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 network traffic at the network node; determining if a frame within the network traffic is a preemptable frame; if the frame is a preemptable frame, determining if the preemptable frame satisfies a selective encapsulation rule, wherein the selective encapsulation rule comprises a frame length; if the preemptable frame is less than or equal to a specified frame length, transmitting the preemptable frame from the network node without altering the preemptable frame; and if the preemptable frame is greater than the specified frame length, encapsulating the preemptable frame by adding data to the preemptable frame and transmitting the encapsulated preemptable frame from the network node, wherein the added data is at least one of a preemption header or a preemption trailer, and wherein application of the selective encapsulation rule reduces the aggregate encapsulation overhead for the network traffic that is preemptable.
