Hi all,
We have submitted a new draft describing the protocol which can be used
by the ALTO servers to exchange the information on topology.
The main motivation for developing the protocol is that routing paths
and policies in the Internet aren't symmetric and therefore a local ALTO
server can't guide local peers optimally. An ALTO server may use the
information obtained from other servers for better optimization of peer
rating algorithm. Several motivations for the proposal of the
Inter-ALTO communications protocol are described in more detail in
Section 2 of the draft.
The protocol described in the document has been already implemented and
is being tested now. The impact of the introduction of the Inter-ALTO
protocol on the BT traffic has been presented in: Z. Dulinski, M.
Kantor, W. Krzysztofek, R. Stankiewicz, and P. Cholda, ``Optimal Choice
of Peers based on BGP Information,'' Proceedings of 2010 IEEE
International Conference on Communications (ICC), May 2010, (available
from IEEE Xplore and from the authors upon request). Additionally, we
have done simulations using the scrap of the real Internet topology.
Peer rating algorithm was optimized with respect to reduction of ISPs
costs related to the inter-domain traffic. The information from remote
ALTO servers enables reduction of traffic on expensive links by
promoting remote peers that exchange traffic over cheaper links. The
results are promising (however they haven't been published anywhere yet).
We invite you for a discussion about the draft.
Best regards,
Piotr Wydrych and Rafal Stankiewicz, on behalf of all authors

The ALTO service provides the information, which can make
communication between applications more efficient, especially in case
of overlay applications. Such applications can use the information
to perform better-than-random peer selection. The ALTO protocol
conveys network information to applications. The protocol definition
of this document extends the functionality of this ALTO service by
introducing a standardized manner of communications between ALTO
servers. A new inter-ALTO protocol is proposed, which enables the
exchange of information between ALTO servers. The servers can
coordinate actions and can introduce policies, which provide
communication between applications localized in cooperating
Autonomous Systems with a higher performance and a better cost
efficiency.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
