Mathematical Based Model on Survivability for WDM Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
Survivability is a new field of research, and is viewed by many as distinct from the traditional areas of security and fault-tolerance. Survivability is the ability of any system to continuously withstand its adequate performance and minimizing the impact of faults, failures and accidents. In the present competitive world of Information Technology where innovation is the key to the sustainability, new systems have to be designed for survivability - capability to serve the purpose in a timely manner and committed Quality of Services (QoS) continuously, striving for the decrease in failures and accidents in the presence of various failure scenarios. The common methods for finding the Survivability of an Information System are ELF (excess loss due to failure), availability model and MRM (Markov reward model). For the application of the above said tool it is assumed that the basic understanding of network topology and link capacity is known in advance. Link represents a fibre in the WDM network and capacity of the link represents the number of wavelength in the link. In this research paper author has made an attempt to find the ELF by using defined capacity and its flow. After finding ELF, availability analysis of each link has been done and Link has been combined with MRM model to evaluate the survivability.
