Weighted GigaStream

Weighted GigaStream provides you the ability to distribute traffic to the ports by assigning either an equal weight or a custom weight to the ports. You can assign custom weight in percentage or ratio. If a port in a weighted GigaStream goes down, the traffic from the port will be redistributed to other healthy ports in the weighted GigaStream. The port assigned with maximum weight receives more traffic than the ports assigned with lesser weight.

Weighted GigaStream is supported on the following:

■

All GigaVUE-HC Series and GigaVUE-TA Series nodes.

■

Regular tool GigaStream, regular hybrid GigaStream, and regular circuit GigaStream.

Use the Weighting and Drop Weight fields in the GigaStream configuration page to configure a weighted GigaStream. For instructions, refer to Configure Regular GigaStream.

You can also choose to rehash the traffic when you find that the traffic distribution is not ideal. When you rehash the traffic, GigaVUE‑FM reassigns the hash buckets to the ports. For example, the following table shows that the ports are assigned with sequential hash buckets:

Port	Hash Buckets
x1	1, 2, 3, 4
x3	5, 6, 7, 8
x4	9, 10, 11, 12

In such cases, the traffic distribution may not be ideal. You can choose to rehash the traffic. The following table shows how the hash buckets are reassigned when you rehash the traffic:

Port	Hash Buckets
x1	1, 4, 7, 10
x3	2, 5, 8, 11
x4	3, 6, 9, 12
