Systems and methods are provided for predicting an impending change to Interior Gateway Protocol (IGP) metrics associated with Network Elements (NEs) in an optical network. A method, according to one implementation, includes receiving Performance Monitoring (PM) data related to an optical network having a plurality of links. The method also includes analyzing the PM data to predict the likelihood of an impending change to an IGP metric associated with a problematic link of the plurality of links.

Predicting impending change to interior gateway protocol (IGP) metrics

A caching mechanism is provided for use by a Bid Manager in a multi-agent resource allocation bidding system. The caching mechanism stores the most recent bids issued by one or more Bidders for a given bidding context. The cache is updated using a notification mechanism.

Caching mechanism to optimize a bidding process used to select resources and services

A RIP-based caching mechanism for bids in a distributed automatic route selection system for a network of PBXs. The PBXs are interconnected for propagating bid requests and replies therebetween. A cache table is maintained in each one of the PBXs for storing cached bid values for unused ones of the neighboring PBXs from whom replies have not been received responsive to a bid request. A subscribers table is also maintained in each PBX for identifying additional ones of the PBXs to whom bid value updates must be sent for updating their cache tables.

Distributed automatic route selection using RIP caching

A multi-agent system for selecting a service based on competing bids, comprising a Bid Manager agent for issuing a call for bids, receiving the bids and selecting a best bid from among the received bids taking into consideration Quality of Service, and a plurality of Bidder agents for issuing the bids in response to the call for bids, wherein one of the Bidder agents issues the best bid and provides the service upon selection of the best bid by the Bid Manager.
