Transforming Enterprise Communications Infrastructure
Open unified communications and collaboration platforms can enable companies to evolve their legacy patchwork deployments.

We did several podcasts describing how one could get stellar packet forwarding performance on x86 servers reimplementing the whole forwarding stack outside of kernel (Snabb Switch) or bypassing the Linux kernel and moving the packet processing into userspace (PF_Ring).
Now let’s see if it’s possible to improve the Linux kernel forwarding performance. Thomas Graf, one of the authors of Cilium claims it can be done and explained the intricate details in Episode 64 of Software Gone Wild.

Technically, RESTCONF isn’t officially supported or even seen in the CLI to enable it, but more on that later.
When APIs are model driven, the model is the source of truth. If done right, all API documentation and configuration validation could occur using tooling built directly from the models. YANG is the leading data modeling language and as such, all API requests using RESTCONF/NETCONF are directly modeled from the YANG models IOS XE supports. For this post, we’ll just say the models can easily be represented as JSON k/v pairs or XML documents. We’ll cover YANG in more detail in a future post.
You can directly access the NETCONF server on IOS XE using the following SSH command (or equivalent from a SSH client).
The NETCONF server is a SSH sub-system.
$ ssh -p 830 ntc@csr1kv -s netconf
