This paper studies the recovery from communication or node failures in network coded parallel architectures using contour approach. We propose a reciprocally efficient approach to recovery of failed communication in parallel network as Parallel Architecture Coding- Link Failure-Recovery Mechanism (PAC: LF-RM). In our precious work we have proposed PAC: LF-RM for such evolving failure circumstances in parallel network and the chance of communication failure is also evaluated. Via some comparative study on traditional approach and the proposed approach of failure recovery, we obtain a lower communication cost for failure situations using our approach. For failure recovery, we also propose a broadcast format and design a linear network coded parallel networks using contour approach to communicate in such networks. We also give numerical comparisons of our approach with other traditional recovery mechanisms to show the advantage of the proposed approach.
