Embodiment Construction

[0047] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0048] The present invention adopts the first model idea---a deactivation model, and proposes an energy-saving traffic scheduling mechanism oriented to hybrid SDN networks in combination with SND technology.

[0049] The ESTS mechanism sets the hybrid SDN network as G(N, L), where N represents the set of nodes in the network, and L represents the set of all directed physical links in the network. The set of link weights is denoted as W, and the initial weight of all links is set to 1. The traffic demand from any node k to other network nodes t(k,t∈N) is expressed as h kt , the capacity utilization of any link l(l∈L) is expressed as μ, when μ is greater than a specified threshold α, the remaining capacity of the link is 0, that is, α is the maxim...

Abstract

The invention discloses a hybrid SDN network-oriented energy-saving flow scheduling method. On the premise of satisfying a flow forwarding demand, a link weight is adjusted according to the link capacity utilization rate in an IP (Internet Protocol) network, therefore, and when the capacity utilization rate of a certain link is low, the link is closed, thereby avoiding the waste of energy, and conforming to the concept of a green energy-saving network; and meanwhile, in combination with a flow dynamic allocation function of an SDN switch, the hybrid SDN network-oriented energy-saving flow scheduling method provided by the invention solves the problem of an energy-saving flow scheduling mechanism of the hybrid SDN network.

Description

technical field [0001] The invention belongs to the field of network flow engineering, and in particular relates to a flow scheduling mechanism capable of effectively saving energy in an SDN / IP hybrid network. Background technique [0002] With the expansion of network scale and the continuous enrichment of network equipment functions, the current network is increasingly exposed to many problems such as high energy consumption, low efficiency, and excessive waste. Saving network energy consumption and building a green network has not only become a significant and urgent issue in the computer field, but also an important factor affecting the sustainable development of society and ecology. It is an important issue to reduce network energy consumption through an energy-saving traffic scheduling strategy. [0003] Considering the rapid development and broad application prospects of SDN, energy-saving traffic scheduling strategies must be combined with SDN scenarios. SDN is a t...
