The MIB defines objects related to global keepalive
properties in GSLB devices.  It contains the tables
for keep alive configuration and statistics.  It also
defines related notifications.

Acronyms and their description:

Keepalive    : Keepalive is a method by which the GSLB
               device periodically checks to see if a
               resource associated with an answer is
               still active.  The action of checking is
               known as a keepalive probe.

Shared
-keepalive   : The GSLB device supports the use of shared
               keepalives to minimize traffic between the
               GSLB device and the SLBs(Server Load
               Balancing) that it is monitoring.
               A shared keepalive identifies a common IP
               address or resource that provides status
               for multiple answers.  Shared keepalives
               periodically provide state information
               (online, offline) of the resources
               to the GSLB device.

VIP          : Virtual IP Addresses are used by SLBs to
               represent content hosted on one or more
               servers under their control.  The use of
               VIPs is to route content to the proper
               requesting host without exposing the
               device's internal IP address.

CAPP         : Content Application Peering Protocol(CAPP) is
               a protocol used for intercommunication between
               content switching devices.

Answer       : Refers to resources to which the GSLB device
               resolves DNS requests that it receives.

               There are three possible types of answers:

               Virtual IP (VIP) : Addresses associated with
                                  a SLB, a web server, a
                                  cache, etc.

               Name Server (NS) : Configured DNS name server
                                  on the network that can
                                  answer queries that the GSLB
                                  device can not resolve.

               Content Routing  : A device which uses a
               Agent (CRA)        resolution process called
                                  DNS race to send identical
                                  and simultaneous responses
                                  back to client D-proxy
                                  for proximity determination.
               HTTPHEAD         : The HTTP HEAD keepalive type
                                  sends a TCP format HTTP HEAD
                                  request to a web server at
                                  an address you specify,
                                  returning the online status
                                  of the device (in the form 
                                  of a 200 response) as well
                                  as information on the web
                                  page status and content
                                  size.
