The usage of "HA lifetime" (RFC3775-update)

[RYUJI WAKIKAWA-2]

Hi

In RFC3775, the HA can advertise the HA lifetime by
the Home Agent information option carried in RA.
However, this home agent lifetime is only available in this option.

When MR boots up from a foreign link, there are several ways to get HA  
address such as
DNS lookup, DHAAD (no HA lifetime field is defined in DHAAD message),  
etc.

How should MN manage these HAs in the home agent list?

When the HA lifetime is not available,
should MN set INFINITY value for the HA in the home agent list?

When MN obtains HA at the foreign link and then back to the home,
shall MN update the HA lifetime of that HA to the value specified in RA?

MN might lose the HA due to the HA lifetime expiration if it return  
home.
If it never returns home, MN can keep the HA address forever
This is not fair:-)

I need some clarification how we can use this HA lifetime.

regards,
ryuji

ACM MobiCom is the premier international conference dedicated to
addressing the challenges in the areas of mobile computing and
wireless and mobile networking.  It has served as an exciting
international forum since 1995, addressing networks, systems,
algorithms, and applications that support the symbiosis of mobile
computers and wireless networks. This year, we will continue
this tradition, but we especially encourage the submission of papers
in the experimental systems area.  This area has seen exciting
developments in recent years and explicit efforts will be taken to
represent it strongly at MobiCom this year.

Authors are invited to submit full papers, challenges papers, student
posters, and research demos and exhibits, presenting new research
related to the theory or practice of mobile computing and/or wireless
and mobile networking. All submissions must describe original research,
not published or currently under review for another conference or
journal. Areas of interest include, but are not limited to:

  * Operating system and middleware support for mobile computing and
    networking
  * Architectures, protocols, and algorithms to cope with mobility,
    limited bandwidth, limited power and/or intermittent connectivity
  * Fundamental understanding of mobile computing and wireless  
networking
  * Wireless and mobile techniques for delay tolerant, mobile ad hoc,
    and wireless sensor networks
  * Security, privacy, and trustworthiness of mobile and wireless  
systems
  * Wireless access technologies (e.g. mesh systems, PANs)
  * Integration and interworking of wired and wireless networks
  * Protocols exploiting novel technologies such as UWB, MIMO,
    directional antennas, and software radios
  * Techniques for dynamic spectrum use
  * Architectures, algorithms and protocols for cognitive wireless
    networks and their integration in the Internet

                         ACM MobiArch 2008
                   An ACM SIGCOMM 2008 Workshop
                 Seattle, WA, USA, August 22, 2008

               The 3rd ACM International Workshop on
           Mobility in the Evolving Internet Architecture

Recent developments in wireless access technologies and mobile devices
are beginning to make widespread user, terminal and network mobility a
reality in the commercial Internet. At the same time, the Internet
architecture struggles to incorporate the functionality that will  
sustain
this increasingly more mobile and more dynamic Internet use. Efficient
mobility management and mobility optimizations, locator-identifier
splits, multihoming, security and related network operation and
management functions are still in the early stages of development. It  
is,
however, already clear that supporting widespread mobility poses to
significantly impact the original end-to-end design of the Internet.

At the same time, critical momentum is building to significantly revise
or even replace the current Internet architecture. Several substantial
Future Internet initiatives have started in Europe, the US and Asia, and
the topic is also actively being discussed in the vendor and network
operator communities. These Future Internet efforts offer the exciting
opportunity to design radically different approaches to supporting host
and network mobility and multihoming, and may eventually lead to an
internetwork architecture with significantly more advanced mobility
features than those that the piecemeal extensions of the current  
Internet
protocols result in.

MobiArch'08 welcomes submissions from both researchers and practitioners
that explore recent advances in architectures, protocols and emerging
technologies to enable mobility and multihoming in the Internet, as well
as concepts and designs to support widespread mobility and multihoming  
in
future internetworks.  Early results, position papers, systems and
measurement papers are particularly welcome.

TOPICS
MobiArch'08 covers all aspects related to mobility in the current and
future Internet, including, but not limited to:

  * Architectures and protocols for mobility support at all layers
    of the Internet protocol stack, as well as cross-layer approaches
  * Novel concepts to support widespread mobility and multihoming
    in a Future Internet
  * Routing and addressing issues (including locator/identifier
    splits) and their impact on the Internet architecture
  * Multihoming, including flow distribution and load-sharing for
    wireless and mobility
  * Performance evaluation, experimentation and modeling of
    Internet mobility
  * Models for mobility patterns and their experimental validation
  * New wireless technologies and services and their impact on the
    Internet architecture
  * Location management, positioning and data management for
    wireless and mobility
  * Accounting, access control, security and privacy issues and
    their impact on the Internet architecture
  * Social, economic, scalability and deployment issues

SUBMISSION GUIDELINES
Submissions must be no longer than six pages, including all figures and
references, must be in PDF format, and must follow the ACM formatting
guidelines (http://www.acm.org/sigs/publications/proceedings-templates).
Submissions that do not adhere to these requirements will be rejected
without further review.
Peer review is single-blind; the authors names and affiliations are to  
be
included on the submission. Submissions cannot be previously published  
or
be under concurrent review elsewhere. The submission of position papers
is encouraged; please clearly identify position papers as such when
submitting.

[Hesham Soliman]

I think this is a valid point but I don't know if 3775 is the right  
place to address it. Since DHAAD is the only mechanism defined in 3775  
there is no issue. Other RFCs that define other mechanisms need to  
address the missing information.

[RYUJI WAKIKAWA-2]

Hi Hesham

I guess this HA lifetime (Home Agent Information Option) might be
originally introduced for the management of home agents operated on  
the same link.
Indeed, all the description for this option are for the Home Agent  
operation in RFC3775.

We should clearly state that this option is used only for HA and not  
for MN.
The usage of the home agent information option can be limited to the HA.
We just need to add 1-2 lines for the better clarification of this.

what do you think?

regards
ryuji

[Ben] Most likely, HAs on home link uses lifetime to compute preferences on
the avaliability of HAs, since 3775 states that HA will reply MN in the HA
list a number of prefered HAs.

[Ben] Why limit for HA usage? You pointed out in your previous mail that
since MR/MN does not know HA lifetime, is it not better to also inform MR/MN
of HA's lifetime in the HA list to advert those issues you raised up?

Benjamin Lim

[George Tsirtsis]

Guys,

I am not sure I follow you.

My understanding of the HA advertising a Lifetime on a link is that it
allows nodes on the link to (1) discover the HA address (2) cache the
HA address for as long as the lifetime indicates. This makes sense *on
link* since end nodes may discover the HA capability but they may also
have no use for it for a while (e.g., until a handoff to a foreign
link).

If  this explanation is correct, I would argue that when the HA is
discovered from a foreign link e.g., using DHAAD, DNS, DHCP etc, the
HA address must be used immediately and thus should NOT be cached. In
other words the MN should discover the HA address when it needs it and
then either engage with it or forget about it.

Does this make sense?

George
