TIPC


Introduction

TIPC is a LAN protocol, originally designed by Jon Maloy at Ericsson. Its purpose is to provide an efficient, transparent, and scalable communication mechanism for a wide range of possible cluster configurations. It has been in the linux kernel since 2.6.16.
http://tipc.sf.net is the main TIPC site.

networkmanager

NetworkManager is designed to be fully automatic and "Just Work" without intervention, but friendly desktop applications allow users to control the state of the network if they desire. NetworkManager keeps a list of all available network devices, and updates that list when you insert or remove new network cards, dock your laptop, etc. Using this list, NetworkManager determines the best device to use for the computer's network connection.

bonding

The Linux bonding driver provides a method for aggregating
multiple network interfaces into a single logical
bonded interface.
The behavior of the bonded interfaces depends upon the mode; generally
speaking, modes provide either hot standby or load balancing services.
Additionally, link integrity monitoring may be performed.

sk_buff

All network-related queues and buffers in the kernel use a common data structure, struct sk_buff. This is a large struct containing all the control information required for the packet (datagram, cell, whatever). The sk_buff elements are organized as a doubly linked list, in such a way that it is very efficient to move an sk_buff element from the beginning/end of a list to the beginning/end of another list.

ifb

The Intermediate Functional Block device is the successor to the IMQ iptables module that was never integrated.
Advantage over current IMQ; cleaner in particular in SMP;
with a _lot_ less code. Old Dummy device functionality is preserved while new one only
kicks in if you use actions.

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.

wireless:txformat

This page describes the transmit frames that various hardware needs to get a frame on the air. It should allow us to get an overview what formats the stack needs to support and to help on the decision whether we will use 802.11 frames or 802.3 emulation when communicating to upper layers.

  • Date: Monday, 3 December 2007

netconf

Netconf is a yearly, by-invitation-only, Linux community conference running for the third year. The agenda has a clear focus on kernel level networking. Attendees are the main maintainers and developers of the Linux networking subsystem. Invitation is issued only 10-15 people who have provided significant contributions.

For more information see the conference sites:
