Cisco IGX 8400
Label Switch Router
Standards-based Multiprotocol Label Switching (MPLS) technology is available on the Cisco IGX 8400 Series multiservice switch platform. An entry point to MPLS on a carrier-class platform, the Cisco IGX 8400 expands the reach of the successful BPX 8600 MPLS technology, often used in conjunction with the Cisco IGX.
The Cisco IGX 8400 is ideal for post, telephone, and telegraph (PTT) carriers and alternative providers that deliver Frame Relay and asynchronous transfer mode (ATM) services for midsized or distributed points of presence (POPs), as well as for deployments that require a robust, cost-effective, multiservice solution. The Cisco IGX 8400 brings the scalability advantages of IP + ATM to large enterprises worldwide.
The Cisco IGX can be upgraded with IP functionality with the addition of the IGX-LSC-72 Label Switch Controller Retrofit Kit. With the Label Switch Controller Retrofit Kit, the IGX provides industry-leading ATM broadband service capabilities and integrates Cisco IOS® software to deliver IP services. The addition of an IGX-LSC-72 to an IGX allows scaling of Internet services and enables the user to provision new integrated IP+ATM services such as voice over IP (VoIP), virtual private networks (VPNs), and Web and content hosting services across the ATM backbone.
The label switch controller (LSC), combined with the Cisco IGX 8400 IP+ATM switch, supports scalable integration of IP services over an ATM network. The MPLS LSC enables the Cisco IGX 8400 to:
- Participate in an MPLS network
- Directly peer with IP routers
- Support the IP features in Cisco IOS software
The MPLS LSC supports highly scalable integration of MPLS (IP+ATM) services by using a direct peer relationship between the Cisco IGX 8400 switch and MPLS routers. This direct peer relationship removes the limitation on the number of IP edge routers typical of traditional IP-over- ATM networks, allowing service providers to meet growing demands for IP services. The MPLS LSC also supports direct and rapid implementation of advanced IP services over ATM networks using Cisco IGX 8400 switches.
The MPLS LSC controls the ATM switch by means of the Virtual Switch Interface (VSI), which runs over an ATM link connecting the two devices.
MPLS combines the performance and virtual circuit capabilities of Layer 2 (data link layer) switching with the scalability of Layer 3 (network layer) routing capabilities. This combination enables service providers to deliver solutions for managing growth, providing differentiated services, and leveraging existing networking infrastructures.
The Cisco IGX 8400 Label Switch Router (LSR) architecture provides the flexibility to:
- Run applications over any combination of Layer 2 technologies
- Support any Layer 3 protocol while scaling the network to meet future needs
By deploying the MPLS LSC across service provider networks, large enterprise networks or wide-area networks (WAN), customers can:
- Save money by using existing ATM and routing infrastructures
- Grow revenue using MPLS-enabled services
- Increase productivity through enhanced network scalability and performance
- Reduce costs of network operations through automated provisioning
The MPLS LSC is a LSR that is configured to control the operation of a separate ATM switch. Together, the MPLS LSC and the controlled ATM switch function as a single ATM MPLS router (ATM-LSR).
