Internal network virtualization configures a single system with software containers, such as Xen hypervisor control programs, or pseudo-interfaces, such as a VNIC, to emulate a physical network with software. This can improve a single system's efficiency by isolating applications to separate containers or pseudo-interfaces.
The Crossbow project software, combined with next generation network interfaces like xge and bge, enable network virtualization and resource control for a single system. By combining VNICs with features such as exclusive IP zones or the Sun xVM hypervisor, system administrators can run applications on separate virtual machines to improve performance and provide security.
Virtualized network functions (VNFs) are software implementations of network functions that can be deployed on a network functions virtualization infrastructure (NFVI). [10] Network functions virtualization infrastructure (NFVI) is the totality of all hardware and software components that build the environment where NFVs are deployed.
Twisted is an event-driven network programming framework written in Python and licensed under the MIT License.. Twisted projects variously support TCP, UDP, SSL/TLS, IP multicast, Unix domain sockets, many protocols (including HTTP, XMPP, NNTP, IMAP, SSH, IRC, FTP, and others), and much more.
Initially, network virtualization only involved the separation of the control plane and the forwarding plane (management and packet transmission) within networking devices like switches. This has shifted to include the totality of virtualizing a network, including how the network is programmed, administered, and deployed, be it hardware ...
Salt (sometimes referred to as SaltStack) is a Python-based, open-source software for event-driven IT automation, remote task execution, and configuration management. Supporting the " infrastructure as code " approach to data center system and network deployment and management, configuration automation, SecOps orchestration, vulnerability ...
OVN is a network virtualization platform that separates the physical network topology from the logical one. [2] Users are able to connect virtual and physical interfaces with logical switches and routers, regardless of the underlying physical topology. Users are also able to define security policies and load-balancing to these logical instances.
Open vSwitch deployed as a cross-server virtual network switch, transparently distributed across multiple physical servers.[3]Open vSwitch is a software implementation of a virtual multilayer network switch, designed to enable effective network automation through programmatic extensions, while supporting standard management interfaces and protocols such as NetFlow, sFlow, SPAN, RSPAN, CLI ...
