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.
