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.

<br>
<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.

<br>> Yes , you are right, Provider
never can give us this stats. thats why maximum time get voice break

<br>> Dear Team Member,
<br>>
Thanks For your Suggestion. I know voice quality can not improve using any
firewall. firewall and voice quality is both are different. i saw if
network any firewall have which is create problem for voice termination.
but firewall is important to secure the network. i want to know any device
which can support voice termination.
<br>> and for voice quality issue i am not interest to get IPLC,
without IPLC how i can get good voice quality from public internet in
Bangladesh. any one have any Band width which can defer voice traffic and
data traffic when it is going through any pipe link. coz voice traffic
will be priority in public internet, how i can do this, or who can give
this type of service.,
<br>>
<br>>
<br>> and thanks
to roman bhai, that for voice termination workshop agenda,. It is very
important for Bangladesh.
<br>>
<br>> FOr routing we are
using Tier 1 provider. for compression we are using 20 ms payload size for
g729 call.

are lots of other factor like BW, Compression mechanism, routing mechanism etc.
