摘要： The present invention discloses a method, routing bridge, and system for sending a packet, which are applied to the field of communications technologies, and are invented to reduce a signaling overhead of a TRILL network. The method includes: receiving, by a first transit RB, a Nickname of an edge RB sent by a second transit RB; constructing, an address advertisement message, where the address advertisement message includes a virtual IP address and a virtual MAC address of the first transit RB; and sending, the address advertisement message to the edge RB according to the Nickname of the edge RB, so that the edge RB sends, after receiving the address advertisement message, a free ARP packet to a server that accesses the TRILL network through the edge RB, where the free ARP packet includes a correspondence between the virtual MAC address and the virtual IP address.

摘要： Embodiments of this application provide a method and an apparatus for determining virtual machine VM migration. The method includes: after a VM is migrated, sending a gratuitous ARP packet or a RARP packet to an in-migration VTEP device; obtaining, by the VTEP device, a MAC address of the VM, searching an ARP cache table based on the MAC address, and obtaining an IP address of the VM; and constructing an ARP unicast request packet by using the IP address as a destination IP address, and if the VTEP device receives an ARP response packet sent by the VM for the ARP unicast request packet, determining that the VM is migrated.

摘要： The present invention provides a method and an apparatus for detecting a synchronization position of an LTE cell. A part of sampling points are selected from all sampling points of received data, where the received data is generated by filtering a local sequence from a base station; correlation operations are carried out on the part of the sampling points, and multiple first correlation results and multiple pieces of first position information that correspond to the part of the sampling points are obtained; and a maximum first correlation result is determined among at least one first correlation result greater than a preset threshold in the multiple first correlation results, and a piece of first position information, which corresponds to the maximum first correlation result, is taken as a synchronization position.
