Network operations including protocol processing of a packet updating an operations data field of a different protocol

Abstract:

In one embodiment, network operations are improved by performing updating operations data in an operations data field associated with the header of a particular protocol during the processing of a different protocol. A particular multiple-protocol (MP) packet is received by a particular network node in a network. The particular MP packet includes multiple protocol headers, including a first protocol header associated with a first protocol and a second protocol header associated with a second protocol. Further, the second protocol header associated with a second operations data field. During protocol processing of the first protocol on the particular MP packet, the second operations data field updated with particular operations data. The particular MP packet is sent from the particular network node, with said sent particular MP packet including said updated second operations data field with particular operations data.
