6 Introduction

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.
