Background
• Investment cost reduction and stable network service
A Corporation provides various lines and telephone service through 51 communication service provides in the country. So, it is crucial for them to have stable network. However, they had no actual measurement to prevent harmful traffic in subscription. Such subscription harmful traffic was out of control to A Corporation which required them to have control system to block traffic and to monitor access level condition. They decided to introduce SG2024 for network resource monitoring while keeping closest access level with the customer. They could provide stable network service without expensive equipment.
Details of introduction
• High evaluation for investment cost reduction and harmful traffic prevention capacity
A Corporation reviewed to introduce harmful traffic blocking solution from early 2007 onward. The harmful traffic in the subscription group was hard to block and was a serious threat as it consumed bandwidth of whole network. And as internet phone was introduced to a great deal, harmful traffic had a direct influence on service i.e. the speech quality.
Accordingly they considered two options: one is to secure bandwidth, the other is to block harmful traffic.
First, the secure of bandwidth to cope with harmful traffic required large size L3 switch. But, it was not a fundamental measurement as it required huge investment.
Second was to improve availability of bandwidth by blocking harmful traffic. For this purpose, they reviewed SG2024. The introduction is complete by replacing L2 switch and it equips real-time reaction against zero-day attack without intervention of the administration. Those were merits for introducing SG2024.
A Corporation had many points of harmful traffic as they had many customers. Thus, it is impossible to respond every problem properly. SG2024 provides active prevention/clearance which is also good for cost reduction. Thus, A Corporation decided to introduce SG2024 at the point that is connected to customers.
