The Open Networking Foundation’s OpenNG-B810 specification has emerged as a focal point in the ongoing debate over how next-generation networking should evolve. While its proponents argue it offers a scalable, modular approach to cloud-native infrastructure, critics question its practicality, vendor lock-in risks, and whether it truly delivers on its promises of agility. The specification, which aims to standardise how cloud services interact with underlying network functions, has sparked both enthusiasm and scepticism among operators, developers, and industry watchers alike. Its implications stretch beyond technical architecture into broader debates about vendor neutrality, interoperability, and the future of cloud-native networking.
The B810 framework is designed to address the fragmentation of modern networking stacks, where disparate components—such as containers, microservices, and edge computing—often struggle to communicate efficiently. By introducing a standardised interface for network functions, OpenNG claims to eliminate the need for proprietary middleware, reducing complexity and enabling seamless integration across hybrid and multi-cloud environments. Yet, its adoption has been met with hesitation, particularly among enterprises relying on mature, vendor-supported solutions like Cisco’s ACI or VMware’s NSX. The question remains: can OpenNG-B810 truly bridge the gap between abstraction and reality, or is it another example of a well-intentioned but ultimately impractical standard?
Technical Foundations: What’s Inside the B810 Specification?
The OpenNG-B810 specification builds on the Open Networking Foundation’s (ONF) broader vision for software-defined networking (SDN), but with a sharper focus on cloud-native workloads. At its core, it defines a lightweight, RESTful API layer that sits between application services and underlying network infrastructure. This abstraction layer allows developers to treat network functions—such as load balancing, security policies, or traffic steering—as first-class citizens, much like containers or Kubernetes pods. The specification mandates support for standardised control planes, ensuring that network functions can be dynamically provisioned, scaled, and managed without deep vendor-specific knowledge.
One of the most contentious aspects of B810 is its emphasis on “network functions as code” (NFVC). Unlike traditional network virtualisation, where functions are often tied to specific hardware or proprietary software stacks, B810 encourages operators to treat network functions as software components that can be deployed, updated, and versioned like any other application. This approach aligns with the principles of DevOps and site reliability engineering (SRE), but it also raises concerns about operational complexity. For instance, managing a fleet of network functions across multiple clouds could require new tools for monitoring, logging, and troubleshooting—tools that may not yet exist or may be underdeveloped.
The Business Case: Why Companies Are (or Aren’t) Betting on OpenNG-B810
The adoption of OpenNG-B810 has been uneven, with early adopters including cloud providers like AWS and Google Cloud, as well as startups focused on edge computing. AWS, for example, has integrated B810-compatible network functions into its own services, allowing customers to deploy them alongside other AWS offerings without needing to build custom solutions. Meanwhile, Google Cloud has partnered with ONF to demonstrate how B810 can simplify multi-cloud networking for hybrid workloads. These moves suggest that OpenNG-B810 is gaining traction where it aligns with existing cloud strategies.
However, resistance persists among traditional networking vendors and enterprises that have invested heavily in proprietary solutions. Cisco, for instance, has not yet committed to full B810 compatibility, arguing that its own SD-WAN and ACI platforms offer superior performance and reliability for enterprise-grade deployments. Similarly, VMware’s NSX has been a cornerstone of many enterprises’ networking strategies, and its integration with B810 would require significant rework. The result is a fragmented market where OpenNG-B810 remains a niche option for organisations prioritising cloud-native flexibility over legacy compatibility.
- OpenNG-B810 defines a standardised API layer for cloud-native network functions, reducing reliance on vendor-specific middleware.
- Adoption has been fastest among cloud providers (AWS, Google Cloud) and edge computing startups, with enterprise adoption lagging.
- Critics argue B810 risks increasing operational complexity without delivering measurable performance gains over existing SDN solutions.
- The specification mandates support for dynamic provisioning of network functions, enabling seamless scaling in hybrid multi-cloud environments.
- Cisco and VMware remain largely unsupportive, citing better performance in their proprietary networking stacks for enterprise workloads.
- Early pilot deployments show potential for reducing cloud networking costs by eliminating proprietary middleware dependencies.
The Future: Will OpenNG-B810 Replace—or Coexist With—Existing Standards?
The trajectory of OpenNG-B810 will depend on several key factors, including its ability to attract broader vendor support, its performance in real-world deployments, and whether it can address the operational pain points that have historically limited SDN adoption. If successful, it could become the de facto standard for cloud-native networking, displacing older models like OpenFlow or Cisco’s ACI. But if it fails to deliver on promises of simplicity and interoperability, it may remain a curiosity rather than a mainstream solution.
A critical test will come in the coming years as enterprises migrate more workloads to the cloud and edge. Will OpenNG-B810 prove that abstraction can be both flexible and efficient, or will it be another example of a standard that overpromises and underdelivers? The answer could shape the future of networking for decades to come, making it a topic worth watching closely.
