i have a client that is looking to use DVB/IP to blast ip packets into various
geographic areas.
DVB/IP is basically piggy backing ip packets on Digital Video Broadcast
satelite signals, allowing the end-users to collect the packets with a
rather inexpensive receiving dish.
the end-user will need some normal method of sending their packets out,
typically via dial-up into a local ISP.
this is nothing new, direct PC/ hughes have been doing it for a while, although
i don't know if they are/were using DVB/IP, but a similar set up.
teleglobe markets a service where they will advertise some subnets on your
behalf, take the incoming packets and spew them into the areas you are looking
to go.
when investigating this, i initially thought it was great.
i started discussing issues i had, like how it would be a good idea to have the
ingress of the DVB/IP network-wise close to the client's internet egress.
this would reduce some of the problems of asymetric routing.
i also pointed out, that it would be a good idea to have some kinda system
in front of the DVB/IP so that you could do some level of firewalling against
DoS attacks and such.
i then found out that teleglobe makes no provision for the customer to
filter the packets before they hit the DVB/IP uplink.
the best they offered was to allow an out-of-band (ie. almost paperbound
procedure) configuration of an access list on their router.
are their any other DVB/IP providers who will allow my clients to install
a firewall/filter box in front of the DVB/IP uplink?
