The invention discloses a system and a method for inhibiting paths, wherein the method comprises following steps: numbering the frequency of oscillations which take place on an optimum path which reaches to an objective net path, inhibiting the optimum path by an inhabitation execution unit under the condition that statistical results of a frequency statistic unit reach to an inhabitation threshold. The invention can prevent the condition that the optimum path and a suboptimum path are inhibited simultaneously due to the oscillations of the optimum path from happening and thereby the invention is more suitable in an IP network which is deployed with rapid convergence strategies.

The invention discloses a multicasting stream forwarding method, device and system. Aiming at the condition that a VC (Video Client) and a video EC (encoder) are in the same network segment, a VM (Video Management) server can establish a channel from the EC to the VC through informing the EC of carrying out a dynamic multicasting VLAN (Virtual Local Area Network) declaration and informing the VC of carrying out a dynamic multicasting VLAN declaration, a multicasting stream can be forwarded to the VC from a multicasting source along the channel, thus unnecessary multicasting flood is avoided, and the occupied bandwidth resources are reduced. Aiming at the condition that the VC and the EC are not in the same network segment, the VM server can establish a channel from the EC to a gateway router and then from the gateway router to the VC through informing the EC of carrying out the dynamic multicasting VLAN declaration and informing the gateway router of carrying out the dynamic multicasting VLAN declaration, the multicasting stream can be forwarded to the VC from the multicasting source, thus unnecessary multicasting flood is avoided and the occupied bandwidth resources are reduced.

The invention discloses a data transferring system and a data transferring method of an intelligent metering device. The data transferring system comprises a plurality of intelligent metering devices, power supplies embedded in all the intelligent metering devices, a data acquisition module, a data transmission module, wireless terminal equipment adaptive to the intelligent metering devices in the same area, and a remote monitoring host, wherein the power supplies supply power to the data acquisition module and the data transmission module, the data acquisition module acquires data of the intelligent metering devices, the data transmission module can transmit the data to the wireless terminal equipment wirelessly in a close range, and the wireless terminal equipment transmits the data to the remote monitoring host in a master control room wirelessly and remotely, and the remote monitoring host is used for recording and processing data. The data transferring method comprises the steps of presetting the meter reading time by the data transmission module, acquiring data of all meters in the same network segment in a time-phased manner by the data acquisition module, and transmitting the data to the wireless terminal equipment by the data transmission module in a close range, and remotely transmitting the data to the monitoring host wirelessly by the wireless terminal equipment for recording and processing. The data transferring system and the data transferring method are applied to the field of intelligent metering devices.

The invention discloses a method for acquiring information of equipment hung under a gateway. The method is applied to a first gateway. A hanging device is hung below the first gateway. The first gateway is bridged to a second gateway. The method comprises the steps that the hanging device communicates with a second gateway through a DHCP protocol to obtain a first IP address; the hanging device broadcasts a DHCP selection message after selecting the first IP address provided by the second gateway, including starting a DHCP monitoring process on the first gateway to monitor the DHCP selectionmessage; based on the DHCP selection message, obtaining the first device information of the hanging device, wherein the first device information comprises the first IP address; based on the second IPaddress and the first IP address, sending an ARP request packet to the hanging device, wherein the second IP address is an IP address obtained by a second DHCP client in the first gateway from the second gateway, and the second IP address and the first IP address are located in the same network segment; and when an ARP response packet fed back by the hanging device is received, determining that the hanging device is in an online state and the first device information is valid.
