COMPUTATIONAL VIEWPOINT FOR PRE-PROVISIONED ADAPTATION MANAGEMENT Summary The objective of pre-provisioned adaptation management community is to provide link capacity to client-layer(s) from a server layer. This community should be u
7、sed in the case where client transport entities can be provisioned inside the link during the adaptation management. This capability of having pre-provisioned client transport entities is available in technologies such as SDH or WDM. Source ITU-T Recommendation G.854.8 was prepared by ITU-T Study Gr
8、oup 4 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 26th of March 1999. Recommendation G.854.8 (03/99) 1 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standar
9、dization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (W
10、TSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of i
11、nformation 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 term recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that operates a pu
12、blic correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, I992). INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a
13、claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Propem Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the
14、 ITU had not received notice of intellectual property, 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 1999
