In computer networking, a media access control attack or MAC flooding is a technique employed to compromise the security of network switches.The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where it is not normally intended to go.
RFC 791 describes the procedure for IP fragmentation, and transmission and reassembly of IP packets. [1] RFC 815 describes a simplified reassembly algorithm. [2] The Identification field along with the foreign and local internet address and the protocol ID, and Fragment offset field along with Don't Fragment and More Fragments flags in the IP header are used for fragmentation and reassembly of ...
A hub is a component of a network with a high-degree node. Hubs have a significantly larger number of links in comparison with other nodes in the network. The number of links for a hub in a scale-free network is much higher than for the biggest node in a random network, keeping the size N of the network and average degree <k> constant. The ...
In practice, this means that video over IP will not work on overloaded networks. Since IP does not of itself offer any traffic guarantees, this must be applied at the network engineering level. One approach to this is the "quality of service" approach which simply allocates sufficient bandwidth to video-carrying traffic that it will not congest ...
4-port 10BASE-T Ethernet hub with selectable MDI-X/MDI port 8-port Ethernet hub with one 10BASE2 connector and eight 10BASE-T ports. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub [a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.
A common scenario in the early years of computing was an overload condition known as thrashing where the aggregate server performance becomes severely degraded, such as when two departments of a large company attempt to run a heavy report concurrently on the same mainframe. In such a situation, the designation of the server hog becomes a ...
Ethernet over USB is the use of a USB link as a part of an Ethernet network, resulting in an Ethernet connection over USB (instead of e.g. PCI or PCIe).. USB over Ethernet (also called USB over Network or USB over IP) is a system to share USB-based devices over Ethernet, Wi-Fi, or the Internet, allowing access to devices over a network.
The TURN server receives the peer UDP datagram, checks the permissions and if they are valid, forwards it to the client. This process gets around even symmetric NATs because both the client and peer can at least talk to the TURN server, which has allocated a relay IP address for communication.
