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.

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. Plugins can be either included in the processing graph, or they can be built outside the source tree and become an individual component in your build. Furthermore, this separation of plugins makes crashes a matter of a simple process restart, which does not require your whole build to be restarted because of one plugin failure. For a full list of features, please visit the official Vector Package Processing Wiki. You can also check our previous installments on VPP integration.

This approach ensures that cache hits will be maximized.

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. The VPP platform consists of a set of nodes in a directed graph called a packet processing graph.

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. Make sure your file looks like the following. You can now boot up and access your virtual machine.

After setting the route, you can ping from csp2s22c03 to net2s22c05 , and vice versa. Using kernel IP forwarding, iperf3 shows the network bandwidth is about 8. For example, the GbE interfaces are ensf0 and ensf1. With scalar packet processing, instructions in the instruction cache are constantly replaced by new ones—they need to be taken from the main memory much more often, which degrades efficiency of the overall packet processing. On net2s22c05, TRex is used to generate both client and server-side traffic. In our case, the data is packet headers, while the instructions are operations defined in the vertices of our processing graph that should be performed on these headers. VPP can be used as a standalone product or as an extended data plane product. First, disable kernel IP forward in csp2s22c03 to ensure the host cannot use kernel forwarding all the settings in net2s22c05 and csp2s22c04 remain unchanged :. We will continue exploring the Binary API in the next part of our series. The VPP platform consists of a set of nodes in a directed graph called a packet processing graph. VPP is open source high-performance packet processing software.

What is VPP? VPP is the core technology behind the FD.

Each node provides a specific network function to packets, and each directed edge indicates the next network function that will handle packets. First, disable kernel IP forward in csp2s22c03 to ensure the host cannot use kernel forwarding all the settings in net2s22c05 and csp2s22c04 remain unchanged :. Current trends tracked and packaged in a series of articles to give you the ID At a minimum, you should install the VPP, vpp-lib, and vpp-plugins packages. At this point VPP is operational. Only the setup on net2s22c05 is modified slightly to run TRex preconfigured traffic files. We install them on the machine csp2s22c03 :. In the first two examples, the iperf3 tool is used to generate traffic, and in the last two examples the TRex Realistic Traffic Generator is used. Observe that the average vector per node is 6. VPP is open source high-performance packet processing software. The next node takes the frame of packets, processes them based on the functionality it provides, passes the frame to the next node, and so on. 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. Developed, tested, commercially-packaged and supported by Netgate. Instead of processing one packet at a time as the kernel does, the first node in the packet processing graph polls for a burst of incoming packets from a network interface; it collects similar packets into a frame or vector , and passes the frame to the next node indicated by the directed edge.
