Chinese broadband network is developing rapidly but still far from all coverage for countryside areas, the island of information. Current distance education content is of large multi-media with large bandwidth. So it is critical for education platform to deliver the massive content timely and effectively, yet low-cost, even to the terminals without broadband coverage. Analyzed current mobile Internet...
Access to Internet is still a challenge in the area without fully network-coverage. Limited to a predictable environment (such as trains), the problem can be simplify and be solved partially with the proposed general k-anycast routing and Delay and Disruption Tolerant Networking (Ganycast). How to forward the packets efficiently is core issue of Ganycast. Access router information matrixes were proposed...
K-anycast in disruption tolerant network (DTN) can multi-path custody transfer packets for the area without fully network-coverage Internet access, after gotten circumstance information. In this paper, connection judgment logic is proposed for distinguishing mobile circumstance. Probabilistic routing protocols have poor performance in the mobile node cyclical movement environment, so TTL equivalent...
DHT (Distributed Hash Table) algorithms are very efficient for distributed data storage and retrieval. As one kind of P2P overlay, DHT overlay also has the advantages of high reliability, high scalability and low cost. DHT has not only been applied to form user nodes' overlays, but also been proposed to form DHT-based server farms, such as DHT-based SIP server farm, HSS server farm, DNS server farm,...
