Patent Primary Examiner
A method is implemented by a network device to reduce bandwidth and compute resources needed by the controller of a software defined networking (SDN) controller by distributing monitoring of virtual network functions (VNFs) to data plane nodes (DPNs) in a SDN network. The method includes receiving a monitoring request from the SDN controller to monitor a VNF, receiving a byte sequence from the SDN controller for the VNF, and generating flow table entries for monitoring the VNF by matching the byte sequence with monitoring response messages from the VNF.
