    Network Bandwidth Usage Test

    Hello Everyone,

    We are working on a government building and part of the controls submittal requires us to provide a Network Bandwidth Usage Test Procedure.

    "The PVT Procedure shall describe a methodology to measure and trend the network bandwidth usage on the network backbone and compare it to the Bandwidth Usage Calculation submittal."

    Does anyone has any idea if there's a template i could find for this or a way to do this.

    Thanks.

    Are you supplying IT equipment for this project? Plenty of routers can tell you current bandwidth usage, but the logging of that is going to be a different story and might require third party software like Nagios which would gather and log that information from the routers.

    All of the above is way out of scope for typical building controls.

    Also typical building controls are fairly minimal on how much bandwidth they use as opposed to what's available these days.

    I'm going to assume there is a tridium driver for local bandwidth moniroring, only because it seems like there is one for everything, but I'm not aware of what it might be. And it would only give you that one device.

    Regarding point 1 pfSense will give you a little bandwidth usage chart for the past minute or so, might even be able to log it somehow. pfSense is freely available to build your own router, or can be purchased with a netgate router. Ubiquity Edgerouters can give you the current usage number, no chart. Both of these are very firmly in the network infrastructure, rarely something people want their controls vendor working with.

    Thank you Max.

    I did receive some extra information.

    Network Bandwidth Usage Calculations

    The Contractor shall perform Building Control Network Bandwidth Usage Calculations for a normally loaded and a heavily loaded control network.
    Calculations shall be performed for network traffic on the backbone.

    A heavily loaded control network is characterized as one performing the following activities simultaneously:

    a. Transmitting every point in the building indicated on Points Schedules as being available to [the UMCS][the Building Point of
    Connection (BPOC) location][a single point on the backbone that is not on a local control bus] in response to polling requests at 15-minute intervals (for trending at UMCS).

    b. Transmitting five points to [the UMCS][the Building Point of Connection (BPOC) location][a single point on the backbone that is not on a local control bus] in response to polling requests at 2-second intervals.

    c. Transmitting 100 points to [the UMCS][the Building Point of Connection (BPOC) location][a single point on the backbone that is not
    Page 44 on a local control bus] in response to polling requests at 5-second intervals.

    d. Transmitting occupancy commands from [the UMCS][the Building Point of Connection (BPOC) location][a single point on the backbone that is not on a local control bus] to every system schedule sequence in a one-minute interval.

    e. Transmitting occupancy override commands from [the UMCS][the Building Point of Connection (BPOC) location][a single point on the backbone that is not on a local control bus] to every system schedule sequence in a one-minute interval.

    A normally loaded control network is characterized as one performing the following activities simultaneously:
    a. Transmitting every point in the building indicated on Points Schedules as requiring a trend to the UMCS in response to polling requests at 15-minute intervals (for trending at UMCS).

    b. Transmitting 50 points to the UMCS in response to polling requests at 5-second intervals.

    c. Transmitting occupancy commands from the UMCS to every system scheduler sequence in a one-minute interval.

    Thanks Max.

    We are doing the controls for HVAC and it includes providing T sensors, Thermostats, Work Station etc.

    Also, I know ALC published an (old) whitepaper for this sort of thing. Ask your vendor.
