Project to write a PILC BCP RFC: TCP Over Wireless

Project to write a PILC BCP RFC TCP Over
Wireless

• December 2000
• Hiroshi Inamura, Max Hata
• NTT DoCoMo
• Gabriel Montenegro
• Sun Microsystems

Why a TCP over wireless document?

• Aid uniformity in installed base of TCP
  implementations in handsets.
• ex. 15 million in Japan for current i-mode
• There is little information source where WAP will
  be going
• Internet convergence in WAP2.0
• The BCP already overdue for one year
• Initial set of volunteers from WAP-NG

Background

• WAP forum WPG-NG is completing drafting TCP
  specification for handsets, based on optimization
  techniques from IETF/PILC.
• Efforts have been made to find an optimal set of
  techniques for a wide range of wireless networks,
  ranging from slow networks to high speed networks
  like 2.5G/3G.
• During the process, a number of valuable vision,
  ideas and data have been accumulated in order to
  apply the optimization techniques to wireless
  networks.
• Now, time to put them into a BCP, entitled TCP
  Over Wireless to be shared by wider wireless and
  networking community.

Objective of the BCP TCP Over Wireless

• Provide an overview document with relevant
  pointers to other relevant PILC work.
• Ensure the goal of WAP-NG
• Internet Convergence
• Provide recommendations for wireless networking
  community

5
Scope

• More general perspective than TCP specification
  in WAP
• Provide overview, define domain and requirements
  and present a solution
• A short and succinct document with references to
  the other PILC documents
• Identify which of the considerations remain
  research topics.
• Research topics will be explicitly flagged as not
  part of any recommendations.

Task team members

• Support from within the WPG-NG/WAP working group
  results in this informal activity
• Volunteers from the working group
• Chief Editor Hiroshi Inamura - DoCoMo
• Gabriel Montenegro - Sun
• Joby James - Motorola
• Masahiro Hara - Fujitsu
• William Gilliam - HP
• and others

Schedule

• Kick off and go-ahead from PILC
• IETF Meeting, San Diego Dec. 15, 2001
• Develop outline of the Doc
• Mid Jan, 2001
• Proceed drafting
• WAP London, Feb.5-9, 2001
• Publish ID 1
• Mid Feb, 2001
