Is there a way so that I can selectively limit bandwidth of a running process?

There is a whole list of applications here that can do this: alternativeto.net/software/netbalancer –  BGM Jul 29 at 15:17

I use NetBalancer. While its a paid software, a free version exists, but can restrict traffic on upto 3 processes at a time.

Net Balancer Free

By default it doesn't monitor internal LAN transfers and it doesn't balance until 80% of the bandwidth is used. You can configure it though. –  Jader Dias Jul 12 '11 at 20:16
This appears to work terribly bad on Windows XP. Instead of transparently narrowing the bandwidth, it appears to drop down packets/requests, half of times web pages won't open at all, displaying the default DNS search results instead, programs would go awry etc. –  GSerg Apr 9 '13 at 15:07
@GSerg dropping packets is just about the only way to "transparently narrow the bandwidth". (not that this helps fix any issues you're having on XP, of course...) –  romkyns Jun 19 '14 at 23:05

I use Net Limiter, which has a free version, but unfortunately you'll need to pay for the limitation feature.

NetLimiter is an ultimate internet traffic control and monitoring tool designed for Windows. You can use NetLimiter to set download/upload transfer rate limits for applications or even single connection and monitor their internet traffic.

Along with this unique feature, Netlimiter offers comprehensive set of internet statistical tools. It includes real-time traffic measurement and long-term per-application internet traffic statistics

No, the lite/pro versions, which allow traffic limiting, aren't free. –  demonkoryu Mar 28 '13 at 10:34
This one, on contrary, works quite good on Windows XP. –  GSerg Apr 9 '13 at 15:29

Internet facing router is a better place for traffic shapers, just like every entrance to VPN. PS i used to use netlimiter before installing alternate firmware on home gateway.

What alternative firewall? how did you do this? your answer is very vague –  Simon Sheehan Feb 25 '12 at 23:16
No traffic shaper supports IPv6 yet. –  Ian Boyd Jun 20 '12 at 16:44
And how exactly is a router supposed to know which process originates the traffic? –  romkyns Jun 19 '14 at 23:06
