Verify Ethernet Services over Electrical and
Optical Links VLAN, Q-in-Q tags, and MPLS Testing


Typically, Ethernet services are deployed to customer using a combination of fibre optics and electrical links as depicted in the diagram. The data rate ranges from 10 Mbps through to 10 Gbps in capacity.

GL’s PacketExpert™ is a compact portable platform that can be used for testing packet based Ethernet & Optical networks at all layers - from physical layer to service layers. The appliance is available is many forms – from a High-density 12/ 24-Port, Portable 4-Port, to Handheld 10G.

A portable (USB based) Quad Port PacketExpert™ has 4 Electrical Ethernet ports - 2 of the 4 ports can be Electrical or Optical ports, enabling testing on optical fibre links as well. The electrical ports support 10/100/1000 Mbps, and optical ports support 1000 Mbps  (1 Gbps) using SFP. Each GigE port provides independent Ethernet/VLAN/MPLS/IP/UDP testing at wire speed with modules such as BERT, RFC 2544, Loopback, Record/Playback, IPLinkSim™, and ExpertSAM™.

Wire Speed BERT IP WAN Link Emulation

Handles Wirespeed BERT, in both directions, on all available ports. Send and receive different BER test patterns through Ethernet frames (standard and customized) at user-defined frame rates. This tests the routers’ ability to route IP packets correctly at various speeds, and measure the ability of various routers on the path to forward IP packets in sequence and without dropping.

Traffic options lets technicians generate Ethernet frames with user-configurable frame length, and frame size with varying traffic rates. The payload (or pattern) of received frames are analysed in detail to detect and monitor mismatch in the payload and other Ethernet error conditions.

PacketExpert™ IPLinkSim™ is an important and simple to use tool that simulates IP WAN links using a portable hardware based unit. Connect a PacketExpert™ unit in series with existing optical or electrical links, and introduce different impairment type to test the performance of various applications and services over a WAN link in the lab prior to live-deployment.

IPLinkSim™ can simulate all network impairment conditions of real world networks such as network latency, network delay variation (jitter), bandwidth, congestion, packet loss, packet FCS errors, packet bit errors and others.

RFC 2544 ITU-T Y.1564 standard compliance

Measure the performance of networks with series of sub tests - Throughput, latency, packet delay variation, frame loss and back-to-back tests with user-configurable packet headers.

Conduct a single test to validate SLAs as per ITU-T Y.1564 standard. Up to 10 service profiles can be configured to emulate pre-defined data streams in round-trip mode.

  • Service Configuration Test: CIR, EIR and Traffic Policing
  • Service Performance Test: Several KPIs are measured simultaneously for multi streams, and Pass/Fail verdict declared to identify the QoS of the network.
   
VLAN, Q-in-Q tags, or MPLS Testing Smart Loopback

Enterprise networks using VLANs, Q-in-Q for traffic prioritization and classification. With PacketExpert™, you can emulate Ethernet traffic with stacked VLAN (Q-in-Q) and stacked MPLS (supports up to 3) configurations.

PacketExpert™ supports Layer-wise loopback as well as Smart Loopback. Application of smart loopback (auto layer detection) for the incoming traffic allows you to verify if the frames are conforming to Ethernet addressing rules.

   
Record and Playback Platforms

PacketExpert™ is designed to work as a Wirespeed Ethernet Tap, and as a High-Precision Wirespeed Traffic Generator over optical or electrical interfaces with support for up to 1 Gbps. It supports all the features of high-end taps in a portable unit providing mobility and storage capacity to reach any point in the network.
