<div dir="ltr"><div><div><div>Dear Anirudda Da,<br><br></div>Thanks for your mail. If I'm wrong I think you are asking how bandwidth can be controlled in large level.<br><br></div>I have a very small experience in IIG. We do the bandwidth shaping in physical level as port basis. We don't do anything on Packet level as like Roman Vai said. But, all our cards are QUE cards. These QUE cards are very expensive, but it will give you a very good result on shaping bandwidth at the port. If you have more than 1gbps of Bandwidth to serve, I think you can use Aggregated Ethernet (AE). Better to use 80% efficiency for each port.<br>
<br>For Packet Shaping, I have a very worst experience on JUNIPER IDP 8200, which is a 10GE transparent DPI. It should give us so many options to control the packets, like blocking, passing etc. But, truly speaking your browsing experience will be too much worst and when we crossed 1 gbps of bandwidth it crashed and JUNIPER send a new one.<br>

<div>Transit operators normally do not shape traffic (bandwidth control) at packet level. Except some rate limiting for ICMP etc etc destine to their origin IP only. They normally control data rate at the signal level I.e. DSL, Ethernet, STM etc. So at the
packet level there is no issue as long as their interface queue (depend on hardware capacity) can handle those.�</div>

<div>Transit path main goal is clear IP packet, no shaping, their routers don't even check what QoS tag each packet is carrying. If you need any exception it need to be done case by case with your transit operator/s. � �</div>

<div>Dear Simon bhai,</div>
<div><br>
</div>
<div>I am not asking for our network. I am asking from learning point of view. ISPs like us use Allot, Packeteer, ET, MikroTik etc. I was wondering what the carriers/transit providers might use to shape up QoS for IP traffic (VoIP, IP Telephony, Video etc.).
International calls pass through one or more of these transit networks. If end to end QoS has to be ensured along the path, transit providers will have to use such an equipment at IP level. I feel, at Gigabit speeds, shaping up traffic without compromising
performance should be extremely difficult. I think,�<span>from transit
providers' point of view,�</span>IPLC is the best option for best QoS but I might be wrong. Inputs from the experts in this list are welcome.</div>
<div><br>

Relating to this thread, I'd like to know if there is any equipment that can shape up QoS traffic without affecting Non-QoS traffic at carrier networks where bandwidth is in hundreds of Mbps to tens of Gbps.
