\outl0\strokewidth0 \strokec2 The\'a0Multicast\'a0Working Group is being reconstituted and charged by the NTAC with making a recommendation about the state and use of native\'a0multicast\'a0on the Internet2 backbone. Secondarily, the working group will also consider recommendations to connectors, campuses, and peers as to their use of any Internet2 backbone native\'a0multicast\'a0services.\cb1 \

\cb3 There have been a number of events that have prompted this activity:\cb1 \

\outl0\strokewidth0 \strokec2 Any-source\'a0multicasting\'a0(ASM) has been deprecated for use in the interdomain context (RFC 8815), leaving source-specific\'a0multicasting\'a0as the remaining mode of operation for interdomain\'a0multicast;\cb1 \uc0\u8232 {\field{\*\fldinst{HYPERLINK "https://tools.ietf.org/html/rfc8815"}}{\fldrslt \cf4 \cb3 \ul \ulc4 \strokec4 https://tools.ietf.org/html/rfc8815}}\

\outl0\strokewidth0 \strokec2 Many connectors\'a0and campuses have either discontinued support for\'a0multicast\'a0or have allowed\'a0multicast\'a0support to atrophy;\'a0\cb1 \

\outl0\strokewidth0 \strokec2 The implementation of the new packet platform of the Next-Generation Infrastructure project provides an opportunity to reevaluate what services should be offered by and to the community;\cb1 \

\outl0\strokewidth0 \strokec2 Automatic\'a0Multicast\'a0Tunneling (AMT) is under active development by the IETF and provides a new overly deployment model for\'a0multicast\'a0without requiring end-to-end support of native\'a0multicast\'a0by all the network infrastructure between\'a0multicast\'a0sources and their receivers;\cb1 \
