Embodiment Construction

[0047] figure 1 It is a schematic diagram of the network architecture based on NFV. Such as figure 1 As shown, the network architecture mainly includes left and right parts, specifically,

[0048]The left side includes from bottom to top: hardware resource layer, virtualization layer, virtual resource layer, network element layer, and Operational Support System (OSS for short) / Business Support System (BSS for short). Among them, the hardware resources (Hardwareresources) layer can include: computing hardware, storage hardware, network hardware, etc.; the virtual resource layer can include: virtual computing resources, virtual storage resources, virtual network resources, etc.; hardware resource layer, virtualization layer and virtual resources Together, the layers make up the Network Functions Virtualization Infrastructure (NFVI). The network element layer may include: various virtual network functions (Virtual Network Function, VNF for short), and each VNF may have its own...

Abstract

The invention provides a method and device for flexibly processing a link between network elements. The method comprises the following steps that: a first network element detects a link load parameter of the first network element; when the link load parameter of the first network element satisfies a pre-set condition, the first network element sends a flexible link change request to a second network element on a first link and negotiates with the second network element so as to flexibly change a link between the first network element and the second network; and the first network element receives a flexible link change response sent by the second network element on the first link and initiates a flexible link change operation request to the second network element according to the flexible link change response, such that flexible link change between the first network element and the second network element is completed. The flexible link change between the first network element and the second network element is realized; therefore, the link between the network elements can be flexibly changed according to practical requirements; and lack or waste of link resources due to resource change of network elements can be avoided.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and device for elastically processing links between network elements. Background technique [0002] The traditional network of network operators is deployed through large-scale and continuously growing dedicated hardware devices. Specifically, the network of network operators is a very complex network composed of a large number of network elements. The communication between network elements is generally carried over the link. The introduction of a new network service usually requires major adjustments to the hardware deployment and bearing capacity of the entire network. Add to this the increasing power consumption, capital investment challenges, and lack of necessary skills to design, integrate, and operate increasingly complex hardware devices. Therefore, the operator alliance proposed Network Function Virtualization (Network Function Virtualization, referred to as...
