From: sjorha@attbi.com Date: Tue, 22 Oct 2002 18:05:03 +0000 How does the NIC perform the segmentation? Does the NIC perform flow control by monitoring the ACKs received or does the 64k segment get segmented and sent without regard for flow control or is some other flow control algorithm used? No, it gets a template tcp/ip header + (64K - header_size) of data. Then the NIC generates MTU sized packets, generating fresh TCP/IP headers based upon the given template. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
