The idea of ID/Locator separation has been suggested to solve the routing scalability and mobility problems in the Internet. Some solutions have been proposed based on this idea, such as LISP and HIP. However these solutions are either bandwidth inefficient or difficult to deploy. In this paper, we propose a novel network architecture based on the idea of ID/Locator separation, which can easily integrate...
Low cost, high bandwidth Internet connectivity has made Video-on-Demand (VoD) one of the most significant new age technologies being adopted by ever-growing users. Video applications such as online video streaming, video conferencing and many others are being increasingly used. The increased in IP based video applications has resulted in more traffic over IP networks. Hence, there is a need for efficient...
Traffic engineering is a mechanism to use network resources more efficiently. Network operators use TE to obtain different objectives such as load balancing, congestion avoidance and average delay reduction. Plane IP routing protocols such as OSPF, a popular intradomain routing protocol, are believed to be insufficient for TE. OSPF is based on the shortest path algorithm in which link weights are...
QoS Routing Algorithm is a routing algorithm for finding the shortest path that satisfies the QoS requirements of the end users. While finding the shortest path this uses some of improved ideas for effectively finding the shortest path with required QoS measures. Exactly the QoS routing algorithm is a kind of multi constrained routing algorithm where more than one link components are taken into considerations...
Ever increasing demand for more bandwidth over the Internet has lead to the development of many new technologies and architectures. Among these, Hybrid of Wireless and Optical networks have become increasingly important because of their “mobility” and “flexibility” in the wireless part and “robustness” and “high capacity”...
Peer-to-peer (P2P) based content distribution networks (CDNs), e.g., BitTorrent, are widely used in the today's Internet. Since all peers interested in a specific content provide storage and upload capacity those CDNs facilitate a cheap and easy distribution of large amounts of data. However, they generate a lot of costs for Internet Service Providers (ISPs) as normal users also act as a source for...
Unlike traditional routing schemes that route all traffic along a single path, multipath routing strategies split the traffic among several paths in order to ease congestion. It has been widely recognized that multipath routing can be fundamentally more efficient than the traditional approach of routing along single paths. aiming at the increasing network traffic and the deficity that the former Ant...
Recently, scaling problems faced by today's Internet are attracting more and more attentions. It is commonly recognized that separating IP address into identifier and locator is an effective way to solve the problem. How to map identity onto locator is a critical challenge for the locator/ID separation network. We present a resolution of mapping service based on one-hop DHT to resolve a locator for...
Previously, we studied the performance of transport layer multihoming (e.g., STCP). Using the emulated application of the bulk data transfer, we investigate existing overlay multicast schemes and find that all of them have a inherit performance limitation caused by tansport layer singlehoming (e.g., TCP). Based on this, we design a new overlay multicast architucture named the Hierarchy Overlay Multicast...
Dependable communications are needed by some users. When failures disrupt their communications, recovery mechanisms are needed to bypass them and preserve communications delivery. This article studies a recovery mechanism deployed by users themselves, which suits to their needs. We propose a system based on end-to-end routing in an overlay network to recover users' communications. We present this...
The resource of DTN (Delay Tolerant Network) is constrained and its links are unstable, so the states of network can't be fed back in time to the source node of data. The rate control mechanism and window mechanism of congestion control can't solve the congestion problem of DTN. The paper has proposed A DTN Congestion Control Mechanism Based on Distributed Storage (DCM). When the congestion of a DTN...
The Internet is witnessing explosive growth in traffic due to bulk content transfers, such as multimedia and software downloads, and online sharing of personal, commercial, and scientific data. Yet bulk data transfers remain very expensive and inefficient. As a result, huge amounts of digital data continue to be delivered outside of the Internet using hard drives, optical media or tapes. Meanwhile,...
Recently broadcasts on the Internet, Internet movie theaters and the growing stream of service-oriented Internet services have increased. The bottleneck created to enhance network performance to meet the needs of service users has also increased, while accommodating the needs of the system for the performance of multimedia server capacity cannot meet the server specifications. To provide Distributed...
This paper propose a novel approach to utilize the network to store data in form of floating IP packets. Network could play the role of temporary storage in certain applications and packets could be retained in the network in a closed routing loop. This approach which is called Data Storage Technique on IP Networks (DSTN) could be considered as one of the new applications of future IP networks. With...
Providing the required quality of service (QoS) for clients in a wireless mesh network (WMN) is a challenging task. This is due to the complex architecture of the WMN and unpredictable behavior of the wireless links and the intermediate nodes. This can be alleviated by introducing a cognitive mechanism within the WMN. In this paper, a WMN is developed, where the data traffic is forwarded in a cognitive...
Multipath inter-domain routing can solve many technical flaws which have been exposed in BGP, but the market-driven factors have more direct relationship with its deployment. In order to analyze impact of these market-driven elements, this paper established an optimization model for Internet service provider (ISP) revenues based on user's utility function. Then, the solution using Lagrange multiplier...
Aiming at improving the performance of relay transmission in multi-flow streaming overlay networks, a performance evaluation model to optimize the global weighted average latency was proposed. This model supports multiple senders and multiple receivers. A distributed heuristic allocation algorithm was proposed to optimize the transmission performance. In this algorithm, the bottleneck bandwidth shared...
Base on the QOS requirements of modern broadband networking, the paper presents our recent research on QOSPF in the on-demand computing over the traditional OSPF. The disadvantage in a distributed routing protocol under the QOS requirement is firstly discussed; then a new QOSPF which supports the QOS routing scheme is proposed. The advantage of new approach is demonstrated in the simulation of OSPF...
To avoid congestion caused by some nodes overloaded and mesh points (MPs) becoming bottleneck in wireless mesh networks (WMNs), this paper proposed a new routing protocol called CLDSR-LB (cross-layer dynamic source routing protocol with load balancing). In order to avoid nodes overloaded, CLDSR-LB utilizes the idea of multi-metric and cross-layer and selects an optimal route by estimating the residual...
Multi-nexthop routing mechanisms is the key point in network congestion, and the essential question is how to forward packets among multi-nexthop to reach equiponderant forwarding. This paper proposes an equiponderant forwarding strategy in multi-nexthop routing, which forwards the packets according to the actual capability of each node, and resolves the equiponderant forwarding problem of multi-nexthop...
