Abstract: Some implementations may provide a method for application sharing over a network that includes: (i) initiating, by a first computing device, a sharing of an application between the first computing device and a second computing device, the application having a window displaying contents and the first computing device in communication with the second computing device over the network; (ii) transmitting, from the first computing device to the second computing device, data encoding the contents being displayed in the window of the application; (iii) determining whether the contents being displayed in the window of the application have been updated; (iv) in response to determining that the contents have not been updated, pre-fetching by the first computing device, at least one snap-shot of the window with contents predicted to be displayed; and (v) transmitting, from the first computing device to the second computing device, data encoding the predicted contents.

Abstract: Embodiments of systems and methods for signaling chroma information for a picture in a compressed video stream are provided.

Abstract: A method for tracing communications includes receiving trace criteria from a first remote element and determining whether a call signaling message matches the trace criteria. The method includes attaching a trace tag to the call signaling message, if the call signaling message matches the trace criteria. The method further includes transmitting the call signaling message to a second remote element.

Abstract: Methods, apparatuses and systems directed to detecting address spoofing in wireless networks by, after receiving a wireless management frame, transmitting verification messages to determine whether a given wireless node (e.g., a wireless access point, or wireless client) has legitimately lost its connection state.
