client-to-server communication is only used for signaling and broadcasting,
512 kbps is sufficient on these channels as well.
The recommendations in this document are for an in-band management
network that is used exclusively for management of the Nimbra nodes. No
consideration has been taken for allowing other traffic.
To limit the load on the DLE server, there is a recommended maximum of
DLE clients in one segment per server.
To limit the load on the gateway, there is recommended maximum number of
nodes that shall have its traffic routed through the gateway.
For availability reasons, when a single DLE server is used, it is recommended
that the gateway for a DLE segment is located on the same node as the DLE
server.
