Abstract: Approaches in accordance with various illustrative embodiments provide for the management of active connections in a network environment. In particular, various embodiments implement keep alive functionality in components such as network processing units (NPUs) of network devices such as routers and switches, instead of host processors for those devices. When a status message is received, such as a hello message, the NPU can set or refresh a hit bit in a table entry for a given connection with a peer device. If a subsequent status message is not received within a keep alive interval of the last received status message, then the NPU can determine that the connection with the peer device is stale and can inform the host processor that the connection is no longer available for routing network traffic. The status messages are terminated in the NPU and prevented from being received and processed by the host processor.
