The Nokia Big-IP 2000 Application Switch controls and manages local traffic by using Layer 7 intelligence to make load balancing decisions. The device, designed by F5 Networks, adds to the line of application switches in Nokia's Internet Traffic and Content Management (iTCM) range, which aims to ensure high availability of Web applications and services.
Switching is performed according to business rules set by the system manager, and each packet is inspected to determine its Layer 7 details. Based on this and the rule base, the correct way to forward the packet is determined to route it to the designated resource or application within a datacentre.
The Big-IP switch can be deployed singly or as a redundant pair to ensure availability in mission-critical environments. It has two Gigabit Ethernet ports with 16 Fast Ethernet ports and includes on-board SSL (Secure Sockets Layer) acceleration to offload these processor-intensive operations from the application servers to increase overall performance.
The Nokia iTCM Big-IP product line also includes the Fireguard 520 appliance, the HA+ 540 appliance and the 5000 application switch.
