Graded Discussion:
Scenario:
“VidzAudios.com" is a large online streaming company operating in America, this company has implemented packet switching for media streaming, keeping in view the importance of packet buffers; packet switches with various sizes of packet buffers are already installed in company’s network. For Media streaming, network administrator has assured to use efficient queue management algorithms to schedule packets accurately in accurate queue according to its destination.
This company now wants to launch a new voice call service through packet switching, and developed a new network scheduler for this purpose, but this scheduler is causing bufferbloat because of which the network becomes practically unusable for voice calls”.
Requirements:
1. How packet buffers can be beneficial for “VidzAudios.com", give any two advantages.
2. What could be the possible reason of bufferbloat in above scenario?

I have no idea why you would bother to ask this question here, rather than of the bloat mailinglist maintained by bufferbloat.net, nor are you supplying enough context for the question. Voip service suffers terribly in the face of the common overbuffered devices and head end gear throughout the internet, without mitigating techniques on the routers such as fq_codel or an aqm like pie. An example of the problem a tcp upload or download can induce on cablemodems is over 250ms of induced delay on this test, which blows your voip call budget completely.
