# OpenContrail

OpenContrail represents Juniper Networks' venture into the open-source realm of network virtualization, complemented by its commercial counterpart known as Contrail.

## The Blueprint

The OpenContrail infrastructure primarily consists of two pivotal components:

* The **Controller** orchestrates the creation, control, and analytical operations for virtual networks.
* The **vRouter** facilitates distributed routing, eager to manage the establishment of virtual routers and networks, as well as the handling of data forwarding.

The vRouter notably operates in three distinct flavors:

* **Kernel vRouter**: Carries a resemblance to the OVS kernel module.
* **DPDK vRouter**: Mirrors the capabilities of ovs-dpdk.
* **Netronome Agilio Solution (a commercial product)**: Ready to support a trifecta of advanced networking technologies including DPDK, SR-IOV, and Express Virtio (XVIO).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kubernetes.feisky.xyz/en/extension/network/opencontrail.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
