Hi, While there is a relation due to evolution between Coda and DCE, they are now in different families. The DCE networking protocols are different from those of Coda - and not compatible. DCE/DFS on the client side is indeed closely related to AFS, but not identical. DCE/DFS has tokens, AFS has not. On the server side, DFS is a total re-write and uses the episode file system with the VFS+ layer to export standard server file systems. Coda uses a proprietary format, similar to that used by AFS (but also very significantly different). I wrote a paper comparing these various protocols, which you can read at: http://www.extremelinux.org/activities/usenix99/docs/ Peter Braam > -----Original Message----- > From: mbartz_at_werple.net.au [mailto:mbartz_at_werple.net.au] > Sent: Monday, September 06, 1999 7:22 PM > To: codalist_at_TELEMANN.CODA.CS.CMU.EDU > Subject: Where does Coda fit in relation to DCE? > > > > Hi all, > > I have read quite a bit of the Coda information and it seems to me > that Coda would fit the DCE philosophy quite well. > > I am a bit short on DFS information, but it looks like the differences > are in the integration of DFS with other DCE components like CDS (Cell > Directory Services), DTS (Distributed Time Service), RPC, Posix > Threads.
