Welcome to our new series on how to build and program FD. Single packet processing and high latency were a common occurrence in the older, scalar processing approach, which VPP aims to make ob sole te. This four-part series will include the following features, with the ultimate goal on getting to know your VPP framework and adapting it to your network:. T he main advantages are:. The principle of VPP is, that you can plugin a new graph node, adapt it to your networks purposes and run it right off the bat. Including a new plugin does not mean, you need to change your core-code with each new addition.

In this article, I will take a closer look at what distinguishes this technology from others and how helpful it can be in meeting the demand for efficient network solutions. Regardless of the specific hardware or software implementation at the dataplane level, packet processing can be generally described as a sequence of operations that are performed on packets. This can be represented as a graph in which each vertex corresponds to an operation. For this purpose, we will use an illustrative example see Figure 1 below. Imagine a very simple packet processing graph with only three vertices, with each representing an action performed on a different type of protocol header. First, let's take a look at what the standard approach to packet processing will look like. When the first packet enters the dataplane, it will be processed through the entire graph, according to the established order. First, vertex 1 specific operations will be performed on the packet. Once completed, the actions appropriate to vertex 2 will be applied. Finally, the packet will be subjected to operations defined in the final vertex, 3, thus completing the processing. In each vertex, some specific operation will be performed on another header in the packet. All these steps will then be repeated for the second packet and then for all subsequent packets.

In this example we use only two systems, csp2s22c03 and net2s22c05, to run the TRex Realistic Traffic Generator.

Introduction This tutorial shows how to install the FD. VPP is open source high-performance packet processing software. DPDK provides fast packet processing libraries and user space drivers. It receives and send packets with a minimum number of CPU cycles by bypassing the kernel and using a user poll mode driver. VPP can be used as a standalone product or as an extended data plane product. This approach ensures that cache hits will be maximized.

This page has moved to the versioned documentation , please do all edits there. This tutorial is designed for you to be able to run it on a single Ubuntu It walks you through some very basic vpp senarios, with a focus on learning vpp commands, doing common actions, and being able to discover common things about the state of a running vpp. If you do not already have virtualbox on your laptop or if it is not up to date , please download and install it:. If you do not already have Vagrant on your laptop or if it is not up to date , please download it:. Please note, certain aspects of this tutorial require vpp Also, note that for this tutorial, you will need the vpp plugins as well.

It is intended to people with little experience of VPP. However, having followed e. Having a working Linux VPP environment. The easiest way to get it done is to install Vagrant and build a test image.

This process repeats until the last node gets the frame, processes all the packets in the frame based on the functionality it provides, and outputs them on a network interface. Refer to Figure 1 and Figure 2 for configuration diagrams. It leverages DPDK to run in user space. More from this author. In particular, it provides a whole set of tools for building software agents that allow you to control and manage CNFs. Also, four worker threads are selected and run on cores 2, 3, 22, and In the era of deployments based on NFV and cloud-native paradigms, any solution that offers not only the required functionality but also performance is certainly worth some attention. Using kernel IP forwarding, iperf3 shows the network bandwidth is about 8. For kernel forwarding, set Finally, the packet will be subjected to operations defined in the final vertex, 3, thus completing the processing. Figure 1 illustrates this configuration. This can be represented as a graph in which each vertex corresponds to an operation. In this section, four examples of running VPP are shown.

First, vertex 1 specific operations will be performed on the packet. The system csp2s22c03 , with VPP installed, is used to forward packets, and the systems csp2s22c04 and net2s22c05 are used to pass traffic. Finally, four examples using iperf3 and TRex were included, to show how VPP processes packets in batches. And then we can repeat this procedure for all of the other boards. Similarly, on net2s22c05 , we configure the system to have the address Single packet processing and high latency were a common occurrence in the older, scalar processing approach, which VPP aims to make ob sole te. CNI concerns itself only with network connectivity of containers and removing allocated resources when the container is deleted. This approach ensures that cache hits will be maximized. On csp2s22c03 , we configure the system to have the addresses How should this be done? VPP can be used on bare metal, virtual machines VMs , or containers.
