Abstract: Consumption-based licensing of network features based on blockchained transactions includes receiving, at a server having connectivity to a network including a plurality of network devices, a request from a particular network device of the plurality of network devices for a feature that is licensed in the network on a per-use basis. Feature-specific key blockchain elements and a feature-specific template are generated for the feature and at least one message that includes the feature-specific key blockchain elements and the feature-specific template is sent to the particular network device. The message enables the plurality of network devices to generate one or more blockchain transactions related to consumption of the feature when a usage interval associated with the feature expires.

Abstract: Techniques are presented herein for enabling performance monitoring of flows within a management and provisioning tunnel used for communicating packets between a wireless controller and wireless access point devices. A wireless controller that is configured to communicate with at least one wireless access point obtains a packet to be sent to the wireless access point for wireless transmission in a wireless network by the wireless access point. The wireless controller identifies, based on the packet, traffic session flow information associated with the packet. The wireless controller encapsulates the packet with a tunneling header that comprises the traffic session flow information and sends the encapsulated packet to the wireless access point. The tunneling header may also comprise an application identifier (ID) associated with the packet.

Abstract: In an example embodiment, an example method is provided for echo mitigation in a conference call. In this method, a test audio signal is transmitted to a conference endpoint and as a result, an echo associated with the transmittal of the test audio signal is received. One or more parameters of the echo are then identified and an echo mitigation process is selected from multiple echo mitigation processes based on the identified parameters. The selected echo mitigation process is then applied.

At least a portion of the media is analyzed to determine a media quality for the media message. The method then determines if the media quality is acceptable. If the media quality is not acceptable, then an alert may be sent regarding the media quality of the media message. For example, a caller may be prompted to re-record a media message.

Abstract: An apparatus and method of buffering a media stream is provided. The method may comprise receiving a plurality of IP packets of the media stream, each packet providing a fragment of a portion of the media stream. Thereafter, the portion of media stream may be buffered in a jitter buffer using the fragments provided by the received packets. Further, the portion of the media stream may be buffered in a replay buffer using the fragments provided by the received packets. The replay buffer may be larger than the jitter buffer and a first received fragment and a second received fragment may be combined. The second received fragment may have been discarded by the jitter buffer. A media stream may then be played back using media from the replay and/or jitter buffer.

Abstract: A method is provided in one example and includes establishing a path for a media session between a first network element and a second network element. A third network element is detected along the path. A response is received from the third network element indicating that it is capable of performing a loopback activity that involves the first network element. A test packet is communicated from the first network element to the third network element in order to evaluate characteristics associated with the media session. In more specific implementations, the response includes an indication as to a proximity of the third network element in relation to the first network element. The first network element can receive additional responses from a plurality of network elements such that the first network element generates a list of available network elements for performing loopback activities.
