An integral part of any network Quality of Service (QoS) system are its QoS declarations. QoS declarations consist of service classes, parameters, and specification units. QoS declarations are a component of the QoS architecture, as such they are a source of heterogeneity stemming from the fact that different QoS systems may be based on different QoS architectures and thus use different QoS dec...

Network routing platforms and Internet firewalls of the next decade will be radically different than the platforms of today. They will contain modular components that can be dynamically reconfigured over the Internet. But, unlike the active networks that are in the research labs today, these new platforms will not suffer from the performance penalty of processing packets in software. These plat...

In the design of mobile ad hoc networks, a challenging problem is how to route information reliably and efficiently from one node to another in moderate to high level of mobility. Due to mobility, limited residual energy of the node, selection of stable and durable path for the communication is the challenge. Also remaining queuing capacity is also affected on the packet loss. Many proposals ha...

Recent initiatives to add mobility to the Internet and packet data services in third-generation (3G) cellular systems are being considered as candidate solutions for the delivery of IP data to mobile users. Transport Control Protocol (TCP) will continue to be the most widely used transport protocol for a certain duration in 3G cellular Internet networks. Initially designed for high-speed wireli...

active queue management (aqm) plays an important role in the internet congestion control. it tries to enhance congestion control, and to achieve tradeoff between bottleneck utilization and delay. random early detection (red) is the most popular active queue management algorithm that has been implemented in the in internet routers and is trying to supply low delay and low packet loss. red algori...

A new receiver-based playout scheduling scheme is proposed, which estimates the network delay from past statistics and adaptively adjusts the playout time of the voice packets. In contrast to previous work, the adjustment is not only performed in between talkspurts, but also within the talkspurts in a highly dynamic way. Proper reconstruction of continuous output speech is achieved by scaling i...

Temporary link failures and route changes occur frequently in mobile ad hoc networks. Since TCP assumes that all packet losses are due to network congestion, TCP does not show satisfactory performance in ad hoc networks. In this paper, we propose a simple and new mechanism called TSR, TCP-aware Source Routing, which can improve TCP performance in mobile ad hoc networks. By reducing the number o...

Explicit Congestion Notification is a recently proposed congestion avoidance scheme for IP networks. ECN uses marking packets instead of dropping them in case of incipient congestion. Avoiding packet drops saves network bandwidth and allows congestion signals to be propagated faster. In the paper, we present the results of detailed simulations that we have performed to assess the gain TCP appli...
