METHOD AND SYSTEM FOR DEPLOYING A NEW SERVICE FUNCTION CHAIN (SFC) BASED ON SIMILARITIES WITH PREVIOUSLY DEPLOYED SFCS

摘要

The disclosure relates to a method and system for deploying a new service function chain (SFC) based on similarities with previously deployed SFCs. A service similarity manager framework is proposed to find the exact or partial matching between incoming SFC requests and previously deployed services to accelerate network service provisioning by skipping one or more service provisioning steps while satisfying different constraints. The method comprises receiving a request for the new SFC. The method comprises generating a vector representation for the requested new SFC. The method comprises comparing the vector representation of the requested new SFC with vector representations of previously deployed SFCs. The method comprises identifying a previously deployed SFC similar to the requested new SFC. The method comprises mapping and instantiating a copy of the previously deployed SFC on one or more physical server.
