Sažetak
While DiffServ architecture solves the scalability problem of QoS provisioning, it fails to be the solution for end-to-end provisioning. A combination of IntServ/RSVP signaling with aggregate traffic handling mechanisms could solve such deficiencies. To obtain quantitative end-to-end guarantees in DiffServ architecture, based on traffic handling mechanisms with aggregate flows, some kind of congestion control through negotiation process (in new SLA creation) is necessary. For N quality-of-service levels (service classes) an efficient heuristic algorithm for end-to-end congestion control is being developed. The problem is seen as an expansion problem of link capacities in given limits from a common source. If the optimal expansion sequence has any expansion value that exceeds allowed limits (link capacity), a new SLA cannot be accepted or must be redefined through a negotiation process.
