Test Your VoIP Network With diversifEye

Shenick Network Systems, Ltd., headquartered in Dublin, Ireland, is a provider of IP
communications test and performance monitoring systems, enabling converged IP network
service providers to test and monitor the complete service delivery life cycle from the
laboratory to live service deployment.

Shenick is named after an island situated off the east coast of Ireland, about ten
miles north of Dublin. The castle situated on Shenick Island, known as a Martello Tower,
was built in the early 19th century during the Napoleonic era. The purpose of the tower
was to warn of an invasion from the sea. The Martello towers are situated all along the
east coastline of Ireland and within line of sight of each other. The early warning
system at the time involved lighting a fire on the top of the castle to signal other
towers along the coastal defense line.

The modern day Shenick Network Systems no longer lights signal fires to warn of
approaching network threats, but instead develops products that address next-generation
converged network and application performance issues for IPTV, Video on Demand (VoD),
Triple Play, IMS, Peer to Peer (P2P), Metro Ethernet, IPv4/IPv6 hybrid, and other network

Shenick commenced operations in 2000 in Dublin, and has since expanded into a Silicon
Valley office in Burlingame, California, and other offices in Germany and Singapore.

The company was recognized in September 2008 with a Global Technology Innovation
from Frost and Sullivan for their deep packet inspection test equipment, and
their technology for Internet-based application traffic control, shaping, and network

Shenick has developed two key network management solutions that support converged
networks. The diversifEye system is a per-flow converged IP network test system
that is offered to network equipment manufacturers, service providers, large enterprises,
and governments that need to assess network performance, quality of service and quality
of experience. The servicEye system is designed to support IP Television (IPTV)
deployments, providing end-to-end passive and active monitoring capabilities that can
scale to thousands of IPTV channels.

The diversifEye system consists of a fully integrated, highly scalable software and
hardware platform. The standard software package supports both voice and video media
analysis, including VoIP, VoD, and multicast IPTV. The software suite has the
capabilities to test at OSI Layers 2 through 7, including applications that are enabled
for either IPv4 or IPv6.

The system is shipped with a complete range of software modules and sample test cases
covering all application scenarios, and also includes a GUI client that offers full
automation and batch testing functions through a scripting interface. Three different
hardware platforms are available, all designed on a 19 inch rack mountable chassis, that
support stateful traffic emulation from 10 Mbps to 10 Gbps rates. Applications for the
system include:

  • VoIP: emulating real multimedia SIP/RTP calls with voice and video streams,
    with emulation support for both the client side (User Agent Client, or UAC), and the
    server server side (User Agent Server, or UAS). The system can determine loss, delay,
    and jitter along with mean opinion score, active PESQ and passive R-factor testing
    (see Figure 1).
  • IMS: Emulate SIP-based access scenarios and data over mobile applications,
    and emulate multiple IP services and applications across a variety of network access
    points (xDSL, Cable Modem Termination System (CMTS), FTTx, etc.).
  • Traffic Management: test traffic shaping, policing and service management
    systems with high performance, per-application, flow emulation. In addition, determine
    the cause and effect of peer-to-peer traffic on sensitive IPTV and VoIP
  • IPTV and VoD: determine QoE in real time on multicast IPTV streams and
    peripheral services; streaming performance analysis for Video On Demand, both stand
    alone and in the presence of VoIP and other Data Applications; plus conduct video
    quality analysis.
  • Application Server: emulate and conduct analysis of QoS and QoE for millions
    of ‘internet users in a box’, and concurrently generate mixed application flows such as
    HTTP, FTP, SMTP, streaming, multicast, etc.
  • Security: Determine limitations under normal operation and/or attack
    conditions. Concurrently generate both regular traffic, (e.g. a typical IP application
    mix of HTTP, FTP, VoIP, email, streaming, multicast video, and P2P) and attack traffic
    (e.g DDoS, Virus, Worms, and Spam) to determine effects on network performance.

In addition, diversifEye allows users to easily generate fully automated reports and
statistics, offering both real time and offline processing of results both during testing
and post analysis. Users have the ability to generate reports in a number of formats in
both graphical and tabular formats (see Figure 2).
