Operation of the LAN Emulation

383

Address Resolution

Address resolution is the procedure by which a LEC associates a LAN 
destination with the ATM address of another LEC or the BUS. Address 
resolution allows clients to set up data direct VCCs to carry frames. (See 
Figure 24.)

Figure 24   

Address Resolution

Connection

Management

In Switched Virtual Connection (SVC) environments, the LAN Emulation 
entities (LEC, LES and BUS) set up connections between each other using 
UNI signaling.
