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.
