Bandwidth requirements for 5620 SAM Cflowd Auxiliary
Bandwidth usage characterization
5620 SAM Server to a 5620 Cflowd Auxiliary
This is for Network Snapshot Transfer (FTP/SFTP) By default this
operation should only occur weekly if the SAM Server and 5620
SAM Cflowd Auxiliary Server remain in sync. The amount of
bandwidth required is dependent on network size.
Bandwidth requirement will depend upon network size, which
determines the network extraction file size, and the desired time
complete the file transfer from the SAM Server to the Cflowd
Auxiliary
7750 SR(s) to 5620 SAM Cflowd Auxiliary
In the case of Redundant 5620 SAM Cflowd Auxiliary Servers the
amount of dedicated bandwidth is required for each Cflowd
Auxiliary.
40 Mbps per 20,000 flows per second
5620 SAM Cflowd Auxiliary to IPDR file storage server
Approximate amount of Stats per a 1 MB IPDR Stats File: 2,560
TCP PERF statistics (all counters) or, 3,174 RTP statistics (all
counters) or, 9,318 Comprehensive statistics (all counters) or
9,830 Volume statistics (all counters) In the case of Redundant
5620 SAM Cflowd Auxiliary Servers, the amount of dedicated
bandwidth calculated on the right is for each 5620 SAM Cflowd
Auxiliary Server to the workstation where IPDR files are being
transferred.
Use the information on the left to calculate the amount of data
generated for the expected Statistics. Use this to calculate the time
to transfer at a given bandwidth. The total time must be less than
50% of collection interval. For example – if 1GB of IPDR files
are expected per interval, and the collection interval is 5min, a 45
Mbps connection will take 3min,2sec to transfer. This is more than
50% and a larger network connection is required.
5620 SAM bandwidth requirements for communicating with
network elements
5620 SAM bandwidth requirements for communicating with network elements
In order to effectively manage the network, 5620 SAM must have access to sufficient
bandwidth between the 5620 SAM Server(s), 5620 SAM Auxiliary(s) and the network
elements.
This bandwidth will be used to carry the management traffic between 5620 SAM and the
network element. The following table describes the bandwidth requirements for a
particular network element.
