  • Page 18: Functional Overview Of The Vanguard Router Model

    Functional Overview of the Vanguard Router Model Functional Overview of the Vanguard Router Model Introduction Vanguard devices provide interconnection of LANs over WAN using a routing model based on X.25 packet switching technology. Traffic from a LAN port passes internally to a WAN port via a virtual circuit call. Most other bridge and router manufacturers configure WAN links based on physical connections only.

  • Page 19: Ip Forwarder

    IP Forwarder IP Forwarder Introduction The IP Forwarder provides the Routing, Bridge, or Bridge-Routing function in the Vanguard. Note For more information on Bridge-Router functions refer to “Using Bridging Routers to Connect LANs and Networks” section on page 2-31. Virtual Circuits The connection point of the IP forwarder to the LAN port is a virtual circuit called a Defined by Router Router Interface.

  • Page 20: Wan Adapter

    The Vanguard WAN Adapter allows Vanguard LAN software to implement a more efficient layer of routing. An overlay network that the LAN routing functions see is superimposed on top of the actual virtual circuit network and physical network implemented by the Motorola access devices. WAN Adaptor Figure 2-2 shows how the WAN Adapter is used to provide a LAN overlay network.

  • Page 21

    WAN Adapter Flow Control Data passed from the LAN protocol stacks to the WAN Adapter may be queued inside the WAN module. This is due to the relatively low bandwidth of the WAN port(s) compared with a LAN port and to competition for that limited WAN port bandwidth with serial data access ports.

    Trailer • Byte 1: Indicates the protocol type of the LAN forwarder, such as SR, STPE, and IP. The key Protocol IDs are: IP=00, IPX = 07, Motorola Codex SR=64, Motorola Codex STPE=65, and Motorola Codex TB=66. • Byte 2: Indicates other packet-specific information. This byte contains information that is copied from the Control field portion of the Application field of the packet header.
