Resource management method and device

Abstract

The embodiments of the present invention provide a resource management method and device. The method comprises that a resource management device obtains status parameters of a plurality of VNFs comprised by an E2E network; according to the status parameters, a first to-be-expanded VNF and a first resource capacity required for expansion are determined in the plurality of VNFs; if idle resource capacity in a resource pool is smaller than the first resource capacity, then according to the status parameters, the resource management device determines a first to-be-compressed VNF in the plurality of VNFs, and compresses the first to-be-compressed VNF according to the first resource capacity; and if the idle resource capacity in the resource pool is larger than or equal to the first resource capacity after the resource management device compresses the first to-be-compressed VNF, the resource management device expands the first to-be-expanded VNF. By means of the embodiments of the present invention, a balanced allocation of resources among VNFs in the E2E network is ensured under conditions of insufficient idle resources, and thus, resource utilization and the service success rate of the E2E network are improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource management method and device. Background technique [0002] The traditional telecommunication network is composed of a variety of physical devices. Different network services require different physical devices. With the rapid growth of the network scale, the telecommunication network becomes more and more large and complex, which also brings many problems. For example, the development and launch of new services is relatively slow, the operation and maintenance of the system is complex and costly, and the resource utilization rate is low. [0003] The proposal of Network Function Virtualization (English: Network Function Virtualization, abbreviation: NFV) technology can solve the above problems very well. NFV technology can be understood as migrating the functions of each network element used in the telecommunication network system from the current dedi...

Problems solved by technology

[0004] For the end-to-end (English: End To End, abbreviation: E2E) network using NFV technology, compared with the overload flow control of the front-end network elements, the overload flow control of the back-end network elements will cause more waste of network resources. The business success rate is low; while the front-end network elements are overloaded with flow control and the back-end network elements are lightly loaded, the service success rate of the E2E network cannot be maximized because the network element resources with light loads are not fully utilized

Although the service success rate of the E2E network can be improved by directly expanding the capacity of network elements with overload flow control, this requires sufficient idle resources in the resource pool, and the resource utilization rate at this time is not high
