I need a HDLC-like framing method with following features:
1) HDLC-based, i.e. compatible with HDLC standard:)
2) Multiplexing - supports parametrized number (up to 65536) of logical channels
3) As few number of extended unneed information (e.g. Packet-Type), as it's possible
I think, there are some HDLC implementations (cisco, 3com, infineon) having these features. It's better to use already developed framing method, than to create a new one.
Please help me to find relevant framing methods and, if possible, implementing source codes, and to compare them.
