Abstract
In this paper, we propose a network level abstraction called α-channel to support the requirements of real-time applications, based on resource reservation and fixed routing. An α-channel represents a simplex, end-to-end communication channel with guaranteed service characteristics, between two entities. Based on the value of α, we define three classes of α-channels, namely a deterministic α-channel (α = 1), a statistical (0<α<l) and a besteffort (α=0). The semantics of these classes derive from the percentage of on-time reliability that need to be supported by the α-channel.
The primary attribute supported by the α-channel is the on-time reliability. At the α-channel establishment phase, the sender specifies the end-to-end delay of each packet, the maximum number of packets to be generated during this delay, and the on-time reliability required. We described the basic scheme that our model uses to verify the feasibility of accepting a new α-channel with guaranteed performance. A formal description of the proposed model and a sketch of the proof of its correctness is provided. We also present the preliminary results of a simulation experiment implementing the basic functionalities of the proposed scheme.
