Re: bandwith vs. caps
Great analogy. Networks are scarce in resources, but in peak usage utilization (bandwidth), not aggregate (consumption). By vendors offering different tiers, they actually exacerbate the situation (do I really need 35 Mb/sec) due to this burstiness.
However if they use QoS, they inherently need to do DPI to classify tiers so realtime doesnt get killed (say VOIP) versus BT which is a consumption factor. We dont want them throttling or looking at our stuff, so the network engineers need to figure out proper oversubscription ratios and link management, just like in any network design.
Consequently in datacenters, there are real resource constraints (QoS in storage/server is still infantile), so you are seeing VM's per se starting to get dials to control (QoS). Of course when you start doing that, you complicate the design because now you are making scarcity decisions in a point in time (QoS Policy) when peak demands may require adaptive bandwidth handling. Ouch. You can see how Rogers messes that up regularly. My inlaws cable experience (rogers no Bhell) is like 1979.
So I see innovative companies coming up that manage bandwidth at the app/stream (like Netflix) and over time there may be some conversation between the stream (application) and transit to "agree" on what is best effort.
In any case the announcement by Verizon that one can stream 20+ channels via IP through an xbox is good, because they would have a harder time justifying realtime IP and congestion, when in fact multicast streaming is going on. So maybe Fios gets a pass for now.
With docsis 3, these cablecos are up to snuff, so they are just maximizing profit, plain and simple. I took a look @ TWC Q3 numbers and it came out to approximately $20/month/user was going to stock repurchases and dividend payouts. Now if that isn't waste, I dont know what is. I also looked at TW (parent) and their quarterly boldly states that revenue and profits for media are through the roof, the highest ever. Hmmm, piracy killing them. I won't even talk about Comcast and their Universal/NBC profits, and they are crying poor me.
No corporate blame here, if people pay $200/month for triple play, then they are going to keep charging more. Enough said. If I were in their shoes, I would do the same. They could have better cu service tho, and that doessn't cost much. At the same time people snap up iphones and dole out term fees. The signal to corporations is, line up the shots and warm up the LearJet.
