Bandwidth capping is implemented at a logical port level for a shared Ethernet port. When a physical port of a Host Ethernet Adapter (HEA) is partitioned, a Logical HEA is created for the partition. One or a plurality of Logical Ports (LPorts) is created in the Logical HEA. Each LPort is mapped to a corresponding physical port. During LPAR configuration, a minimum guaranteed speed is specified forthe LPort together with the corresponding physical port for the LPort and an optional maximum speed. The specified configuration for the LPort is verified, and the configuration values are stored inthe HEA and the HEA dispatches data packets based upon the stored configuration values for the LPort.

A SDN controller firstly creates a plurality of vtep ports in network equipment switch in a mode of issuingan instruction, uses the vtep points as tunnel ''endpoints'', i.e., ''accesses'' of tunnels, which are used for network data to pass through, designates an IP address to tunnel opposite-end equipment, and finally, sets a bandwidth upper limit of each port according to a message parameter; and after creation of the tunnels is completed, the SDN controller issues an OpenFlow flow table to the network equipment to control a network data packet forwarding behavior. The SDN network multichannel line bandwidth dynamic allocation method sufficiently utilizes a line bandwidth and is automatic in bandwidth allocation; channels with different bandwidth sizes are used for different services to use; and service quality, flexibility and efficiency of the integral network are improved.

The invention discloses a traffic routing method, a router and a communication system. In the embodiment of the invention, a dynamic traffic information base is established by collecting data traffic information of links in a network, thus determining the load condition of a current link; and then routing is made according to the load condition of the current link, that is, part of the data traffic of the current link is switched to a light-loaded standby link which is currently invalid to perform transmission if the load is judged to exceed a maximum bandwidth upper threshold K of the current link, thus avoiding the problem of packet loss caused by that the current link directly discards the part of the data traffic which exceeds the bandwidth when the links are congested, effectively protecting user data, allocating bandwidth more reasonably and improving the utilization ratio of the bandwidth.

A service platform for a content delivery network indicates a transmission rate cap to be imposed when streaming data to a data requesting device over an access network. Means are provided for receiving a service request for delivery of data from a requesting device as the result of which the requested data is delivered as a prioritised traffic stream over an access link to the requesting device. The service platform processes the service request to determine one or more performance characteristics of said access link and uses this to determine the maximum transmission rate for the requested data to be streamed at over the access link during its delivery to the requesting device. This information is included in a source address for the requested data which the service platform generates, typically as a URL. The maximum transmission rate set is provided as a prefix to the URL (or in some other meta-data format) to the requesting device, and the content delivery platform is configured to ensure that requests for media assets which are received at the logical or virtual ports associated with the URL pre-fixes are responded to by transmissions limited to the maximum bandwidth cap indicated by the URL pre-fix.
