Abstract
A plurality of agents is instantiated on a corresponding plurality of servers that are running concurrent instances of a control plane application. A first agent is selected from the plurality of agents to mediate communication between a client and the concurrent instances of the control plane application running on the plurality of servers. The first agent replicates uplink packets received from the client for transmission to the plurality of agents. A first connection is used to convey the uplink packets. The first agent transmits a single copy of redundant downlink packets received from the plurality of agents to the client via the first connection. In some cases, the first connection is a stateful transmission control protocol (TCP) connection and the first agent replicates the uplink packets received in a single TCP stream. The first agent merges the redundant downlink packets into the single TCP stream.
