Embodiment 1

[0032] Such as figure 1 As shown, the service-driven transport network topology automatic design method described in this embodiment specifically includes the following steps:

[0033] Step 1: First build a fully connected network according to the business flow direction. The fully connected network is a full Mesh network, and the link capacity of the network is set to be infinite;

[0034] Step 1-1: Analyze the flow of business and obtain all nodes V that the business passes through i set V, query all nodes V at the same time i latitude and longitude; where: i=1, 2...|V|; |V| represents the number of nodes;

[0035] Step 1-2: Pull a network link L between every two points in V i , the link capacity is set to infinity, so as to obtain the topology G(V, L), where: i=1, 2...|L|, |L| indicates the number of link directions, and L is all links L i The set of nodes and links satisfy the following equation: |L|=|V|*(|V|-1) / 2;

[0036] Step 2: Set the target value σ of the avera...

Abstract

The invention discloses a method for automatically designing topology of a business-driven transmission network. The method includes firstly, building a fully connected network according to a business flow direction; secondly, setting a target value sigma of an average link utilization rate of the total network and a direction link utilization rate threshold sigma 0; thirdly, setting a variable n and setting the maximum planning frequency N; fourthly, obtaining bandwidth capacity Wi of each network link; fifthly, computing the quantity m of the links in each direction; sixthly, computing utilization rates of the links in various directions; seventhly, analyzing the utilization rates of all the links in topology G(V, L); eighthly, further deleting links in relevant directions if judgment for a result obtained in the seventh step is negative; and ninthly, computing an average utilization rate eta of the total network if the judgment for the result obtained in the seventh step is positive. By the aid of the method, the problem that topology of a network difficultly matches with a business flow direction in the prior art can be effectively solved, pertinence of network building and resource utilization rate are improved, provision and scheduling of later business are facilitated, and engineering investment is protected.

Description

technical field [0001] The invention relates to a communication transmission network, in particular to a service-driven transmission network topology automatic design method. Background technique [0002] Network construction often requires good security, reliability and scalability, while taking into account the principles of economy and efficiency, and strives to build a network based on the current situation and focused on the future. However, there is no corresponding specification or principle to guide the network construction method. The construction of the network topology is often based on the underlying optical cable network. The high requirements of construction cannot guarantee the quality of network construction. [0003] With the popularization of network services and products and the intensification of competition in the communication industry, the network construction of major operators pays more and more attention to the input-output ratio of business. This...
