A method for managing traffic item in software defined networking includes establishing a downlink flow table of a switch according to the flow entries, establishing an uplink flow table of the switch according to the flow entries, acquiring a data packet by the switch, and generating a transmission path to allocate the data packet according to the data packet, the downlink flow table, and the uplink flow table. The downlink flow table includes a correlation between first transmission ports of the switch and down link switches. The uplink flow table includes a correlation between the first transmission ports and a transmission port group of uplink switches.

Method for managing traffic item in software-defined networking

A network system and a routing method are disclosed herein. The routing method includes receiving a route planning request corresponding to a packet flow; calculating a corresponding value according to the route planning request; comparing the corresponding value with a plurality of matching values stored in a storage space; and under a condition that the corresponding value matches a corresponding one of the matching values, acquiring an assigning path stored in the storage and routing the packet flow along the assigning path.

Network system and routing method

The load balancing method includes: receiving identify information of the nodes to construct a network topology diagram and receiving support rates of connection ports through a controller; monitoring average data rates of the connection ports through the controller; when the average data rate of one of the connection ports is in excess of a congestion criteria, searching a packet flow with the highest data rate among packet flows passing through the connection port of which the average data rate is in excess of the congestion criteria through the controller; and performing a shortest path first algorithm according to the packet flow with the highest data rate and the network topology diagram, wherein the computed connection ports do not include the connection port of which the average data rate is in excess of the congestion criteria; and a new transmitting path is acquired.

Network system and load balancing method

A network communication system comprises a cloud network and at least one physical machine. The cloud network comprises at least one physical switch. Each the physical machine comprises a plurality of virtual machines and a virtual switch. Each of the virtual machines is connected to the at least one physical switch in the cloud network through the virtual switch. The virtual switch encapsulates a destination machine address of an egress frame sent by the virtual machines, attaches a destination switch address to the egress frame to be forwarded to the at least one physical switch, and receives and analyzes an ingress frame obtained from the at least one physical switch, so as to convert the destination switch address of the ingress frame to the destination machine address, for forwarding the ingress frame to one of the virtual machines.

Network communication system and network communication method

The routing method includes: receiving identification information of nodes to construct a network topology diagram and receiving support rates of connection ports through a controller; monitoring data rates of the connection ports through the controller; receiving a route planning request through the controller; separately calculating costs of links according to the data rates of the connection ports and the support rates of the connection ports after receiving the route planning request through the controller; searching a plurality of candidate paths between a source-destination pair according to the route planning request and the network topology diagram through the controller; summing the costs of links passed by each candidate path to acquire a sum of link-cost of each candidate path through the controller; and, selecting one of the candidate paths with the smallest sum of link-cost as a packet transmitting path between the source-destination pair through the controller.
