TX Matrix Plus Router Description
The TX Matrix Plus router is the centralized switch fabric of the routing matrix, which is
a multiterabit routing system for interconnecting T1600 routers. Each T1600 router
connected to the TX Matrix Plus router adds 1.6 terabits per second (Tbps) of nonblocking
subscriber switching capacity to the routing matrix. Currently, the TX Matrix Plus router
supports connections to up to four T1600 routers.
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 router architecture cleanly separates control operations from packet-forwarding
operations. This design eliminates processing and traffic bottlenecks, permitting the
routing matrix to achieve terabit performance levels. Control operations in the routing
matrix 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
Plus router and the T1600 routers.
The TX Matrix Plus router is a modular, rack-mountable system that can be installed in
one standard 23-in. wide, 78-in. high, EIA telco rack.
The routing matrix consists of the following components:
•
One TX Matrix Plus router
•
Up to four T1600 routers
