TX Matrix Router Description

The Juniper Networks TX Matrix router is the centralized switch fabric of the routing matrix, which is a terabit routing system interconnecting up to four T640 Core Routers to deliver up to 2.56 terabits per second (Tbps) of subscriber switching capacity. The routing matrix multichassis architecture provides scalable growth for aggregation and core services for voice, video, and data networks. It provides a flexible and cost-effective means to simplify large point-of-presence (POP) and central office environments. The routing matrix delivers high-availability services from tunnel services, ATM, DS3, OC3/STM1, OC12/STM4, Gigabit Ethernet, 10-Gigabit Ethernet, OC48/STM16, OC192/STM64, and other high-speed interfaces.

The routing matrix leverages the intelligent virtual services capabilities of Junos OS, which enable you to create multiple application-specific logical networks over a single physical topology. This gives you the ability to virtually separate traffic types that require unique network attributes—such as ATM or high-priority voice over IP (VoIP) and third-generation (3G) mobile traffic—from bulk transit IP traffic.

The TX Matrix router architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the TX Matrix router to achieve terabit performance levels. Control operations in the TX Matrix router are performed by the host subsystem, which runs Junos OS to handle traffic engineering and configuration management. High-availability, interchassis communications are provided by an Ethernet LAN that interconnects the host subsystems in the TX Matrix router and the T640 routers.

The TX Matrix router is a modular, rack-mountable system. One TX Matrix router can be installed in one standard 19-in. wide, 78-in. high, EIA telco rack.
