Problems solved by technology

Since an end-to-end service spans the access network, metropolitan area, IPcore domain, etc., there will be scenarios where multiple technologies and multiple domains coexist. For example, an end-to-end service includes a pure virtual local area network (Virtual Local Area Network, VLAN) technology, L2VPN in the metropolitan area and L3VPN in the IPCore domain, L3SM and L2SM defects make it impossible to adjust QoS in a unified way for end-to-end services

Embodiment Construction

[0084] This application provides a cross-domain QoS adjustment method. The method of this embodiment is applied in a cross-domain scenario. In a cross-domain scenario, an end-to-end service usually passes through multiple different domains, and multiple different domains may be located in different countries, State or city, and multiple domains may use different technologies. figure 1 It is a schematic diagram of cross-domain enterprise interconnection, such as figure 1 As shown, the cross-domain enterprise has four branches in total: branch 1, branch 2, branch 3, and branch 4, and each branch is a subsidiary or service point. The 4 branches can be located in different countries, provinces or cities, etc., and the 4 branches can communicate with each other by purchasing a cross-domain combined VPN. A combined VPN refers to a VPN composed of multiple associated segmented VPNs. Each branch A segment VPN corresponds to a domain, and a segment VPN is also called a segment VPN.

Abstract

The invention provides a cross-domain QoS adjustment method and device. The method comprises the following steps: enabling a coordinator to receive a name and a target bandwidth of a target cross-domain QoS adjustment strategy template of a service; determining a single-domain QoS configuration of a domain corresponding to a segmented VPN included in the service access path from at least one cross-domain QoS adjustment strategy template corresponding to a pre-obtained service type strategy template of the service according to the name and target bandwidth of the target cross-domain QoS adjustment strategy template of the service and a domain corresponding to a segmented VPN included in the service access path, and sending the single-domain QoS configuration to a corresponding controller, wherein each cross-domain QoS adjustment strategy template comprising a single-domain QoS adjustment strategy of one bandwidth interval in at least one domain. Therefore, QoS adjustment is carried outon the end-to-end service in a unified and automatic mode under the scene that multiple technologies and multiple domains coexist.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a cross-domain Quality of Service (Quality of Service, QoS) adjustment method and device. Background technique [0002] With the rapid growth of network services and the rapid development of communication networks, users have higher requirements on the network, and users hope to obtain faster rates and lower delays. In the face of complex networks and user requirements, QoS has gradually become a key indicator for measuring network performance. QoS is a technology used to solve problems such as network delay and congestion. [0003] At present, the sales model of operators for network services is usually simplified as packages and bandwidth, but an end-to-end service usually passes through various domains (for example: access domain, metropolitan area and core (CORE) domain, etc.). Existing QoS adjustment methods for end-to-end virtual private network (Virtual Private...
