    Data Flow Through the T640 Router on page 7 T640 Router Description The T640 Core Router is a complete routing system that provides Gigabit Ethernet, SONET/SDH, and other high-speed interfaces for large networks and network applications, such as those supported by Internet service providers (ISPs).

  • Page 38: T640 Component Redundancy

    T640 Core Router Hardware Guide T640 Component Redundancy The T640 Core Router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components are redundant: Switch Interface Boards (SIBs)—The router has five SIBs. A T640 router that is connected to a TX Matrix platform requires T640-SIBs ;...

  • Page 39: T640 System Architecture Description

    Forwarding operations in the router are performed by the Packet Forwarding Engines, which consist of hardware, including ASICs, designed by Juniper Networks. The T640 Core Router has two main architectural components: Routing Engine—This component provides Layer 3 routing services and network management.

  • Page 40: Figure 2: Control Packet Handling For Routing And Forwarding Table Updates

    T640 Core Router Hardware Guide Processing of routing protocol packets—The Routing Engine handles all packets that concern routing protocols, freeing the Packet Forwarding Engine to handle only packets that represent Internet traffic. Software modularity—Because each software process is devoted to a different function and uses a separate process space, the failure of one process has little or no effect on the others.

  • Page 41: T640 Packet Forwarding Engine Architecture

    Replacing T640 Packet Forwarding Engine Components Data Flow Through the T640 Router To ensure the efficient movement of data through the T640 Core Router, the router is designed so that ASICs on the hardware components handle the forwarding of data.
