1 OSN|M Overview
You can use the Open Services Networking Module (OSN|M) as an
expansion module installed in an expansion module slot on the rear panel
of a Switch 5500G. It provides a software and hardware platform that
can run various services. After an OSN|M is inserted into the expansion
module slot, it interacts with the switch through its two internal service
interfaces, which conforms to the software and hardware interface
specifications defined by OSN.
An OSN|M runs an independent Linux system. To configure and maintain
this system, you can log in using several methods.
You can develop and load service software on the OSN system to
implement security, management, and network optimizing applications
on the switch. This allows you to implement and run multiple application
types on the same device, therefore facilitating network and service
deployment and reducing overall cost.
