♦ITU G.991.2 Annex E for Ethernet, also known as EFM or 2Base-TL, as defined in IEEE 802.3ah

♦Up to 8 IP interfaces for EFM/2Base-TL

♦IP QoS classification, Marking, scheduling and shaping

♦802.1Q VLANs

5.Routing protocols:

•Static routing

•RIPv1 - RFC 1058

•RIPv2 - RFC 2453

•OSPFv2 - RFC 2328

7.WAN access via PPPoE, PPTP, L2TP, DHCP.

8.Quality of service (QoS):

•Traffic Classification and Marking:

♦Connection-based (with SPI) or packet-based classification.

♦VoIP classification for both SIP signaling and media traffic: tracking UDP ports selected by SDP offer-answer negotiations.

♦Explicit classification criteria:

Source/destination MAC and IP addresses

Protocol (ALG-based)

L4 port numbers

DSCP/802.1p

Length of packets or their data portion only

♦DSCP and 802.1p marking

•Traffic scheduling and shaping:

♦Ingress traffic policing

♦Traffic reservation - when not utilized, other classes are served with extra bandwidth

♦Maximum egress traffic shaping

♦Scheduling: Strict Priority, Fair, Weighted Round-Robin Queuing, and Class- Based WRR Queuing

♦Queue management:
