load sharing
Load sharing is the process by which traffic is divided over links in a link group on a packet by packet basis.
load spreading
If there is more than one equal path to a destination, Nortel Multiservice Switch node’s will pick two of them. Load spreading is the process by which nodes divide traffic, on a VC basis, over the two link groups on those paths and the links in the link group. The algorithm used ensures (under normal conditions) that all the traffic for a given VC follows the same path and uses the same links along that path.
local access transport area (LATA)
Also referred to as a service area by some Bell Operating Companies (BOC), a LATA serves two basic purposes: to provide a method for delineating the area within which the BOCs may offer services and, to provide a basis for determining how the assets of the former Bell System were to be divided between the BOCs and AT&T at divestiture.
The United States has been divided into 200 LATAs by the AT&T Modified Final Judgment. Each BOC may service more than one LATA, but BOCs are generally constrained from providing long distance service between LATAs. Long distance service within a LATA is provided by the LEC. Service between LATAs is provided by an IEC.
local address resolver
A component of connection address resolution (CAR) that performs the resolution of a destination address at the local level.
local area network (LAN)
A network that connects microcomputers, workstations, printers, and other devices together, limited to local distances.
