5G Network

§ Tremendous increase in No. of conneted Mobiles

slide-3
SLIDE 3

5G Network: 3 types of packet losses (1/2)

  • 1. Congestion losses:

slide-4
SLIDE 4
  • 2. Wireless losses
  • 3. Mobility losses

5G network: 3 types of packet losses (2/2)

§ Q: how to avoid impact of type 2,3 loss on congestion control mechanism? § TCP westwood: not consider mobility loss.

ICN opportunities

§ Connection-less transport model § We propose: ü WLDR (wireless loss detection and recovery) ü MLDR (mobility loss detection and recovery) § WLDR + MLDR -> address impact of loss

  • n congestion control

Outline

§ WLDR+ evaluation § MLDR+ evaluation § Combining WLDR+MLDR § conclusion

WLDR: related work

§ Transport layer solution: I-TCP: buffering at proxy high § Link-layer based solution: Snoop TCP: mac layer specific § Explicit notification solution: zigzag: effective for particular conditions

slide-8
SLIDE 8

WLDR: basic idea

§ Hop by hop mechanism § Loss detection: channel sequentiality § Loss notification: explicit notification § Loss recovery: retransmit by the sender

No per flow state Light weight No distinction of consumer/producer

slide-12
SLIDE 12

WLDR evaluation: 3 schemes compared

§1. detect and recover at consumer:

§2. explicit notification to consumer

retransmit

§ 3. WLDR

retransmit

WLDR: evaluation results

higher gain at big timer independent from timer

SLIDE 15

MLDR: basic idea

15

§ 2 cases: consumer or producer § consumer mobility loss: retransmit immediately after handover § probucer mobility loss:

  • n the fly rerouting

hoping one hop on the reverse path is updated

Conclusion

WLDR + MLDR: § Remove dependency from application timers § Flow completion time reduction § interest satification time reduction

Thank you!

Q: Wireless & mobility losss mistreated as congestion signal?

23

§Most TCP does not incorporate this problem well §Some does: TCP westwood, not consider mobility loss at all
