Distributed SNMP agent for frame relay switching network
First Claim
1. For use with a digital data communication network, wherein a plurality of channel units are coupled to respective access lines for associated user equipment, and are operative to interface data that has been transported over a shared aggregate data communication link onto respective ones of said access lines for delivery to said associated user equipment, a method of managing the routing of data from said shared aggregate data communication link to said channel units comprising the steps of:
- (a) distributing a network management protocol agent among said plurality of channel units, exclusive of any intermediate proxy device, said network management protocol agent being operative to decode routing information for a specified channel unit within a prescribed data space of a data packet; and
(b) via a management platform coupled to said network, encoding the identification of an individual channel device for whom said data packet is intended in said prescribed data space of said data packet.

Abstract
A simple network management protocol (SNMP) agent is distributed among individual channel units of frame relay switching system, rather than in a proxy device. The SNMP agent is implemented by encoding the identity of an individual channel device for whom a data packet is intended in the community data string portion of an SNMP packet. For a read request, the address of a channel unit is encoded as an augmented community string, such as “public.#”. For a write request, the address is encoded as an augmented community string, such as “private.#”.

8. A data packet routing system for a frame relay switching network comprising:
-
a plurality of frame relay-based channel units coupled to respective access lines for associated user equipment, and being operative to interface data that has been transported over a shared aggregate data communication link onto respective ones of said access lines for delivery to said associated user equipment; and
a network management protocol agent distributed among said plurality of channel units, exclusive of a proxy device intermediate said network and said channel units, and being operative to decode routing information for a specified channel unit within a prescribed data space of a data packet that has been encoded by a management platform coupled to said network. - View Dependent Claims (9, 10, 11, 12, 13, 14)
