Traffic Tunnel Management in Cloud-based Flow Security System

Abstract

Considering the increasingly serious problem of Internet security recently, Cloud-based Flow Security System(CFS) has been built as a solution to the Internet security application, providing convenient and effective application and content level security for enterprise users by means of cloud services. Under the CFS system, this paper developed custom function modules to achieve unified management of network nodes and GRE tunnel between the nodes, management of the switch data forwarding, and real-time monitoring of the state of the tunnel in the control platform, accomplished the design scheme of combining the load balancing algorithm with the unified management of the tunnel, realized the efficient allocation of the network nodes in the large-scale network environment and improved the network flexibility.
