Lossless reconfiguration protocol for multi-domain data plane in software-defined networks

Abstract

Software-Defined Networking (SDN) opens the configuring interfaces for the data plane to improve its flexibility[1]. In the data plane, the switches are partitioned into multiple domains. Each domain is dynamically configured by its controller. The domains are physically connected via the border switches. In the control plane, each controller supports multiple services. Each service runs the same control program at multiple controllers in a distributed manner.
