摘要： The present invention relates to a bidirectional forwarding detection BFD session negotiation method, device, and system. The bidirectional forwarding detection BFD session negotiation method includes: generating a first discriminator value, where the first discriminator value is unique in a local area network to which a local device belongs; generating a first BFD control packet, where the first BFD control packet includes the first discriminator value; and sending the first BFD control packet to a peer device, so that the peer device performs a session negotiation with the local device according to the first discriminator value. A local discriminator value is set as a unique value in a local area network to which a local device belongs, so as to eliminate the possibility that different BFD sessions in the local area network generate a same MD. This eliminates a session negotiation error incurred by an error configuration or miscellaneous packet deception, thereby improving efficiency and security of a BFD session negotiation.

摘要： A method for implementing backup of the uplink includes the steps of: A. more than one uplinks are configured for the internet group multicast protocol (IGMP) proxy device, and one of them is the main uplink; B. The IGMP proxy device only copies the multicast data message received from the main uplink to the downlink which connects it to the multicast user. By using and applying the method of the present invention, only the main uplink is used, therefore the waste of the multicast user link bandwidth is reduced and the multicast data transmission rate is increased. During the process of detecting the usability of the main uplink, flexible detection mode could be used, thus the IGMP proxy device could rather discover the usability of the main uplink real-time, therefore, the main uplink could be reselected on time and the normal multicast communication could be ensured.

摘要： This application discloses an optical receiver, including an optoelectronic detector, a transimpedance amplification circuit, a single-ended-to-differential converter, an I/O interface, and a controller. The optoelectronic detector is configured to convert a received optical signal into a current signal, where bandwidth of the optoelectronic detector is lower than a system transmission bandwidth requirement. The transimpedance amplification circuit is configured to: receive the current signal and a first control signal, and perform transimpedance gain on the current signal based on the first control signal, to obtain a voltage signal, where a frequency response value of the current signal within first bandwidth is greater than that within the bandwidth of the optoelectronic detector, and any frequency in the first bandwidth is not lower than an upper cut-off frequency of the optoelectronic detector. The single-ended-to-differential converter is configured to convert the voltage signal into a differential voltage signal. The I/O interface is configured to output the differential voltage signal. The controller is configured to generate, based on the differential voltage signal, a second control signal that is used to control the transimpedance amplification circuit to perform transimpedance gain on the current signal. According to the optical receiver disclosed in this application, costs are reduced while received signal quality is ensured.
