Enumeration
The throughput can be enhanced up to factor three using the V42bis compression method or the Stac LZS compression algorithm. V42bis is currently supported with the ip-lapb and mpr-lapb encapsulation. Stac LZS compression algorithm is provided using PPP encapsulated links, stac(3) indicates support of Sequence checking, ms-stac(4) indicates support of Extended mode which is prefered by Microsoft. Both check modes are implemented according RFC 1974. When set to mppc(5), the Microsoft Point-to-Point Compression (MPPC) Protocol according RFC 2118 is negotiated. MPPC uses an LZ based algorithm with a sliding window history buffer.
