Circuit Emulation Testing with Network
Emulators
TDM Solutions in a packet-based world
Despite the growth of Ethernet services, TDM still plays a significant
role in enterprise networks in the 21st century. Circuit Emulation Services
(CES) and Pseudowire Emulation (PWE) have emerged as methods for carrying
TDM circuits over a packet-switched network. There are many benefits and
applications for CES, all depending on the delivery of a low-delay, low-jitter
signal over Ethernet.
Does your solution:
* Provide the optimum buffer size to compensate for the Packet Delay Variation
found in Ethernet/MPLS networks without introducing unacceptable latency?
* Correct packet-sequence errors without affecting the user experience?
* Interpolate appropriate values for lost packets to minimize the impact
on voice/video quality?
The benefits of transporting TDM over Ethernet are compelling. Both CapEx
and OpEx required to support TDM services can be lowered, easing budget
pressure for customers and enabling a sustainable business model for carriers
to offer a full range of communications services. As a result, several
organizations are establishing standards for this technology, including
the IETF, the MEF, the MFA Forum and the ITU, to address encapsulation
of Nx64, T1, E1, T3, E3, OC-3, STM-1, OC-12 and STM-4 lines for transmission
across IP, MPLS and pure-Ethernet.
Anue Network Emulators excel at circuit emulation testing by enabling
you to emulate the packet network carrying CES with a high degree of precision
and repeatability.
Whether your application is backhaul for wireless transport, end-to-end
TDM services for enterprise, or TDM access with interworking between Ethernet,
Frame Relay and ATM, circuit emulation testing with Anue Systems can help
you address the questions that must be answered before your circuit emulation
or pseudowire solution is released on a live network.
With Anue Ethernet network emulation you can:
* Validate the performance of buffers by introducing Packet Delay Variation
and re-order with great precision and repeatability.
* Validate the performance and accuracy of carrying critical timing information
across a packet based network.
* Validate packet-loss-concealment algorithms by introducing packet loss
and re-order with great precision and repeatability.
* Validate the performance of protection fail-over features.
* Verify compliance of performance metrics reporting and status/alarm
indicators.
* Validate misconnection and malformed frame detection by modifying frame
information. (MEF8)
* Improve time-to-market by increasing circuit emulation testing efficiency
through Tcl automation.
* Develop and define new solutions by specifying performance metrics required
for service levels and SLAs.
Since 1997, Gillaspy Associates has built
a solid reputation for developing strong relationships with our customers
by providing quality solutions and ongoing support.
