approach is adopted, the lightpath release latency is approximately
126 to 128 ms for flows 1 to 4, which is slightly longer than that of
the active approach. e reason for this is that, compared with the
active approach, the packet (request) propagation latency from the cli-
ent to the Nox, the packet processing latency in the Nox, as well as the
OpenFlow signaling latency among the Nox and each OFA are added
for overall path release latency.
When the network becomes more complex, the path setup latency
by using both the sequential and delayed approaches will increase
accordingly because of the longer processing time in the Nox controller
for RWA computation and the longer ...
