[KP] example services

[Larry Peterson]

Just sending along pointers to two papers that seem relevant to the
knowledge plane. The first,

    Characteristics of Internet Background Radiation. R. Pang, V. 
Yegneswaran,
    P. Barford, V. Paxson, and L. Peterson.

    http://www.cs.princeton.edu/nsg/papers/telescope.pdf

describes our preliminary experience monitoring "background radiation" 
on
unused IP addresses. This is an example of a sensor that might plug into
the KP.

The second,

    PlanetSeer: Internet Path Failure Monitoring and Characterization in
    Wide-Area Services. M. Zhang, C. Zhang, V. Pai, L. Peterson, and R. 
Wang.

    http://www.cs.princeton.edu/nsg/papers/planetseer.pdf

describes how we have instrumented a wide-area service (a CDN that runs 
on 150
nodes and initiates lots of TCP traffic) to passively monitor TCP 
connections,
and engage a widely-distributed probing mechanism to diagnose suspected 
failures.
This is an example of a diagnostic tool, although it is "stand-alone", 
as opposed
to plugged into a general KP framework.

P.S. Both papers are conference submissions (and hence, 
submitted-at-11:59pm-rough),
but neither are encumbered by a double-blinded review process.
