EJB-based implementation of L1VPN NMS controlled by each customer

Abstract

We propose a new service for the L1VPN (layer-1 virtual private network), in which an L1VPN customer can manage and control its own L1VPN from an end-to-end point of view. In the service, a customer can change its routing policy on the basis of a decision and set network notification policy for individual VPN users. These operations are conducted by an L1VPN NMS (network management system), which is distributed online by an L1VPN provider in EJB (enterprise java beans) format. In addition to the L1VPN NMS, EJB-based customer domain NMSs that manage individual customer domains are also delivered to individual customers. In cooperation with the provider NMS, which is for the L1VPN provider network, and the customer domain NMSs, an L1VPN NMS can update the L1VPN logical information from provider and customer domains. The L1VPN NMS receives alarm notifications from both NMSs and forwards them to IP users who are affected by the notifications. We evaluate the effect of an L1VPN on alarm notification time because swift alarm notification is critical for IP users. In addition, we evaluate the effect of deploying multiple customer domain NMSs in one Linux NMS server.
