Description

Open vSwitch is a high-quality, multilayer virtual switch that operates under the open-source Apache 2.0 license. It is specifically engineered to facilitate extensive network automation through programming extensions, while still accommodating standard management interfaces and protocols such as NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, and 802.1ag. Additionally, it is built to allow distribution across various physical servers, akin to VMware's vNetwork distributed vSwitch or Cisco's Nexus 1000V. Open vSwitch is implemented in numerous products and is utilized in many substantial production environments, some of which are extraordinarily large. Each stable version undergoes rigorous testing, including a regression suite that consists of hundreds of system-level tests and thousands of unit tests. Furthermore, alongside OVS, the Open vSwitch community actively develops the OVN project, which enhances OVS by providing native support for virtual network abstractions, such as virtual L2 and L3 overlays and security groups. This commitment to continuous improvement ensures that Open vSwitch remains a robust solution for network virtualization in diverse settings.

Description

Flannel serves as a specialized virtual networking layer tailored for containers. In the context of the OpenShift Container Platform, it can be utilized for container networking as an alternative to the standard software-defined networking (SDN) components. This approach is particularly advantageous when deploying OpenShift within a cloud environment that also employs SDN solutions, like OpenStack, allowing for the avoidance of double packet encapsulation across both systems. Each flanneld agent transmits this information to a centralized etcd store, enabling other agents on different hosts to effectively route packets to various containers within the flannel network. Additionally, the accompanying diagram showcases the architecture and the data flow involved in facilitating communication between containers over a flannel network. This setup enhances overall network efficiency and simplifies container management in complex environments.
