Re: [Exede] Discussion: Current Status Wednesday January 23, 201

The Network Management Policy still activates on my spot beam sometimes during the day and evening indicating that congestion is still present. However, prime time slowdown is not present every day like it was for 2.5 years prior to Exede.

The Network Management Policy

Actions are based upon:

1. A beam's total bandwidth

2. Bandwidth bought from Tier One Provider

ISPs since early 90s and onward tended to hold off on buying bigger pipes until they perceived it was warranted. You may remember, there were 16 or 32 dial-in lines using a 56Kbps internet pipe. But, back then, NMP demons weren't around, so all users shared equally.

At Riverside Gateway for Anik-F2 users, its rather doubtful maximum bandwidth was bought for every beam when a NMP demon could equalize loading across all beams with a smaller pipe. WE are talking dollars/cents here, big dollars/cents that bean counters cherish, and who get bonuses for being a scrooge. Hence, NMP demon can reduce your total pipe size and server loading via prioritizing traffic; and of course, this reduces your total economic spending.

Hence, in some states, a beam's total bandwidth may never be utilized, and when you have a number of beams at a gateway, they can "share" total bandwidth bought with all users equally via NMP demon prioritizing traffic.

That said, ViaSat's CEO has stated he wants users to have good experiences...so some of the previous practices are being phased out whenever possible.
