NETWORK TRAFFIC PREEMPTION USING INTERMITTENT ENCAPSULATION

摘要

An example method for intermittent encapsulation of preemptable network traffic at a network node can include receiving a frame at the network node and determining if the frame is a preemptable frame. A preemptable frame is a frame that can be preempted, suspended, interrupted, etc. after transmission begins in order to transmit a preemptive frame. If the frame is a preemptable frame, the method can include determining if the preemptable frame satisfies a selective encapsulation rule. If the preemptable frame does not satisfy the selective encapsulation rule, the method can include transmitting the preemptable frame from the network node without encapsulation. Alternatively, if the preemptable frame satisfies the selective encapsulation rule, the method can include encapsulating and transmitting the preemptable frame from the network node. The preemptable frame can be encapsulated with a preemption header and/or a preemption trailer.

1. A method for intermittent encapsulation of preemptable network traffic at a network node, comprising:
receiving a frame at the network node; determining if the frame is a preemptable frame; if the frame is a preemptable frame, determining if the preemptable frame satisfies a selective encapsulation rule; if the preemptable frame does not satisfy the selective encapsulation rule, transmitting the preemptable frame from the network node without encapsulating the preemptable frame; and if the preemptable frame satisfies the selective encapsulation rule, encapsulating the preemptable frame and transmitting the encapsulated preemptable frame from the network node, wherein the preemptable frame is encapsulated with at least one of a preemption header and a preemption trailer.
