Telecoms: Important step to better network performance

16.10.2002


Today, Eurescom, Spirent Communications, and BTexact Technologies announced the completion of a test that confirms the feasibility of performance management for IP Quality of Service (QoS) using Multiprotocol Label Switching (MPLS).



As a result of this test, service providers will be able to employ a simplified methodology for identifying the location of performance problems across multiple operator networks, and for verifying their capability to capture performance information at various classes of service. "This is an important achievement in making multiple operator networks more efficient," underlined Eurescom project manager Anastasius Gavras.

The test, part of Eurescom project P1106 on `E-commerce Impacts on Service and Network Operations and Management`, arose from an increasing need within the service provider community for improved network-performance visibility across the entire service delivery chain. For many applications, a subscriber`s traffic may traverse the networks of several providers in order to reach its destination.


Because traditional performance management tools can only monitor single networks, it used to be nearly impossible to determine which provider`s network is causing a problem when the subscriber experiences performance issues. However, the solutions defined and implemented within this test offer providers a model for collecting and correlating performance information not only within a given domain, but between domains as well. This "end-to-end" visibility enables providers for the first time to positively isolate performance problems with carrier-class speed, accuracy and efficiency.

"Providers have told us how important it is to feel confident their network-wide service assurance strategy can keep up with the accelerating migration to IP-based services," said Jim Schleckser, President of Spirent`s Service Assurance - Broadband business unit. "The Eurescom test project is positive proof that our end-to-end service assurance approach is ready today to meet the real-world deployment challenges of multi-vendor, multi-service, carrier-class networks."

Philip Wilmot, Senior IP Data Analyst, Next Generation Networks, IP Measurement and Data Analysis for BTexact, added, "Vital to the success of this effort was Perform`s ability to accurately report performance information for the various service classes. When impairments were injected into the test network, Perform was able to report the location and the impact of those impairments."

The test network - employed by Spirent and BTexact, and supported by Eurescom - consisted of two MPLS-based network domains, each running multiple service classes. Metrics used to measure QoS performance included one-way transfer delay, one-way delay variation, loss ratio, error ratio, and packet discard.

These measurements were taken from test probes and network elements provided by the participants; featured Spirent Communications products included their Smartbits traffic generation system, qScope 4000 test probes, IPWave impairment generation tool, and Perform OSS for performance and SLA management, while BTexact provided label edge and switching routers.

Under this testing, Perform`s role was to identify incidences when policing and discard was occurring due to traffic exceeding a threshold, as well as performance for each network domain and service class. This role took advantage of Perform`s ability to capture and report on a variety of metrics at different points in the end-to-end flow of subscriber traffic - an essential step in isolating performance issues in a multi-carrier, multi-vendor environment.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
