A context-driven publication option is received over a network at an adaptive publish subscribe broker from a publishing network device. The context driven publication options are presented over the network to a subscribing network device. A selection of a context-driven subscription is received over the network at the adaptive publish/subscribe broker from the subscribing network device. A publication configured for network management and operations is received at the adaptive publish/subscribe broker. Publications are filtered at the adaptive publish/subscribe broker for the subscribing network device according to the selection of the context-driven subscription.

Adaptive publish/subscribe system

Techniques are provided herein for establishing at a network management server a presence on a network. A presence associated with one or more managed devices on the network is detected. An instant messaging (IM) session is established with the one or more managed devices. The IM session forms a virtual chat room for performing a management function on the one or more managed devices, and IM messages are sent that are configured to perform the management function on the one or more managed devices. Techniques are also provided herein for establishing on a network an enriched presence by a network management server that is configured to perform a management function via a presence function of a messaging and presence protocol.

Messaging and presence protocol as a configuration and management bus for embedded devices

An example embodiment may include an apparatus comprising a message buffer to receive messages from a voice over packet endpoint if impairments in a media stream pass a threshold, and a processor coupled with the message buffer, the processor to determine changes to media characteristics for the voice over packet endpoint in relation to the impairments and to signal the voice over packet endpoints to adjust media characteristics of the media stream in both directions. Another example embodiment may be a method comprising monitoring a voice over packet media stream for impairments, computing Voice over packet quality metrics based on the impairments, sending or receiving the Voice over packet quality metrics to or from a session peer, when a threshold is crossed for the Voice over packet quality metrics, sending an event notification to a central entity, and changing media characteristics of the voice over packet media stream in relation to the impairments as directed by the central entity.

Central entity to adjust redundancy and error correction on RTP sessions

In one embodiment, a router examines an incoming packet for a flow monitoring request. The router may examine every packet for the flow monitoring request, or preferably may only examine packets including a lifetime value indicating that the packet should be dropped and not forwarded or may only examine packets having a predetermined message format. When the flow monitoring request is included, the router performs detailed flow analysis or other monitoring according to the flow monitoring request.
