11 Information management 11 Groep T Leuven – Information department 11/15 RFC’s : Request for comment Werkdocumenten voor de Internet Community Standaarden worden gepubliceerd in RFC’s Vijf classificaties: –Required, recommended, directional, informational, and obsolete Ontwikkeld op basis van consensus

12 Information management 12 Groep T Leuven – Information department 12/15 RFC’s : Example 2328 OSPF Version 2. J. Moy. April (Format: TXT= bytes) (Obsoletes RFC2178) (Also STDO054) (Status: STANDARD) 2178 J..Moy,.OSPF yersion 2., 07/22/1997. (Pages=211) (Format=.txt) (Obsoletes RFC1583) 1583 J. Moy, nosPF Version 2., 03/23/1994. (Pages=212) (Format=.txt, :ps) (Obsoletes RFC1247) (Obsoleted by RFC2178) 1247 J. Moy,.OSPF Version 2n, 08/08/1991. (Pages=189) (Format=.txt,.ps) (Obsoletes RFCl131) (Obsoleted by RFC1583) 1131 J. Moy, nosPF specificationn, 10/01/1989. (Pages=107) (Format=.txt,.ps) (Obsoleted by RFC1247)

13 Information management 13 Groep T Leuven – Information department 13/15 RFC’s : Example Mailer software MUST be able to send and receive messages of at least 64K bytes in length (including header), and a much larger maximum size is highly desirable. Host software MUST handle hostnames of up to 63 characters and SHOULD handle hostnames of up to 255 characters.
