ITU-T J.706-2012 (预发布)目标容量分配的概述

The target content distribution is the mechanism for content distribution addressed to specific target users according to a set of distribution policies and specific interactive feedback from the platform to content providers/Ad providers. This [draft] Recommendation defines the overall architecture of the target content distribution system on the platform, including the relationship of [ITU-T J.707], which defines the messages between the platform and content providers/Ad providers, and [J.380.1] series. Also, this Recommendation seeks to clarify the relationship between the target content distribution system and other relevant Recommendations such as H.IPTV-AM. This Recommendation illustrates each interface as well.

ITU-T Y.1305 FRENCH-2006 (预发布)虚级联信号的链路容量调整机制(LCAS),也列为G.7042

This Recommendation specifies a link capacity adjustment scheme that should be used to increase or decrease the capacity of a container that is transported in an SDH/OTN network using Virtual Concatenation. In addition, the scheme will automatically decrease the capacity if a member experiences a failure in the network, and increase the capacity when the network fault is repaired. The scheme is applicable to every member of the Virtual Concatenation group. This Recommendation defines the required states at the source and at the sink side of the link as well as the control information exchanged between both the source and the sink side of the link to enable the flexible resizing of this Virtual Concatenated signal. The actual information fields used to convey the control information through the transport network are defined in their respective Recommendations, ITU-T Recs G.707/Y.1322 [1] and G.783 [3] for SDH and ITU-T Recs G.709/Y.1331 [2] and G.798 [4] for OTN.
