologies, allows users to flexibly build cost-effective routing solutions that focus on point-of-presence (POP) and service provider core applications targeted for all telcos and Internet service providers (ISPs), for worldwide use. This SPA includes a comprehensive ATM feature set, including per-virtual circuit and per-virtual path traffic shaping; ATM service classes, including constant bit rate (CBR), non-real time variable bit rate (VBR-nrt), real-time variable bit rate (VBR-rt), unspecified bit rate (UBR), Layer 3 QoS, a high-performance segmentation-and-reassembly (SAR) architecture, and support for a large number of ATM virtual connections. All these features are based on industry specifications and standards.

The Cisco 1-Port OC-48c/STM-16 ATM SPA along with other ATM SPAs address the growing demand for improved ATM QoS features, combined with the advanced Layer 3 class-of-service (CoS) capabilities provided by various Cisco routers. Users now can provide robust QoS mechanisms for prioritization of traffic from traditional and high-speed LANs over an ATM network.

The Cisco 1-Port OC-48c/STM-16 ATM SPA can be inserted in the Cisco 7600 platform that supports various services such as:

• IPv4, IPv6, and Multiprotocol Label Switching (MPLS) hardware-assisted forwarding

• Enhanced security features such as extended access control lists (ACLs), Unicast Return Path Forwarding (uRPF), Internet Control Message Protocol (ICMP) rate limiting, and others

• Extensive QoS implementation based on either "classical" QoS (three type-of-service [ToS] bits), Differentiated Services (DiffServ [six differentiated services code point (DSCP) bits]), or MPLS (3 bits Experimental [EXP])

• Enhanced NetFlow, statistics, and billing data to allow service providers to generate different billing profiles for their customers

• MPLS VPN support that allows for Layer 3 VPN deployments and various related applications

The Cisco 1-Port OC-48c/STM-16 ATM SPA uses replaceable Small Form-Factor Pluggable (SFP) optical modules that allow customer flexibility in using different optical interfaces on the same SPA. It is hot-swappable and supports service-transparent online insertion and removal (OIR), allowing removal of the SPA without impacting the interface processor and other SPAs.

Applications

The Cisco ATM SPAs are designed for a wide range of network applications. The specific combination of ATM features and standards makes these SPAs ideal for service provider infrastructures.

Service Provider Infrastructures

The Cisco 1-Port OC-48c/STM-16 ATM SPA can be used in multiple applications, including (Figure 2):

• WAN core links

• Internet peering

Figure 2. ATM Applications

ATM deployment in service provider infrastructures has seen tremendous growth in recent years as well. This growth has been spurred for several reasons:

• ATM provides highly scalable bandwidth within SONET/SDH infrastructures.

• ATM is inherently a multiservice (data, voice, and video) technology.

• ATM is based on international standards.

The Cisco 1-Port OC-48c/STM-16 ATM SPA provides high-performance interconnectivity, metropolitan (metro), and intra-POP applications between service provider POPs for IP transport. This includes interconnecting multiservice edge to ATM core as well as ISP peering points. Through the support of ATM Forum specifications and IETF and ITU standards, the Cisco ATM SPAs can be deployed with any standards-based ATM switch, including the Cisco MGX ® 8800 Series, Cisco MGX 8900 Series, Cisco BPX ® 8600 Series, and Cisco IGX 8400 Series products.

The Cisco ATM SPAs in conjunction with the Cisco SIPs allow service providers to effectively manage the bandwidth at the edges and core of the network while implementing value-added Layer 3 QoS services such as Weighted Random Early Detection (WRED), policing, Low-Latency Queuing (LLQ), and Class-Based Weighted Fair Queuing (CBWFQ).

Key Features and Benefits

The ATM SPAs offer many advantages, including support for the following features:

• The Cisco ATM SPAs support per-virtual circuit and per-virtual path shaping, including industry-leading minimum 1-kbps granularity, allowing flexibility and control over every virtual circuit and virtual path configured.

• IP QoS and Layer 3 QoS features - The Cisco SIPs and ATM SPAs support per-virtual circuit IP QoS features that allow customers to apply advanced-queuing and bandwidth-management functions, including LLQ, WRED, and policing to individual virtual circuits to avoid congestion and delay. In addition, extended ACLs and distributed traffic shaping (dTS) are supported on a per-virtual circuit basis on both ingress and egress.

• IP/MPLS-to-ATM QoS mapping - Also supported is IP-to-ATM QoS matching and setting of cell loss priority (CLP) bit and virtual circuit bundling, which allows customers to divide traffic on different virtual circuits, depending on the desired CoS.
