“…Reference [2] proposed a new concept of customised levels of network availability, where the customer can request different grades of service protection at a related cost premium. His concept considered different telecommunication services, the physical topologies of public telecommunication transport highway networks, the notions of traffic segregation, path diversity and hierarchical restoration.…”

The increasing demand by customers and the exponential growth in the telecommunication services in Ghana require a reliable telecommunication networks. To improve on the satisfaction of customers, it is incumbent on telecommunication network operators to ensure network availability. Designing resilient networks with low downtime and low recovery time is of paramount importance. This study describes a data set of daily outage measurement collected at the Network Operation Centre (NOC) from January 2012 to December 2012. A statistical analysis of the data was done to model telecommunication network availability pattern. Following the Box-Jenkins approach, Autoregressive Integrated Moving Average (ARIMA) was employed to analyze daily network outage. The study was mainly intended to forecast the telecommunication network outage duration in Ghana. The steps of model identification, parameter estimation, and diagnostic checking are performed as recommended. A model-selection strategy based on the corrected Akaike Information Criterion (AICc), Bayesian Information Criterion and Akaike Information Criterion (AIC) are adopted to determine the correct model specification. The results of the study indicate that ARIMA (2, 0, 2) model is suitable in predicting the network outage of telecommunication networks. Using five statistical indicators, namely, Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE), Mean Square Error (MSE), Mean Percentage Error (MPE) and Mean Absolute Error (MAE), the prediction accuracy of the proposed model is compared with the accuracies obtained with other results. The results showed that the outages and recovery time of a telecommunication network can be predicted which will help in fault management, network planning and optimization.

Since high availability requirements are expected to increase in the B-ISDN era, adequate methods are needed, which allow network designers and operators to outline the relation between available network resources and actual traffic demands on one hand and the reachable availability (performance index) for either the whole network or individual virtual path connections on the other hand. This paper suggests a simple and thus fast method for deriving the symbolic expression of the performance index in a compact form, from which a "capacity related reliability polynom" may easily he derived. Since the capacity of several subnetworks must be computed taking re-routing capability into account, an efficient procedure for capacity determination is also suggested. An example illustrates the procedure and particularly points out the effect of both resource sharing and VP bandwidth control schemes on the performance index.
