Service Performance Testing Method for IPTV Based on Wireless Channel
The study focused on the service performance testing method for broadband wireless mobile communication systems and proposed a testing solution for wireless channel.The solution was implemented to test a practical indoor and outdoor service performance and obtained the packet loss rate,latency and jitter.Based on the tested data,the performances of the system were analyzed,and the operability of the method was verified.
This paper studies about the policy enforcement of security router platform with Intel IXP2800 network processor. IXP2800 network processor improves networking processing. Security router platform has packet filtering, intrusion detection and VPN functions. They are implemented at microengines of network processor. Security policy enforcement of router is implemented at Xscale core of network processor. Security router platform communicates the security policies with management system through COPS protocol. Security router platform analyzes the whole security conditions of network and preserves the network services from attacks according to policy. Security policies are packet filtering policy, intrusion detection policy, access control policy and VPN policy.
