Futures Company's Disaster Recovery Center Network Design And Implementation

Futures transaction is the characteristics of market quickly changing, high transaction exposure and strict requirement of the processing speed. Futures company would end in a great loss as soon as the system collapse. For a long time, there had not a completed disaster backup center in futures industry. As stock index futures to be listed on the market, constructing the disaster backup center of futures company appears even more important.This thesis is based on a project of disaster backup center construction in Futures Company. It emphasizes the demand, design, implementation and test of the construction, discussing network topological structure, subnetting, access control strategy, route planning and firewall construction. And the differences before and after the implementation of the project are verified by exemplified methods.There are main works as follows:1. Physical and logical topology structure, subnet access control strategy of trading and OA network during design and implementation of the disaster backup center construction.2. In fact, the network transaction shall not be affected by the subnetting of disaster backup center's trading network and company's OA network3. Finish the network routing of disaster backup center. Make the type3 LSA distribute to the other areas of OSPF by using OSPF Not-So-Stub-Area (NSSA).4. We configured redundant interface to enhance reliability of firewall, using the technology of adaptive safety appliance link monitor.5. We used access control list through the object group technology based on ASA, reduced the resource utility rate of ASA, improved efficiency of data forwarding and increased flexibility of controlling. It indicated that the more the loads are, the more obvious the effect will be.
