#UBUNTU NETMAP MANUAL#
In the rest of this (long) manual page we document various aspects of the netmap and VALEĪRCHITECTURE netmap supports raw packet I/O through a port, which can be connected to a physical Performance, netmap requires native support in device drivers. Kernel module, which also emulates the netmap API over standard drivers. All types of netmap ports and the VALE switch are implemented by a single Through a file descriptor and standard OS mechanisms such as select(2), poll(2), kqueue(2)Īnd epoll(7). Netmap supports both non-blocking I/O through ioctl(2), synchronization and blocking I/O Similarly, VALE switch instances and ports, netmap pipes and netmap monitors can be created dynamically, providing high speed packet I/Oīetween processes, virtual machines, NICs and the host stack. Userspace clients can dynamically switch NICs into netmap mode and send and receive raw

Without native netmap support can still use the API in emulated mode, which uses unmodifiedĭevice drivers and is 3-5 times faster than bpf(4) or raw sockets. Hardware) about 20 Mpps per core for VALE ports and over 100 Mpps for netmap pipes. Less than one core on 10 Gbit/s NICs 35-40 Mpps on 40 Gbit/s NICs (limited by the Using netmap on supported NICs reaches 14.88 million packets per second (Mpps) with much

With suitably fast hardware (NICs, PCIe buses, CPUs), packet I/O Order of magnitude faster than standard OS mechanisms (sockets, bpf, tun/tap interfaces,
#UBUNTU NETMAP SOFTWARE#
Implementing a very fast and modular in-kernel software switch/dataplane Ī shared memory packet transport channel Ī mechanism similar to bpf(4) to capture trafficĪll these netmap ports are accessed interchangeably with the same API, and are at least one To access individual queues of network interfaces It runs on FreeBSD Linux and some versions of Windows,Īnd supports a variety of netmap ports, including SYNOPSIS device netmap DESCRIPTION netmap is a framework for extremely fast and efficient packet I/O for userspace and kernelĬlients, and for Virtual Machines. It’s time to test, therefore start vmware network services.NAME netmap - a framework for fast packet I/O The second line: add_bridge_mapping enp5s0 2 The line add_bridge_mapping enp2s0 0 will define a custom bridge for vmnet 0, see below:Įnp2s0 0 = tells to vmware use the NIC enp2s0 as bridge on vmnet0. My system has 2 NICs and I want to set them as bridge.įirst of all, stop vmware services typing the following command. There are some files related to the configuration and two of them are related to the network:īoth are necessary to configure the network. The VMWare networking configuration is stored in the following folder on Ubuntu: Of course it was my first time configuring VMWare on text mode and I spend some time to understand. Until now I’ve used the VMware network configation tool to setup the network, but I cant do it anymore, there is only text mode available. I’m using a UBUNTU 16.04.2 server LTS, only text and found a situation when I’ve started a network configuration for 2 NICs. Unfortunately there is no good documents regarding the manual networking configuration for VMWARE Workstation 12.5.5, therefore I’ve decided explain a little bit. I few days ago I’ve started a new benchmark of VMWARE Server running on Linux no GUI (text only).
