TLS uses SHA-1 or MD5 in ciphersuite for message integrity verification. If bytes lost happens during transferring, the message will be dropped by TLS. That is also the cause that we need a security mechanism for Syslog.
As for error of encoding/decoding, I believe if an application does encoding/decoding in a wrong way, you must not expect it do it right with other mechanism, such as LF. Redundancy to improve robustness is good idea, but I don't think it applies to this case. > -----Original Message----- > From: Tom Petch [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 20, 2006 8:43 PM > To: [EMAIL PROTECTED] > Subject: Re: [Syslog] delineated datagrams > wasdraft-ietf-syslog-transport-tls-01.txt > > I wonder if others share my concern about the lack of > robustness in the way in which datagrams are delineated in > the stream protocol (a TCP rather than a TLS issue). > > The system works as long as > - the frame length is encoded perfectly > - the frame length is decoded perfectly > - no bytes are inserted or removed in error which is > doubtless true in some networks, but I would prefer not to rely on it. > > So, when an error occurs, can the Collector/Relay detect it? > Can the Collector/Relay recover synch?
