Message-ID: <20020718220521.F46506-100000@crimea.dzhan.com> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I'm using FreeBSD 4.5 and have custom applications that send receive network packets over both tcp and udp sockets. For the sake of an example, assume that the udp traffic is always constant, but the tcp traffic density changes. During times of heavy tcp traffic density, will udp messages which have been sent to the out queue typically wait in the queue longer before being sent out? Does tcp traffic get some sort of priority? If so, is there a way I can de-prioritize tcp traffic and up the priority of the udp traffic to make certain all the queued udp messages get out as soon as possible...? sysctl variables? does it depend on the network card driver, or perhaps i'm imagining something that isn't there and the two traffic types are totally isolated! ;) Thanks! --Ben To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
