Increasing trend of peering at Internet exchange points (IXPs) provides a topological and network management advantage to the Internet service providers (ISPs) that is otherwise not possible through individual peering arrangements with their neighboring domains. ISPs keep analyzing potential advantages to peer at geographically diversified IXPs. Increasing degree of multihoming in ISPs requires extensive...
Flow-Aware Networking (FAN), after a few years of limited interest becomes again a promising concept for the Future Internet. In this paper, we present an integrated approach to ensure efficient and reliable transmission in FAN. The proposed solution is based on the central controller, which enhances an operation of particular mechanisms which compose the integrated system. The key mechanisms of the...
Traditional routing in the Internet is best-effort. Path differentiation including multipath routing is a promising technique to be used for meeting QoS requirements of media-intensive applications. Since different paths have different characteristics in terms of latency, availability and bandwidth, they offer flexibility in QoS and congestion control. Additionally protection techniques can be used...
Video traffic, which represents an increasing fraction of the Internet traffic, requires end-to-end quality of service (QoS) guarantees for inter-domain routing. However, providing such guarantees remains a challenge essentially because it requires a strong and fair cooperation among the different network operators or Autonomous Systems (ASes), crossed by the traffic. Having a single AS on the path...
To study Internet's routing behavior on the granularity of Autonomous Systems (ASes), one needs to understand inter-domain routing policy. Routing policy changes over time, and may cause route oscillation, network congestion, and other problems. However, there are few works on routing policy changes and their impact on BGP's routing behaviors. In this paper, we model inter-domain routing policy as...
Internet is so popular that nearly everybody using it every day. Current Internet shows some characteristics of intelligent. For example, it can help people find the proper resources using semantic search. So this paper focuses on the wisdom of Internet. Firstly, the definition and relationship among information, knowledge and wisdom are introduced. Then, the definition of Internet information, Internet...
Take a research in depth on the modeling problem of service path selection based on SON. Firstly, the optimal model is built with the optimal goal of balanced loading and with the functional constraints of users for composed service and multi-QoS constraints. Then the layered method and improved Ant algorithm are adopted to solve this problem. Finally, a simulated emulation is made to the algorithm,...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
