Description
Technical field
The present embodiments relate to the communications fields, and in particular to a kind of appraisal procedure and dress of the deployment of carrier class application cloudization
It sets.
Background technique
Conventional telecommunications network element mainly realizes high availability by modes such as configuring redundancy boards inside equipment, and internal board is superfluous
Remaining configuration, fault detection and real-time reversion realization mechanism etc. are all the privately owned solutions of producer, and different manufacturers realize that framework is different.
Operator does not need to be concerned about specific implementation, it is only necessary to conventional network elements proposition reliabilty and availability requirement index, and
It is verified in test and application.
It is defined according to related specifications, the calculation formula of system availability is as follows:
T is the time interval of observation；
Wherein, MTBF is average time between failures (the Mean Time Between Failures)；
MTTR is mean failure rate recovery time (the Mean Time To Repair).
Singlepoint devices approve- useful index can be effectively improved by shortening MTTR；Improve MTBF, i.e. it non-failure operation time, can also be with
Improve singlepoint devices approve- useful index.
