摘要： A method includes a first provider edge (PE) device sending, to a second PE device, a media access control (MAC) route learned from a customer edge (CE) device and a virtual local area network (VLAN) identifier, wherein the second PE device generates a MAC forwarding entry based on the MAC route and the VLAN identifier, where the MAC forwarding entry is used to directly forward, using the CE device, a packet whose destination MAC address is the CE device or a MAC address of a terminal device accessing the CE device. An outbound interface identifier included in the MAC forwarding entry is an identifier of an interface connected to the CE device.

摘要： The method includes the following steps: The second PE device sends, to the first PE device, a MAC route learned from the CE device. The first PE device generates a MAC forwarding entry based on the MAC route. The first PE device may forward, based on the MAC forwarding entry by using the CE device, a packet whose destination MAC address is the CE device or a MAC address of a terminal device accessing the CE device. An outbound interface identifier included in the MAC forwarding entry is an identifier of an interface connected to the CE device. According to the method in this application, load can be effectively shared between the second PE device and the first PE device, and system bandwidth resources can be properly used.

摘要： A co-channel interference cancellation method and apparatus are provided. The method includes: obtaining effective interference by filtering co-channel interference according to a preset interference strength threshold, and obtaining a plurality of effective interference subgroups by grouping the effective interference; obtaining a reference interference sub-signal corresponding to the effective interference subgroup, by delaying a reference interference signal according to a determined interference delay of each effective interference subgroup; after each reference interference sub-signal passes through a corresponding adaptive interference reconstruction filter, obtaining a reconstructed interference signal by overlaying each reference interference sub-signal; and performing a subtraction operation on a received signal and the reconstructed interference signal. In this way, spectrum consumption is greatly reduced, and implementation is simple.

摘要： The present disclosure provides a symbol synchronization method and apparatus. By means of the symbol synchronization method and apparatus, a timing location is adjusted outside an adaptive loop. In addition, the adaptive loop proceeds to according to an original function of the adaptive loop. That is, the timing location is stabilized to an initial symbol-synchronization location, and the timing location is then further corrected and adjusted. Therefore, impact of an error of a timing location on symbol synchronization is eliminated by correcting the timing location, and positioning accuracy of a symbol-synchronization location is improved.
