Migration time experimental evaluation in a Quagga based-software router

We illustrate an experimental test-bed to evaluate the routing plane migration time based on QUAGGA routing software. The operation mode correctness of the OSPF routing protocol is also verified. The realized test-bed allows for an evaluation of the migration time as a function of the number of nodes of an emulated network. We show that even when the network links are loaded with data traffic, the migration time is low and the migration does not degrade the performance of the OSPF routing protocol. For instance the migration time is less than 12 ms in the case of an emulated network of 500 nodes and when the links are 70% loaded. © 2013 IEEE
