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].

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.
