Message-ID: <20020514213034.A7529@atropos.snu.ac.kr> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.4i Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I've used dummynet bridge for bandwidth manangement in my company. Dummynet provides bandwidth management service by limiting specified traffic. Maybe limiting ability of dummynet is derived from its origin of network delay simulator. But I really want to use (or implement if I can) is bandwidth reservation. (I'm not sure it is appropriate term for that.) Assume that bandwidth is reserved for some traffic. If there is no traffic in specified traffic, then other kinds of traffic should be able to use the bandwidth. When the specified traffic occurs, reserved bandwidth should be guaranteed. In other words, bandwidth guarantee by reserving not by limiting. How should dummynet be modified to meet the need? If there is related works or papers, please let me know. -- Kyunghwan Kim redjade@atropos.snu.ac.kr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
