Reliability assessment of network elements using black box testing

In this paper, we outline a procedure for quality assurance of network elements before their deployment. Software reliability is assessed using two models: a process-centric model (Musa's (1987) basic model) and a product-centric model (proposed by Hoeflin (2000)). Simultaneous use of both approaches is for sensitivity analysis of the results. In addition, we introduce the concept of deployability to measure the degree of confidence on the decision to deploy the equipment in the field.
