Appendix A

The networking methods of BNG pool

This appendix describes the possible networking methods for members of the BNG pool.

(1) Members of the BNG pool interconnected (2) Members of the BNG pool interconnected
via aggregated switches via virtualized switches

(3) Members of the BNG pool interconnected (4) Members of the BNG pool interconnected
via switches with full-mesh connections via OTN network

Figure Ap.1 – The networking methods for members of the BNG pool

The BNG pool is composed of multiple BNG devices from the same Central Office or different Central Offices.
Members of the BNG pool are inter-connected by the underlay L2 network. The networking methods for
members of the BNG pool can be classified by the following four types:
– Inter-connection via aggregated switches. The aggregated switches form an underlay layer 2
network by inter-connecting each other, and members of the BNG pool establish connections
among them via the underlay layer 2 network. This networking method requires transmission
resources among the aggregated switches.
