An Active Queue Management (AQM) is a proactive scheme that controls the network congestion by avoiding the congestion before it happened. When implementing AQM in wireless networks several contemporary issues must be considered, such as interference, collisions, multipath-fading, propagation distance, shadowing effects and route failure, and whether the wireless networks is WLAN or other type. Therefore,...
With the rapid development of computer networks, a variety of network applications continue to emerge, resulting in a surge of network data traffic. Therefore, the network congestion becomes more serious. Congestion control is facing many problems, including latency, fairness, stability and so on, especially the instability of the network caused by transmission delay. We introduce the traditional...
BBR is a recently proposed congestion control. Instead of using packet loss as congestion signal, like many currently used congestion controls, it uses an estimate of the available bottleneck link bandwidth to determine its sending rate. BBR tries to provide high link utilization while avoiding to create queues in bottleneck buffers. The original publication of BBR shows that it can deliver superior...
Ad-Hoc and Delay-Tolerant Networks (AHDTNs) can be very useful in environments where more traditional networking technologies fail. Determining the practical effectiveness of AHDTNs can however be challenging. We review design considerations and practical experience with a novel mechanism for monitoring and analyzing the performance of AHDTNs. This new mechanism, AllNet Trace, somewhat resembles a...
Information-Centric Networking (ICN) introduces a paradigm shift from a host centric communication model for Future Internet architectures. It supports the retrieval of a particular content regardless of the physical location of the content. Emergency network in a disaster scenario or disruptive network presents a significant challenge to the ICN deployment. In this paper, we present a Content dIstribution...
TCP LoLa is a new delay-based congestion control that supports both, low queuing delay and high network utilization in high speed wide-area networks. This is particularly useful for traffic mixes consisting of bandwidth demanding and delay sensitive flows (e.g., long file transfer and interactive "web 2.0" traffic). TCP LoLa keeps the queuing delay at the bottleneck link low around a fixed...
The economic aspects of peering and transit interconnections between ISPs have been extensively studied in prior literature. Prior research primarily focuses on the economic issues associated with establishing peering and transit connectivity among ISPs to model interconnection strategies. Performance analysis, on the other hand, while understood intuitively, has not been empirically quantified and...
For reenterable models of IP networks with dynamic routing according to RIP protocol, measuring subnets for QoS parameters evaluation have been essentially modified and extended. Online algorithms of statistical analysis have been specified by colored Petri nets. The mean and variance of the packet delivery time have been evaluated. As a result, the computation precision has grown and an essential...
Aiming at the issues of random delay and delay uncertainty in both the before channel and feedback channel for network control system, the root causes of random delay influence closed-loop control system by case is analysis, and the predictive control method based on neural network to solve the feasibility of existence network random delay in control system closed-loop control has provided. Simulation...
Qos of broadband network is important. ISPs have some methods for evaluate it. But they are not efficient enough. This paper present a new method in which delay and scale of windows of TCP messages are used for evaluating performance of broadband. Comparison between delay or scale of window s of samples is the core idea of the method. There are two kinds of comparison. One is absolute terms of above-mentioned...
IPv6 is an ultimate solution to the Internet address exhaustion. It is believed, the protocol will be requested by not only human but also everything on the earth surface. Furthermore, the improvement on the protocol is important to achieve IP packets transmission efficiently. Processing technology has been improved to become very fast packet processing both in host as well as intermediate systems...
Named Data Networking (NDN) is one of the future Internet architectures and has recently attracted a great deal of attention. NDN adopts named routing and caches all content on routers en-route. It helps to accelerate content distribution and reduces content retrieval latency. However, it also brings a large number of redundant data in the network. In this paper, we propose an in-network caching strategy...
Information centric networking (ICN) is one of the emerging Internet paradigms proposed to overcome the shortcoming of the current host-centric Internet. With ubiquitous in-network caching, ICN can facilitate content delivery and reduce network delay. In this paper, we propose a novel collaborative caching scheme based on routers' position to cache popular videos on the edge routers which are closer...
Consumers frequently get Internet access through a single home gateway. Gateways using conventional FIFO queue management can introduce hundreds or even thousands of milliseconds of additional delay when congested by bulk TCP data transfers. This delay impacts negatively on any latency-sensitive interactive traffic (such as Voice over IP, or First Person Shooter games). Such applications prefer network...
Multimedia streaming is a significant source of Internet traffic, with Netflix and YouTube accounting for more than 50% of North American fixed network peak download traffic in 2016. Dynamic Adaptive Streaming over HTTP (DASH) is a recent standard for live and on-demand video streaming services, where clients adapt the video quality on-the-fly to match the network capacity by requesting multi-rate...
Previous studies have shown the WiFi, as the dominant last hop access to Internet, has become the weakest link in the round-trip network delay. Therefore it is critical to understand and minimize the WiFi interference in order to reduce the WiFi hop delay. For the first time in the literature, this paper defines an intuitive and accurate metric to quantify the impact of interference on each actual...
Content-Centric Networking (CCN) is a promising framework for the next generation Internet architecture, by exploiting ubiquitous in-network caching to minimize content delivery latency and reducing the network traffic. In this paper, we introduce a neighborhood aware mechanism for content caching, named Neighborhood Aware Caching and Interest Dissemination (NACID) that accounts for the popularity...
Networked Music Performance (NMP) constitutes a class of ultra-low delay sensitive applications, allowing geographically separate musicians to perform seamlessly as a tele-orchestra. For this application type, the QoS indicator is the mouth-to-ear delay, which should be kept under 25 milliseconds. The mouth-to-ear delay comprises signal processing latency and network delay. We propose a strong collaboration...
In recent years, wireless networks have become extremely necessary in modern communications. Especially in mobile phones, we are using wireless networks to connect to networks around the world using both cellulars and WLANs. In order to connect to the Internet, mobile phones can connect to the Internet using these wireless network technologies, but, mobile phones cannot select a suitable wireless...
Inter-domain link congestion can be caused by either under-provision or peer disputes. TSLP and M-Lab are two representative network-tomographic methods to detect congestion on inter-domain links. In this work, we propose a performancecost framework to evaluate and compare the two methods via a simulator built atop NS-3. Via detailed simulations, we obtained some insights on the two approaches and...
