hi.... maybe, ... if you designed a new protocol, there would be no rules whether you make in ASN.1 or some other ways.. as you know, the encoded messages from ASN.1 are not readable to human beings, but it is widely applicable and more compact. it depends on your own purpose.
mm... The followings would be a good example for you. There are 3 different kinds of protocols in VoIP networks. (H.323, MGCP and SIP) the first one uses ASN.1 and the others not. The ASCII code is applied for them.(you may understand as soon as you see.) I heard the reason why they cannot use ASN.1 is that it is too complicated to read the message without Analyzer and VoIP networks is concentrating on IP products such as http, ... absolutely, H.323 is oldest one in 3 and less popular. hope this helps... best regards... ----- Original Message ----- From: "ajay singh" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, September 27, 2003 6:40 PM Subject: [ASN.1] why ASN.1 is used in some protocols and not in others > Hi All, > I have been asked this question many times. > Why ASN.1 is used in certain protocols only and why > not in others? > > Are there any criteria to use ASN.1 ? > > Ajay > > ________________________________________________________________________ > Yahoo!
