GRE
GRE (Generic Routing Encapsulation) tunnel is used to carry non-IP packets
through an IP Network. Non -IP packets, that are send over the GRE tunnel, need
to be first encapsulated. Hence, ALEOS is used to configure and encapsulate
non-IP packets and transmit over IP through the GRE tunnel.
Applications
Events Reporting
Events Reporting is Sierra Wireless AirLink’s modem’s new software feature
provided via ACEmanager, that allows the users to generate reports from the
events that take place. Event Reporting Protocol is an intuitive embedded
protocol, which automatically formats the messages based on an event trigger.
The messages generated are then reported to the remote server.
Software
The Raven XT modem comes with the following software:
• AceView, the software for the Raven XT which allows you to monitor your
connections.
• The driver that forms the interface between the Raven XT and your Windows
operating system when using USB virtual Ethernet or USB virtual serial.
• The firmware that is stored in non-volatile memory and includes
ACEmanager.
The Raven XT has an embedded radio module, also made by Sierra Wireless,
Inc. There are two firmware programs on the device—one stored on the con-
troller board of the Raven XT and one on the radio module.
The firmware was loaded into the radio module and controller board when the
Raven XT was assembled. As new versions of the software and firmware are
released, they are posted at www.sierrawireless.com.
