Description Usage Objects Variables References
Data from the 12 node CMU network used in Blocker & Airoldi (2011). The OD flows are actual, observed traffic from a CMU network. The topology does not, however, correspond to the original network due to security considerations.

The list cmu, which contains several objects:
A
, the routing matrix for this network
(truncated for full row rank)
X
, a matrix of
origin-destination flows formatted for analysis
Y
, a matrix of link loads formatted for analysis
A.full
, the routing matrix for this network
without truncatation for full row rank)
Y.full
, a matrix of link loads corresponding to
codeA.full
In this data, we have A %*% t(X)
== t(Y)
and A.full %*% t(X) == t(Y.full)
The list cmu contains the following:
The
routing matrix A
. The columns of this matrix
correspond to individual OD flows (the columns of X), and
its rows correspond to individual link loads (the columns
of Y).
The OD matrix X. Columns correspond to individual OD flows, and the rows correspond to observations.
The link load matrix Y. Columns of the Y matrix correspond to individual link loads, and the rows correspond to observations.
The routing
matrix A.full
. This is the complete routing matrix
before reduction for full row-rank.
The link load matrix Y.full, corresponding to A.full.
