Spirent Debuts HTTP/3 Assessment Capabilities

Spirent Communications announced the immediate availability of HTTP/3 testing capabilities for its network load testing solution, Spirent Avalanche.

HTTP/3 is the evolving standard for the next generation secure and high-performance web access application protocol, and Spirent offers a solution with full testing support for Internet Engineering Task Force (IETF) ratification.

A major revision of the Hypertext Transfer Protocol (HTTP), HTTP/3 is the technology that underpins the transfer of information on the web. By offering this new functionality in its popular Avalanche solution, Spirent is enabling customers to test and validate primary HTTP/3 functionality, and conduct blended high-scale performance tests across all common implementations of HTTP, including HTTP 1.0/1.1 and HTTP/2.

“With evolving protocols and web services, HTTP/3 ushers in new performance and security capabilities as the backbone of user’s interaction with web applications,” said Aniket Khosla, VP of Product Management at Spirent. “Even when standards have not yet been fully set on specific protocols, we have always felt it is vital to provide customers with effective testing solutions as early as possible, because this allows them to stay ahead of the curve and better prepare for new application implementations and integrations.”

As the first vendor to offer a solution with HTTP/3 testing support based on IETF drafts 29 and 32, Spirent is committed to quickly updating its HTTP/3 implementation as the standard continues to evolve towards formal ratification. HTTP/3 testing and validation is available on all supported Avalanche platforms, from entry-level solutions, to Spirent’s high-capacity and carrier-class C200 appliance, which provides multi-100Gbps of testing capacity. Additionally, Avalanche can be used to test network services in virtual and cloud environments, such as ESXi, KVM, AWS, Azure and GCP, maximizing HTTP/3 test case coverage.

Avalanche’s Layer 4-7 testing solution offers capacity, security and performance testing for network infrastructures, cloud and virtual environments, Web Application infrastructures and media services to ensure Quality of Service (QoS) and Quality of Experience (QoE) for customers. It also pinpoints network capacity with the highest performing Layer 4-7 traffic generation capability available from 1Gbps to >100Gbps.
