Embodiment 1

[0055] Taking a simplified DCI network as an example, its network structure is as follows Figure 5 As shown, the figure contains 3 DCs and a network topology. The DCs are maintained by the DC controller in the figure, and the network topology is controlled and managed by the SDN controller in the figure. DC1, DC2, and DC3 pass through NE1 respectively. , NE3 and NE4 access such as Figure 5 in the network shown.

[0056] Suppose there is a connection DC1-NE1-NE2-NE3-DC2 in the network, and the transmitted content is real-time signal X. At this time, when the SDN controller receives another request message, since the existing technology cannot support content expression, the SDN controller still needs to establish a new connection for the request no matter whether there is duplicate content in the network. However, this application introduces the content tag, which allows DC to add the requested content in the request information, so the SDN controller can extract the conten...

Embodiment 2

[0062] The embodiment of this application is still as follows Figure 5 The network structure shown is taken as an example, assuming that there is a connection DC1-NE1-NE2-NE3-DC2 in the network, and the real-time signal Y is transmitted. At this time, the SDN controller receives another request message from DC3, which is DC3 requesting the transmission of a certain service from DC1. Through the content label identification technology, the SDN controller knows that the content of the service requested by the request message is a real-time signal Y, and The service transferred by the existing connection is the same, you can try to share the existing connection; but the existing connection only partially overlaps with a connection in the network topology that meets the requirements of the requested information, so DC1-NE1-NE2-NE4-DC3 in the network topology It is the first connection. Obviously, the overlapping part of the existing connection and the first connection is DC1-NE1-...

Embodiment 3

[0064] Assuming that a simplified DCI network is still taken as an example, the network structure is still as Figure 5 As shown, the SDN controller receives two request messages at the same time, and the existing network structure already has connections for transferring certain services. At this point, comparing the content tags of the two request information, two situations will occur:

[0065] In the first case, if the source client device identifiers, sink client device identifiers, and content tags of the two request information match, the SDN controller will merge the two request information to obtain a network topology that satisfies the two request information, and further Compare the connection in the network topology with the existing connection in the network, if there is a connection in the network topology that is the same as the transfer service and overlaps with the existing connection in the network, the workflow is as shown in Embodiment 1; if In the network...

Abstract

The invention discloses a service scheduling method, which comprises the steps of receiving request information, and obtaining a source client equipment identifier, a destination client equipment identifier and a content label from the request information; obtaining a network topology satisfying the request information according to the source client equipment identifier and the destination clientequipment identifier; according to the network topology and the content label, judging whether a first connection exists in the network topology, wherein the first connection and an existing connection in a network have an overlapped part, and the service requested by the request information is the same as the service content transmitted by the existing connection; if the first connection exists,establishing second connection according to the part, not coinciding with the existing connection, of the first connection, and taking the coinciding part of the existing connection and the second connection as connection meeting the request information together; and sending out a message that the connection satisfying the request information is successfully established. According to the scheduling method disclosed by the invention, the existing connection in the network can be utilized, and the effect of improving the utilization efficiency of network resources is achieved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a service scheduling method and system based on a software-defined network (SDN). Background technique [0002] At this stage, the application of software-defined network (Software Defined Network, SDN) technology makes network control from distributed to centralized, the control plane of network equipment is simplified, and the control function is upgraded to a centralized controller, which can be used for network business distribution and configuration of network devices. In this network deployment, there is one controller and multiple network devices, that is, multiple network elements (Network Elements, NEs). The NE and the controller are connected through a standard interface (usually called the SDN southbound interface) to realize the controller's control over the NE; and the other end of the controller is usually connected to the network user, that is...
