Dynamic hose technology based virtual special network user port system and signaling control mechanism thereof

Abstract

The invention discloses a dynamic hose technology based VPN user port system, which comprises a CE end and a PE end which are connected through a Hose model interface, wherein the CE end comprises a forward prediction module, an adjustment module, a signaling processing module, a Hose ingress buffer area and a Hose egress buffer area; and the PE end comprises a backward prediction module, an explicit route computation module, a signaling processing module, a Hose information database, a network information database, a Hose egress buffer area and a Hose ingress buffer area. The system can dynamically adjust the size of a Hose port and dynamically update the route so that a VPN user can dynamically adjust the local data traffic; the system improves the communication quality so that resource distribution as required in the network can be realized; and the system reduces the waste of the resources, improve the utilization rate of the resources, and meanwhile can improve the capacity of the network and reduce the congestion rate.

Description

technical field [0001] The invention relates to the field of computer communication networks, in particular to a dynamic Hose technology-based VPN user port system and its signaling control mechanism. Background technique [0002] With the improvement of network capacity and the development of network security technology, the application of virtual private network (VPN) has also been developed rapidly. As the number of VPN users increases, communication patterns between sites become diverse and unpredictable. These factors have all promoted the development of bandwidth-on-demand technology (BoD) and dynamic link technology in VPN. Traditional VPNs generally use a connection method called the user pipe model (pipe model), such as figure 1 . This method will establish a user channel for any two users in the VPN and allocate resources to them, and the resources in the channel are fixed and cannot be shared with other channel resources. Therefore, the pipeline model cannot r...
