AI Technical Summary

Benefits of technology

This approach enables better management of VPNs by accurately inferring services and performance, providing a more comprehensive view of network quality compared to traditional methods that rely solely on single edge router performance.

Problems solved by technology

The diverse nature of the hardware and protocols makes integration and network management a true challenge.
Moreover, without effective management tools, service providers offering VPN services have difficulty managing their VPNs to the degree necessary to guarantee quality of service (QoS) contracts with their customers.

Embodiment Construction

[0031]Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings and described in the specification. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0032]FIG. 1 depicts an exemplary network environment 1000 consistent with one embodiment of the present invention. Referring to FIG. 1, the network environment 1000 includes one or more nodes A-C 150-152 connected by a communication channel 120 to an Intelligent Network Element (INE) 170 and a Network Management System (NMS) 175, all of which will be described in greater detail below.

[0033]Each of nodes A-C 150-152 represents a point on the network and may be embodied as a data processor, such as a router, a switch, a gateway, or any other communication or data processing device.

[0034]Communication channel 120 may function as a communication network (or links) and may include, alone or in any s...

Abstract

A method and system are configured to infer one or more virtual private network (VPN) services within a physical network. Topologically relevant network information is received for the physical network with regard to nodes, interfaces, connections, and protocols, and the existence of each virtual private network service is inferred based on the stored network topology information. Network objects are also inferred, including routed paths, label switched paths, Internet Protocol Security (IPSec) tunnels, and Layer Two Tunneling Protocol (L2TP) tunnels.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional application of U.S. application Ser. No. 10 / 845,517, filed 14 May 2004, and claims the benefit of U.S. provisional patent application 60 / 491,566. filed 1 Aug. 2003, the contents of which is incorporated by reference herein.I. FIELD OF THE INVENTION[0002]The present invention generally relates to communication systems and, in particular, to systems and methods for managing networks.II. BACKGROUND AND MATERIAL INFORMATION[0003]Because of the Internet's global reach, the Internet has become a universal communications medium for businesses. With distance-independent rates and flat fees, the cost of communicating over the Internet is drastically cheaper when compared to the cost of the traditional public switched telephone network (PSTN). Indeed, businesses are rapidly deploying all of their communications to the Internet, including voice traffic, which has been the exclusive domain of the PSTN.[0004]With the a...
