This document is identical to SCTE 168-7 2010 except for informative components which may have been updated such as the title page, NOTICE text, headers and footers. No normative changes have been made to this document.
This Recommended Practice is to give guidance about detecting errors in the IP Transport
network used for the delivery of media services including Video and Audio streams of data
with the associated control information to provide MPEG transport through an IP network.
The IP Transport Layer operates in conjunction with other Application and Physical
component layers that could also generate network impairments, this document will focus
on the effect these impairments have on the detection of the cause of problems in the
delivery of media services. Common IP network events and failures are characterized with
their impact on the MPEG transport stream in a functioning system. Every network layout
is different and presents unique configuration challenges; this document does not provide
guidance on configuration of the network but does provide background information on the
individual components of the IP network as well how the IP transport network operates in
a multimedia network.
This document describes the protocols within the IP network and the possible IP layer
causes of media impairments but does not provide metrics that correlate specific IP failures
to media impairments. Industry accepted metrics have been provided for IP packet loss,
delay and jitter.
This background on the IP network layer provides guidance to operators who are planning
to deploy or are currently deploying MMM systems and, where appropriate, refers to other
HMS-MMM documents that provide supplemental information about other network
components outside of the IP Transport Network.
