Network Switch a Centralized Access Approach
This paper gives a mechanism for doing authentication and authorization between managed element and server from a single database using a centralized controller which can control a multiple switches. This work allows having one or more authentication servers for the switches to authenticate against which centralizes the authentication databases, making it easier to manage switch. Moreover, switch continues to support the pre-existing local authentication which works as a fallback in case of loss of connectivity to authentication server. Command authorization on per user basis is added which makes possible to have authorization of user to execute specific commands.
