A method is described and in one embodiment includes receiving at a first node in a communications network a Session Traversal Utilities for Network Address Translation ('STUN') message associated with a first flow, wherein the STUN message comprises a flow attribute including corresponding to the first flow; analyzing the flow attribute at the first node; setting policy corresponding to the first flow in the network based on the analyzing, wherein setting the policy includes using the flow attribute of the STUN message to configure a network path for the first flow in the communications network; and forwarding the STUN message to a next network node.

Techniques for informing communications networks of desired packet transport treatment

A method is described and in one embodiment includes receiving at a first node in a communications network a message associated with a first flow, wherein the message comprises a flow treatment attribute including metadata indicative of how the first flow should be treated in the network; analyzing the flow treatment attribute at the first node; setting policy for treatment of the flow in the network based on the analyzing; and forwarding the message to a next network node.

In one embodiment, a device in a network receives privatized network trace data that comprises round trip time information for hops along a communication path. The device groups the trace data into a plurality of network segments based on the round trip time information. The device calculates a segment trip time metric for one or more of the network segments based on the round trip time information associated with the one or more network segments.

Performing network topology traces with minimal data collection

In one embodiment, a first device in a network sends a Session Traversal Utilities for Network Address Translation (STUN) binding request towards an endpoint device of a media session between the first and endpoint devices. The binding request includes one or more network attribute fields. The first device receives a binding response from an intermediate node between the first and endpoint devices in the network, in response to sending the binding request towards the endpoint device. The intermediate node inserted the one or more network attribute fields into the binding response. The received binding response includes one or more metrics for the media session in the one or more network attribute fields. The first device adjusts one or more bitrates of the media session based on the one or more metrics for the media session in the received binding response.

Optimizing media bitrate with explicit network feedback on one client only

A method including: receiving, at a conference unit, a command to establish a conference call between the conference unit and another conference unit, the conference unit being connected to at least one access point and the access point being accessible by a terminal; utilizing, by the conference unit, an internet telephony protocol to setup at least one media line between the conference unit and the other conference unit; establishing at least one data channel that transmits LAN traffic between the conference unit and the other conference unit utilizing the internet telephony protocol; establishing, by the conference unit, a connection with the terminal, the terminal being part of a combined local area network; and receiving, at the conference unit, an input from the terminal via the connection to access the combined local area network.

Method and system for establishing a combined local area network (CLAN) in a conference network (CN)

In one implementation, a source endpoint and a destination endpoint communicate using multipath. A data stream may be transmitted using a primary path. The source endpoint and the destination endpoint connect through an alternative path, but before portions of the data stream are transmitted using the alternative path, the alternative path is tested using one or more disposable packets. The source endpoint sends the disposable packet of the data stream using the alternative path to the destination path and receives a transmission parameter for the disposable packet of the data stream and the alternative path.

Multipath data stream optimization

A STUN message is received at a router device in a network from a client device in the network along a network path. The STUN message is evaluated for information that indicates to the router device to modify media that is subsequently sent along the network path. If the evaluating indicates that the router device is to modify the media, the media is modified in accordance with information in the STUN message that indicates attributes of the network.

Rich media status and feedback for devices and infrastructure components using in path signaling

Techniques are provided for detecting network characteristics. At a first endpoint device configured to communicate with a second endpoint device in a network, a request is made to a relay server in a network for an address and port assignment on the relay server. The address and port assignment are obtained from the relay server, and a probing packet is sent at a first time instance to the relay server at an address and port corresponding to the address and port assignment. The first time instance is stored in a timestamp field of the probing packet. A response packet responsive to the probing packet is then received from the address and port on the relay server at a second time instance. The second time instance is stored in a timestamp field of the response packet.

Bandwidth probing messages

In one embodiment, a method includes receiving, by an endpoint from a client, an image generated by the client. The endpoint determines that the image generated by the client includes a matrix barcode. The endpoint decodes the matrix barcode to determine one or more instructions associated with text encoded within the matrix barcode. The method further includes performing the one or more instructions associated with the encoded text.
