1 INTRODUCTION
The Metrodata NetTESTER NT10G05 is low cost, but highly featured and capable
network test and performance monitor. The NT10G05 offers the capability to test the
performance of a network up to full 10G wire speed. The 10G network port is
presented as an SFP+ module. In addition to out of service testing, the performance
of the network may be monitored for several key SLA performance metrics.
The NT10G05 offers full wire speed test capabilities supporting RFC-2544, Y.1564
and a manually configured Basic Test Mode. The NT10G05 allows for the
configuration of the expected service SLA parameters and then performs tests to
verify the performance against the SLA. A birth certificate report is produced as
evidence of the test including the key metrics of frame loss, latency and jitter.
The NT10G05 can operate as a tester at layer 2, where the destination MAC
address and VLAN is required, or alternatively at Layer 3/4 where IP/UDP test
packets are sent to a peer IP address.
In addition to the test generation capabilities the NT10G05 can also act as a simple
loopback reflector device operating at layer 2, performing a MAC SA/DA swap
function; at layer 3, additionally performing an IP address swap for packets received
with the configured protocol or finally at layer 4 where the UDP port numbers are
also swapped for a configured UDP service.
In addition to the out of service test capabilities, the NT10G05 can provide a
performance monitoring capability using TWAMP, Two Way Active Measurement
Protocol. TWAMP is a server/reflector type function and the NT10G05 can act as
either, or both, Server supporting up to 64 monitoring sessions, or reflector where all
received TWAMP packets are time stamped and reflected towards the generator.
For timestamp accuracy, hardware timestamping is performed giving a sub
microsecond accuracy.
The performance monitoring function will monitor the service between server and
reflector against a configured SLA measuring synthetic packet loss, latency and
Jitter with the statistics being stored for up to 30 days.
