Network Performance Assurance

Metrodata offers a comprehensive solution for Network Performance Assurance via the NetTESTER product range, performing both out-of-service testing and in-service background monitoring of your LAN and WAN connections. Efficient networks are is crucial to servicing the many bandwidth hungry "mission critical" applications that are used in modern organisations. With any perceived reduction in service levels always being blamed on "the Network", it is important that network problems can be isolated and resolved quickly.

Network Performance

Typical questions to which Network Managers need clear answers include:

  • How often do our carrier WAN services fail to live up to their expectations?
  • Are we really getting the SLAs that we are paying for?
  • Is my network latency within tolerance for my VoIP services?

Always on

The NetTESTER devices sit within your network and is a highly featured and capable network test and performance monitor. The NetTESTER offers the capability to test the performance of a network upto full 1G wirespeed, over either a copper 10/100/1000BaseT interface or fibre using either 100BaseFX or 1000Base-X SFP modules.

RFC2544, Y.1564 and TWAMP Service Level Test Capabilities

The NetTESTER offers full wirespeed test capabilities supporting RFC2544, Y.1564 and a manually configured Basic Test Mode. It allows for the configuration of the expected service SLA parameters and then performs the tests to verify the performance against the SLA.

In addition to the out of service test capabilities, the NetTESTER can provide performance monitoring through the use of TWAMP.

NetTESTER Testing & Monitoring example applications

OTDR Fibre Measurement & Alarming

OTDR monitoring of 'data over fibre' links without interaction with active equipment terminating each end of the link (e.g. these may be operated by a third party)

OTDR Fibre Measurement and Alarming

Typically (alongside regular NOC functions), for both:

  • Pro-active SNMP 'Trap' alarm reporting, and
  • Re-active interrogation via Browser / Telnet/SSH to NT1003 Management system for more detailed analysis

OTDR Alarming of P2P Ethernet link

OTDR monitoring of critical point-to-point 'Ethernet over fibre' links of up to 1Gbps

OTDR Alarming of P2P Ethernet link

Typically (alongside regular NOC functions), for both:

  • Pro-active SNMP 'Trap' alarm reporting, and
  • Re-active interrogation via Browser / Telnet/SSH to NT1003 Management system for more detailed analysis

Network 'Circuit Activation Testing'

'Y.1564' circuit activation testing can be conducted to any remote branch location, independently of other links which may be running live data. Testing verifies that 'Committed Information Rate' is being achieved and reports Latency, Jitter and potentially Packet-loss Ratio for the new link, whilst regular traffic to other sites is running through the HQ link.

'RFC2544' profile testing could alternatively be used for individual Pt-to-Pt. links

Network 'Circuit Activation Testing'

Operatives at the NOC can remote log-in to the NetTESTER to:

  • Configure and setup
  • Initialise tests
  • Monitor Test Progress
  • View test reports

In-service Performance Monitoring

TWAMP 'background' monitoring can be used to generate alarms to the Network Operations Centre in the event that (Latency, Jitter, Packet-Loss) becomes out-of-specification and breaches pre defined 'Service Level Agreements' for each link.

In-service Performance Monitoring

Operatives at the NOC can remote log-in to the NetTESTER to:

  • Configure SLA thresholds
  • Initiation of background monitoring
  • SNMP 'Trap' alarm reception (SLA breach)
  • Further investigation by individual unit log-in
