68 SmartBits System Reference
SmartTCP
SmartTCP consists of a set of tests that measure the TCP session performance of server
load balancer devices that make forwarding decisions based on Layer 4 information.
Testing is performed using a SmartBits 200/2000 chassis with two or more SmartMetrics
ML-7710 SmartCards, emulating both the client and server sides of the device under test.
Refer to the SmartTCP User Guide located at http://www.netcomsystems.com/support/
documentation.asp for a complete description of the tests available. Table 6-11 gives a
brief description of these tests.
The following cards can be tested using the following SmartBits chassis:
•
In SMB-200/2000:
– ML-7710, 10/100 Base-TX, SmartMetrics.
– ML-7711, 100 Base-FX Fiber, SmartMetrics.
•
In SMB-600 and SMB-6000B:
– LAN-3201A, 1000-Base Ethernet, SmartMetrics, Multi Mode.
– LAN-3201As, 1000-Base Ethernet, SmartMetrics, Multi Mode.
– LAN-3201B, SmartMetrics, GBIC.

Test Description
Connection Setup Rate Measures the rate of TCP connection establishment
through the device under test (DUT).
Connection Setup Time Measures connection setup time through the DUT as
the rate increases. The graphical results will indicate
any performance degradation which may occur as the
number of open sessions increases.
Session Capacity Determines a DUT’s ability to sustain TCP sessions
over a period of time. It measures the maximum
number of open sessions that the DUT can support.
Session Rate Measures the rate of TCP session setup and teardown
through the DUT.
Connection Teardown Rate Measures the rate at which the DUT closes the TCP
connections.
