One embodiment of the present invention provides a switch. The switch includes a port that couples to a server hosting a number of virtual machines. The switch also includes a set of virtual port grouping information and a virtual port grouping mechanism. During operation, the virtual port grouping mechanism determines whether a frame is traveling from a virtual port group to the same virtual port group. If the frame is not traveling to the same virtual port group, the virtual port grouping mechanism prevents the frame from being forwarded.

One embodiment of the present invention provides a system that performs layer 3 (L3) aware switching in an Ethernet passive optical network (EPON) which includes a central node and at least one remote node. During operation, the system maintains a set of mapping information which indicates a correspondence relationship between a logical link identifier of a remote node, a medium access control (MAC) address for a subscriber coupled to the remote node, and an IP address for the subscriber. Upon receiving a packet which contains an IP address, the system selectively attaches a proper logical link identifier to the packet based on the mapping information and the IP address contained in the packet, thereby allowing only one proper remote node to receive the packet.

The invention discloses a traffic flow control method of a switch service flow, comprising: monitoring the instant value of the total flow of the service flow at the outlet port of the switch; judging whether the total flow of the service flow is congested according to the instant value of the total flow of the service flow; The judgment result adjusts the flow rate limit value of the service flow at the ingress port of the switch according to the weight ratio of the service flow, so as to realize flow control on the service flow. The invention also discloses a flow control device for exchange service flow. By applying the present invention, when the flow rate of the high-priority service flow is low, the flow rate limit value of each service flow at the ingress port of the switch can be dynamically adjusted, and the remaining bandwidth of the high-priority service flow can be used to provide additional bandwidth for other service flows. Bandwidth, which effectively utilizes the bandwidth resources in the switch; and because the flow of each service flow is limited at the ingress port, the forwarding channel when forwarding across chips and the backplane bandwidth when forwarding across service boards are saved.

The invention discloses a connectivity sensing routing method on the basis of location prediction in a vehicle ad hoc network. By the connectivity sensing routing method, the problem that the connectivity of routes cannot be guaranteed when the optimal routes are determined in the prior art is solved. The connectivity sensing routing method includes particular steps of firstly, finding required routes for arriving at a destination node by a region flooding process; secondly, taking forwarding time delays of data packets on the routes with certain connectivity probabilities into consideration and selecting the route with a large connectivity probability and the shortest time delay as the optimal route; thirdly, forwarding the data packets according to a process on the basis of location prediction.
