One embodiment discloses a method and apparatus for synchronizing IP information of virtual machines. The method includes: obtaining an IP relevant message of at least one virtual machine within a subnet, recording IP information and connection information of the at least one virtual machine based on the IP relevant message, and modifying connection information of a specific virtual machine in response to migration of the specific virtual machine. The apparatus corresponds to the method. With the method and apparatus above, IP information and connection information of respective virtual machines within the subnet are recorded regularly and routinely. Once a certain virtual machine is migrated, updating and modifying connection information of the migrated virtual machine is only needed, but without a need for resending a request to the Dynamic Host Configuration Protocol (DHCP) server. Thus, network disruptions caused by non-synchronization of IP information when the virtual machine is migrated are avoided.

Embodiments of the invention relate to reflective relay (RR) processing on logical ports for channelized links in edge virtual bridging (EVB) systems. One embodiment includes providing a virtual edge bridge (VEB) mode and a virtual Ethernet port aggregator (VEPA) mode in an EVB system on a same port of a physical switch. RR capability per channel is negotiated between a server and the physical switch in the EVB system. RR per channel is supported on the physical switch of the EVB system using RR setting information per channel.

A method of managing data transmission based on virtual local area networks includes obtaining a first VLAN property of a first physical interface and a second VLAN property of a second physical interface; in response to determining the first VLAN property and the second VLAN property are at least partially identical, obtaining a first virtual interface corresponding to the first physical interface and a second virtual interface corresponding to the second physical interface; and mapping the first physical interface and the second physical interface to an identical data channel via the first virtual interface and the second virtual interface, wherein the first physical interface and the second physical interface are located in a same processing device.
