Day 18

Network neutrality is a principle that believes that all internet traffic should be treated equally.
Absolute non-discrimination, limited discrimination without QoS tiering, and limited discrimination and tiering. This principle will allow networks to carry info and support all applications. The internet is working to be neutral state. It is striving to make a law. If this law is passed it will make everything a little slower and maybe more expensive.

(From Wiki)
"Absolute non-discrimination:
Tim Wu: "Network neutrality is best defined as a network design principle. The idea is that a maximally useful public information network aspires to treat all content, sites, and platforms equally."[2] Susan P. Crawford "believes that a neutral Internet must forward packets on a first-come, first served basis, without regard for quality-of-service (QoS) considerations."[11]

Limited discrimination without QoS tiering:
United States lawmakers have introduced bills that would allow quality of service discrimination as long as no special fee is charged for higher-quality service.

Limited discrimination and tiering:
This approach allows higher fees for QoS as long as there is no exclusivity in service contracts. According to Tim Berners-Lee: "If I pay to connect to the Net with a given quality of service, and you pay to connect to the net with the same or higher quality of service, then you and I can communicate across the net, with that quality of service." "[We] each pay to connect to the Net, but no one can pay for exclusive access to me."

Probems with QoS:
dropped packets, delays, error, jitter, out-of order delivery.

Tiered Internet:
Allows telecommunication providers to divide up there traffic onto more than one tiers.

Verizon is against network neutrality. They are arguing that we should be able to prioritze based on importance. Traffic is based on what type of packet you are sending. Ex: Spam would be the last to go when sending a message because it is the least important to Verizon.
