Verification platform for Cisco's SRP
Ixia has announced the industry's most comprehensive performance analysis and traffic generation platform for verification of Cisco System's Spatial Reuse Protocol (SRP).
Ixia has announced the industry's most comprehensive performance analysis and traffic generation platform for verification of Cisco System's Spatial Reuse Protocol (SRP) SRP is used to build resilient packet ring (RPR) networks for next-generation native IP over optical metro and intra-point-of-presence (intra-POP) solutions

Clearly fused for vehicle current measurement
Klari-Fuse detects errors in automobile electronics with precise measurement of currents in vehicle fuse devices.
Ixia's performance analysis solution for SRP is implemented via its OC-48c Packet Over SONET interface Load Module (LMOC48).
The LMOC48 captures and analyses control messages that are exchanged between nodes on an SRP ring.
These messages are used to communicate the health, topology, and congestion status of the ring to network administrators.

Current transducers maintain accuracy
A new series of DC current transducers provides tighter accuracy to 1.0% full-scale for more stable operation over a wide temperature range from -40 to +85C.
Current transducers handle speedy waveforms
A new series of bidirectional current transducers is capable of accurately following extremely fast (DC and/or AC) current waveforms.
Ixia's unique product architecture, featuring extremely high port density and wire-speed performance, enables SRP modules to be inserted directly into a ring as a pass-through device without the need for additional hardware.
As a result, network equipment manufacturers and service providers will benefit from a more cost-effective and easier-to-implement means of developing, testing, and deploying SRP-based solutions.
Additionally, as Ixia's comprehensive solution requires less hardware, there are fewer potential points of failure.
"SRP provides efficient, high-speed optical internetworking connectivity for the next generation of network deployments, particularly in metropolitan area networks (MAN)", said Eran Karoly, vice president of marketing for Ixia.
"Our support for SRP underscores our commitment to providing traffic generation and analysis solutions that address the migration requirements of MAN operators moving from a traditional SONET infrastructure to a RPR-based solution".
"Ixia now provides service providers with a highly efficient tool for validating the enhanced scalability, reliability and ease of operations gained by deploying SRP-based, resilient packet ring solutions like Cisco's Dynamic Packet Transport", said Graeme Fraser, vice president and general manager, Metropolitan IP Access Business Unit, Cisco Systems.
SRP is a Cisco-developed MAC-layer protocol which enables IP routers to be connected directly to the optical ring topologies typically found in metro areas.
By combining the intelligence of IP routing with the bandwidth efficiencies of optical rings, SRP allows service providers to offer their customers new, value-added IP-based services such as Voice over IP or Virtual Private Networks through the metro gateway.
And because interconnecting routers directly to fibre instead of to legacy SONET equipment reduces network layers, SRP also cuts down on overhead costs and time to market.
SRP is incorporated into the offerings from multiple systems, software, silicon and test equipment vendors including Cisco's Dynamic Packet Transport or DPT product family.
DPT is the resilient packet ring market leader, deployed in more than 150 customer networks with nearly 10,000 ports shipped.
Cisco has submitted SRP, which is based on IETF informational RFC 2892 and is available license free, to the IEEE 802.17 Resilient Packet Ring (RPR) Working Group for consideration as the industry standard.
