NFV together with SDN provides the flexibility for NFs in the way that they are deployed and managed. The flexibility enables dynamical scale in and scale out through migrating in-process flows among NFs. Due to stateful packet processing in NFs, flow migration has to guarantee loss-free and order-preserving for both flow states and packets. Existing frameworks closely coupled state transfer and packets migration, and thus fail to achieve safe and efficient migration with low overhead. This… CONTINUE READING
