Official statements A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered or inferred to be the off
14、icial position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be cons

Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information o
16、r advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments a
17、nd questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed.
18、 For the same reason, IEEE does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is welcome to join the relevant IEEE working group.

Updating of IEEE Standards documents Users of IEEE Standards documents should be aware
25、that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the document together with any amendment
26、s, corrigenda, or errata then in effect. Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the p
27、resent state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE standard.

Patents Attention is called to the possibility that implementation of this standard may require use of subject matter covered by patent right
30、s. By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on
31、the IEEE- SA Website at http:/ standards .ieee .or g/ about/ sasb/ patcom/ patents .html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that ar

The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for condu

Users of this standard are expres

Introduction This introduction is not part of IEEE Std 1903.1-2017, IEEE Standard for Content Delivery Protocols of Next Generation Se
41、rvice Overlay Network. This standard specifies content delivery protocols for a Next Generation Service Overlay Network (NGSON). NGSON supports content delivery from a service to another service, from a service to an end user, from an end user to another end user, or from an end user to a service. N
42、GSON performs cache and forward functionalities and also supports requirements for content adaptation when the source content is in a different format than what the requester can accept. NGSON receives content from the content provider, stores, aggregates, and sends it to the end-user over underlying networks.
