Alternate Approach

• Routers enforce protection and fair allocations

  • Flow Random Early Drop (FRED), Fair Queueing (FQ)

• Advantage:

  • protection against misbehaving flows
  • co-existence of heterogeneous end-to-end
  • algorithms

• Disadvantage: complex

  • packet classification
  • per flow buffer
  • management
  • per flow scheduling
  • (FQ)
