Embodiment Construction
[0087] This experiment is solved by commercial mathematical software GAMS / CPLEX, and the experimental parameters are set as follows:
[0088] ●Network topology and business requirements. Since the MILP problem is NP-hard, the experiment uses a multi-layer network with 6 nodes and 16 directed links (such as figure 1 shown). The business requirement d(ii, jj) of each node pair (ii, jj) is [0, 2D avg ] Random values uniformly distributed in the interval, whose mean is D avg , the adjustment parameter D avg The value of the value is 10Gbps, 20Gbps, ..., 100Gbps, which can meet the business requirements of different sizes.
[0089] ● IP layer parameters. The IP layer equipment is based on the specifications of the Cisco CRS3-4 / S router. The maximum power consumption is 3080W, the forwarding capacity is 560Gbps, and the power consumption of the frame is 696W. Each frame can accommodate 4 line cards. The power consumption of the card is 446W. There are 3 types of line cards:...

The invention discloses a multilayer network energy consumption optimization method facing IP over TDM over DWDM. The method is characterized by: firstly, defining an object function of IP over TDM over DWDM multilayer network power consumption; then providing constraint conditions of the object function on an IP layer, a TDM layer and a light layer; finally verifying the method by using an experiment from three aspects of a relation between a network layer and a multilayer network power consumption, the relation between dynamic power consumption and network power consumption and the relation between a modularization design and the network power consumption. An experiment result shows that the multilayer network energy consumption optimization method facing IP over TDM over DWDM is effective. The network power consumption can reduce as decrease of a service demand. When the service demand is in a low cycle (Davg=10Gbps), the network power consumption can decrease to 24%-38% of the power consumption when the service demand is in peak time (Davg=100Gbps). No matter how the dynamic power consumption and the modularization structure of network equipment changes, a conclusion that the network power consumption reduces as the decrease of the service demand always keeps consistent.
Description
Technical field [0001] The invention relates to the technical field of network energy consumption optimization, in particular to an IP over TDM over DWDM-oriented multi-layer network energy consumption optimization method. Background technique [0002] In the context of the current global advocacy of "low-carbon economy", energy conservation and emission reduction has become an important responsibility of governments of all countries. As one of the fastest growing industries in the world, the ICT industry has also been increasing its carbon emissions. According to Gartner's 2007 report titled "Green IT: The New Wave of Industry Impact", the annual carbon emissions of computer and telecommunication equipment account for about 2% of the total global carbon emissions, and this proportion will increase by 2020. Doubled, energy saving and emission reduction has become an urgent issue that the ICT field must face. With the rapid development of the Internet, services such as vide...
