Timely and accurate traffic classification and application characterization are becoming increasingly important with many applications in wired and wireless networks, e.g., traffic engineering, security monitoring, and quality of service (QoS). In particular, Software Defined Networking (SDN) is a new networking paradigm that has great impact on future IP networks and 5G wireless networks. In SDN...
Emerging Information-Centric Networking (ICN) architectures seek to optimally utilize both bandwidth and storage for efficient content distribution over the network. The Virtual Interest Packet (VIP) framework has been proposed to enable joint design of forwarding, caching, and congestion control strategies within the Named Data Networking (NDN) architecture. While the existing VIP algorithms exhibit...
In this letter, we propose a novel cooperative caching scheme for the next-generation Internet — content oriented networking (CON), trying to minimize the content access delay for mobile users. We formulate the caching problem as a mixed integer programming model and propose a heuristic solution based on Lagrangian relaxation. Simulation results show that this scheme can greatly reduce content access...
Distributed Web crawling (DWC) over DHTs is proposed to solve the bottlenecks in the traditional Web crawling. The core of this kind of system is its fully distributed task scheduling mechanism in which the crawlers are treated as peers and the crawlees are treated as resources maintained by the peers. A system model based on the content addressable network (CAN) can further optimize the scheduling...
In order to solve task scheduling and load balancing problems of distributed search engines, a GNP-based scheduling strategy for distributed crawling and a load balancing method are proposed in this paper. Internet distance estimating mechanism is adopted as a replacement for large-scale network distance measurement, which not only improves response speed of the system, but also reduces loads on WAN...
