Abstract: A technique is provided for adaptively performing service function chaining based on network context. The technique includes receiving a request comprising a flexible SFC template (FST) for provisioning an SFC of a plurality of service functions (SFs). A service function path (SFP) is determined responsive to receipt of data packets corresponding to a pre-defined flow to be transmitted over the network. Monitoring of a pre-defined plurality of parameters associated with the SFP and a network context is performed after implementing the SFP. Based on the monitoring of the pre-defined plurality of parameters and SFP modification criteria, a requirement for modifying the SFP is identified. Responsive to the identification, the SFP is modified and the performance of the modified SFP is monitored based on one or more of the plurality of parameters, a network context after modifying the SFP, and a pre-defined plurality of service performance thresholds.

Abstract: The present disclosure relates to a method and system for optimizing usage of network resources in the communication network. In an embodiment, a session is initiated by a user with a plurality of media servers. The usage of the network resources is optimized by a routing server which monitors session characteristics of an on-going session, user characteristics, media server characteristics and network conditions, wherein the on-going session is hosted by a plurality of session handling media servers from the plurality of media servers in the communication network. The routing server further compares the monitored data with corresponding threshold values and identifies at least one media server which violates the pre-defined threshold. The routing server further identifies one or more alternate media servers based on the media server characteristics and transfer the connectivity of one or more users to the one or more alternate media servers without disconnecting the on-going session.
