Ixia Helps Bring 1588v2 and SyncE Timing Protocols to Carrier Ethernet Mobile Backhaul

Switching to Ethernet-Based Service Delivery Lowers Carrier Costs and Enables Flexible Capacity Upgrades

CALABASAS, CA--(Marketwire - September 20, 2010) - Ixia (NASDAQ: XXIA), a leading, global provider of converged IP network test solutions, today announced that the latest version of its Carrier Ethernet testing solution now validates large-scale IEEE 1588v2 and SyncE timing synchronization technologies essential for mobile backhaul transport over Carrier Ethernet-based networks. Ixia will demonstrate its timing test solution at the Carrier Ethernet World Congress (CEWC) 2010 event taking place September 20th - 23rd in Warsaw, Poland.

Carrier Ethernet over IP has emerged as a cost-effective alternative to legacy TDM networks for flexibly handling bandwidth-hungry data traffic over mobile backhaul networks. However, Carrier Ethernet must satisfy the strict timing requirements of 2.5/3G wireless mobile backhaul. IEEE 1588v2 and Synchronization Ethernet (SyncE) technologies can be deployed separately or in conjunction across mobile backhaul network devices to provide the timing accuracy required for voice and other time-sensitive applications. As carriers scale network traffic, there is a real risk to the operation and stability of the timing protocols themselves that can result in missed call handovers, frequency drift, and even network downtime.

Ixia's comprehensive Ethernet Mobile Backhaul test solution includes conformance, functional, interoperability, and performance testing of both IEEE 1588v2 and SyncE implementations. Ixia's testing solutions emulate both master and slave clocks as well as the numerous protocols and traffic types typically carried over a mobile backhaul network. This multi-dimensional test strategy empowers service providers to create network conditions in a controlled lab environment so each chip, device, or multi-device system can be tested at scale in a reliable and repeatable manner. By scaling the number of emulated slave clocks and rate of timing protocol messages, service providers can evaluate the tradeoffs between timing performance and scalability -- critical for network capacity planning and service verification.

Key Facts:

  • According to Infonetics' recent survey of Global Service Providers, 100% of respondents claimed to be deploying IP/Ethernet backhaul in 2010. 65% of service providers plan to move to a single IP/Ethernet backhaul.
  • SyncE and/or IEEE 1588v2 technology can be used to synchronize clock frequency across devices in the Ethernet backhaul network and significantly improves clock accuracy and stability to satisfy timing requirements of supporting mobile voice subscribers (i.e., from +-100ppm (parts per million) to +-4.6ppm using SyncE).
  • Ixia accelerates Ethernet-based mobile backhaul adoption and migration by providing a comprehensive testing solution that emulates link OAM and service OAM protocols, tests both IEEE 1588v2 and ITU-T Sync-E Ethernet synchronization protocols and run Carrier Ethernet data plane capacity tests, verify QoS handling algorithms, and characterize maintenance and fault handling recovery of the carrier network.

Supporting Quotes:

  • "Ixia's ability to validate timing protocol implementations' performance in the context of other network protocols and traffic gives carriers the confidence to deploy timing solutions, such as our TimeProvider 5000 Grandmaster Clock," said Eric Colard, Head of Strategic Alliances at Symmetricom," said Eric Colard, Head of Strategic Alliances at Symmetricom.

  • "One of the largest barriers preventing operators from moving to IP/Ethernet backhaul is the timing and synchronization required for mobile voice traffic. Now that IEEE 1588 v2 and Synchronous Ethernet have solved the technology issues, service providers need to validate at deployment that the timing accuracy and frequency synchronization is reliable for each particular backhaul link," stated Michael Howard, Principal Analyst at Infonetics Research. "Ixia's products are designed to help mobile operators and backhaul transport providers in establishing that reliability."

  •  "Carriers have major incentives to replace TDM-based circuits with Ethernet-based backhaul networks in order to capitalize on associated cost savings and ability, and better support the growing number of subscribers and associated bandwidth requirements," said Tara Van Unen, Sr. Manager, Market Development at Ixia. "Ixia's timing solution allows carriers and mobile operators to verify that their Carrier Ethernet deployments meet the timing requirements necessary for an accurate and dependable infrastructure."
