A failure in a telecommunications network, such as the loss of a link or a node, can occur for a variety of reasons. Accidental cable cuts, hardware malfunctions, software errors, natural disasters (e.g., fire), and operator mistakes are common causes of failures in Africa (e.g., incorrect maintenance). Because many of the causes of failure are outside the control of developing-country telecom operators, there is growing interest in the design of survivable networks. With the telecommunications network gaining traction, it is critical that telecommunications networkrelated issues such as node-to-node failures be resolved as soon as possible in order tAbstract
o maximize network resource utilization while minimizing failure rate. Many researches have been done on single failure points in telecommunications network, but very little on multiple network failures. This study suggests an Ant Colony System (ACS) survivability model based on capacity effectiveness and quick restoration to quickly resolve multiple node failure problems to improve service quality. The swarm model's resilience was tested using a nodeto-node failure at the network's edges. Along with its working path, each communication flow seeks a survival path in order to protect multiple intermediate node-to-node failures. The survival solution path from this scenario demonstrates that the proposed swarm technology is feasible for current business applications in Africa that
require high speed/broadband networks
