[Tech] Come suddivisione il traffico Internet tra piùproviders?

[Alessandro Zarrilli]

Ho appena trovato qualcosa di interessante che forse fa al caso mio. Esiste
qualcosa di simile e di migliore?



DESCRIPTION
       Balance is a simple, generic "userland" TCP  proxy,  which
       allows  simple  round  robin  load  balancing and failover
       between serveral destinations.

       Balance accepts connections on the given port and forwards
       them  to the supplied destinations.  At least one destina­
       tion must be specified.  If there are two or more destina­
       tions specified balance performs a simple round robin load
       balancing between these destinations.

       Hosts may be specified either by its name  or  by  its  ip
       address.  Ports  may  be specified either alphanumerically
       (as in /etc/services) or numerically.  If there's no  port
       specified  in  a destination the destination port defaults
       to the source port that balance controls.

       Failover to another destination (a  "channel")  occurs  if
       the connection is refused on the current channel or if the
       connect timeout is reached trying to establish  a  connec­
       tion.  If  all  possible destinations (channels) currently
       fail, the initial connection to balance itself  is  closed
       immediately.

EXAMPLES
       $ balance smtp host1.test.net host2.test.net
              Connection to the local SMTP port will be forwarded
              alterating to the SMTP port  on  host1  and  host2.
              Balance runs automatically in background.


       $ balance -fp imap mailserver
              Connections  to  the local IMAP port will always be
              forwarded to the host "mailserver".  Balance  stays
              in  foreground  and all data is printed in readable
              format on stdout.


       $ balance -f 8888 host1 10.1.1.1:8000
              Connections to the local port  8888  are  forwarded
              alternating  to  host1,  port  8888  and  the  host
              10.1.1.1, port 8000.  Balance stays  in  foreground
              connected to the "controlling tty".
