ROSE (remote operations service element)
ROSE (remote operations service element). An Application Layer service definition and
protocol supporting interactive applications, implemented by the RS process in
OSI/MHS. Examples of ROSE PDUs are:
route. A path through an X.400 system from an originator to a recipient.
ROUTE object. An object type, used in OSI/MHS management interfaces, that defines
routing information to the OSI/MHS subsystem. You use the ROUTE object to define
and inquire about O/R names for addressing adjacent MTAs.
route retry. The action taken when an attempt to deliver a message to an adjacent MTA fails
after all links have been tried and exhausted. Route retry occurs when the subsystem
attempts to deliver the message by an alternate route.
route-selection criteria. The attributes that determine the route the message is to take.
routing. The selection of the adjacent MTA to which a message, probe, or report is
transferred.
routing database. A database in the OSI/MHS registration database that contains records of
ROUTE objects and APPL objects.
routing tables. The internal databases that hold the information about the O/R names.
RS (remote operations service) class. The OSI/MHS CLASS object that identifies the set of
all RS groups in an OSI/MHS subsystem.
RS (remote operations service) process. The process in the RS group that implements the
ROSE protocol. The RS interfaces to the Compaq OSI/AS services, manages
associations from RUAs, encodes and decodes messages, and creates and deletes PDUs
in the MR or MS PDU stores as submit and retrieval operations are successfully
completed.
RS (remote operations service) group. The OSI/MHS group that implements the remote
operations service, giving remote user agents access to an X.400 network through a
message store. An RS group consists of a single RS process and a PDU store. There
can be zero, one, or more RS groups in a single OSI/MHS subsystem.
RTSE (reliable transfer service element). An Application Layer service definition and
protocol supporting the reliable exchange of application data, defining such services as
recovery from end-to-end failures and reporting delivery status to the sender. In
OSI/MHS, the RTS process implements the RTSE.
