HMP Linux 1.2 Release Update, Rev 05 — September 2006September 2006 26
In Chapter 2, “System Requirements”, the following section is added:
2.4 Running a Demo Using a Single Channel
The default channel license provided with the HMP Linux 1.2 software relies on the
correctness of the /etc/hosts file. Invalid entries in this file will render the HMP product
non-functional with respect to the default channel license. For example:
1. 127.0.0.1 myhostname << incorrect
2. 127.0.0.1 localhost << incorrect
192.168.124.124 localhost
3. 127.0.0.1 localhost << correct
192.168.124.124 myhostname
In Chapter 3, “ Release Features”, the following information applies to the
Configurations Tested section:
•Current testing of 240 channels is performed with G.711 20 ms and 30 ms frames
only.
•Current testing of 240 channels is performed using the Intel 8254x-based gigabit
Ethernet solution. Other network interface cards may not provide optimum
performance. However, 8241, 8245, 8246, and 8247-based gigabit cards are also
expected to perform well. These cards provide superior performance by:
•Minimizing the number of interrupts needed relative to work accomplishe d.
•Reducing the frequency of all interrupts by setting the “Inte rrupt Throttling Register”
to the appropriate value.
•Accepting multiple receive packets before signaling an interrupt.
•Eliminating (or at least reducing) the need for interrupts on transmit.
•Minimizing the processing overhead associated with each interrupt.
