Five Challenges

Known solutions to high BW "problems"

Increase the clock rate

• Increases BW, but makes BW-delay product (BDP) worse

Multiplex

• Removes the goal of "BDP to the user"

Use large payloads

• Equivalent to turning off the protocol

Increase the window size

• Works only if there exists data to send (helps, but not for WAN Gb BDP)

Relocate everything

• Removes the goal
