Abstract: Systems and methods for mediating an audio source during a meeting are provided. An active audio source is identified and mapped to instances connected to a communications and collaboration platform to determine a mapped instance. An audio signal device is determined from multiple devices for capturing audio from the active audio source. An audio system is configured to manipulate an active audio signal from the audio signal device via the mapped instance. In some cases, upon identifying a new active audio source, a new mapped instance is determined corresponding to the new active audio source.

Abstract: A network node comprises at least one data plane processor (101) for handling data packets of a first type (144) and for redirecting and rate-limiting data packets of a second type (142). A control plane processor (102) in the network node handles the data packets of a second type (142) redirected by the data plane processor (101). In order to protect the control plane processor (102) against overload, e.g. caused by Denial of Service (DoS) attacks, individual flows of data packets of the second type are identified for enhanced rate-limiting by the data plane processor (101).

Abstract: A network node able to receive, process and forward data packets, has a first stage data plane packet classifier (111) supporting basic services initially deployed and a later insertable second stage data plane packet classifier (121) supporting more advanced services deployed afterwards.
