OpenNOP – Open Network Optimization Platform – OpenNOP is an open source Linux based network accelerator. It's designed to optimise network traffic over point-to-point, partially-meshed and full-meshed IP networks. The goal of OpenNOP is to increase network performance over low speed network connections such as ISDN, DSL, DS1, frame-relay, VPN and other network circuits. To accomplish this we can use a variety of techniques such as compression, deduplication, caching and protocol spoofing. The objectives for OpenNOP are: Produce a low cost solution to increase network performance, improve the end user experience and deliver this in a easy to use appliance image. Provide a single solution for networks on terrestrial, cellular and satellite systems. Facilitate an open framework that can be extended by 3rd party modules to improve specific network traffic.
