Planning And Design Of Official Network Platform Of Langfang City

According to the requirements of Hebei Province "with regard to the building of the province's e-government network integration views" and integrating the program, in order to comprehensively promote the building of e-government in Langfang City, official network platform Langfang City Planning and Design tasks are raisedThe official network platform of Langfang City construction, avoids the network redundant construction, reduces e-government operating costs ,and promots the building of " Economizing Government"; by improving the utilization of network and information resources, provids convenient access to information means be conducive to strengthening the party committees , the government's regulatory capacity and integrated emergency command and dispatch capabilities; further through online processing, administrative transparency, and expanding the channels of communication with the public, the implementation of governing for the people thinking, resolve contradictions, promote the building of "a harmonious society", "highly efficient government."By the network construction and application of information systems investigation, consulting, demand analysis of the main administrative departments in Langfang City we access to first-hand information. Through multi-channel collecting related literature of network planning and design, the vertical and horizontal contrast, collate and summarize we propose network platform Langfang overall technical line. Further through comparison other provinces, municipal e-government network-building programs, learning from the successful experience, designe Langfang City official network platform.Langfang City public network platform uses Gigabit Ethernet technology, satellite-based network topology and hierarchical design model. Through the various routing and switching equipment vendors and products in comparative studies, considered features, performance and price, and other factors, the core layer equipment and equipment are selected for the convergence of the high-end router NE80 and Huawei 10 Gigabit Switch S8512; optical fiber transmission access network uses SDH (Synchronous Digital Hierarchy) technology; optical transmission reuse system are composed a MSTP flexible equipment H9MO-LMFIT developed by HuaHuan Ltd.and ingle-core bare fiber Leasing communications operator, transmiting internal and external network data, and achieving the data physically isolated.Langfang City public network platform design innovation lie in the use of SDH optical reuse transmission and achieves internal and external network data transmission by single-core optical fiber and achieve physical isolation, thereby saving fiber resources, reduce lines operating costs.
