....where each protocol provides a well defined interface to those above it, and the simplicity of the network layer. At the lowest level of the stack are the link layer protocols employed by various networking devices like Asynchronous Transfer Mode (ATM) Ethernet (defined by IEEE standard 802.3 [47]) the Point to Point Protocol (PPP) 117] and many others. The link layer enables point to point communication between network interfaces connected to the same physical medium. The network layer abstracts away the vagaries of actual network topology and routes packets between any two end points ....

....to the problem of Medium Access Control [24] The multicast channel constitutes the shared medium and messages sent on the multicast channel are seen by every connected group member. A token mechanism as in token ring is proposed in [22] and random timers with exponential back off as in CSMA CD [25] are used in XTP [23] or the SRM protocol [3, 4] Both classes of solutions are not without disadvantages: Hierarchical approaches require the setup of the hierarchy of subgroups and can not be employed in a scenario like satellite distribution with unicast backward channels. Approaches based on ....

....the same order at every site by this algorithm. Since the entire dependency matrix must be sent with each message, which consists of N vectors of length N, the overhead for each message is N 2 . Therefore, the cost of this algorithm, denoted as cost M , is: cost M = SM (data size) SMN 2 .

....an exponential backoff, due to the mean time of the delay or backoff doubling with every consecutive collision) and then tries again. This paradigm attempts to give all nodes an equal chance to transmit their data, while avoiding subsequent collisions due to repeated retransmission attempts [13, 14]. There is no notion of priority at this level. Thus, transmission of multimedia data on an Ethernet does not get any preference and must compete equally with the transmission of regular data traffic. Ethernet hardware, i.e. network interface, is designed to minimize the load on the CPU. The ....
