Greetings and apologies in advance if this is a FAQ! I currently have my boss's Sun3/50 (located at his house) tied into our network via a SUN 4. They are both running SunOS 4.1 with SLIP. He's using the line mainly for rlogining to our various machines to keep an eye on things when he's at home ;-). I would like to see if I can get better interactive performance for him. A friend recommended CSLIP for this. However, I'm wondering if it would be better to use PPP? I'm not familiar with the trade-offs between the two. Some of my concerns are robustness, performance, and expandability. I believe that in the near future (i.e., probably this summer), other people will want to tie in to the network as well. If so, we would like the option of moving PPP/CSLIP from the Sun 4 to a router. To sum up my ramblings: for interactive response (quick rlogin response), should I choose PPP or CSLIP? Which is better for over-all general performance?

Most PPP implementations do not have VJ header prediction/compression. Bottom line is that you are probably better off performance-wise with CSLIP unless you can find a PPP implementation with VJ compression. There have been some recent changes to the PPP spec re VJ compression so be sure what you get conforms to the latest changes. -- Brian Lloyd, WB6RQN Telebit Corporation Network Systems Architect 1315 Chesapeake Terrace brian@napa.telebit.com Sunnyvale, CA 94089-1100 voice (408) 745-3103 FAX (408) 734-3333

I thought that the current PPP version for Suns (available on uunet) has VJ header compression. I'm running that version, and it works well. The performance also seems very good. -Dave
