Ports and sockets. The session layer only needs to know about a "session", no matter where that session is located on the network. The upper layers use ports, for individual application requests, eg FTP port 23, and each FTP session opened up has a unique socket number. So if you have 2 FTP sessions each will have a seperate socket number. The IP and MAC address do not enter the equation here.
That is my understanding. -Anil -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of mlh Sent: Friday, December 07, 2001 8:00 AM To: [EMAIL PROTECTED] Subject: Does session layer protocol use IP address ? [7:28378] Hi, there, I read Todd Lammle's CCNA2.0 study guide and found this sentence: "Remember that none of the upper layers know anything about networking or network addresses." I am wondering if the session layer doesn't use network address, how can it establish a dialogue with other session layer in other host? Thank you for your time. mlh Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=28391&t=28378 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
