Abstract:Common service software implementing DHCP protocol lacks the network-access authentication, which makes DHCP network insecure, and to overcome this shortcoming and ensure the success of terminal and security of access, it has to deploy additional commercial software. However, these software need some plug-ins’ support, and any one of these plug-ins is not qualified because of heterogeneity of network and terminal. To meet demands of diverse-terminal heterogeneous-network secure access, a self-management access system was designed which provides authentication function based on dynamic MAC address binding. Besides, this system provides a self-management module which has a vital function for registering and managing MAC address and querying network-access records, and a DHCP-configure file module which aims to dynamically generate and conveniently manage DHCP-Server configuration file. It is flexible and ease-configure without any plug-in.

It also improves the network resource utilization, reduces the load of the central media server. The experiments show that IMS-based overlay network content distribution mechanism has a significant advantage compared with the traditional media server content distribution mechanism.

Abstract:VLIW DSP obtain time parallelism through software pipelining, and obtain space parallelism through instruction clustering. The essence of clustering is resource allocation. Traditional clustering assumes that one instruction assigns to certain cluster, but that does not applicable to some architecture offering SIMD instructions. This article proposes an algorithm based on evaluation model can do well with the problem of clustering for ordinary instructions and SIMD instructions. By scheduling inter-cluster transfer instruction, we synthesize inter-cluster double word transfer instruction. With the help of SIMD instruction, inter-cluster double word transfer instruction and good clustering policy decision, we make the schedule latency shorter. For many DSP programs, comparing with no clustering, we obtain 2 ~ 3 times increase in performance, comparing with clustering algorithm based on register allocation, we obtain 7~10% increase in performance.
