Network Managers need to understand critical characteristics including Throughput, Delay (a.k.a. Latency), Delay variation (a.k.a. Jitter) and Packet loss, in order to support both critical Corporate applications and an ever-increasing array of new mobile applications introduced by the 'Bring Your Own Device' (BYOD) paradigm of today's generation of 'switched on' users. Modern packet-switched Wide-Area Networks (WANs), whether based on MPLS-derived IP-VPNs or Carrier Ethernet infrastructures, lack the well quantified, deterministic nature of earlier generation connection-oriented SDH/PDH networks. Service Providers themselves have generally been poor in monitoring their own performance characteristics right out to the point of customer connection, so offer little by way of assurance to their users.
NetTESTER provides the tools Network Managers need to fully test LAN and WAN performance 'on demand', using low cost, always available, test devices embedded within the Enterprise network. Operating under remote management control within both Switched and IP-Routed infrastructures, and supporting RFC2544 and ITU-T Y.1564 test profiles, NetTESTER devices generate test traffic, perform line-rate loop-back with address-swapping, and submit network health reports back the Network Control Centre, as a vital aid to performance verification and trouble-shooting.
The NetTESTER family of Network Performance Assurance products enables out-of-service testing and in-service background monitoring of your LAN and WAN connections. NetTESTER devices sit within your network and perform a background analysis of the performance of your network.
