three new netmap tools: pcap player, link emulator, load distributor

[Luigi Rizzo]

Hi,
I have put some new tools on the github's netmap page
https://github.com/luigirizzo/netmap in the apps/ directory

All are under a BSD license.

nmreplay
  a fast pcap replay tool (a-la tcpreplay) with programmable rate.
  Joint work with a few of my students in Pisa.

​tlem
  a link emulator, dummynet style (but without the packet filter),
  sustaining 20Mpps/ 40Gbit. TLEM will be presented at asiabsdcon
  and a paper is at http://info.iet.unipi.it/~luigi/research.html

lb
  a packet distributor that reads from a netmap port and distributes
  traffic to multiple netmap ports, using ze​ro copy and a user-defined
  hash function. This will be useful e.g. for people running multiple
  instances of traffic monitors such as bro, suricata and the like.
  It is not by chance that LB was originally developed by Seth Hall
  at Broala, who kindly made it available, and Giuseppe Lettieri who
  added a few features.

Feedback welcome

cheers
luigi
