Abstract:

This paper focuses on the challenging problem of integrating real-time traffic with data traffic on the same network, while having predictable quality of service (QoS) guarantees. Predictable QoS guarantees mean both deterministic and probabilistic (with a known probability distribution) functions of loss, delay, and jitter. As of today there are only limited solutions to this problem. This work presents, to the best of our knowledge, the first coherent system solution, for combining, on one hand, bursty data traffic with deterministic no loss due to congestion, and on the other hand, periodic real-time traffic with deterministic bandwidth guarantees, constant jitter, and bounded delay. The principles of this architecture facilitate the implementation of a scalable multimedia system that will combine or integrate distributed/parallel computing (e.g., over a network of PC/workstations) with real-time applications (e.g., interactive video teleconferencing).
