Dept. of Computer, Xi’an University of Science and Technology, Xi’an 710054) AbstractUnited Threat Management(UTM) uses many security technologies, however deep inspection for application layer leads to lost performance heavily and big latency, and it becomes a bottleneck for the whole network. This article analyzes two popular solutions, and gives a new architecture for UTM based on the NetChannel technology. The solution resolves the performance and latency issues in MultiCore/MultiProc- essor architecture.
