node type translates frames in to and out of ATM LLC encapsulation,
as specified by RFC 1483.
In LLC encapsulation the protocol of a given protocol data unit (PDU) is
specified by an IEEE 802.2 LLC header, possibly followed by an IEEE 802.1a
SubNetwork Attachment Point (SNAP) header.
This node currently handles the Ethernet and FDDI protocols.
The node transmits and receives ATM PDUs on the
Received PDUs are decoded and forwarded to the
hooks as appropriate.
Data received on the
hooks are assumed to be full Ethernet or FDDI packets as appropriate and are
encapsulated into a PDU and transmitted via the
