Software Quality Attributes -> Redundancy

 

 

AdvOSS uses different technologies in combination to achieve redundancy in the system and make sure that the redundancy is used towards availability when needed. There are many types of Redundancy needed in the system, and AdvOSS platforms handle them as explained below:

 

 

a- Storage Redundancy

All databases are redundant and use advanced multi-master replication techniques to keep up to date with each other. This ensures that there is more than one usable copy of all data which is current up to the second. Replication Architectures pose no limit to the amount of Redundancy an Operator may want to have in his system.

Moreoever , since the database clients are also AdvOSS Products therefore they make use of the Primary-Secondary Connections technology to make the transition semaless for the end clients.

Further Details are available at Multimaster Databases and Primary-Secondary Connections

 

 

b- Computation Redundancy

i. Database

In addition to Storage Redundancy, Multi-Master replication offers computation redundancy as well. Processing can be switched to secondary servers in real-time without loss of continuity.

ii. Switching and AAA

All Switching and AAA products work on a dispatcher / Serving node architecture. Dispatcher does real-time load balancing among all Serving Nodes given computational redundancy. If any Serving node goes down, processing carries on through other available nodes.Further Details are available at AdvOSS Packet Router
