Future networks are envisioned to satisfy the user needs and improve their quality of experience. This requires the networks to support context-aware information, where context of the user, session, network and environment will greatly influence the way the session is delivered: new approaches are required to deal with the overall context information and network reaction to constantly context changes...
Anycast communication is a new Internet service defined in IPv6, and it can make a host communication with the one ldquonearestrdquo member in a group of servers. The anycast routing problem with multiple QoS constrained is known to be NP-complete problem and we can't get satisfying results when using the precise method in polynomial time. In this paper, a QoS anycast routing algorithm based on ant...
With the advent of various QoS technologies, various traffic classes with different QoS requirements are supported on an integrated IP network. As for the multiservice IP networks, the dominant factor in the cost of provisioning a particular service is dependent on the minimum network bandwidth allocated in the network with QoS requirements satisfied. Therefore, to optimally partition bandwidth resource,...
