------ 学习 ------ 顶， 还在学习计算机网络…… ------ 哈，我也是来学习的 ------ xuexi ------ NetLimiter is client-side traffic shaping and monitoring software for the Windows operating system.[1] Unlike most traffic-shaping utilities, which are based on centrally managed hardware, NetLimiter is a software-only solution. This has the advantage of being less expensive to deploy, but can result in being more difficult to manage its use across more than one computer.[citation needed] While it has a significant market among more technically-minded computer users, in medium-to-large networks it becomes difficult for administrators to maintain multiple copies of configuration files.[citation needed] It is, however, useful for simulating slow links between departments showing how the applications will work when deployed to slower sites.[citation needed] It is often lumped together with other free or shareware in articles[2] that present the reader with 'essential' applications and poweruser-type utilities.[3] ------
