store and forward lockup

Store-and-forward lockup is the blocking of sections of a data packet switching network. This situation, also known as direct partial route blocking, belongs to total blocking, deadlocks or deadly embraces.

Deadlocking of partial links can occur in data packet switches that use the store-and-forward method. In this method, data packets are transmitted to the next node via partial links. If a queue forms at the next switching node, the forwarding of the data packets is blocked or delayed. A deadlock can be triggered by a full queue.

Resolving deadlocks is extremely difficult and usually involves data loss. However, there are several procedures that prevent store-and-forward lockups from occurring in the first place.
