Highspeed switch that forwards packets between datalink segments. Most LAN switches forward traffic based on MAC addresses. This variety of LAN switch is sometimes called a frame switch. LAN switches are often categorized according to the method they use to forward traffic: cutthrough packet switching or storeandforward packet switching. Multilayer switches are an intelligent subset of LAN switches. Compare with multilayer switch. See also cutthrough packet switching, storeandforward packet switching.

A channel that conveys information by writing data to a common storage area where another process can read it. A covert channel that involves the direct or indirect writing of a storage location by one process and the direct or indirect reading of the storage location by another process. Covert storage channels typically involve a finite resource that is shared by two subjects at different security levels. Covert channel involving the direct or indirect writing to a storage location by one process and the direct or indirect reading of the storage location by another process. Covert storage channels typically involve a finite resource (e. g. , sectors on a disk) that is shared by two subjects at different security levels.
