 At the June 2007 meeting of SG15, a new annex to G.998.2 was consented. G.998.2 is the Ethernet
 bonding Recommendation within ITU-T, based on, and heavily referencing, Clause 61 of IEEE
 802.3. Both IEEE 802.3 (Clause 61) and G.998.2 use “G.hs” at initialization to perform
 aggregation and discovery. This new G.998.2 annex defines a frame based protocol, referred to as
 the Bonding Aggregation Control Protocol (BACP), that exchanges information allowing two
 systems to control which PMEs are mapped to which PAFs in a simple and seamless manner. This
 protocol can be used with, or in lieu of, the G.hs discovery/aggregation process.
 The ITU-T would like to utilize the IEEE 802.3 Slow Protocols format for this protocol. This
 protocol adheres to the processing and forwarding behaviour for Slow Protocols as defined in IEEE
 802.3. Specifically, the ITU-T requests a Slow Protocols subtype be allocated to the ITU-T for
 protocol development by the ITU-T. The ITU-T will take further steps to create an additional ITU-
 T subtype so that this and any future Slow Protocol development by the ITU-T would fall under the
 same ITU-T Slow Protocols subtype.
