traceroute

overview

Traceroute is a system administrators utility to trace the route IP packets take from a source system to some destination system.

There are several implementations of this tool. Most distributions include the Lawrence Berkeley National Laboratory Network Research Group version. There is two implementations written especially for LiNUX, one by Olaf Kirch and other one by Dmitry Butskoy.

toe

TCP Offload Engine (TOE) is the name for allowing the network driver to do part or all of the TCP/IP protocol processing. Vendors have made modifications to Linux to support TOE, and these changes have been submitted changes for kernel inclusion but were rejected.

Introduction

iperf

iperf is a network performance testing tool hosted here

napi

NAPI ("New API") is an extension to the device driver packet processing framework, which is designed to improve the performance of high-speed networking. NAPI works through:

tcp_testing

TCP testing in Linux is an continuous process. These tests are concerned with the behavior and correctness of the TCP protocol in the Linux kernel.

More will be added to this page soon.

tcp

Linux has the most RFC compliant TCP implementation. Over time this page will have more details on it's implementation and areas such as congestion control.

"Based on all the measurements I’m aware of, Linux has the fastest & most complete stack of any OS.."

pktgen

Linux packet generator is a tool to generate packets at very high speed
in the kernel.

generic_netlink_howto

This document gives a brief introduction to Generic Netlink, some simple
examples on how to use it and some recommendations on how to make the most of
the Generic Netlink communications interface. While this document does not
require that the reader has a detailed understanding of what Netlink is
and how it works, some basic Netlink knowledge is assumed. As usual, the
kernel source code is your best friend here.

tso

TCP Segmentation Offload is supported in Linux by the network device layer. A driver that wants to offer TSO needs to set the NETIF_F_TSO bit in the network device structure.

What was the purpose of this last edit, 00:18, 18 April 2007 by JyqXan, it seems to remove large chunks of the text for no apparent reason? Unless JyqXan has an explanation I propose we revert the latest change.

There are a few of these random mutilations going on by randomly named users. No idea why! I think I might have accidentaly marked this as patrolled but don't know how to reverse. User:Imcdnzl

Okay, thanks both for the explanation and the fix.

talk:ifb

I do not have ifb installed on my kernel and i do not know how to install. There is no web where i can find information. Can anybody help me?

Answer: It is part of the standard kernel starting with 2.6.12.
To enable it you need to enable:

netlink

Netlink is a flexible, robust, wire-format communications channel typically used for kernel to user communication although it can also be used for user to user and kernel to kernel communications.
