Working with Flow Identifier Specifications
The various packet connectivity technologies have a variety of ways of identifying network traffic to make it visible to only the appropriate devices. By isolating network traffic in this way, the same physical or infrastructure network can support multiple virtual networks. For example, the Ethernet technology uses VLAN IDs (or tags) for this purpose. Similarly, ATM uses VPI and VCI; Frame Relay uses DLCI; and MPLS uses VPLS IDs. In UIM, you use flow identifiers to represent these various types of network addresses.
You can define Flow Identifier specifications to fit your business and technological requirements. UIM provides a number of Flow Identifier specifications in the Ethernet reference cartridge.
