WAN Acceleration Solutions and TCP/IP Layer 2 Technologies for Network Performance Optimization
Overview
This paper examines WAN acceleration solutions and their implementation at TCP/IP Layer 2, focusing on technologies such as data reduction, compression, caching, and bandwidth management. The paper argues that modifications to Layer 2 frame formats enable these techniques to improve network performance and provide LAN-like efficiency across wide area networks by addressing latency and bandwidth constraints.

WAN Acceleration solutions utilize numerous technologies. The solutions include data reduction, compression, caching, packet coalescing, service tagging quality, and bandwidth management. Copies are cached locally when transferring files from the head office through the WAN. Besides, the compression step minimizes the file size, which reduces the time taken in transferring files through WAN (Aaron, 2008). Data reduction explores the files cached locally and transmits the changed data bytes by using the references to alterations. TCP is more subtle to latency because of its forthcoming nature, which requires two-way conversation when transmitting small data chunks. Bandwidth management addresses over-subscribed WAN links, and packet coalescing helps in the consolidation of numerous packets into one packet.
Aaron (2008) explains that layer 2 is the lowest in the TCP/IP model. Layer 2 is mostly used to transfer information between neighboring network nodes in a broad network area. The WAN hastening solutions are applied through the changes in the layer 2 format in various ways. For instance, the data reduction accelerates data transfer through WAN. After detecting duplicate data, references are sent to the appliance, and the device is instructed to deliver data locally instead of sending information over WAN. As such, data reduction helps in providing performance similar to LAN across the WAN. Moreover, compression helps in reducing the bandwidth used data crossing the WAN. Besides, latency affects the performance of the application over the WAN. Latency limits throughput severely with TCP massive information transfers.
