First Claim
Patent Images
1. A method for performing auto-sensing of protocols used for communicating between entities of a data network, the method comprising:
- transmitting, from a first router, a plurality of requests, one for each of a set of LMI protocols, to at least one other network device;
receiving at least one response to at least one of said plurality of requests;
identifying at least one LMI protocol associated with the at least one response; and
automatically configuring the router to utilize said at least one LMI protocol in response to said at least one response.

Abstract
The invention provides a method and system for auto-sensing LMI protocols in frame relay networks. When a router is first coupled to a frame relay network, it automatically configures the local management interface (LMI) to use one of a selected set of possible LMI protocols, by generating a set of protocol requests for a plurality of protocols, and by thereafter simultaneously listening for protocol responses from the configuration server. Multiple valid responses from the configuration server are assigned priority in response to which valid response is last to arrive.
