Abstract

Reliability and availability considerations are discussed in this paper with special focus on `cloud based´ Mobile Switching and Application Servers (MSS and AS). Before the extensive deployment of cloud based telecom networks an essential question shall be answered: Will cloud technology ensure the `carrier grade´ requirements that are well established and proven on `legacy telecommunications´ hardware? This paper shows the possible redundancy principles and a simulation method to predict availability for `cloudified´ mobile communication network elements. As a calculation example, Nokia AS on `telco-cloud´ is presented, that combines several redundancy principles such as full protection (2N), load sharing and standby.
