Distributed software-defined network
This application relates to a distributed software-defined network (“DSDN”) for dynamically configuring and managing a wireless communication network. A plurality of DSDN nodes are connected to each other via a plurality of communication paths. Each communication path directly connects two DSDN nodes. Each DSDN node can provide DSDN configurations across diverse and disparate networks by normalizing its data plane network traffic through translation and packet encapsulation. Furthermore, the DSDN node can provide an architecture tolerant of network interruptions and network system fluctuations. For example, in the case of any one of the DSDN node's network interruptions from other DSDN nodes, the DSDN can provide network reconfiguration using network configuration rules stored in a control plane of each DSDN node. Therefore, various embodiments can increase network reliability by the multiple nodes within a software-defined network independently managing its control plane in response to changed network conditions.
