“…The goal of CRAM [7] is similar to that of SPAM: to enable native cut-through for cells while enabling the interleaving of cells from the same or different senders. For that, both SPAM and CRAM identify each cell in order to avoid cell mix up at the destination.…”

Multicast service is a n important part of a n y modern routing architecture. Motivations for many-to-many multicast include general unpredictability of membership in m a n y real applications; simplicity of the rendezvous f o r the application programmer; and low cost t o end syst e m s and switches in t e m s of state t o maintain for the delivery tree. Shared trees have a n even greater advantage over source based trees in the latter respect. Shared trees (as in the CBT model for Internet) are supported in the form of a single logical VC per multicast group (i.e., multipoint-to-multipoint VC or m p -m p V C ) in the A T M networks. Recently C R A M , SEAM and S P A M have been proposed f o r supporting m p -m pVC. T h e work in this paper does a performance comparison of these three schemes, with respect to buffer requirements, end-to-end delay, packet jitter and t r a f i c overhead. Our evaluation is carried out through extensive simulations with digerent topologies and sender traffic types.

“…With AAL5 as adaptation layer it has to be taken care that senders send in turn, not at the same time, -or at least that their packets do not overlap on intermediary linksbecause otherwise it is impossible to correctly reassemble the packets sent, unless each packet covers just a single ATM cell, which in general is not a valid assumption. This restriction is resolved in CRAM [15], which sends resource management (RM) cells (originally introduced by the ATM Available Bit-Rate (ABR) service) in front of user data frames to carry information about the sender of the frame. These RM cells are inserted at merge points.…”

&KDUDFWHULVWLFV RI PXOWLSHHU FRPPXQLFD WLRQMultipeer communication is different from other communication relations (unicast (1:1), multicast (1:N), concast (M:1)) in several aspects, some of which are discussed below. These aspects are often not disjoint, but closely related. An approach using a token to pass the right to send, e.g., can use appropriate methods for ordering of messages, bandwidth allocation of senders, and failure detection.
