Embodiment 1

[0022] figure 1 It is a flow chart of the method for planning the capacity of the packet transport bearer network provided by Embodiment 1 of the present invention. The technical solution of this embodiment can be performed by a device composed of hardware and / or software, and it is specifically applicable to a packet transmission bearer network with an established node topology, and a service flow sample is selected to plan the packet transmission bearer network Capacity configuration, specifically, the bandwidth of links between nodes can be configured so that it can meet the transmission requirements of service flow samples. There are various ways to obtain service flow samples. It can be extracted from historical service flow data for a period of time, or a service flow sample can be virtually set according to future network deployment requirements for network capacity planning.

[0023] Based on the above planned target network, the method of this embodiment performs the...

Embodiment 2

[0044]Embodiment 2 of the present invention provides a method for capacity planning of a packet transport bearer network. Based on Embodiment 1, the method is described in detail through an example. This embodiment takes figure 2 The network topology shown is taken as an example for illustration. Assume that the packet transmission bearer network includes five nodes A-E, and its connection structure is as follows: figure 2 shown. Business flow samples such as image 3 As shown, it includes three services, the service S_A-B from node A to node B, the service S_A-C from node A to node C, and the service S_C_B from node C to node B, and the service attributes are as follows:

[0045] Service S_A-B: CIR=1, EIR=4, using network protection;

[0046] Service S_A-C: CIR=2, EIR=0, using network protection;

[0047] Service S_B-C: CIR=0, EIR=4, network protection is adopted.

[0048] The values ​​of the above CIR and EIR represent bandwidth, and the unit may be Mbit / s. The follow...

Embodiment 3

[0097] Figure 4 It is a schematic structural diagram of the device for planning the capacity of the packet transport bearer network provided by Embodiment 3 of the present invention. The device can be implemented in the form of hardware and / or software, and is used to implement the method for planning the capacity of the packet transport bearer network provided by the embodiment of the present invention. The device specifically includes a route determination module 410 , a sub-capacity determination module 420 , a link capacity planning module 430 and a total capacity determination module 440 . Wherein, the route determination module 410 is used to determine the service route of each service respectively according to the route selection rules; the sub-capacity determination module 420 is used to determine the service commitment bandwidth of each link for each link involved in the service route Capacity, business extra bandwidth capacity and network protection and recovery cap...

Abstract

The invention provides a method and a device for planning packet transmission bearer network capacity. The method comprises the following steps of: respectively determining the service routing of each service according to routing selection rules; aiming at the links related to the service routing, respectively determining the service guaranteed bandwidth capacity, the service additional bandwidth capacity and the network protection and recovery capacity of each link; calculating the sum of the service guaranteed bandwidth capacity, the service additional bandwidth capacity and the network protection and recovery capacity, and taking the sum as the planned capacity of each link; and determining the configuration of the network capacity according to the planned capacity of each link. According to the method and the device for planning the packet transmission bearer network capacity, the requirements of different service flow models can be fully taken into account because the quantitative design is carried out on the levels of the links and the demands of service guaranteed bandwidth, service additional bandwidth and protection and recovery are given attention to. Furthermore, a statistical multiplexing manner is adopted, and the demands of the models of the service guaranteed bandwidth, the service additional bandwidth and the protection and recovery, are met as much as possible on the premise that less network capacity is configured, so that the reliability in service transmission is improved.

Description

technical field [0001] The invention relates to communication network technology, in particular to a method and device for capacity planning of a packet transmission bearer network. Background technique [0002] For existing optical fiber communication networks, especially packet transport bearer networks, network capacity planning and design are usually required. [0003] Packet transmission bearer network capacity planning and design refers to a series of technical means and methods to determine the network topology, equipment configuration, trunk bandwidth and service arrangement of the packet transmission bearer network, so that it can meet the given business needs, And meet the constraints of reasonable construction cost, feasible project implementation and convenient operation and maintenance. [0004] One of the core issues in the planning and design of the packet transmission bearer network is to plan the network capacity according to the service requirements and st...
