Abstract
Packets of various protocols may contain timestamps generated by a single timestamp engine. In one embodiment, packets of two different protocols, which are referred to as Protocols A and B for simplicity, contain timestamps generated by the same Protocol B timestamp engine. In order to cause a Protocol B timestamp engine to produce a timestamp for a Protocol A packet, information can be provided to the Protocol B timestamp engine indicating that the Protocol A packet is a packet of Protocol B. The information can be provided by an internal header appended to the Protocol A packet that effectively misidentifies the Protocol A packet as a Protocol B packet. As a result, the Protocol B timestamp engine generates and inserts a timestamp for the Protocol A packet as if it were a Protocol B packet. The Protocol A packet, now including the timestamp, can be output or further processed.
