The Datagram Congestion Control Protocol (DCCP) [1] is being proposed by IETF as a transport protocol to support multimedia traffic. Two congestion controls mechanisms have been proposed so far for DCCP, namely TCP-Like [2] and TCP-Friendly Rate Control ...

In this paper, we describe an ongoing work focusing on a level of adaptation for multimedia services instantiated by a mobile user. The focus is based on video streaming over Internet, for which neither quality of service nor guarantee of resources in ...

One of the challenging issues in the environment of large networks with routing algorithms, including quality of service (QoS) routing algorithms is scalability network. This paper studies partitioning as a technique towards scaling QoS routing ...

Position-based routing suffers from inaccurate neighbor positions, especially at low beaconing rates. In this paper we propose to add dead-reckoning to the forwarder selection process to predict the positions of neighboring nodes. We have carried out ...

The design and development process of communication protocols and real-time systems and particularly transport protocol mechanisms requires adequate methodology and efficient instrumental support. In this paper, an extensible and QoS-oriented ...

Multiple areas in OSPF have been introduced to improve the scalability of IGP routing in large networks. The principle is to partition the links of the network into areas, each link belonging to a single area. In this paper, we show that the way OSPF ...

Session Initiation Protocol (SIP) is a new signaling protocol adopted by the 3rd Generation Partnership Project (3GPP) for the IP Multimedia Subsystem (IMS). SIP is used to establish and release sessions between end systems. SIP will play a determinant ...

We present AntNet-QoS, a novel approach that taking inspiration from the Ant Colony Optimization (ACO) framework, and in particular from the AntNet routing algorithm, allows dynamic scheduling, forwarding and link sharing among multiple packet classes ...

The computer society has not yet agreed on a standard method to measure data security and consequently to date no specific security metric has been defined for routing purposes. This paper used access control, authentication and cryptography to define ...

While the applications using the Internet have changed over time, TCP is still the dominating transport protocol that carries over 90% of the total traffic. Throughput is the key performance metric for long TCP connections. The achieved throughput ...

In recent years, much work has been done on attempting to scale multicast data transmission to hundreds or thousands of receivers. There are, however, many situations where an application might involve transmission to just ten or twenty sites. The ...

Content distribution is becoming increasingly important with the decreasing cost of broadband access and the growing number of Internet users. Many of today's content distribution applications require a group communication infrastructure. Source-...

This paper addresses the provision of proportional differentiated services to an arbitrary number of traffic classes in terms of the class packet loss probability measured between the ingress node and the egress node of an OBS network. Our solution ...

Dynamic networks appear in several contexts: QoS routing faces the difficult problem of accurately and efficiently maintaining, distributing and updating network state information, and in wireless ad hoc networking, signal strength fluctuations ...

The separation of intradomain and interdomain routing has been a key feature of the Internet's routing architecture from the early days of the ARPAnet. However, the appropriate "division of labor" between the two protocols becomes unclear when an ...

There are a large number of large-scale Ethernet-based local and metropolitan area networks in use. A significant reason for this prolific deployment is the relatively simple manner in which they can be configured and deployed. A critical service on ...

We first show by measurements that BGP peering links fail as frequently as intradomain links and usually for short periods of time. We propose a new fast-reroute technique where routers are prepared to react quickly to interdomain link failures. For ...
