B IG I RON R X-4, RX-8, RX-16
F oundry Networks’BigIron RX-Series redefines terabit-capacity for routing and switching in the Enterpri and Service Provider environments.F lexibility,resiliency,curity and performance are hallmarks of the design of the BigIron RX-Series family of10 GbE routers.The BigIron RX-Series is designed to meet tomorrow’s mission-critical,high-performance 10 Gigabit Ethernet switching and routing needs today.It is the industry’s first family of true 96 Gig-ready routers to offer wire-speed,non-blocking performance of up to over 3 billion packets per cond per 7-foot T elco rack.Purpo-built for high-speed networks, the BigIron RX-Series offers a full family of chassis with interchangeable I/O modules allowing for graceful scaling, and investment protection.
The unique design allows for full width 96 Gbps modules or two half width modules with 48 Gbps performance each in any slot. Each module supports distributed switching and packet processing as a standard feature.This allows for graceful growth in the network today as well as technology protection for new high performance modules in the future.The efficient design of the BigIron RX-Series supports up to 64 10 GbE and 384 1 GbE ports per system and up to 192 10 GbE and 1,152 1 GbE wire-speed ports per standard 7-foot T elco rack.The BigIron RX-Series router offers a complete and robust t of standards-bad IPv4 and IPv6 routing protocols,including BGP,ISIS,OSPF and RIP designed to scale
with up to four million IPv4 routes in the Router Information Ba on the main CPU and with 1 million unique IPv4 routes in the Forwarding Information Ba loaded into each I/O module for wire speed routing in hardware.Up to 40,000 ACLs may be configured on the BigIron RX-Series chassis allowing for wire-speed filtering,QoS,switching and routing.
The BigIron RX-Series offers a full range of modular router systems.From a compact 2-slot system the BigIron RX-4,to the 4-slot BigIron RX-8 and the 8-slot BigIron RX-16 systems,BigIron allows network designers to standardize on a single product family for distribution,backbone or core routing applications.BigIron RX-Series routers have redundant power supplies,switch fabrics,and management modules.The robust software incorporates hitless failover and upgrade technology for the management modules and switch fabrics. Network integrity is maintained through in-band and out-of-band network management using highly cure communication tools such as SSH or HTTPS and centralized AAA for access control.The combination of T erabit capacity switching with robust scaleable software with a future proof architecture design in the BigIron RX-Series continues F oundry’s leadership position in high performance switching and routing.
