The disclosed multimedia business (MMB) system comprises: a server transmitting the display command for video; a MM service device browsing MM menu, capturing the control command and displaying the stored video; and a wireless controller for controlling the display. This invention improves service quality, adds new profit increasing point, and has wide application.

The invention discloses an IDS (Intrusion Detection System) feedback-based SDN (Software Definition Network) flow sampling method and system. A flow is temporally sampled at first through the centralized control capacity of an SDN controller for a network flow, and then is sent to an IDS for primary detection, and whether to continue to sample the flow or not is determined according to a detectionresult of the IDS, thereby improving the sampling accuracy; and under a condition of a limited bandwidth, a flow with a high threat degree is selected for detection as much as possible to improve theutilization rate of the sampling bandwidth and the detection precision. The IDS feedback-based SDN flow sampling method is easy to implement and high in feedback speed; an independent sampling tableis used for implementing sampling, so that the sampling cannot affect normal services; and the method has the deploying capacity in an actual system, in particular in a cloud data center.

The invention discloses a RAM failure detection and processing method, which is applied to the detection and processing of CPU / DSP RAM failure, including: reading the program content in the RAM; if the RAM can be controlled by the high-level of the CPU / DSP Entity access, then compare the program content read with the correct program content by the high-level control entity, when the two are inconsistent, judge that the RAM is invalid and perform data repair; if the RAM cannot be accessed by the high-level CPU / DSP Control entity access, then the program content read by the CPU / DSP is verified by a set verification method, and compared with the correct verification result, when the two are inconsistent, it is judged that the RAM is invalid and Call the police. By adopting the method of the invention, the failure of the CPU / DSP RAM can be detected in time, and corresponding processing measures can be taken in time to minimize the influence caused by the failure of the RAM.

The invention discloses a method for protecting an L2TP network. The method includes: standby L2TP? The LNS backs up the information of the current online L2TP user on the active LNS, the information of the L2TP tunnel corresponding to the L2TP user, and the information of the L2TP session; when the active LNS itself or the link where the active LNS is located fails, the backup The LNS and the active LNS perform active / standby switchover; the standby LNS refreshes routes and forwards user traffic according to the information of the backed up L2TP tunnel and L2TP session. The invention also discloses a protection system of the L2TP network, which ensures that the failure of the LNS device and its link does not affect the normal business of the L2TP user, and that the L2TP user and the LAC cannot perceive the occurrence and recovery of the failure, and realizes the protection of the L2TP network. Troubleshooting can effectively improve the user experience of the L2TP network.

The invention relates to a physical exchange system based on an E1 / T1 circuit, which comprises a main exchange system and a plurality of independent slave exchange systems, wherein each slave exchange system is freely connected with the main exchange system which is connected with a workstation terminal, each salve exchange system is provided with at most 64 paths of E1 / T1 signal interfaces, receives signals from the E1 / T1 signal interfaces and transmits the signals to the main exchange system; meanwhile, the slave exchange systems receive output signals of the main exchange system, divide the signals into at most 64 paths of E1 / T1 signals according to the information of channel numbers in the signals and send the E1 / T1 signal out. The invention can achieve the effects of simplifying the exchange control logic and design complexity configured by a user, shortening the data exchange delay, configuring a replacement 0-delay switching, not influencing the normal service and not losing data; the quantity adjustability of system interfaces is greatly increased, the usability is greatly improved, and the requirement for frequency jitter toleration of input data is wider.
