Source Corrigendum 1 to ITU-T Recommendation Q.816 was prepared by ITU-T Study Group 4 (2001 -2004) and approved under the WTSA Resolution 1 procedure on 13 August 2001. ITU-T Q.816/Cor.l (08/2001) 1 FOREWORD The International T
7、elecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on t
8、hem with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU
9、-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is use
10、d for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU ta
11、kes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual prop
12、erty, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2002 All rights reserved.

14、umber 15 in the list of references, add the following reference: 161 ITU-T Q.82 1.1 (2001), CORBA-based TN alarm surveillance service. 2) Subclause 6.2, Notification Service a b) In the paragraph labelled NOTIF-8, delete the second, third and filth sentences. Replace the paragraph labelled NOTIF-9,
15、along with the indented quote immediately after it, with the following: (R) NOTIF-9 The Notification Service shall support a value for the ConnectionReliability property of Persistent. The Notification Service also shall support a value for the EventReliability property of Persistent (see Note 1) or
16、 BestEfSort (see Note 2). If the implementation of the Notification Service only supports EventReliability = BestEfSort, then it must also support ITU-T Q.821.1 16 alarm synchronization via the Enhanced Current Alarm Summary Control managed object. NOTE 1 - When ConrzectionReliability = Persistent a
17、nd EventReliability = Persistent, the OMG Notification Service requirements state: Each event is guaranteed to be delivered to all consumers registered to receive it at the time the event was delivered to the channel, within expiry limits. If the connection between the channel and a consumer is lost
18、 for any reason, the channel will persistently store any events destined for that consumer until each event time out due to expiry limits, or the consumer once again becomes available and the channel is subsequently able to deliver the events to all registered consumers. In addition, upon start from
19、 a failure the notification channel will automatically re-establish connections to all clients that were connected to it at the time the failure occurred. 4 NOTE 2 - When ConnectionReliability = Persistent and EventReliability = BestEffort, the OMG Notification Service requirements state: The notifi
20、cation channel will maintain all information about its connected clients persistently, implying that connections will not be lost (logically) upon failure of the process within which the notification channel is executing. Any client which connects to the channel using persistent object references ma
21、y fail, but unless these object references raise an OBJECT NOT-EXIST exception, the channel will continue to retry using them. Clients which then re-insantiate objects with these references will (logically) reconnect to their associated proxies. The channel will not, however, store any buffered even
22、ts persistently. The implication of this combination is that upon restart from a failure of the notification channel server process, the channel will automatically re-establish connections to each of its clients, but will not attempt to retransmit any events that had been bufSered at the time the fa
23、ilure occurred. 4 Replace the paragraph labelled NOTIF-1 O, with the following paragraphs: (R) NOTIF-10 The Notification Service shall support the QoS parameter OrderPolicy value FifoOrder, i.e., the channel must support the delivery of events in the order of their arrival when this value is set to
24、FifoOrder. The Notification Service also may support the QoS parameter OrderPolicy value PriorityOrder, i.e., the channel supports the delivery of events in the order of their the value of the priority field in the messages. PriorityOrder should be selected only if Correlated c ITU-T Q.816Cor. 1 (08
25、/2001) 1 Notifications are not in use and the priority in the messages is set by managed object instance (that is, all the notifications emitted by a manage object instance have the same NOTE - The restrictions on the use of priority order are needed to ensure that managing system can determine the
26、state of managed systems from the order of the notifications that they emit. Replace the paragraph labelled NOTIF-1 1, with the following paragraph: (R) NOTIF-11 When the OMG Notification Service is used as the Notification Service, the OMG Notification Service conformance statements shall be suppor
