The invention discloses an SDN (Software Defined Networking) enhanced path encasement device and method, which are used for solving the encasement problem appearing in an SDN controller-based path computing unit. According to the invention, bandwidth resources in the communication network are comprehensively considered; The invention discloses an SDN controller network topology planning method based on particle swarm optimization, relates to related constraint conditions such as disturbance and time delay, combines a particle swarm algorithm with an SDN controller network topology planning module related technology, aims at intelligently adjusting service path planning under the condition that new service bandwidth resources in a network are insufficient, and provides a boxing scheme, andbelongs to the field of telecommunication network intelligent algorithm optimization. The main innovation points are as follows: 1, a network boxing service arrangement scheme based on an SDN technology; 2, SDN-based network service scheduling is introduced into the encasement decision model; And 3, improving the overall bandwidth utilization rate of the network by using a particle swarm algorithmmodel.

Description

technical field [0001] The invention belongs to the field of intelligent algorithm optimization of telecommunication networks, and in particular relates to an SDN enhanced path packing device and method. Background technique [0002] In the current communication network environment, bandwidth resources are the most critical resources in the network. When the network load is unbalanced, that is, the bandwidth utilization rate of some parts of the network is too high, while the bandwidth utilization rate of the rest of the network is too low, it will cause unnecessary network congestion and waste of resources, and it will occur when the current overall network bandwidth resources are sufficient The legal path cannot be calculated for the newly added service. In order to realize the reasonable utilization of network resources, some intelligent algorithms can be used to adjust the distribution of network resource usage, and calculate the optimal path allocation scheme, that is,...
