Network Switches with NDI traffic

[timothy_MTS]

Hello everyone,

Our network infrastructure is with two Core Switches (c93180) and a few stacked Access layer switches (c2960XR). We are now preparing to do some testing on making use of the NDI to transfer the video. Currently the devices that transmit the video are with fiber SFP module so I can use the c2960XR SFP ports to connect to the server. And we will prepare a separate VLAN for that.

However, as if the testing is good, the scale could be bigger than what we can afford on the c2960XR. It could be up to 20 connections from the server. There will not have enough SFP module to settle this.

In this case, is it a good practice to put this server connecting to the Core switch? Or, it could be a good time to consider adding a new set of switch(es) and then the new switches uplink to the Core Switches?

Hello @timothy_MTS 

I understand you're working with two Core Switches (C93180) and several Access Layer Switches (C2960XR), and you're preparing to test NDI video transmission using a separate VLAN......

However, if the test is successful and you need to scale up to 20 connections, the C2960XR may not have enough SFP ports. You’re considering whether to connect the server directly to the Core Switches or add new switches that uplink to the Core Switches.

Connecting Server to Core Switches

Connecting the server directly to the Core Switches (C93180) is a viable short-term solution. It offers high bandwidth and low latency, as the Core Switches are designed for high-capacity tasks. This simplifies the network by reducing the number of hops. However, ensure the Core Switches have enough capacity to handle the additional load without causing congestion or impacting performance.

Adding New Switches

For long-term scalability, adding new Access Layer Switches dedicated to video transmission might be a better approach. This distributes the load and maintains Core Switch performance. Ensure the new switches have sufficient SFP ports and uplink capacity. Although this involves extra cost and complexity, it offers greater flexibility for future expansion.

In conclusion, while connecting to the Core Switches can work for now, adding new switches is likely a more scalable and sustainable solution if you anticipate significant growth in video transmission.

Hope this will help u!
