Abstract

A method and system for network protocol agnostic detection and correction of network related errors is disclosed. The method and system includes regularly transmitting pre-defined data packets between two nodes through multiple paths in a network. Data packets received through the multiple paths are analyzed to detect errors and one or more corresponding faulty paths are identified.

Method and System for Network Protocol Agnostic Detection and Correction of Network Related Errors and Faults

Disclosed is a method and system for network protocol agnostic detection and correction of network related errors and faults. The method and system includes a plurality of Network Watch-Dog Appliances (NWA) distributed across a network. Each NWA regularly transmits pre-defined data packets to another NWA through multiple paths in the network. By analyzing the correctness of data packets received through the multiple paths, one or more faulty paths are identified. Further, one or more network devices on the one or more fault paths are also identified by performing a root cause analysis.

The figure shows an exemplary implementation of the disclosed method and system in a network. The network is comprised of, but is not limited to, a Core Autonomous System (CAS), one or more Service Autonomous Systems (SAS) and User Autonomous Systems (UAS). The CAS includes core routers and switches which provide the backbone for the one or more SAS and UAS. The one or more SAS and UAS are linked to the CAS via edge routers. Each SAS includes a corresponding set of network routers and switches which provide the network infrastructure associated with specific business functions such as, CRM functions of a call center. Similarly, each UAS is linked to the CAS via edge routers and switches which provide the network infrastructure associated with specific set of end users such as sales representatives working from virtual offices (home offices) across a country.

Further, according to the method and system, a plurality of NWAs are distributed in the network at strategic locations as shown in the figure. A NWA may be a software application running on a server. Alternatively, a NWA may be a dedicated hardware unit. Further, between any two...
