Embodiment Construction

[0190] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0191] The term "multi-domain network" means a network comprising at least two network domains.

[0192] The term "adjacent domain" means a network domain that is adjacently connected to a network domain.

[0193] The term "UNI" indicates the interface through which users access the network domain, and is the dividing point between users and the network domain.

[0194] The term "external network to network interface (External Network to Network Interface, ENNI)" indicat...

Abstract

The embodiment of the invention discloses a network-as-a-service business cross-domain collaboration method, collaboration equipment and control equipment, which are used to realize end-to-end NaaS services in a multi-domain network composed of multiple network domains. The method in this embodiment of the present invention includes: acquiring information about the first UNI and information about the second UNI in the multi-domain network according to the received NaaS service request, where the NaaS service request is used to request the establishment of an NaaS service request between the first terminal and the second terminal NaaS service, query domain resource information, obtain the cross-domain path between the first UNI and the second UNI, determine the network domain that the cross-domain path passes through, and obtain the network domains in the network domain that the cross-domain path passes through The first connection requirement and the second connection requirement of the domain, and then send the first connection requirement and the second connection requirement to the control device of each network domain.

Description

technical field [0001] The present invention relates to the field of communication, and in particular to a network-as-a-service business cross-domain collaboration method, collaboration equipment and control equipment. Background technique [0002] With the continuous development of new technologies for network equipment, Software Defined Network (SDN) has become a hot spot, and Openflow is a typical structure of SDN. There are two types of devices in an Openflow network: controllers and Openflow switches. The control device is responsible for centralized control of the network and sends flow tables to the Openflow switch. At the same time, the control device is open to users, and the Openflow switch performs packet matching and forwarding according to the flow table. [0003] It can be seen that network devices are shifting towards a centralized control architecture with separated control and forwarding, and consequently, the network architecture has also changed. This arc...
