The journey of a packet through the linux 2.4 network stack Harald Welte laforge@gnumonks.org 1.4, 2000/10/14 20:27:43 This document describes the journey of a network packet inside the linux kernel 2.4.x. This has changed drastically since 2.2 because the globally serialized bottom half was abandoned in favor of the new softirq system. 1. Preface

The o w of the packet through the linux network stack is quite intriguing and has been a topic for research, with an eye for performance enhancement in end systems. This document is based on the TCP/IP protocol suite in the linux kernel version 2.6.11 - the kernel core prevalent at the time of writing this document.

Jul 07, 2016 · For the general user the Linux network stack is the right choice. Although it's less exciting than rewriting TCP stacks, we should focus on understanding the Linux stack performance and fixing its problems. There are some serious initiatives underway to improve the performance of the good old Linux TCP stack. Those were a few handy commands to quickly check the network bandwidth on your linux server. However these need the user to login to the remote server over ssh. Alternatively web based monitoring tools can also be used for the same task. Ntop and Darkstat are some of the basic web based network monitoring tools available for Linux. Jan 30, 2016 · netif_receive_skb will either continue sending network data up the networking stack, or hand it over to RPS for processing on a different CPU. configure RPS For RPS to work, it must be enabled in the kernel configuration (it is on Ubuntu for Linux kernel 3.13.0), and a bit mask describing which CPUs should process packets for a given interface Linux Networking and Android. Linux is used extensively as the base for Android phones. The Linux networking stack has different needs for mobile devices than to data centre devices. Phone moves all the time, connects to different networks with varying quality. Phones are connected to multiple networking nearly all the time. Nov 19, 2018 · Get to know networking basics with this tutorial from our archives. Linux grew up with a networking stack as part of its core, and networking is one of its strongest features. Let’s take a practical look at some of the TCP/IP fundamentals we use every day. It’s IP Address I have a peeve. OK, more than one. But … Recently, one of my work is to write network stacks using C++ in an OS developed by my team which is totally different from linux. However, I think how a deep understanding of linux network stacks may be helpful to design and implementation a well one. Mar 15, 2015 · If the received frame is of type data, it is translated into 802.3 frame (by __ieee80211_data_to8023) and is delivered to the networking stack via netif_receive_skb. From then on, the network protocol block will parse and decode the protocol header. If the received frame is of type management, it is processed in ieee80211_sta_rx_queued_mgmt.
