Donghua huaxa Bank implements refined business monitoring and O & M Management (1)

I. Status Quo Analysis

With the rapid development of Huaxia Bank's business and the deployment of various network-based business applications, the wide area networks (WANs) from the headquarters to the first-level and second-level banks have carried various business operation data of the bank. However, with the normal application traffic, the abnormal traffic on the network also comes along, and even the abnormal network traffic seems to occupy a lot of CPU and memory resources of the network device system) and network bandwidth resources, resulting in network congestion, resulting in network packet loss and increased latency, may eventually cause the entire network paralysis, such as the Minsheng Bank Network paralysis event ).

As the business of the entire bank is gradually concentrated, the online businesses of the entire bank are integrated in a unified manner to unify key business applications within the business network and strengthen the protection of key business priorities. There are more and more applications on the network, and the network administrators have limited means of monitoring, controllability, and predictability of these applications. Although Huaxia Bank already has a network management center for IT infrastructure construction, IT is responsible for managing the entire network. However, in terms of refined business monitoring and O & M management, the main problem currently exists: the visibility and controllability of business applications are weak.

◆ Reduced network transparency:

-Increasingly complex network conditions, and a large number of emerging applications are emerging

-Lack of overall control over network-wide traffic

-Unable to achieve refined analysis of network traffic

◆ A large amount of unknown traffic occupies network resources:

-Various Network Traffic swallowed up bandwidth

-Non-critical applications cannot be managed

-Abnormal traffic threatens network security

◆ Reduced network stability and security:

-Occasional network congestion

-Key applications cannot be guaranteed

-Viruses and network attacks may cause network Paralysis

With the development of business and the increase of network data volume, the Bank's business network is facing the shortage of Bandwidth Resources. Although increasing bandwidth can temporarily solve the pressing problem, it will bring about a significant increase in network rental fees, and it is still a temporary solution. When the bandwidth of a business integration system is large, the application occupies a large amount, and the real-time bandwidth is always maximized. This can cause serious waste of network resources.
