Abstract
An asynchronous transfer mode (ATM) address compression method uses a PHY ID (14). The PHY ID (14) is provided before the transmission of a 53-byte ATM data cell (12, 16, and 18). The PHY ID (14) (also referred to as a link) is used to access a link table (20). The link table (20) contains address compression mode information which allows for many address compression modes and an enable bit, an address pointer, and a mask value which are used to both reduce ATM addressing bits and identify a virtual path table/entry in the ATM system. In some address compression modes, the identified virtual path contains the ingress connection identifier (ICI) which identifies a physical data routing path in the ATM system. In other address compression modes, further address compression of virtual channel identifiers is required beyond the virtual path tables in order to identify a virtual channel table/entry which then contains the ICI.
