Foundry Networks NetIron XMRHighlights
Foundry Networks XMR Router InformationService Providers today face a number of challenges that require a new breed of solutions in order to ensure successful and profitable operation. Today’s Service Providers operate in an environment of fierce competition that continues to drive service pricing down. A smooth introduction of new, reliable, and scalable services poses a challenge to many Service Providers, yet, is crucial to expanding the subscriber base, and improving subscriber retention. Adding to these challenges is an exponential growth trend in Internet traffic that continues to erode network capacities. Ensuring and increasing profitability are key goals for any Service Provider, which presents the additional challenges of controlling Capital Expenditures (CapEx) and Operational Expenditures (OpEx). Foundry’s NetIron XMR Series of routers are architected to effectively address all these hurdles by offering the state-of-the-art in hardware and software design. The NetIron XMR Series comprises the industry’s most powerful, high density IPv4/IPv6/MPLS multi-service routers. The series is based on a superior terabit-scale architecture that includes Foundry’s cutting-edge 5th generation network processors. The NetIron XMR Series offers highly versatile, cost-efficient solutions for Internet routing, Metro core, large scale IP backbones, and IP carrier’s carrier transport, thereby enabling the deployment of scalable, high value, and profitable services. The NetIron XMR Series includes the 4-slot NetIron XMR 4000 (4 RU), 8-slot NetIron XMR 8000 (7 RU), and the 16-slot NetIron XMR 16000 (14 RU). The series offers industry-leading port capacity and density with up to 64 10 Gigabit Ethernet/320 Gigabit Ethernet ports per system, and up to 192 10 Gigabit Ethernet/960 Gigabit Ethernet ports in a standard 7-foot-rack. The NetIron XMR Series is designed from the ground up for high performance and scalability to address the needs of the most demanding ISP, Internet Data Center, metro service provider, and multi-service operator applications. All routers in the series feature wire-speed, low latency, and low jitter routing for IPv4, IPv6, MPLS, and MPLS VPN services, and they support both edge and core service provider deployments. For metropolitan area networks (MANs), the NetIron XMR Series is capable of wire-speed, low latency, and low jitter Layer 2 switching to allow for cost-efficient and seamless integration with Layer 2 MANs or Layer 2 MAN access layers without compromising performance. Designed for high-end routing applications, the NetIron XMR Series features Foundry Direct Routing (FDR) technology for full Forwarding Information Base (FIB) programming in hardware, together with hardware-based wire-speed access control lists (ACLs) and policy-based routing (PBR) for robust, high performance IPv4, IPv6, and Layer 3 VPN routing. Complementary to FDR is a full suite of unicast and multicast routing protocols for both IPv4 and IPv6. Supported IPv4 protocols include RIP, OSPF, IS-IS, BGP4, PIM-DM, PIM-SM, IGMP, BGP-MP for multicast, and MSDP. Supported IPv6 protocols include RIPng, OSPFv3, BGP-MP for IPv6 (BGP4+), PIM-SSM, and MLD. Building on this solid routing architecture, the NetIron XMR routers also provide dual-stack IPv4/IPv6 wire-speed routing to facilitate a seamless migration to IPv6 without sacrificing performance. A comprehensive set of path calculation and signaling capabilities using OSPF-TE, RSVP-TE, CSPF, and LDP allows the creation of both traffic engineered as well as non-traffic engineered infrastructures. Within either infrastructure, the NetIron XMR Series supports IP over MPLS as well as MPLS VPN applications. The NetIron XMR Series supports all three popular MPLS VPN services, Virtual Leased Line (VLL), LDP-Based Virtual Private LAN Service (VPLS), and BGP/MPLS VPN as per RFC 2547bis, on all ports at wire-speed. In addition, the NetIron XMR Series offers Multi-VRF Routing for environments where virtual routing is needed without the complexity of MPLS. Using Multi-VRF Routing, backbone operators can create multiple routing protocol instances that peer with each other in completely virtualized domains while sharing the same physical routers and links. The NetIron XMR Series architecture ensures complete separation of the routing tables, which allows for supporting overlapping IP address spaces. Forwarding plane separation is supported through the use of standard 802.1Q VLAN tags. The NetIron XMR Series is also designed for enabling the evolving multi-service and triple-play infrastructures. Built with an innovative view of Virtual Output Queuing (VOQ) architectures, packet buffering, and packet scheduling, the NetIron XMR routers offer non-blocking packet forwarding and large capabilities for handling severe congestion scenarios. Built on that superior foundation, the NetIron XMR routers deliver a comprehensive suite of QoS mechanisms to enable next-generation architectures. Using the NetIron XMR routers, operators can implement 8 distinct traffic classes of prioritization with true performance guarantees. Operators can implement those performance guarantees through the NetIron XMR by choosing from different packet scheduling schemes and tweaking the associated configurable parameters. In addition, operators can take advantage of Weighted Random Early Discard (WRED), for differentiated packet dropping in case of congestion within a given traffic class, by relying on DSCP Drop Precedence. With security an increasing concern for today’s operators, the NetIron XMR routers offer a powerful set of security mechanisms that allow operators to enhance both infrastructure security and subscriber security. Featuring highly scalable inbound and outbound ACLs, operators can implement security policies for IPv4, IPv6, as well as Layer 2 through the NetIron XMR Series. These policies can be applied permanently or on demand without impacting normal operations. Receive ACLs further harden platform and infrastructure security, allowing operators to implement strict policies for controlling management traffic and control traffic. To counter IP address spoofing, used in many forms of DoS attacks, the NetIron XMR routers offer wire-speed Unicast Reverse Path Forwarding (uRPF) for both edge applications (strict mode), and backbone applications (loose mode). The NetIron XMR’s uRPF is completely hardware driven, and it allows the routers to check the packet’s source IP address against the routing table to ensure that the packet came from a valid (and expected) source network. To enable long-haul transport, the NetIron XMR Series optics support distances of up to 80 km for 10 Gigabit Ethernet and up to 150 km for Gigabit Ethernet. In addition, the NetIron XMR Series allows operators to connect to existing SONET/SDH OC-192/STM-64 infrastructures through 10 Gigabit Ethernet WAN PHY, which allows for cost-efficient transport up to thousands of kilometers away.
