In slow economic times, many businesses focus on increasing their profitability by improving the efficiency of their existing operations, increasing employee productivity, and lowering operating costs. Despite the latency and jitter inherent in shared networks, modern technology allows satisfactory transport of voice and video communications on these networks. The reason is that the links are shared, and packets must be entirely received at one switch before moving to the next. If the circuit carries computer data, the usage of this fixed capacity may not be efficient. This variation in usage between none and maximum is typical of computer network traffic. Dual-homed topologies are also more difficult to implement because they require additional, and more complex, configurations. The WAN Optimization industry study concludes with a list of leading companies/suppliers operating in this industry at different stages of the value chain. The switch determines the onward route by looking up the identifier in tables held in memory. Wireless Area Network. It defines how point-to-point links communicate when using optical fiber and SONET (Synchronous Optical Network) or SDH (Synchronous Digital Hierarchy) communication protocols. Layer 1 protocols describe how to provide electrical, mechanical, operational, and functional connections to the services of a communications service provider. Layer 2 protocols define how data is encapsulated for transmission toward a remote location and the mechanisms for transferring the resulting frames. WAN is the abbreviation of ….1.
