Abstract
This application describes techniques for replicating data at a primary routing engine of a network device before processing the data at a transport layer of the primary routing engine, wherein the data is to be sent to a routing peer via a routing communication session, and sending the replicated data to a secondary routing engine of the network device to be processed at a transport layer of the secondary routing engine. The secondary routing engine, in response to detecting that a socket buffer for buffering the replicated data has reached a predefined high occupancy threshold, outputs a notification to the primary routing engine. In response to receiving the notification, an application-layer routing process of the primary routing engine refrains from sending at least some of a plurality of routing updates to the routing peer, and continues to send keepalive messages for the routing communication session to the routing peer.
