-GSLB is load balancing multiple POPs /sites, trying to give users closer access to the content, rather than just rrDNS . It' s supposed to be more intelligent
+Load balancing for multiple [PoP]s /sites, trying to give users closer access to the content. Usually done by a NameServer that also knows about the load on the [PoP] s, so that it can swing traffic to the one which is loaded least, similar to an [L4] switch
  
-a GSLB is usually a device which is a [DNS] server that also knows about load on the [POP]s , similar to an [L4 ] [Switch ], so can swing traffic to the one which is loaded least , etc
+This is different from RoundRobin [DNS] using multiple A ResourceRecord~s. It tries to be intelligent about sending connections to locations with low load. Akamai , f.ex., uses a combination of [GSLB ] with [DNS ], ping, traceroute , and [BGP]
