    Abstract: A broadband access means with a built-in video service unit. Said built-in video service unit transmits the stored video service to the user terminal through the broadband access means it belongs according to the request of user terminal. Said video service unit comprises a unicast storage module; a unicast forward module, for transmitting the video service stored in the unicast storage module to the user terminal according to the unicast request of the user; a unicast retransmission module, for responding the retransmission request of the user terminal and retransmitting the lost unicast video message to the user terminal; a multicast storage means, for caching the multicast video stream in real time; and a multicast retransmission module, for responding the retransmission request of the user terminal and retransmitting the lost unicast video message to the user terminal via unicast traffic.

    Abstract: The IGMP, especially a method for processing the abnormal multicast service and a system thereof, the method for processing the abnormal multicast service includes: when the message carrying the leave multicast group information of a user terminal/user port is lost, for avoiding abnormal condition caused by the losing, the network equipment finds out the multicast group which the user terminal/user port does not belong to and stops forwarding the traffic of the multicast group to the user terminal/user port. By using the present invention, the multicast protocol stack is not modified, and the serious problem caused by IGMP Leave message losing is solved by the redefined multicast process flow based on the present multicast CAC process mechanism and the standard IGMP protocol. By using this method in the application of IPTV and so on, some problem are solved such as packet losing caused by IGMP Leave message losing, channel switching is unsuccessful, the line bandwidth waste affects the other service, the home network bandwidth is wasted, etc.

    Abstract: A method of a PPP access terminal obtaining a server address of the provider includes: when the PPP access terminal accesses a network through an access server, the access service device sends the provider’s server address to the PPP access terminal; then, after the PPP access terminal has obtained the provider’s server address, it configures the address in local. The invention a method of obtaining the service server and the manager server addresses for the PPP access mode, which method can reduce the configure work in the process of service distribution, save the run cost of the provider. At the same time, the invention can support the roam service. The invention also discloses a PPP access terminal and an access service device.

    Abstract: Embodiments of the present invention provide a network security method and a device. The method includes: receiving, by a network device, a first data packet that includes a first security group tag (SGT), where the first SGT is used to identify a security group to which the first data packet belongs; recording a first correspondence, where the first correspondence is a correspondence between the first SGT and a source IP address of the first data packet; receiving a second data packet, where a destination IP address of the second data packet is the source IP address of the first data packet; acquiring the first SGT according to the destination IP address of the second data packet and the first correspondence; and acquiring, according to the acquired first SGT and a preset second correspondence, a network security policy and executing the policy on the second data packet, where the second correspondence is a correspondence between the first SGT and the network security policy.

    Abstract: The present invention is applicable to the field of code detection, and provides a method and an apparatus for detecting a code change. The method includes: adding a tag to a function to be changed in a source code; and compiling the source code to acquire, according to the tag, position information and relocation information of the function to be changed in the compiled source code. In embodiments of the present invention, a tag is added to a function to be changed; and a source code is compiled into a binary file, and position information and relocation information of the function to be changed in the binary file are acquired by using the tag, so that in subsequent operations, a hot patch file modifies, according to the position information and the relocation information, the function to be changed in software. This is not only technologically simple to implement, but also eliminates the need to compare the source codes before and after the compilation.
