....service is essential in multi party multimedia applications. There are two possible approaches to the advanced reservation: 1) a centralized approach where an advanced reservation server exists, and (2) a distributed approach where each node on the channel s path remembers the reservations [13]. Resource Reservation Allocation Functions Reservation allocation of resources can be made either in a pessimistic or in an optimistic way: ffl The pessimistic approach avoids resource conflicts by making reservations for the worst case, e.g. reservation for the longest processing time of the ....
....using a proper load balancing policy. One possibility for providing such a policy is to employ the following mechanisms together: routing, resource monitoring (detecting load changes) load balancing control (making a decision to re route a connection) and dynamic re routing (changing the route) [13]. The routing mechanism implements the routing algorithm which selects a route in adherence to certain routing constraints. The resource monitoring mechanism monitors the appropriate network performance and reports it to the load balancing control. The load balancing control mechanism receives ....

....service is essential in multi party multimedia applications. There are two possible approaches to the advanced reservation: 1) a centralized approach where an advanced reservation server exists, and (2) a distributed approach where each node on the channel s path remembers the reservations [8]. 3.4 Resource Deallocation After the transmission of media data, resources are deallocated, which means, the CPU, network bandwidth, buffer space must be freed and the connections through which the media flow have to be closed down. The close down process has to be done without disruption of ....
....resource monitoring mechanism and determines whether load balancing can be attempted. If load balancing can be attempted, the routing mechanism provides an alternative route and the transition from the primary route to the alternative route is accomplished using the dynamic re routing mechanism [8]. An alternative approach is to adapt the source rate according to the currently available network resources (source adaptation) This approach requires feedback information from the network to the source which results in graceful degradation in the media quality during periods of congestion. The ....
