Huawei Unveils Open Source DMM Project That Redesigns the Protocol Stack Container in Networking

At the 2018 Open Networking Summit North America, Huawei introduced the new Dual Modes, Multi-Protocols, Multi-Instances (DMM) open source project—a protocol stack framework—which elevates different protocol stacks for networking application developers. DMM is a Fast Data Project and a part of the community, which is tailored for open source software and aims to provide high-performance networking solutions. Leveraging Huawei’s expertise in providing cost-effective network solutions to customers, DMM will make it possible to use diverse protocol stacks for different apps, as well as simplify the process of developing a new protocol stack. This new framework will provide the enterprise industry with a more open, pluralistic, and reliable networking solution.

Linux Foundation and community participants in the DMM Fast Data project gathered at the Open Networking Summit North America in Los Angeles.

 In today’s open networking world, new network applications are constantly emerging, and need diverse network requirements ranging from QOS & SLA to transport protocol. Until now, most server applications used the Linux kernel stack. Even with the notable progress made thus far with the Linux kernel stack, today’s applications call for protocols that provide a strong performance guarantee. For instance, TCP protocol often inhibits performance as congestion leads to low link utilization. Amidst growing concerns surrounding network security protocol, a one-size-fits-all method is no longer realistic in today’s ecosystem. The new DMM project makes it possible to elevate different protocols for apps in a single host as well as within one app, while reducing overall development, operational, and maintenance costs.

The first version of DMM with will be released in April and will include a common stack API framework and an interface document. Moving forward, DMM will try to integrate other stacks, such as ‘f-stack’ and VPP communication library in addition to improving the performance and transparency of the frame layer.

“Huawei wants to establish an ecosystem for today’s variety of application and protocol stacks. Today’s ecosystem demonstrates a clear need for diversity. App users will benefit from this platform and will be able to apply it to their app scenarios without worrying about the stack choice. App developers will also be able to use different sockets to drive different stacks in one app,” said Chenxi Wang, VP Network Strategy and Ecosystem, Huawei. “For Huawei, the next generation of high-throughput/low-latency solutions will also benefit from this plug-and-play system. This solution will bring a new experience specifically for app and stack developers.”

“We are pleased to welcome Huawei’s DMM project into the ecosystem,” said Arpit Joshipura, GM of Networking and Orchestration, The Linux Foundation. “As networking hits Harmonization 2.0, it’s projects like DMM – which improves and redesigns how protocol stacks are used and developed – that further integrate container networking.”
