Active Stateful PCE high-availability for the control of Flexi-grid Networks with Network Function Virtualization enabled replication
Ramon Casellas, Ricard Vilalta, Ricardo Martínez, Raül Muñoz · Optical Fiber Communication Conference · 2016
We present, implement and validate an architecture for PCE high-availability combining the virtualization of the control function by means of dynamic replicas and the synchronization of their internal state using the PCEP and BGP-LS protocols.
