Abstract
A first node in a service mesh is configured to perform one or more services on network traffic obtained from an upstream network element via a pre-existing Transmission Control Protocol (TCP) session and provide the network traffic obtained from the upstream network element via the pre-existing TCP session to a downstream network element. The first node determines that the first node should no longer obtain the network traffic from the upstream network element via the pre-existing TCP session. In response, the first node provides state information for the pre-existing TCP session to the downstream network element. The downstream network element is configured to establish a new TCP session having the state information for the pre-existing TCP session with the upstream network element and to obtain further network traffic from the upstream network element via the new TCP session. The first node terminates the pre-existing TCP session.
