How to receive a million packets per second
Last week during a casual conversation I overheard a colleague saying: "The Linux network stack is slow! You can't expect it to do more than 50 thousand packets per second per core!" That got me thinking. While I agree that 50kpps per core is probably the limit for any practical application, what is the Linux networking stack capable of? Let's rephrase that to make it more fun: On Linux, how hard
Receive Side Scaling and Receive Packet Steering
Lets cover some basic terminologies before we dig into Receive Side Scaling and Receive Packet Steering. Network Interface Card: A network interface controller (NIC) (also known as a network interface card, network adapter) is an electronic device that connects a computer to a computer network/ Modern NIC usually comes up with speed of 1-10Gbps. #Find your NIC speed [root@machine1 ~]# ethtool eth0

PCとpktgenで行くショートパケットワイヤレートの旅
冒頭 「ねぇ、秒速1,488,095フレームなんだって」 「え、なに？」 「1Gbpsで最小フレームを送信可能なフレームレート。秒速1,488,095フレーム」 「ふーん・・・」 そりゃあ「ふーん・・・」ってなるな？ このフレームレートに到達しなければ1Gbpsを処理できているとは言えない。 従って、1Gbpsを処理できているか試験するために、汎用PCでこのフレームレートに到達する必要がある。 （1,000,000,000 bit = 125MB, 125MB/(60+4+12+8) = 1,488,095として計算） では本題に入ろう。 はじめに pktgenは、Linuxのカーネルに搭載されたトラフィックジェネレータ。 いつぞやからメインラインにカーネルモジュールとして同梱されるようになったので、恐らく2.6.26以降辺りから使えるのではないかと思う。 使い方 さしあたり、構成はループ
Queueing in the Linux Network Stack
[A slightly shorter and edited version of this article appeared in the July 2013 issue of Linux Journal. Thanks to Linux Journal’s great copyright policy I’m still allowed to post this on my site.

They allow for asynchronous modules to communicate, increase performance and have the side affec

10 Gbit Hardware Packet Filtering Using Commodity Network Adapters
10 Gbit Hardware Packet Filtering Using Commodity Network Adapters Prerequisites All the concepts and code described in this page requires modern networking hardware, an Intel 82599-based (e.g. Intel X520) or Silicom Director 10 Gbit NIC and a recent Linux kernel (>= 2.6.31). Developing efficient networking applications in Linux is not a straight forward task and requires a fair amount of understa
