the application can alter its behavior based upon the configuration changes.

-The openais executive uses a ring protocol and membership protocol to send messages
+The corosync executive uses a ring protocol and membership protocol to send messages
according to the semantics required by extended virtual synchrony. The ring protocol
creates a virtual ring of processors. A token is rotated around the ring of processors.
When the token is possessed by a processor, that processor may multicast messages to
larger message. Smaller messages obtain better messages per second, because the
time to send a message is not exactly the same.

+80% of CPU utilization occurs because of encryption and authentication. The corosync
can be built without encryption and authentication for those with no security
requirements and low CPU utilization requirements. Even without encryption or
authentication, under heavy load, processor utilization can reach 25% on 1.5 GHZ
CPU processors.

-The current openais executive supports 16 processors, however, support for more processors is possible by changing defines in the openais executive. This is untested, however.
+The current corosync executive supports 16 processors, however, support for more processors is possible by changing defines in the corosync executive. This is untested, however.
.SH SECURITY
The EVS library encrypts all messages sent over the network using the SOBER-128
stream cipher. The EVS library uses HMAC and SHA1 to authenticate all messages.

.SH OVERVIEW
The logsys library provides a generically usable logging and tracing system for
use by applications. It supports many features including:

-#include <openais/logsys.h>
+#include <corosync/logsys.h>
... (other #includes)
