Extended tag networking

A non-transitory computer-readable storage medium storing instructions, which, when executed on a processor, performs an operation for tag networking, the operation comprising:

• determining that one or more network devices in a computer network are configured to handle a tag;
• receiving, at the one or more network devices, a packet of a traffic flow, wherein the packet includes the tag located among data of the packet;
• reading the packet to identify the tag that is located among the data of the packet;
• performing a tag lookup to find logic that is associated with the tag;
• and
• applying the logic to the packet in response to performing the tag lookup, wherein the logic includes instructions for carrying out a service of the network.

A system, comprising:

• a processor;
• and
• a memory storing program code, which, when executed on the processor, performs an operation for tag networking, the operation comprising:
• determining that one or more network devices in a computer network are configured to handle a tag;
• receiving, at the one or more network devices, a packet of a traffic flow, wherein the packet includes the tag located among data of the packet;
• reading the packet to identify the tag that is located among the data of the packet,
• performing a tag lookup to find logic that is associated with the tag, and
