A pay load-analysis approach to identification and measurement of peer-to-peer (P2P) network services is proposed. The proposed approach effectively and efficiently identifies the complicated traffic caused by P2P network services. The feature extraction, pay load analysis and dynamic measurement are the three pillars of the proposed approach. The dynamics of BT connections are featured to generalize...
In this paper, we propose a group-oriented management of key trees. Traditional approach to manage key tress such as TGDH cannot retain characteristics of subgroups and it costs a great quantity of exponentiation computation to calculate the group key due to its algorithm. By means of group-oriented management of key trees, we reduce the cost of rekeying and the message size that is consultation to...
In this paper, we propose a QoS-enabled VPN architecture supporting a new service level agreement (SLA), called mu SLA to allow customer to specify QoS requirement. Such a QoS requirement is in terms of VPN total bandwidth and real-time micro-flow bandwidth. The proposed architecture is based on VPN hose model over DiffServ network and on logical bandwidth partitions at edge routers into various classes...
