Session-Id AVP is made using following format:
;;[;]
and are decimal representations of the
high and low 32 bits of a monotonically increasing 64-bit value. The
64-bit value is rendered in two part to simplify formatting by 32-bit
processors. At startup, the high 32 bits of the 64-bit value MAY be
initialized to the time, and the low 32 bits MAY be initialized to
zero. This will for practical purposes eliminate the possibility of
overlapping Session-Ids after a reboot, assuming the reboot process
takes longer than a second. Alternatively, an implementation MAY
keep track of the increasing value in non-volatile memory.
is implementation specific but may include a modem's
device Id, a layer 2 address, timestamp, etc.
Example, in which there is no optional value:
accesspoint7.acme.com;**********;523
Example, in which there is an optional value:
accesspoint7.acme.com;**********;523;mobile@200.1.1.88
The Session-Id is created by the Diameter application initiating the
session, which in most cases is done by the client. Note that a
Session-Id MAY be used for both the authorization and accounting
commands of a given application.
