Chapter 12 Cisco Transport Controller Operation
12.3 PC and UNIX Workstation Requirements
Note To avoid network performance issues, Cisco recommends managing a maximum of 50 nodes
concurrently with CTC. The 50 nodes can be on a single DCC or split across multiple DCCs. Cisco does
not recommend running multiple CTC sessions when managing two or more large networks.
To manage more than 50 nodes, Cisco recommends using Cisco Transport Manager (CTM). If you do
use CTC to manage more than 50 nodes, you can improve performance by adjusting the heap size; see
the “General Troubleshooting” chapter of the Cisco ONS 15454 DWDM Troubleshooting Guide. You
can also create login node groups; see the “Connect the PC and Log Into the GUI” chapter of the
Cisco ONS 15454 DWDM Procedure Guide.
Table 12-2 lists the requirements for PCs and UNIX workstations. In addition to the JRE, the Java
plug-in is also included on the ONS 15454 software CD.

Table 12-2 Computer Requirements for CTC
Area Requirements Notes
Processor
(PC only)
Pentium 4 processor or equivalent A faster CPU is recommended if your
workstation runs multiple applications
or if CTC manages a network with a
large number of nodes and circuits.
RAM 512 MB RAM or more A minimum of 1 GB is recommended if
your workstation runs multiple
applications or if CTC manages a
network with a large number of nodes
and circuits.
Hard drive 20 GB hard drive with 100MB of free space
required
CTC application files are downloaded
from the TCC2/TCC2P to your
computer. These files occupy around
100MB (250MB to be safer) or more
space depending on the number of
versions in the network.
