Net neutrality has been heavily debated as a potential Internet regulation. Advocates have expressed concerns about the pricing power of ISPs, which might be used to discriminate Content Providers (CPs), and consequently destroy innovations at the edge of the Internet and hurt the user welfare. However, without service differentiation, ISPs do not have incentives to expand infrastructure capacities...
In home networks, a variety of smart devices are connected to a WiFi access point (AP) and the oversized buffer of the AP causes high latency/delay jitter and reduced network throughput (known as the bufferbloat problem). To mitigate this problem, appropriate active queue management (AQM) algorithms should be implemented at the AP. In this paper, we conduct extensive simulation study on the performance...
Transaction delay is in many cases the most important performance metric of networked applications because it is a manifestation of both network and end host (client or server) performance and it often directly reflects the user experience. We introduce TimeAudit, a tool for enterprise network administrators that analyzes transaction delays from TCP/IP packet header traces. TimeAudit computes the...
Content Delivery over the Internet continues to be a challenge as there is no centralized control system [1]. Software Defined Networking has paved the way to provide this control of network traffic. OpenFlow is now being standardized as part of the Open Networking Foundation, and Software Defined Exchange provides a framework to use OpenFlow for multidomain routing. Prototype deployments of Software...
Over current long fat networks, enough throughput cannot be obtained using TCP Reno, which is the classical standard TCP congestion avoidance algorithm. For this reason, many high performance TCPs have been proposed, such as Compound TCP and CUBIC TCP. Then, these proposals have caused a new issue, which is fairness among these modern TCPs. For this issue, several fairness evaluations and some proposals...
Many scholars would agree that, had it not been for the partition table, the visualization of journaling file syste ms might never have occurred. In this work, we confirm the typical unification of Internet QoS and red-black trees, whi ch embodies the typical principles of hardware and architecture. This at first glance seems counterintuitive but is buffetted by prior work in the field. In order to...
CUBIC TPC is a congestion control algorithm for TCP. It is the current default TCP algorithm in Linux. Because many Internet servers, such as web servers, are running on Linux operating system, keeping throughput obtained with this TCP algorithm enough is quite important. Then, many performance studies have been published. However, most of these studies were based on network simulators. Thus, evaluations...
In 6LoWPAN, all the nodes access the Internet through the gateways, which are on the border to legacy IP networks and handle ingress and egress data traffic. A gateway as the traffic center may easily become the congestion-concentrated point so that causes reliability problems and performance degradation. Gateway bottleneck is the dominant reason for network capacity and throughput constriction, since...
High quality online video streaming, both live and on-demand, has become an essential part of consumers' every-day lives. The popularity of video streaming has placed a heavy burden on the network infrastructure that now has to transfer an enormous amount of data very quickly to the end-user. To further exacerbate the situation, the Video-on-Demand (VoD) distribution paradigm uses a unicast independent...
The shortcomings of today's Internet and the high demand for complex and sophisticated applications and services drive a very interesting and novel research area called Future Internet. The area of Future Internet research focuses on developing a new network with similar magnitude as today's Internet but with more demanding and complex design goals and specifications. It strives to solve the issues...
6in4 is the IPv4 to IPv6 migration technique that uses tunneling to encapsulate IPv6 packets over configured IPv4 communication links. This paper attempts to evaluate and compare performance parameters like Throughput, IP End-to-End Delay and Response Time of different applications running on the internet in IPv4, IPv6 and 6in4 manual tunneling environments. The applications that we are modeling are...
IP Next Generation (IPng) or IPv6 engineered by IETF is the successor of IPv4, the contemporary version of Internet Protocol. IPv6 is designed to solve the long term performance, reliability and scalability problems of IPv4. Although IPv6 implementation is yet to attain a maturity level, its success will ultimately depend on its implementation in a broader perspective. The IPv6 network migration is...
Network engineers and designers need additional tools to generate network traffic in order to test and evaluate, for instance, application performances or network provisioning. In such a context, traffic characteristics are the most important part of the work. Indeed, it is quite easy to generate traffic, but it is more difficult to produce traffic which can exhibit real characteristics such as the...
Multipath TCP is an experimental transport protocol with remarkable recent past and non-negligible future potential. It has been standardized recently, however the evaluation studies focus only on a limited set of isolated use-cases and a comprehensive analysis or a feasible path of Internet-wide adoption is still missing. This is mostly because in the current networking practice it is unusual to...
Advances in low-power wireless communications and micro-electronics make a great impact on a transportation system and pervasive deployment of road-side units (RSU) is promising to provide drive-thru Internet to vehicular users anytime and anywhere. Downloading data packets from the RSU, however, is not always reliable because of high mobility of vehicles and high contention among vehicular users...
Today's Internet does not provide an exchange of information between applications and networks, which may result in poor application performance. Concepts such as application-aware networking or network-aware application programming try to overcome these limitations. The introduction of Software-Defined Networking (SDN) opens a path towards the realization of an enhanced interaction between networks...
The VoC network through DNS server makes users to be based on a web server, facilitates users to carry out a VoIP registration, to get and to change an account, and also to see others who have been registered and are active in this VoC network. The infrastructure of VoC network uses asterisk as a VoIP server and playVoIP as a web server interface, which programs are included in a server VoC. The VoC...
NDN enables routers to cache received contents for future requests to reduce upstream traffic. To this end, various caching policies are proposed, typically based on some notion of content popularity, e.g., LFU. But these policies simply assume the availability of content popularity information without elaborating how that information is obtained and maintained in routers. Towards line-speed and accurate...
We demonstrate the practical implementation of a schema for Smart Grid Last Mile (SGLM) traffic management in leased Internet access networks, based on well-known queue management and traffic marking algorithms such as Random Early Drop and Token Bucket. Internet access links are often over-provisioned, with much higher installed capacity than user needs, so domestic applications do not compete for...
In large scale Internet platforms, measuring the available bandwidth between nodes of the platform is difficult and costly. However, resource optimization for large-scale Internet applications (like broadcasting a message or organizing master/slave computations) requires to have predictions about the performance of the platform, and especially about available bandwidth. In this paper, we analyze the...
