The international community has decided to make this standard available only
in the English language version. It has been adopted as a National Standard of
Canada on this basis. This National Standard of Canada is equivalent to International Standard
ISO/IEC 15802-4:1994. 2. Scope The System Load Protocol specification defines a protocol to load the memory of
data processing equipment installed on IEEE 802 networks. To this end the
specification a) Defines the protocol data unit (PDU) formats for loading an end
system.
b) Defines the protocol for loading an end system.
c) Describes the services required of the end system being loaded
(Loadable Device or LD) to successfully complete a load operation.
d) Describes the services required of the end system providing the load
(Load Server or LS) to successfully complete a load operation.
e) Defines the semantic aspects of managed objects of the LD and Ls
that permit the manipulation of the operational parameters of the Ld
and LS state machines, announcement of load servers, and the
third-party initiation of a load.
f) Defines the syntax used when performing management operations via
the IEEE 802.1B LAN/MAN Management Protocol (ISO/IEC DIS 15802-2).
g) Defines the syntax used when performing management operations via
the CMIP Systems Management Protocol (ISO/IEC 9596-1). The specification discusses the LS in only as much detail as is necessary to
define the loading protocol. Management and LS decisions, such as what to do
as a result of LS or LD events or when an LS or Manager fails, are LS and
Manager implementation issues and are beyond the scope of this document. The protocol is specified to convey images consisting of data (in blocks) of
unspecified format. The content and format of data blocks are
application-specific; this standard does not place any constraints on a) The form, content, or meaning of the images that may be conveyed by
means of the protocol;
b) The manner in which data blocks are processed subsequent to their
being received by a loadable device. This International Standard provides the PICS proforma for the System Load
Protocol in compliance with the relevant requirements, and in accordance with
the relevant guidance, given in ISO/IEC 9646-2.
