36、Part 2: Framing protocol (HIPPI-FP)FOREWORD1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form thespecialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in thedevelopment of Internation

37、al Standards through technical committees established by the respective organization to dealwith particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Otherinternational organizations, governmental and non-governmental, in liaison with IS

38、O and IEC, also take part in the work.2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC1. DraftInternational Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication asan International

39、Standard requires approval by at least 75 % of the national bodies casting a vote.3) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patentrights. ISO and IEC shall not be held responsible for identifying any or all such patent rig

HIPPI-PH, are passed through thisframing protocol to notify the upper layers of damaged data; provides a connection-less data service; best effort delivery of data, i.e. datagram; connection control information, which may be used for physical layer switching, is supported. 6 11518-2 ISO/IEC:2000

47、(E)INFORMATION TECHNOLOGY HIGH-PERFORMANCE PARALLEL INTERFACE Part 2: Framing protocol (HIPPI-FP)1 ScopeThis part of ISO/IEC 11518 provides data framing for a high-performance point-to-point interfacebetween data-processing equipment. This part of ISO/IEC 11518 does not protect against certainerrors

48、 that might be introduced by intermediate devices interconnecting multiple HIPPI-PHs.The purpose of this part of ISO/IEC 11518 is to facilitate the development and use of the HIPPI incomputer systems by providing common data framing. It provides an efficient framing protocol forinterconnections betw
