thought of as being connected by virtual or logical links, each of which corresponds to a path, perhaps through your physical links, in the underlying network. for example, distributed systems such as peer-to-peer networks and client-server applications are overlay networks because their nodes run on top of the Internet. the Internet was originally built as an overlay upon the telephone network, while today (through the advent of VoIP), the telephone network is increasingly turning into an over

network. Although the three-tier network configuration is complex, it can be deployed automatically through the Controller. As long as the port of the network device is connected through a cable, all network configurations are automatically deployed. For example, in a VXLAN network, as long as the network device is configured with a route to connect to the Controller, the interface address is connected, and the Controller automatically sends a

Overlay NetworkOverlay network is a new data format that encapsulates two beginning text over an IP message without altering the existing network infrastructure, through some kind of protocol communication.This will not only take full advantage of the mature IP routing protocol process data distribution, but also in the overlay technology, the use of extended isolated identity bits, can break the VLAN 4000 number limit,Support up to 16M users, and when necessary, can convert broadcast traffic to

", "Subnetlen": 24, "Backend": { ' Type ': ' Vxlan ' } } Network defines the IP pool for this network as 10.2.0.0/16. Subnetlen Specifies that each host is assigned a subnet size of 24 bits, that is, 10.2.x.0/24. Backend for Vxlan, that is, between the host through the Vxlan communication, we will also discuss the HOST-GW later. Save Configuration to Etcd:Etcdctl

Network components include:1,vsphere Standard Switch , responsible for managing the virtual machine traffic. Must be managed separately on each ESXi host.2.vsphere Distributed Switch , which manages the traffic of virtual machines and Vmkernel, is shared and managed by ESXi hosts and clusters in a data center. The distributed switch abbreviation is VDS.3, Port/port group , is a logical object of Vswintch, a virtual switch can contain either a Vmkernel port or a virtual machine port group. Distri

OpenvSwitch enables interconnection between Docker containers and hosts 1. Introduction to OpenvSwitch Open vSwitch (OVS) is a virtual switch dominated by Nicira Networks that runs on a virtualization platform (such as KVM and Xen. On the virtualization platform, OVS can provide a layer-2 switching function for dynamically changing endpoints to control access policies, network isolation, and traffic monitoring in virtual networks. The main implementation code is the portable C code. It aims to e

In the previous section we discussed the issues that ML2 Plugin solved, and this section will continue to examine the architecture of ML2.ML2 abstracts and models the two-tier network, introducing the type driver and Mechansim driver.These two classes of driver decouple the network type (type) supported by Neutron and the mechanism for accessing these network types (mechanism), which results in a very good elasticity, easy expansion, and flexibility to support a variety of type and mechanism.Typ

supported by Neutron has a corresponding ML2 type driver. Type driver is responsible for maintaining the status of the network type, performing validation, creating networks, and so on. The network types supported by ML2 include local, flat, VLAN, Vxlan, and GRE. We'll discuss each type in detail in a later chapter.Mechansim DriverEach network mechanism supported by Neutron has a corresponding ML2 Mechansim driver. Mechanism driver is responsible for

Docker weave Network Weave implements an overlay network between docker hosts. It uses industry-standard vxlan encapsulation and UDP-based transmission, which can also be encrypted. Weave net creates a virtual network that connects multiple docker hosts. Similar to an Ethernet switch, all containers are connected to this network and communicate with each other. Weave net is composed of multiple peers. The weave router runs a user space process on diff

Tags: OpenStack network open source Neutron Virtual SwitchNow, when it comes to virtual switches, it's common to think of using open vswitch as a virtual switch because both individuals and businesses that support open vswitch want an open model to integrate their services into OpenStack. The open Vswitch community has done a lot of work to improve the position of open vswitch as the primary virtual switch. The community expects open vswitch to provide all the best possible switching services wh

Many new and recommended protocols have emerged for how to optimize the data center Ethernet and support its provision of server virtualization. Some of the protocols aim to achieve network virtualization by creating multiple virtual Ethernet networks that can share the same physical infrastructure. The sharing method is similar to that of multiple virtual machines sharing the same physical server. Most protocols applicable to network virtualization basically use encapsulation and tunneling tech
