Improving network availability is critically linked to the business success of any service provider. A December 2004 survey of European and North American service providers by research group Infonetics revealed that their top three business priorities were revenue growth, profitability and competition. 1 Revenue growth will come largely from deploying value add services such as Triple Play real time services (IPTV, VoD and VoIP), mission critical business applications and VPN. These services place stringent availability demands on the network to meet the user service expectation and work as well as the mechanisms they replace. For example the PSTN service is renowned for its “five nines” reliability corresponding to less than five minutes of outage per year. 2 Expense management (capital and operating) is crucial to business profitability.
Service providers are moving aggressively to rationalize network services onto a converged IP/MPLS infrastructure, eliminating the need for multiple networks and redundant infrastructure. As a result, the converged infrastructure will be responsible for an ever increasing revenue load. To protect against highly critical service outages that greatly impact the bottom line, it must be reliable and support additional capabilities such as hitless in-service upgrades. |
