2.2.8Point-to-Point Protocol over Ethernet (PPPoE)

Standard PPPoE mode is used when M1112 is operating as a bridge. PPPoE protocol defines how PPP sessions are mapped into Ethernet packets. When M1112 operates as a bridge, this protocol is transparent to M1112.

2.2.9Payload encapsulations

Both routed and bridged protocols are encapsulated in the ATM link by using either RFC 2684 LLC/SNAP encapsulation or VC multiplexing. M1112 also supports PPP over AAL5 encapsulation, in which routed protocols are first encapsulated in PPP (RFC 1661). PPP is then encapsulated in ATM according to the IETF PPP over AAL5 using RFC 2364 VC multiplexing or LLC/NLPID encapsulation.

2.2.10Weighted Fair Queueing (Class of Service)

As a Class of Service (CoS) function, M1112 supports Weighted Fair Queueing (WFQ) for each ATM VCC. The CoS function ensures that different IP traffic flows are treated fairly in the upstream (towards the Internet) direction. This may be necessary, in some cases, because the upstream capacity of the ADSL line is somewhat limited compared to the Ethernet bandwidth on the office or home LAN. The WFQ CoS
