Re: [dccp] Sequence number validity

[Eddie Kohler]

No, it's not true.  If SWL=0 and seqno=2^47+1, then

seqno < SWL

in circular 48-bit arithmetic.

Hi all,

In section 7.5.3 of the RFC4340 (Sequence-Validity rules) and in pseudocode as well (rfc4340, page 96) the following sequence numbers test is used to make lenient checks for Sync and SyncAck:

 SWL <= seqno

Is it so, that with 48-bit limited sequence numbers that are wrapping around, this test would always be "true"?
