Ixia Announced ITU-T G.709 Optical Transport Network (OTN) “XOTN” Test Solution


Ixia (NASDAQ: XXIA), the leading, global provider of higher speed Ethernet (HSE) test solutions, recently announced an optical transport network (OTN) test solution for 40 and 100 gigabit OTU3/4 rates. Ixia’s “XOTN” solution extends the company’s position as the foremost supplier of test solutions for HSE, as recently reported by Frost & Sullivan. Ixia’s XOTN solution meets the extraordinary performance and protocol scale test needs of evolving dynamic, packet-switched core transport networks, including advanced MPLS and MPLS-TP protocol implementations.

Ixia’s higher speed test solutions enable service providers and network equipment manufacturers (NEMs) to validate the performance and protocol scalability of higher speed network equipment – for both Ethernet and OTN – at 40G and 100G speeds. Ixia’s XOTN tests carrier-class core routers, switches, and multiservice provisioning platforms (MSPPs) that forward client-side traffic to core transport line equipment. This unique OTN solution, in conjunction with Ixia’s IxNetwork™ test application, provides a much-needed large-scale, multi-protocol network emulation that is coupled with sophisticated line-rate traffic generation. The solution addresses service providers’ requirements to validate service level agreement (SLAs) and resiliency over OTN networks, and to certify carrier-class routers with OTN interfaces. XOTN also addresses NEMs’ requirements to validate new router OTN line cards using IP, MPLS, and Ethernet traffic, and to validate Ethernet data mapping over OTN transport.

HSE helps service providers address the rapid bandwidth growth in data centers for short distance interconnects and some longer-reach metro networks, but is not suitable for long-haul transport networks. OTN, on the other hand, was designed for packet transport over long distances and is ideal for Ethernet, IP, and MPLS layer interconnects. OTN, initially fielded in the early 2000s, provides a flexible digital wrapper that encapsulates different types of traffic while adding the operations, accounting, and maintenance (OAM) capabilities required for carrier-grade delivery over 40G and 100G metro and long haul networks. Large-scale layer 2/3, MPLS, and VPN topologies are being deployed over OTN transport as it is being integrated with core routers for deployment on a regular basis. Ixia couples OTN and lower speed Ethernet interface technologies with the largest scale, full protocol emulation necessary for testing next-generation OTN-capable routers and switches, including IP, MPLS, and MPLS-TP protocol emulation.

Key Facts
  • Ixia’s XOTN test solution extends its existing Ixia K2 HSE 40GE and 100GE CFP MSA compatible load modules, providing realistic network protocol emulation and data path traffic for OTU3/4 capable devices.
  • XOTN conforms to ITU-T Recommendation G.709/Y.1331 and provides layer 1-3 testing.
  • XOTN operates with Ixia’s IxNetwork application, covering layer 2-3 protocols such as IP, Carrier Ethernet, MPLS, and MPLS-TP over OTN at full 40G OTU3 and 100G OTU4 line rates.
  • According to Frost & Sullivan, Ixia is the leading manufacturer of HSE 40/100GE test solutions. Ixia’s HSE interfaces provide full layer 1-7 testing of HSE devices and networks. CFP MSA interfaces are available for 40/100GE modules, and QSFP+ interfaces are available for 40GE modules.

“As OTN networks begin to fulfill the promise of 100G bandwidths nationwide, service providers must transport a variety of protocols and services across these networks at high scale,” said Vic Alston, senior vice president of product development at Ixia. “Ixia provides a compelling solution that combines lower-layer OTN features with the ability to realistically emulate large-scale routed networks moving media-rich traffic from such sites as Facebook, Netflix, and Pandora.”

“Varied mixes and types of traffic assault networks at higher volumes each day, yet traffic management and customer satisfaction remain huge necessities for operators,” said Michael Howard, co-founder and principal analyst at Infonetics Research. “OTN provides not just the bandwidth, but the monitoring needed for managing the quality of optical transport networks today. Ixia’s move into OTN is an inevitable consequence of these evolving network requirements.”
