Apparatus, system, and method for increasing bandwidth utilization in encapsulation tunnels

A disclosed method may include (1) identifying a packet that enters a start point of an encapsulation tunnel that spans at least a portion of a network, (2) discovering a maximum transmission unit of the encapsulation tunnel, (3) determining whether a size of the packet satisfies a size threshold that is based at least in part on the maximum transmission unit of the encapsulation tunnel, (4) detecting an encapsulation-triggering event in connection with the packet, and then in response to detecting the encapsulation-triggering event, (5) forwarding the packet via the start point of the encapsulation tunnel toward an end point of the encapsulation tunnel. Various other systems, methods, and computer-readable media are also disclosed.
