Problems solved by technology

[0006] At present, the MAN traffic forecasting method used by most operators is relatively simple, without distinguishing between users and business peak time periods, and often adopts the method of directly superimposing peak traffic. This method has poor accuracy and is difficult to meet the expansion requirements.

Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described by referring to the drawings.

[0024] figure 1 Taking the existing MAN of an operator as an example, it is a schematic diagram of the evolution process of the network to the crossover type and the full connection type.

[0025] At present, the core layer of the backbone network is connected to the egress routers of some unreformed urban area networks, which are mainly N*10G links, and the network structure is square, with weak security and reliability. At the same time, it is recommended that the network evolve to a cross-connected and fully-connected type. The evolution process is as follows: figure 1 shown. It includes the following evolution steps.

[0026] Evolution step 1: When expanding to four 40G / 100GE circuits, for the sake of network security and reliability, optimize the original point-to-point connection to a cross-connection, and each device at the egress of the MAN is connected to the ...

Abstract

The invention relates to a metropolitan area network planning method. The method comprises the following steps of: collecting metropolitan area network output peak flow, BRAS (Broadband Remote Access Server) peak flow, IPTV (Internet Protocol Television) peak flow and SR peak flow through a network manager of the metropolitan area network, and calculating to obtain metropolitan area network exit proportion of each local area network; calculating the metropolitan area network output peak flow according to the metropolitan area network exit proportion; collecting public broadband user number, government and enterprise dial-in user number, public broadband peak user number and government and enterprise dial-in peak user number of the local area network through the network manager of the metropolitan area network, and calculating a broadband user on-line concentration ratio; calculating on-line average bandwidth used by public broadband and government and enterprise dial-in users; according to the past planning data, reckoning the average bandwidth used by public users in the few next years by using a flow curve extrapolation method. The method can accurately predict the future metropolitan area network flow, saves the network bandwidth of the metropolitan area network to the greatest extent, ensures the development of data service, greatly saves the metropolitan area network bandwidth expansion investment for operators, and has relatively good economic values and social values.

Description

technical field [0001] The invention belongs to the field of network planning, and more specifically relates to a method for planning a metropolitan area network. Background technique [0002] The level of development and utilization of information sources and network applications is an important indicator of the degree of social informatization. At present, various public information sources based on IP are increasingly abundant, and various Chinese information and applications suitable for my country's national conditions have brought great convenience to people, and the Internet has gradually become a new type of media; online securities transactions, online bookstores, online shopping, online books Museums, online booking systems and various online cultural and entertainment inventions are gradually becoming popular, changing people's traditional work, study and lifestyle. The Internet has begun to enter people's daily life. Applications appear continuously, and the sound...
