Teledyne LeCroy's Protocol Analyzer adds PAM4 50G-400G Ethernet

Teledyne LeCroy introduced a trace capture and analysis solution for the 802.3cd and 802.3bs 50/100/200/400GE four-level pulse amplitude modulation (PAM4) Ethernet specifications.

The new capability, which is available as a license for the company's SierraNet T328 protocol analyzer, enables higher data rates and enhanced reliability for future-generation data centers and cloud-based services.

Teledyne LeCroy notes that PAM4 signals are more susceptible to errors in noisy environments. To reduce the error rate, systems negotiate transmission parameters that maximize signal quality at the receiver. PAM4 Systems designers are demanding the link-layer analysis capabilities to ensure the negotiation among components is effective.

The SierraNet T328 can now help identify and reduce link-interoperability problems between major fabric components such as switches, routers, network interface adapters, servers, and Network Attached Storage (NAS).

"By providing real-time trace capture, decode, and analysis of the auto-negotiation and link-training functions, the SierraNet T328 has become the de facto standard for high-speed protocol analysis in development, debug, and test applications," stated David J. Rodgers, Ethernet and SAN Product Line Manager at Teledyne LeCroy.

ADTRAN heads Broadband Forum’s Application-Level Traffic Generation Testing

ADTRAN is leading an initiative within the Broadband Forum that will leverage application-level traffic generation for advanced broadband testing.

The idea is to develop standardized testing of dynamically reconfigured virtualized services, which can challenge traditional methods of performance characterization.

The first project in the Application-level Traffic Generation for Advanced Broadband Testing Project Stream is expected to be completed in late 2018, with follow-on projects in early 2019. It will deliver on the following principals:

  • Define and specify a model for the generation of test traffic at the application level that emulates real-time domain behavior of multiple applications from multiple subscribers.
  • Create a reference implementation for use in test cases in Open Broadband Labs and in other test environments as developed by the Broadband Forum and other industry stakeholders.
  • Primarily address high-speed internet access for residential use. In a later phase, business applications could also be addressed.


“This initiative will benefit service providers, vendors and testing labs by fundamentally allowing them to manage the increasingly complex subscriber traffic on the network as application and service parameters change and evolve,” Broadband Forum CEO Robin Mersh said. “The project stream will have far-reaching positive effects on the entire industry and is why the Broadband Forum is championing it. ADTRAN’s domain experience in helping the industry transition to a more flexible, scalable and secure software-defined access network is certainly appreciated.”

“As carriers invest in upgrading the access infrastructure and look to leverage the service creation capabilities now available, it is critical that testing evolves to keep pace and ensure that the promises of software-defined access are realized,” ADTRAN Senior Staff Scientist and Project Stream Leader Ken Ko said. “ADTRAN has played an instrumental role in bringing this work forward and we look forward to collaborating with our peers within the Broadband Forum to advance this important work.”

Barefoot Tests its Switch Performance with Ixia IxNetwork + Novus

Network testing solutions provider Ixia announced that Barefoot Networks, developer of high-performance, programmable switch solutions, has chosen its 100 Gigabit Ethernet test solutions to validate the Tofino series of programmable switches launched in June last year.

Utilising the Ixia solutions, Barefoot will be able to ensure that its Tofino switches deliver the performance network operators demand, as well as test the functionality enabled by its programmable packet processing pipeline, for example new or custom protocols, in-band network telemetry and load balancing.

Barefoot's Tofino switches are based on technology that is designed to enable a fully programmable Ethernet switch that does not suffer a performance penalty to its 6.5 Tbit/s traffic processing capability. To validate the performance, scale and quality of these switches, Barefoot test engineers can use Ixia's IxNetwork and Novus 100 Gigabit Ethernet solutions to recreate real-life traffic patterns and load characteristics.

Ixia's IxNetwork offers a complete chip, device and network infrastructure test solution that can be used to validate Layer 2/3 performance, interoperability and functionality. Capable of analysing up to 4 million traffic flows simultaneously, IxNetwork is designed to provide enhanced real-time analysis and statistics. Featuring eight native QSP28 100 Gigabit Ethernet ports, the Ixia Novus load modules can generate terabytes of data to simulate real-world network traffic and Layer 2/3 protocols.

In combination, the Ixia solutions provide a test platform designed to enable full line-rate 100 Gigabit Ethernet evaluation of application-specific integrated circuit (ASIC) designs, field-programmable gate arrays (FPGAs) and hardware switch fabrics.

Recently at MWC, Barefoot Networks partnered with Netronome, a provider of intelligent networking solutions, to demonstrate a solution combining the Agilio CX SmartNIC platform and its Tofino P4-programmable switch to deliver precise, real-time network telemetry data required to detect, root-cause and resolve network problems.

The joint solution showed how a DevOps approach can be used to triangulate performance issues to VMs and NICs in servers or network switches and thereby enable the detection of poorly performing virtual network functions (VNFs) in service chains.
