Re: [load balancing] client response time

Actually, there are a number of global load balancing vendors that perform a proximity metric query. As mentioned in the previous response, some of the requests go to the client's DNS server, but a number of the vendors send it to the client directly. The types of queries used vary from vendor to vendor and can be any protocol (ICMP, TCP, UDP, etc.). The problem with this type of query is that it is dropped on the client's side in many cases as a result of security concerns, so you get the response from some client, but not all.

I am trying to work with some vendors on the client side with a patented way to assist with this problem so this can be a feasible way to obtain accurate measurements from the client or their DNS server.
