So was SDLC derived from HDLC (by removing the balanced modes), HDLC derived from SDLC (by adding the balanced modes), or were both derived from some third protocol? Guy Harris 10:48, 27 December 2005 (UTC)
Extra information?
Should the section on bit stuffing be reduced to a simple link to the bit stuffing page?
No, it was the other way around. The original SDLC was asymmetric and when it was taken into the US ANSI committee X3S3 it was extended to a symmetric mode as well.
My question is how can you have a history section with no dates!? When did HDLC work start and when was the first version of the standard approved?
