1 Scope
The present document describes the signalling behaviour of the transport functions BTF & RCEF for the listed multicast
transport control protocols (IGMP, MLD), and provides a mapping between these transport control protocols and
TISPAN RACS Re interface as specified in TS 183 060 Release 2 [1].

4 Overview
4.1 Overview of multicast transport control protocol to Re
mapping
PULL mode for multicast applies in two cases:
• PULL mode case 1: When it applies below the termination point in the access segment, the PULL mode is
used to request resources for a channel in the access network and/or to indicate that the resources associated to
a channel can be released as the channel is left. This is per user and can be combined with the PUSH mode at
session initiation to allow the A-RACF to download the permitted multicast flow for that user to the RCEF.
• PULL mode case 2: When it applies beyond the termination point, the PULL mode is used to request shared
resources to transport a multicast flow corresponding to a channel that has been requested by one or more
users.
Figure 4.1 shows a generic scenario for both cases of PULL mode. Transport processing nodes comprises one or several
BTFs and one or several RCEFs that may be co localized.

1) Upon session activation, the RACS downloads the policy rules in the RCEF in charge of enforcing policies
applicable to the access segment. This corresponds e.g. to the list of subscribed channels in case of IPTV
service activation. For each policy, bandwidth is set
