Today's Internet is a massive, distributed network which continues to grow in size as globalization takes major role in everyone's life. The problem is complicated by the fact that one cannot rely on the cooperation of individual servers and routers to aid in the collection of network traffic measurements vital for these tasks. Packet Forwarding Priority can have a significant impact on the performance...
The paper proposes a preliminary design of cross-layer quality of service applied to congestion control in future Internet. This is an alternative solution to QoS-aware routing, whenever the infrastructure operator cannot add new resources, and/or when re-routing is not possible. Dedicated software, running in each node, collects a list of local parameters such as available transfer rate and one-way...
Localized Quality of Service (QoS) routing has been recently proposed for supporting the requirements of multimedia applications and satisfying QoS constraints. Localized algorithms avoid the problems associated with the maintenance of global network state by using statistics of flow blocking probabilities. Using local information for routing avoids the overheads of global information with other nodes...

A complete system which ensures reliable transmission of streaming flows in flow-aware networks (FAN) is presented and analyzed in the paper. A new congestion control mechanism, called RPAEF (remove and prioritize in access active elastic flows), is described in detail. It allows for fast acceptance of new streaming flows in the admission control (AC) block of FAN routers. The mechanism of limiting...
In this paper we propose a scalable admission control scheme for the QoS sensitivity traffic in core-stateless networks. In our scheme, the ingress routers perform admissibility test in a fully distributed and parallel fashion for requests by dint of our bandwidth dividing based virtual link mechanism. Then, we introduce a novel two phase token passing mechanism to adaptively optimize the proportion...
Double-layered satellite networks (DLSNs) that consist of low earth orbit (LEO) and medium earth orbit (MEO) satellites are becoming increasingly important since they have higher coverage and better service than single-layered satellite networks. One of the challenges in DLSNs is the development of specialized and efficient routing algorithms. In this paper, virtual topology grouping strategy is improved,...
The continuously growing research to establish the quality of service (QoS) enabled multi-service network architecture has identified several essential mechanisms, among which call admission control (CAC) is assuredly one of the most important ones. This mechanism is responsible for keeping the number of ongoing sessions at the appropriate level in the network to meet the QoS requirements. Due to...
