Mechanism for fault diagnosis and recovery of network service chains
First Claim
1. A computer program product for fault diagnostics and recovery of network service chains, the computer program product comprising a computer readable storage device having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:
- discovering, by a processor, a network graph representative of components of the network service chains;
identifying, by the processor, intersecting ones of the components of the network service chains in the network graph indicative of a commonality therebetween; and
selectively repairing, by the processor, one or more of the components of at least one of the network service chains up to an entirety thereof based on a component repair sequence that maintains service continuity of the network service chains and that is determined and selectively reordered based on the commonality,wherein the network graph comprises a plurality of graphs, each (i) comprising one or more Virtualized Network Functions, and (ii) corresponding to a respective one of the network service chains.

Abstract
A computer-implemented method is provided for fault diagnostics and recovery of network service chains. The method includes discovering, by a processor, a network graph representative of components of the network service chains. The method further includes identifying, by the processor, intersecting ones of the components of the network service chains in the network graph. The method also includes repairing, by the processor, one or more of the components of at least one of the network service chains based on a component repair sequence that maintains service continuity of the network service chains and that is determined based on a commonality.

6. A system for fault diagnostics and recovery of network service chains, comprising:
-
a processor and a memory, configured to; discover a network graph representative of components of the network service chains; identify intersecting ones of the components of the network service chains in the network graph indicative of a commonality therebetween; and selectively repair one or more of the components of at least one of the network service chains up to an entirety thereof based on a component repair sequence that maintains service continuity of the network service chains and that is determined and selectively reordered based on the commonality, wherein the network graph comprises a plurality of graphs, each (i) comprising one or more Virtualized Network Functions, and (ii) corresponding to a respective one of the network service chains.
