  1. Network (Internet) Neutrality CMPT 771 Qiang (Scott) Zhang

  2. Introduction • What is Network Neutrality? • Tim Wu in 2003 • A policy meant to limit a new kind of discrimination: Internet Discrimination • Filtering of data packets

  3. The Debates • Technological detail • Quality of service • Economic analysis • Differential pricing can increase the economic warfare • Incentive to invest in new technologies • Regulatory perspective • Internet freedom • ISPs’ discrimination

  4. Intermediate Approach – x model • Dividing the capacity of each ISP into two parts • A fraction 1-x of an ISP’s capacity every T seconds to operate as current • A fraction x every T seconds is granted ownership rights • For example, T = 10ms, x = 0.1 • Delay for no-premium user is 1 ms per router

  5. Math Equations • Is the ISP profit • U is user surplus • S is social surplus

  6. Graph

  7. Appling x Rule to All Links

  8. Worse scenario

  9. Enforcement of x-rule • Hardware-restrained enforcement • Switch manufactures are responsible for ensuring that the mandated fraction is maintained. • Operational enforcement • Each switch is mandated to record the capacity usage by premium traffic

  10. Technical Issues 1 • Traffic differentiation • Switch must posses the ability to distinguish between basic and premium traffic • Type of service filed in IPv4 • Optional field • Tamper-proof counters • Traffic statistics • Network management services -- SNMP

  11. Technical Issue 2 • Switch accessibility • Mapping between IP addresses and switches and release such information to inspecting authority • Authentication and data encryption • Preventing unauthorized access • Prevent data intercept and manipulation on the path
