LONG-TERM MONITORING OF ROUTES UNAVAILABILITY FOR INFORMATION AND COMMUNICATION NETWORKS

Abstract

The article represents an approach to long-term monitoring of routes unavailability for information and communication networks based on the TCP/IP stack. The proposed approach allows the identification of the necessity of a route reconstruction or reconfiguration before QoS significantly suffers, which can be a part of a preventive maintenance strategy. Being the bases of the proposed approach, the statistical prediction techniques including the polynomial extrapolation and autoregressive integrated moving average allow to obtain prediction results with the preset probability. In addition, the proposed method allows the performance of an automatic network infrastructure and routes discovery. This work also explains the interaction between software modules of the proposed method implementation. The proposed method represented by this work is recommended to be used in the wired networks of access and aggregation/distribution where usually a few (if any) backup routes are available and, thus, it is more sensible to avoid a malfunction than to react on it after it happens.
