A method and apparatus for protecting privacy in power line communication (PLC) networks. Data transmitted on a PLC network is encrypted according to a network key and can be properly received only by registered devices that have the proper network ID and network key value so that proper decryption can be performed. According to the invention a streaming media device is provided with a compatible network ID and network key during a registration process facilitated by coupling the device (applicant) to a direct power line connection associated with another device (administrator). The network key, and optionally network ID, are then shared over the direct connection without being distributed over the PLC network at large. By way of example, the data is prevented from being distributed across the PLC network in response to using selectable filtering of PLC data, and preferably a secure data communication mechanism, such as public-private key encoding.

A real-time collaborative graphics application and method (such as Microsoft® Visio®) that runs on top of a collaborative networking platform (such as Microsoft® ConferenceXP) and provides real-time collaboration. The real-time collaborative graphics application and method personalizes local objects created by a local to readily distinguish them from remote objects created by remote users. Identifiers are used to allow the authorship of an object to be easily determined by all users. Local objects, remote objects, and a combination of the two can be moved and manipulated by any users. A local user may avoid sharing his local objects with remote users. Moreover, a local user can decide to hide remote objects created by remote users. If at a later time the local user decides to once again view the hidden remote objects, all updates since the remote shapes were hidden are automatically updated at the local user's document.

A compute node with multiple transfer processes that share an Infiniband connection to send and receive messages across a network. Transfer processes are first associated with an Infiniband queue pair (QP) connection. Then send message commands associated with a transfer process are issued. This causes an Infiniband message to be generated and sent, via the QP connection, to a remote compute node corresponding to the QP. Send message commands associated with another process are also issued. This causes another Infiniband message to be generated and sent, via the same QP connection, to the same remote compute node. As mentioned, multiple processes may receive network messages received via a shared QP connection. A transfer process on a receiving compute node receives a network message through a QP connection using a receive queue. A second transfer process receives another message through the same QP connection using another receive queue.

A WebRTC-compliant media server avoids sharing the SSRCs of passive participants (namely, the video viewers who do not send video) by intercepting feedback packets (issued from the viewers) on the server side, modifying those packets, and then transmitting the modified packets back to the sender such that, when the sender receives these feedback packets, the sender treats the packets as if they were sent by a known SSRC. Preferably, the known SSRC is one that is associated with a single SSRC (e.g., a dummy or surrogate SSRC, or a technical SSRC, in either event that was previously shared with the video sender). The sender knows how to handle these packets and can then send the desired answer to the viewer(s) to maintain the conference stable and operational even as the number of participants grows and exceeds the SSRC peer limitations.
