cmu: CMU data from Blocker & Airoldi (2011)
Description
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.
Objects
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)Variables
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.
