On Linux, network block device (NBD) is a network protocol that can be used to forward a block device (typically a hard disk or partition) from one machine to a second machine. As an example, a local machine can access a hard disk drive that is attached to another computer. The protocol was originally developed for Linux 2.1.55 and released in ...
Open source: Free: Linux distribution running from a RAM drive. Its original target was small appliances like routers, VPN gateways, or embedded x86 devices. However, it supports hosting other Linux guest OSes under LXC control, making it an attractive hosting solution as well. Uses Busybox and musl. ClearOS: Active: Red Hat Enterprise Linux ...
TAP, namely network TAP, simulates a link layer device and operates in layer 2 carrying Ethernet frames. TUN is used with routing. TAP can be used to create a user space network bridge. [2] Packets sent by an operating system via a TUN/TAP device are delivered to a user space program which attaches itself to the device. A user space program may ...
In case of failure, the network works in the Ring-Open status (Figure 2). For instance, in case of failure of a link connecting two MRCs, the MRM sets both of its ring ports to the forwarding state; the MRCs adjacent to the failure each have a disabled port (because of the link loss) and a forwarding ring port; the other MRCs have both ring ...
High-availability Seamless Redundancy (HSR) is a network protocol for Ethernet that provides seamless failover against failure of any single network component. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite. HSR does not cover the failure of end nodes, but ...
The Software for Open Networking in the Cloud or alternatively abbreviated and stylized as SONiC, is a free and open source network operating system based on Linux. It was originally developed by Microsoft and the Open Compute Project .
For most file systems, a program terminates access to a file in a filesystem using the close system call. This flushes file buffers, updates file metadata , which may include and end-of-file indicator in the data; de-allocates resources associated with the file (including the file descriptor ) and updates the system wide table of files in use.
Red Hat initiated the NetworkManager project in 2004 with the goal of enabling Linux users to deal more easily with modern networking needs, particularly wireless networking. NetworkManager takes an opportunistic approach to network selection, attempting to use the best available connection as outages occur, or as the user roams between ...
