Abstract

   This memo defines the protocol and the Management Information Base
   (MIB) for performing response time data collection on TN3270 and
   TN3270E sessions by a TN3270E server.  The response time data
   collected by a TN3270E server is structured to support both
   validation of service level agreements and performance monitoring of
   TN3270 and TN3270E Sessions.  This MIB has as a prerequisite the
   TN3270E-MIB, reference [20].

   TN3270E, defined by RFC 2355 [19], refers to the enhancements made to
   the Telnet 3270 (TN3270) terminal emulation practices.  Refer to RFC
   1041 [18], STD 8, RFC 854 [16], and STD 31, RFC 860 [17] for a sample
   of what is meant by TN3270 practices.
