31、system for worldwide standardization as a whole. National bodies that are members of IS0 or IEC participale in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technica
32、l committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental. in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/iEC JTC 1. In ad
33、dition lo developing International Standards, ISO/IEC JTC 1 has created a Special Group on Functional Standardicdion (ISO/iEC JTC l/SGFS) for the processing of International Standardized Profiles. An Intcmational Standardized Profile is an intemationally agreed, harmonized document which identifies
34、a standard or group of standards, together with options and parameters, necessary to accomplish a function or set of functions. Draft International Standardized Profiles are circulated to national bodies for voling. Publication as an International Standardized Profile requires approval by at least 7
35、5% of the national bodies casting a vote. S-liaison may be established with JTC I/SGFS by specialized organizations involved in the work of functional standardization. This part of ISOflEC ISP 10609 was prepared with the collaboration of the following S-liaisons: - Asia-Oceania Workshop (AOW); - Eur
36、opean Workshop for Open Systcms (EWOS); - Open Systems Environment Irnplementors Workshop (OIW).

42、SP 10609-14:1994(E) Annex B (informative) Recommenda tions B.l ISODEC 8208 recommendations An implementation should support all non-standard default packet sizes (maximum user data field length) from 32 octets to 4096 octets. B.2 IS0 8802-2 recommendations The recommendations provided in ISO/IEC ISP
43、 1oo9-10, annex C, are valid with the following addition: N1 values up to 4104 Octets should be supported. This is compatible with a Network Layer packet size of 40% octets. B3 ISOIIEC 8802-5 recommendations The MAC sublayer information field lengths that are indicated in ISODEC ISP 10608-13 provide
44、 the potential to operate Token Ring End Systems at maximum throughput for specific, high speed applications. However, the actual information field lengths that can be used at the MAC sublayer for a particular instance of communication between two OS1 End Systems will depend on a number of additiona
45、l factors, such as: the maximum number of octets specified for an LLC I-PDU (Nl); the use of one or more MAC level bridges between the TC53 reference End System and the remote End System (the maximum Service Data Unit size supported by any bridge is the smaller of those supported by the two attachin
46、g LANs). If the TC53 reference End System is communicating, through a MAC sublayer bridge, over an ISO/IEC 8802-3 CSMA/CD LAN subnetwork then the maximum MAC frame size cannot exceed 1518 octets. Also, if two TC53 End Systems are operathg at different data rates (4 and 16 Mbps) through a MAC sublaye
47、r bridge, then the maximum Information Field length will be 4428 octets. 6 STD-BSI BS EN ISP LbOS-L-ENGL 1997 m 1b24bb9 Ob15330 35T BS EN ISP 10609-14 : 1997 BSI 389 Chiswick High Road London w4 4AL Issue 2, May 1997 BSI - British Standards Institution BSI is the independent national body responsibl
