Hi Bhupesh, 1. Size of packet is determined by its payload and header length. Length of data is 16bit value in IP header, the data vary from 20 (size of header portion) to 65535 bytes assuming. 2. Like I said it depends on data and the underlying transport mechanism used to send SIP message. Refer sec 18.1.1 "Sending Requests" of 3261 for details. 3. Size is variable.
Hope this helps ! -Sameer Sawhney -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bhupesh Rautela Sent: Wednesday, August 25, 2010 4:47 PM To: [email protected] Subject: [Sip-implementors] How many SIp messages in One IP packet ? Hello, I had some basic questions, i hope people don't mind answering. 1. What is the size of an IP Packet ? 2. Is one SIP message, example, an INVITE or an ACK, transmitted over one IP packet or more than one IP packet ? Are IP packet sizes fixed or variable (according to the SIP message size) ? 3. Is size of an IP packet 476 bytes ?
