Bandwidth requirements for 5620 SAM GUI Clients
Bandwidth requirements for 5620 SAM GUI Clients
The bandwidth specifications provided above for 5620 SAM GUI Clients are based on
the fact that information about changes in the network is forwarded to the 5620 SAM
GUI Clients. The 5620 SAM Client updates information visible to the user based on
recent changes in the network.
A few examples of network changes which will be reported to 5620 SAM include status
changes of physical equipment, status changes of Layer 2 or Layer 3 interfaces,
configuration of network elements, provisioning of new equipment or services, status
changes in services or any attributes thereof, configuration changes of routing protocols
and several others.
In situations where the frequency of changes sent to the 5620 SAM GUI is significant and
exceeds the bandwidth specification, the performance of the 5620 SAM Client will
degrade, and there is a possibility that the connection to the server will be dropped. A
5620 SAM GUI restart will be required to reconnect to the server to receive change
notifications.

Bandwidth requirements for displaying 5620 SAM GUI Clients on X displays
5620 SAM GUI Clients can be displayed remotely on terminals using the X11 protocol
for graphical displays. In these cases, it is important to ensure the bandwidth availability
between the workstation running the 5620 SAM Client and the host displaying the 5620
SAM Client be at least 1024 Kbps. Also, it is important to ensure the round-trip network
latency between these two hosts is quite low (20-30ms). To achieve acceptable
performance on bandwidth limited links, X-compression should be used by using the ssh
-XC command. If not using compression, it is recommended that the minimum bandwidth
be higher than 1024 Kbps. Situations where the available bandwidth is lower or the
network latency is higher will result in poor usability of the 5620 SAM GUI Client. A
bandwidth of 1024 Kbps will impact GUI start time and will not meet the published time
of 30s.
Extra bandwidth may be required to support the network elements described in “GNE,
Alcatel-Lucent OmniSwitch, 9471 WMM, eNodeB, and 5780 DSC considerations”
(p. 5-20)
Note that 5620 SAM GUI Client startup may be impacted when using minimum
bandwidth links.
