Research On The Construction Of Network Disaster Recovery Center In Jinan Branch Of B Commercial Bank

With the rapid development of information science and technology,in order to improve its market competitiveness,the financial industry has increasingly relied on the information system to support business.Because of this dependence and the unpredictability of disaster,how to ensure the stable operation of information system and business interruption is the key problem faced by the financial sector today.If there are many catastrophic and destructive security risks in the banking business system,in this situation,once the disaster comes,the data center business system will run slowly or even be interrupted.If the business can not be recovered for a long time after the interruption,it will directly affect all branches and business outlets covered,and cause serious economic impact and trust loss on the social and financial system order.According to the warning record of banking technology risk issued by China Banking Regulatory Commission,if the bank information system is interrupted for one hour,the basic payment business of the bank will be directly affected;if the information system of the bank is interrupted for one day,the event will seriously damage the reputation and market value of the bank;if the information system of the bank is interrupted for 2 to 3 times,the bank's basic payment business will be directly affected The stability of the bank and even the whole financial system will be directly harmed.Therefore,disaster recovery system is the most important.When the disaster comes,how should the financial sector,especially banks,face it?In order to ensure the continuity and security of banking business,banks have successively carried out various disaster recovery system backup and recovery projects,with the intention of "preparing for a rainy day and being prepared".Among them,the construction of local network disaster recovery center has become the focus of banking industry.Therefore,it is of great practical significance and practical value to study the construction of local network disaster recovery center of commercial banks.The main content of this paper is.about the construction research and project implementation project of B Commercial Bank Jinan Branch City Network Disaster Recovery Center.The main work and contributions of this paper are as follows:1.Based on the development status at home and abroad,combined with practical cases,this paper expounds the necessity and importance of building disaster recovery system;on the basis of interpreting the concept,technical indicators and disaster recovery level of financial industry disaster recovery system,this paper analyzes and compares the construction mode,layout mode,physical requirements and main technologies of disaster recovery center of commercial banks.2.According to the network structure,network status,flow path,secondary branch and community bank traffic of Jinan Branch of B commercial bank,this paper investigates and investigates the existing security risks;according to the regulatory requirements and the business development strategy of Jinan Branch of bank B,it formulates reliable,available,safe,unified,open standard,flexible and scalable,manageable and mature technology Advanced design principles,determine the use of part of the old,part of the new combination of construction principles.3.Completed B Commercial Bank Jinan Branch of the city network disaster recovery system design and research.According to the routing entries,OSPF(open shortest path first)/BGP(border gateway)is proposed Protocol(border gateway protocol)routing protocol,lists the related device configuration scripts,and describes the advantages and disadvantages of the scheme,and realizes the routing strategy of the existing network of Jinan Branch of commercial bank B,that is,the routing strategy of branch and head office before and after migration,route selection,upstream and downstream traffic,and backhaul traffic before and after migration are not changed The remote disaster recovery of production center is realized,and the ability to resist disaster events is improved.4.In order to test the redundancy and the stability of the backup system of the core sub district and community bank and business area network system of bank B's Jinan branch connecting the branch network within its jurisdiction,and simulating various obstacle accidents,various switching test schemes about the accident occurred in the local network disaster recovery center were planned.In order to improve the practical operation ability of maintenance personnel,the daily maintenance process and simple troubleshooting operation of local network disaster recovery center system are introduced.
