Design And Implementation Of Optimization Project For Information Network Of Shandong Post

In recent years, to ensure application systems of the Shandong Postal Green-card Network and Integrated Network to be in motion one by one, Shandong Postal information Network has been adjusted continuously, but construction of the two Network lacked unified planning, backbone equipment aging seriously; connecting the Integrated Network of Center Office with Provincial Center lacked backup equipment and backup line; 7 Non-center Office connected by senrial port profile with Integrated Network by linking to affiliated Center Office, the structure of the whole network was very complex and failure rate was very high; Green-card Network interoperated with each other in province and out province by routing with significant safe hidden trouble, etc. To solve the above problems, Shandong Post optimized Green-card Network and Integrated Network.This article introduces the program and design scheme for the optimization of Shandong Postal network in detail, also the scheme and steps for the adjustment and graft of the whole network. First of all, this article introduces the situation and the problem of the network before modification, the objective and contents of the reconstruction. Next introduces the reconstruction program of Shandong Postal Green-card Provincial Center Network, the reconstruction program of backbone network in Shandong province; the reconstruction program of up-connecting in every city(take Tai' an branch for example); proposal for wiping of the whole network. Finally, the problems of the optimization and the effect of the optimization are described. The author participates in a sequence of tasks, including initial researching, drawing up scheme, selecting equipment, signing the order, carrying out the project and post maintenance, etc. Now, modification works of the whole provincial network have been finished, so the two Networks run stability.After the accomplish of the project, when one of the two Networks go wrong, the other can switch over to back-up line, then make sure the business operate well. Green-card Provincial Center isolate the router among provinces, that can decrease the burden of the router, screen malfunction in other provinces towards Shandong.
