Title : Ivip Mapping Database Fast Push
Author(s) : R. Whittle
Filename : draft-whittle-ivip-db-fast-push-02.txt
Pages : 42

>From the base of draft-whittle-ivip-arch-03 and later, this ID
describes in greater detail Ivip's fast-push mapping distribution
system. This accepts mapping changes from end-user networks or
organizations they authorise to make these changes. The mapping
changes are handled by RUAS (Root Update Authorization Server)
companies who collectively run a small set of Launch servers and a
global network of Replicator servers. Each second, the Launch
servers send sets of packets with mapping updates to a larger number
of level 0 Replicators, each of which gets at least two feeds of
these mapping updates from different Launch servers. Each Level 1
Replicator fans out the mapping changes to multiple Level 2
Replicators, which also receive at least two feeds from upstream
Level 1 Replicators. In this way, within a fraction of a second, the
mapping changes are fanned out securely and reliably to full database
query servers (QSDs) in ISPs and some end-user networks all over the
Net. Additionally, QSDs can download missing packets and snapshots of
segments of the mapping database. A WAG of 4 billion mapping changes
a year gives a raw data rate for IPv6 mapping changes of only 32kbps.
TTR mobility only involves mapping changes if the MN moves a large
distance, such as 1000km. Multihoming service restoration updates
would be infrequent. Mapping changes for TE could be numerous
depending on cost. It is hard to imagine a scenario where mapping
changes would present significant difficulties in terms of bandwidth
or in terms of the capacity of QSDs to handle them.
