load balancing and fault tolerance without load balancer
by Joe Shen 17 Mar '08

17 Mar '08

hi, we plan to set up a web site with two web servers. The two servers should be under the same domain name. Normally, web surfing load should be distributed between the servers. when one server fails, the other server should take all of load automatically. When fault sever recovers, load balancing should be achived automatically.There is no buget for load balancer. we plan to use DNS to balance load between the two servers. But, it seems DNS based solution could not direct all load to one server automatically when the other is down. Is there any way to solve problem above? we use HP-UX with MC-Service Guard installed. thanks in advance.

IPv6 on SOHO routers?
by Frank Bulk - iNAME 14 Mar '08

14 Mar '08

Slightly off-topic, but tangentially related that I'll dare to ask. I'm attending an "Emerging Communications" course where the instructor stated that there are SOHO routers that natively support IPv6, pointing to Asia specifically. Do Linksys, D-Link, Netgear, etc. have such software for the Asian markets? Furthermore, he stated that networking equipment companies like Cisco will be moving away from IPv4 in 5 years or so. This is the first time I've heard this posited -- I had a hard believing that, but he claims it with some authority. Anyone hear anything like this? My own opinion is that we'll see dual-stack for at least a decade or two to come. Frank
