The SMS has replication bandwidth requirements for heartbeat, event traffic, and downloads
for digital vaccines (DVs) and upgrade packages.
- Less than 10 Kb/s bandwidth is required for heartbeat and system usage/administration operations, such as policy management.
- A minimum of 1 Mb/s bandwidth is recommended to download DVs and upgrade packages. These operations consume as much bandwidth as is available between the two systems, but headroom of about 1 Mb/s keeps the two systems reasonably synchronized.
- Event traffic requires approximately 1.5 Mb/s per 1,000 events/second.
