MPLS using LDP and ATM VC Switching

The Multiprotocol Label Switching (MPLS) Architecture [1] discusses a way in which Asynchronous Transfer Mode (ATM) switches may be used as Label Switching Routers. The ATM switches run network layer routing algorithms (such as Open Shortest Path First (OSPF), Intermediate System to Intermediate System (IS-IS), etc.), and their data forwarding is based on the results of these routing algorithms...

Improved VC-Merging for Multiway Communications in ATM Networks

The routing and signaling protocols for supporting multipoint-to-multipoint connections in ATM networks have been presented earlier. VP-Merge and VC-Merge techniques have been proposed as the likely candidates for resolving the sender identification problem associated with these connections. The additional buffer requirements in the VC-Merge mechanism and the excessive use of VPI/VCI space in t...

AAL5X ATM Adaptation Layer 5 eXtension for Efficient VC Merging over ATM Networks

The realization of multiway group communications and scaleable layer 3 switching over ATM networks requires merging of virtual connections to be possible. This capability, known as VC merging, cannot be provided by ATM networks which use a standard ATM protocol stack on both switches and stations. This paper describes AAL5X, an extension to the ATM Adaptation Layer 5 (AAL5) that allows for VC m...

Impact of VC Merging on Buffer Requirements in ATM Networks

For the implementation of multipoint-to-point connections in ATM, various approaches exist, each with its own advantages and disadvantages. VP-based methods require unique sender identi cation but they do not require reassembly in merging points. In contrast, VC-based methods do not require unique sender identi cation but they do require reassembly in merging points. It is likely that VC mergin...
