Communication layer with dynamic multi-session management

In dynamic multi-session management, a communication layer monitors network indicators during sending of application messages over a session established between sender and receiver nodes. Based on the network indicators, the communication layer determines that the session has insufficient bandwidth. In response, at least one session is added between sender and receiver nodes, where a plurality of parallel sessions is established between sender and receiver nodes. The application messages are sent over the plurality of sessions. The communication layer continues to monitor the network indicators, and when the plurality of sessions is determined to have insufficient bandwidth, adds at least one more session between sender and receiver nodes. The communication layer further determines, based on the network indicators, whether the plurality of sessions have excess bandwidth If so, one or more sessions are removed. The communication layer may further provide ordering mechanisms to sequence messages sent over the plurality of sessions.
