Abstract

The invention provides a global service dynamic optimization method and device for a software defined packet transport network. Cyclic or triggered routing calculation and bandwidth allocation are performed by monitoring the global network resource state and the service bandwidth change in real time. The method comprises the steps of calculating routing via a routing algorithm, and allocating an initial minimum bandwidth to each service according to a minimum bandwidth parameter of each service; calculating the bandwidth allocated to each service in the remaining network resource according to the weight value of each service and the real-time monitored service bandwidth data, and performing remaining bandwidth allocation; and allocating a routing path to each service according to the initial minimum bandwidth allocated to each service and the bandwidth allocated to each service in the remaining network resource. The method and the device realize service routing allocation and dynamic optimization, and then realize load balance, thereby improving the utilization rate of resources and improving the user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a method and device for dynamically optimizing global services of a software-defined packet transport network. Background technique [0002] Software Defined Packet Transport Network (SPTN) is the integration and innovation of Software Defined Network (Software Defined Network, SDN) and Packet Transport Network (PTN), providing intelligent control plane technology for PTN network, It can realize flexible scheduling of network resources. It is used to solve the problems encountered in the service opening, operation and maintenance links caused by the large-scale deployment and application of the PTN network and the continuous improvement of the service quality and reliability requirements of various services. For example, in terms of PTN service provisioning, PTN networks of different manufacturers are managed by their own network management systems, cross...
