BSD compresion pouziva LZW algoritmus s kterym jsou licencni problemy.
deflate compression pouziva  Lempel-Ziv LZ77 compression (viz zlib).
Krome toho je jeste PPP Stac LZS Compression Protocol (vyvinul  Stac
Electronics) a PPP LZS-DCP Compression Protocol (LZS-DCP), ktery je

	PPP Gandalf FZA Compression Protocol
        PPP Predictor Compression Protocol 
	Microsoft Point-To-Point Compression (MPPC) Protocol
