Organizations are in search of improving network agility, but what exactly does this mean? Network agility is represented by the volume of change in the network over a period of time and is defined as the capability for software and hardware component’s to automatically configure and control itself in a complex networking ecosystem. However, organizations are still looking for ways to further improve network agility, but how do they get there? MORE

Since we are operating with 2 slaves and the rpl_semi_sync_master_wait_for_slave_count is set to 1, we’ve noticed that at least one of the slaves does acknowledge within a reasonable amount of time and the master does not switch over to asynchronous mode during temporary network disruptions. The theorem states that, in the presence of a network partition, we will have to choose either availability or consistency, but not both. MORE
What Is Network Agility? Network Agility — the volume of change in the network over a period of time — the capability for software and hardware components to automatically configure and control itself in a complex networking ecosystem. The rise of innovative efforts made by several vendors to expand and modernize network device interfaces is improving network agility and is seen with emerging technologies such as SD-WAN, SDN, NFV, and intent-based networking.
