Object
Indicates if the lightweight registration functionality is enabled.
disable : the group does not use the lightweight registration functionality.
The group does not include the timeToLive field in the
registrationRequest message.
enable : the group uses the lightweight registration functionality. The group
includes the timeToLive field in the registrationRequest message.
For the lightweight registration functionality, the following RAS message
fields are used:
- keepAlive field of the registrationRequest message. The keepAlive field is
either true or false.
- timeToLive field of the registrationRequest and registrationConfirm messages.
The timeToLive field is a number of seconds.
- A full registrationRequest message has the keepAlive field set to false.
- lightweight registrationRequest message has the keepAlive field set to true.
When the lightweight registration functionality is enabled, the group follows
these steps:
step 1 : the group sends a first registrationRequest message to the gatekeeper.
This registrationRequest message has the keepAlive field set to false
and contains the timeToLive field. The value of the timeToLive field
is configurable.
step 2 : If the registrationConfirm message contains the timeToLive field, the
group sends lightweight registrationRequest messages. The interval
between each lightweight registrationRequest message is one-third of
the timeToLive value from the gatekeeper (from the registrationConfirm
message). On a network with heavy traffic, a lightweight
registrationRequest message could arrive a few seconds late at the
gatekeeper. Furthermore, since the RAS channel between a group and a
gatekeeper is unreliable (UDP), a lightweight registrationRequest
message may never arrive at the gatekeeper. These problems are avoided
by using an interval equal to one-third the timeToLive value of the
registrationConfirm message.
step 3 : If the registrationConfirm message does not contain the timeToLive
field, the group does not send lightweight registrationRequest
messages.
