Transport network multiplexing for transport and ethernet packets

A system for processing a transport packet and an Ethernet packet comprising:

• a transport interface for receiving a transport stream comprising the transport packet, the transport packet formatted in compliance with a first protocol specification;
• a network interface for receiving a network stream comprising the Ethernet packet formatted in compliance with an Ethernet specification, wherein the first protocol specification is different from the Ethernet specification;
• a packet identifier coupled to the transport interface for filtering the transport stream and selecting the transport packet;
• a data formatter coupled to the network interface for encapsulating the Ethernet packet such that the Ethernet packet header information is preserved, the encapsulating including appending a transport header to at least a portion of the Ethernet packet, to form a reformatted packet formatted in compliance with the first protocol specification;
• a multiplexer for receiving the transport packet from the packet identifier, for receiving the reformatted packet from the data formatter, and for selecting one of the transport packet and the reformatted packet for output into an output stream of packets, wherein the output stream of packets is formatted in compliance with the first protocol specification;
• and
• a system controller for controlling the multiplexer to give priority to the transport packet over the reformatted packet.

A program storage device readable by machine, tangibly embodying a program of instructions, which when executed by the machine, cause the machine to perform a method for processing a transport packet and an Ethernet packet, the method comprising:

• receiving at a transport interface a transport stream comprising the transport packet and receiving at a network interface a network stream comprising the Ethernet packet formatted in compliance with an Ethernet specification, the transport packet formatted in compliance with a first protocol specification different from the Ethernet specification;
• filtering the transport stream to select at least the transport packet;
• encapsulating the Ethernet packet such that the Ethernet packet header information is preserved, the encapsulating including appending a transport header to at least a portion of the Ethernet packet to form a reformatted packet formatted in compliance with the first protocol specification;
• and
• selecting one of the transport packet and the reformatted packet for output into an output stream of packets, wherein the output stream of packets is formatted in compliance with the first protocol specification, wherein selecting further comprises giving priority to the transport packet over the reformatted packet.
