The application based on P2P technology is one of the most important application of the Internet, but it is often affected by the node failure or abnormal nodes exit. In P2P network, node failure can cause data loss and invalid index, then reduce QoS (Quality of Service) of P2P network, lead to reputation system crashes and so on. Therefore the P2P node failure handling and recovery method can effectively...
High-speed switching, QoS (quality of service) provisioning, security, and mobility are main challenges faced with existing networks and to be confronted by next generation network (NGN) researchers and developers. To address these challenges, a new architecture called SUPANET (single-layer user-data switching platform architecture network) has been developed. But most of works on SUPANET have been...
This paper proposes a novel dynamic bandwidth allocation method based on a new switch technology named Ethernet-oriented physical frame timeslot switching (EPFTS). Based on the features of EPFTS, the bandwidth allocation is changed to quota allocation for manageable quality of service (QoS). The proposed method is composed of a quota allocation strategy and a dynamic quota scheduling policy called...
High-speed switching, QoS provisioning, security, and mobility are main challenges faced with existing networks and to be confronted by NGN researchers and developers. To address these challenges, SUPANET has been proposed in recent years. But all works on SUPANET have been mainly devoted to high-speed switching and QoS issues, so far, there is no research on the mobility management of SUPANET. To...
Guarantee of QoS (quality of service) and mobility management are important research areas in NGN (next generation networks). Most people have been taking a route of mobile IP over MPLS (MIoM) to meet such challenge. However, MIoM has a drawback considering that MPLS itself does not have any direct control over transmission at the physical layer, instead, it has to rely on existing data link layer...
High-speed switching, QoS provisioning, security, and mobility are main challenges faced with existing networks and to be confronted by NGN researchers and developers. This paper promotes a BSF-OES strategy (Backbone Substrate First, Outwards Expansion Second) towards NGN with a redefined out-of-band concept. In other words, we shall first focus on the backbone subnetwork with an emphasis on building...
