caboom: Ima slicnosti sa rr ali ovde ti kontrolises tacno koja konekcija ce da se koristi, dakle imas totalnu kontrolu. Program je veoma jednostavan, ima sve sto je potrebno a nije toliko poor posto parametri mogu da se menjaju u toku rada programa (covek moze da ih menja, svaka thread-konekcija ih po nastanku cita) a sa nekim dodatnim programom (inteligentnijim) mozes da uzimas u obzir jacinu linka, jacinu racunara, load average i ostale parametre da bi odredio kome ide sledeca konekcija i modifikujes config file.
bojan: load balancer npr. sedi na portu 80 na www.elitesecurity.org
i prerasporedjuje zahteve na es1.elitesecurity.org, es2.elitesecurity.org transparentno da ti nemas pojma sta se iza nalazi,imas utisak da koristis samo glavni server. Na isti nacin moze da se balance-uje smtp, pop, ftp i skoro svi ostali tcp protokoli. Umesto posebnih masina (es1) mogu cak i da se koriste odvojeni portovi na istoj masini.

2. You may modify your copy or copies of the Program or any portion of it,
thus forming a work based on the Program, and copy and distribute such
modifications or work under the terms of Section 1 above, provided that
you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any part
thereof, to be licensed as a whole at no charge to all third parties
under the terms of this License.
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the most ordinary way, to print or display an announcement
including an appropriate copyright notice and a notice that there is
no warranty (or else, saying that you provide a warranty) and that
users may redistribute the program under these conditions, and telling
the user how to view a copy of this License. (Exception: if the
Program itself is interactive but does not normally print such an
announcement, your work based on the Program is not required to print
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
