Is there any way to limit udp traffic?

Hello all !

There are around 30 PCs in the office connected by wired network, plus
untold number of notebooks or other portable devices connected via
WIFI.

The PCs are running XP and Win7.

The number 1 problem that I am facing is the udp traffics. They are
taking a big chunk out of the available bandwidth.

Can anyone tell me is there a way to limit the udp traffic?

Thank you !

You don't have access to Google?

It said it's the "United Democratic Party" (The Gambia), a political
party in The Gambia.

Somehow I dont think that applies !!!!!

Then it said it's the "Usenet Death Penalty", a final penalty against
Usenet users or Internet service providers. Now that could apply on
this newsgroup, for people who dont use google. <lol>.

It's also "User Data Preservation", a feature of mobile phones that
retains user data after a firmware.

And it's also the "User Datagram Protocol" (UDP) is one of the core
members of the Internet Protocol Suite, the set of network protocols
used for the Internet. With UDP, computer applications can send
messages, in this case referred to as datagrams, to other hosts on an
Internet Protocol (IP) network without requiring prior communications
to set up special transmission channels or data paths. The protocol
was designed by David P. Reed in 1980 and formally defined in RFC 768.

UDP uses a simple transmission model without implicit handshaking
dialogues for providing reliability, ordering, or data integrity.
Thus, UDP provides an unreliable service and datagrams may arrive out
of order, appear duplicated, or go missing without notice. UDP assumes
that error checking and correction is either not necessary or
performed in the application, avoiding the overhead of such processing
at the network interface level. Time-sensitive applications often use
UDP because dropping packets is preferable to waiting for delayed
packets, which may not be an option in a real-time system.[1] If error
correction facilities are needed at the network interface level, an
application may use the Transmission Control Protocol (TCP) or Stream
Control Transmission Protocol (SCTP) which are designed for this
purpose.


I guess this last one must be the one that applies...

What UDP traffic in particular ?

What bandwidth...
Intranet ?
Internet ?



The UDP traffics are eating up a big chunk of the incoming Internet
bandwidth.

I am from a 3rd world country where Net feed is very expensive, and
very limited. Our company subscribes to 2 net feeds, both 4Mbps.

The UDP are cutting the 8Mbps (2 X 4Mbps) net feed to less than 1Mbps.

As for what UDP traffic? I can only guess because I do not know how to
trace the UDP traffics:

There are workers who frequent Youtube

And then there are who downloading / streaming movies from places like
PPStream.

I have tried blocking the PPStream IP but they are by-passing the
block by using VPN.

As for firewall, it's on the PCs. We do not have a central firewall.

Fire them.

This is not a technical issue.
