CISCO-WAN-ATM-PREF-ROUTE-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

       DESCRIPTION
           "This MIB facilitates the maintenance of preferred routes
            configuration."  

       REVISION            "200206250000Z"
       DESCRIPTION 
           "Initial version of the preferred routes MIB. 

           Preferred Route allows the user an improved control over
           the Soft Permanent Virtual Circuit (SPVC) or Soft Permanent
           Virtual Path (SPVP) connections. The use of network
           resources by these connections can be explicitly specified
           through the exact lowest-level nodes and the associated
           links the connection has to traverse.

           In subsequent discussion, the term SPVC implicitly applies
           also to SPVP.

           Preferred route is specified only at originating node.

           When an originating node selects a connection to be
           rerouted, the node searches for a route. If a preferred
           route is configured for the connection, the originating
           node uses the configured route as the basis of routing.

           Terminologies used:
           Network Element (NE):
                  The pair of a node identifier and the egress port
                  Identifier associated to the node.

           Master node of a connection: 
                  It is the node which owns the connection and is
                  responsible to establish a data path from its end to
                  the remote end.

           Route Identifier:
                  It is a number uniquely identifying a preferred
                  route within the master node.

           A preferred route consists of up to 20 network elements.
           The number of network elements valid within the route is
           specified by the user.

           Contextually, the node at the first network element is the
           originating node; the node at the last network element (as
           specified by the user in the number of valid network
           elements) is the destination node."
