Dear Sir,

What are the main difference between the geographical and local load balancer with regard to foundry server iron product line ?

How stickiness is maintained on these boxes ?

Thanks,

The Foundry Networks ServerIron switch provides Server Load Balancing features and can switch up to a full gigabit of HTTP traffic to the cache cluster. The ServerIron switch provides multiple mechanisms for hashing clients-to-NetCache servers. Using bit masks, the hashing mechanism can be keyed on the source and destination IP addresses and port numbers or only the destination IP address (so as to best exploit persistent connections). The ServerIron switch uses physical link, ICMP (ping), TCP SYN-ACK, and HTTP mechanisms for detecting cache failure and re-mapping to a different cache or cutting through directly to the Internet. Foundry's ServerIron switches can be deployed in failover pairs and can also provide full-duplex connection to groups of cache servers through downstream switches.
