A10 pushes virtualized DDoS protection performance for 5G networks

A10 Networks is ready to begin shipping a software version of its Thunder Threat Protection System (TPS) solution, vThunder TPS, that provides 100 Gbps throughput in a single virtual appliance and can be expanded to 800 Gbps with eight-way clustering.

The virtualized solution can be used by operators to scale their DDoS defense when peak capacity is required. vThunder TPS is compact and efficient, allowing it to be deployed in next-generation mobile edge compute (MEC) environments, conserving space and power while providing powerful DDoS protection.

A10 Networks said the transition to 5G makes this even more critical as operators need to be able to ensure the availability of business services against the potential for large DDoS attacks, particularly during high-visibility times like global sporting events and seasonal shopping spikes. DDoS attacks will only increase in severity as operators expand services to support IoT-driven energy, agriculture, transportation, healthcare and manufacturing.

Key capabilities of vThunder TPS

  • Cloud-ready DDoS Defense: Customers are able to gain deployment and operational flexibility with DDoS defenses that support major private cloud platforms including KVM, VMware ESXi and Microsoft Hyper-V. A high-performance 100 Gbps virtual appliance can scale to 800 Gbps with eight-way clustering to meet the performance needs of 5G mobile operators and cloud providers.
  • Agility and Scalability: With A10’s FlexPool licensing, capacity can be scaled up in hours via license allocation rather than in weeks or months required for hardware purchasing, delivery and installation. Capacity can be scaled back down by reallocating licenses to other points of presence when intermittent demand subsides. A10’s subscription price model also provides lower start-up and upgrade costs.
  • Comprehensive Protection: When combined with the Orion 5G Security Suite, vThunder TPS provides high-performance DDoS detection and mitigation and protection against other threats across mobile and cloud network infrastructures.

U.S. Department of Justice charges Huawei under RICO act

The U.S. Department of Justice and the FBI are charging Huawei Technologies Co. Ltd. and two U.S. subsidiaries with conspiracy to violate the Racketeer Influenced and Corrupt Organizations Act (RICO).

A 16-count superseding indictment in federal court in Brooklyn, New York cites a long-running practice of using fraud and deception to misappropriate sophisticated technology from U.S. counterparts. The Department of Justice alleges that Huawei, and several of its subsidiaries, both in the U.S. and in the People’s Republic of China, misappropriated intellectual property, including from six U.S. technology companies, including intellectual property, trade secrets and copyrighted works, such as source code and user manuals for internet routers, antenna technology and robot testing technology.

The indictment states that as a result of this campaign to steal this technology and intellectual property, "Huawei was able to drastically cut its research and development costs and associated delays, giving the company a significant and unfair competitive advantage."

Department of Commerce issues 45-day extension for Huawei

The Bureau of Industry and Security (BIS) of the U.S. Department of Commerce extended a Temporary General License (TGL) for Huawei Technologies Co. Ltd. and its non-U.S. affiliates on the Entity List for an additional 45 days.

The Department of Commerce said the 45-day extension will prevent interruption of existing network communication systems in rural U.S. regions and permit global network security measures.  The TGL is intended to allow time for companies and persons to shift to alternative sources of equipment, software and technology (i.e., those not produced by Huawei or one of its listed affiliates). 


  •  In May 2019, the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce, first added Huawei and its affiliates to the Bureau’s Entity List. The reason given is that "Huawei is engaged in activities that are contrary to U.S. national security or foreign policy interest." For companies on the Entity List, a license must be issued by BIS for the sale or transfer of U.S. technology. A license may be denied if the sale or transfer would harm U.S. national security or foreign policy interests.

Spirent on 5G: What to expect in 2020

There is a rush to move past 5G Non-Standalone (NSA) to Standalone (SA) rollouts because it is a quicker path to revenue and profitability for carriers, according to a new report from Spirent Communications.  The “5G: What To Expect In 2020” report draws on the company’s expansive work with operators, network equipment manufacturers and device makers.

“2019 brought worldwide 5G Non-Standalone deployments but meaningful revenues were elusive as operators struggled to break out with market-defining services that could ignite consumer enthusiasm,” said Spirent head of 5G, Steve Douglas. “Spirent’s report goes behind the scenes of our 5G testing engagements to explore what went as planned, where there were stumbles and why the outlook is brightest as stakeholders evolve strategies to capitalize on emerging opportunities, especially in the enterprise.”

Key findings from Spirent’s “5G: What To Expect In 2020” report include:
  • 5G Standalone coming earlier than expected. There is a rush to move past Non-Standalone (NSA) to Standalone (SA) rollouts in an effort to capture revenues in industries like manufacturing, automotive, mobile gaming, manufacturing and beyond. Based on testing timetables, Spirent expects a slate of 5G SA deployments in the first half of 2020. 
  • Smartphone performance challenges extend beyond the device itself. 5G device performance pains stemmed from issues related to the vast number of antennas that must be packed into devices, but also challenges introduced by 5G New Radio, which was not tuned to exploit all capabilities defined within standards. The result sometimes produced performance that looked more like 4G LTE. 
  • Experiences were not optimized to wow consumers. In cases where 5G did deliver anticipated speeds, feature sets and apps were not optimized to take advantage of the speed and bandwidth, meaning consumers couldn’t discern a major experience difference. Spirent expects mobile gaming to be among the earliest consumer use case to capitalize on customized 5G performance boosts. 
  • Assurance now a requirement, not an afterthought. Spirent closed the year having kicked off the first nationwide North American 5G assurance deployment as operators seek to shore up network performance in a bid to deliver the robustness and reliability that will be demanded by enterprise customers.  
  • Some of 5G’s biggest advancements are happening underground. It is ultimately transport networks that will support the data deluge 5G is expected to attract. Significant investment is going toward assuring these networks won’t collapse under heavy demand, with expansive testing efforts underway right now.
