System and method for integrity reconstitution

摘要

A method of communicating data in a network comprises receiving a copy of a message on a first channel via at least one of a first port and a second port, the first port coupled to a first neighbor node and the second port coupled to a first neighbor's neighbor node; and selecting either the copy of the message received via the first port or the copy of the message received via the second port if a copy of the message is received via both the first port and the second port. If a copy of the message is only received via one of the first port or the second port, the received copy of the message is selected. The selected copy of the message is forwarded on the first channel to a second neighbor node via a third port and to a second neighbor's neighbor node via a fourth port; and the integrity of the selected copy of the message is determined based on supplemental integrity data received from another node, wherein the supplemental integrity data is exclusive of a copy of the message communicated on a second channel.

1. A method of communicating data in a network, the method comprising:
receiving a copy of a message on a first channel via at least one of a first port and a second port, the first port coupled to a first neighbor node and the second port coupled to a first neighbor's neighbor node; selecting either the copy of the message received via the first port or the copy of the message received via the second port if a copy of the message is received via both the first port and the second port; if a copy of the message is only received via one of the first port or the second port, selecting the received copy of the message; forwarding the selected copy of the message on the first channel to at least one of a second neighbor node via a third port or a second neighbor's neighbor node via a fourth port; and determining the integrity of the selected copy of the message based on supplemental integrity data received from another node, wherein the supplemental integrity data is exclusive of a copy of the message communicated on a second channel; wherein the supplemental integrity data includes one of:
an acknowledgment received from another node in the network that received the selected copy of the message forwarded on the first channel, the acknowledgment indicating that the selected copy of the message forwarded on the first channel matches a copy of the message communicated via an independent path on the second channel; orfirst path data received from the first neighbor node via the first port and second path data received from the first neighbor's neighbor node via the second port, wherein the first path data identifies at least a portion of a path traveled by the respective copy of the message received via the first port and the second path data identifies at least a portion of a path traveled by the respective copy of the message received via the second port.
