Part III - WORKSHOP (Hands-on Traffic Engineering Labs)
Lab 1: Voice - Erlang B Calculator The Erlang B Calculator can be used to work out how many lines you need for a trunk group if you know the Busy Hour Traffic which the trunk group is offered.
Lab 2: Lines to IP Bandwidth Calculator The Lines and IP Bandwidth Calculator can be used to estimate the bandwidth required through an IP based network for a fixed number of voice paths.
Lab 3: Call Center Calculator Our Call Centre Calculator, which can be used to estimate how many call centre agents you require for each hour of an eight hour day, and how many trunks you need.
Lab 4: Call Minutes Calculator The Call Minutes Calculator uses the number of minutes of traffic a trunk group is offered in one day to work out the number of required lines.
Lab 5: Erlangs to VoIP Bandwidth Calculator The Erlangs and Bandwidth Calculator can be used to estimate the bandwidth which must be provided through an IP based to satisfactorily transport a given busy hour traffic level.
Lab 6: Extended Erlang B Calculator The Extended Erlang B Calculator is similar to the Erlang B Calculator but takes retries into account. It can be applied to trunk groups from which no overflow facilities exist.
Lab 7: Erlang C Calculator The Erlang C Calculator can be used to estimate how many agents are required in a call centre, if the quantity and length of incoming calls are known.
Lab 8: Engset Calculator The Engset Calculator can be used to work out how many lines you need for a trunk group if you know the Busy Hour Traffic which the trunk group is offered. It should be used instead of the Erlang B Calculator when the number of traffic sources is finite (less than ten times the number of lines).
Lab 9: IP Bandwidth Calculator The IP Bandwidth Calculator can be used to estimate the bandwidth required for data through an IP based network.
Lab 10: IP based TV and Video Bandwidth Calculator The Video Bandwidth Calculator can be used to estimate the bandwidth required for video and TV services through an IP based network.
