In addition to rationally managing network access, we also use the access control list to prevent viruses. We can filter ports that are commonly used for virus spreading, discard the packets that use these ports. This effectively prevents virus attacks. However, even the scientific

called AC. We also use the word "WTP" to refer to AP (including fat, thin, or moderate ). The IETF's Wireless Access Point Control and configuration (CAPWAP) team is defining interfaces and protocols between the AP and Its controlled WTP. This section uses the CAPWAP framework to describe the interfaces between AC and WTP. [3, 4, 5] The following functions can be implemented through an interface between th

For example 20 MPEG-1 (1.5 M) IP/TV channels, if the multicast function is used, the user selects a channel, only the specified channel 1.5 M traffic is sent to his PC. If it is broadcast, 30 M (1.5X20) of traffic will be sent to the user's PC. High-Performance Ma
