Selecting Servers

An important component of global load balancing traffic is to determine which POP1 should handle an incoming connection. There are many criteria that can be taken into account including: Relative Capacity of different POPs; Relative Load of different POPs; Latency between POPs and client; Network distance between POPs and client.

It is important that when a new connection is received, allocating the connection to the apropiate POP is done quickly. A long and involved process to determine which POP to allocate a connection to will, at best, cause the connection establishment time for the client to be slow. At worst the client may time-out.
