WHY DOES THE ALTEON APPLICATION ACCELERATOR HAVE LOAD BALANCING FEATURES? WOULDN’T A FULL FEATURED LAYER 4-7 SWITCH BE MORE EFFECTIVE?
Load balancing of backend servers must be performed by the Alteon Application Accelerator when configured for end-to-end encryption, since the Alteon Application Switch will only see encrypted traffic. The available Alteon Application Accelerator load balancing metrics include a hash algorithm on the client source IP address, a round robin algorithm, or a real time measurement of which backend server currently has fewest open connections. Load balancing can also be used in combination with a health check mechanism to minimize the number of failed connections. The load balancing of backend servers can also be combined with cookie-based persistency or session-based persistency.
