Data unit retransmission
A source node may send a first data unit to a destination node. To send the first data unit, the source node may transmit a modulation pattern over a transmission medium. In some cases, particular data units may correspond to modulation patterns with features that cause errors in transmission. The source node may receive an indication of an error from the destination node. To avoid repeated errors the retransmission, coding circuitry at the source node may alter data within the first data unit to generate a retransmission data unit. The alteration may result in the retransmission data unit corresponding to a modulation pattern different from that of the first data unit. The new modulation pattern may lack the error causing features and reduce the chance of repeated errors. |

Collecting and correlating microphone data from multiple co-located clients, and constructing 3D sound profile of a room
An overlay network platform facilitates a multi-party conference. End users participate in the conference using client-based web browser software, and using a protocol such as WebRTC. According to this disclosure, an enhanced “audio” experience for the conference is providing by collecting and correlating microphone data from multiple co-located clients, and then constructing (at the platform) a three-dimensional (3D) sound profile of the room in which the clients are co-located. By processing in the platform (as opposed to locally at each client), the approach enables platform-side creation of an ad-hoc, high quality microphone array that identifies the relative positions and orientations of the microphones that are being used by the clients. Individual audio streams received from the microphones are combined, and the relative position information (of the individual microphones) is used to render a single audio stream that represents a high quality recording of the audio in the common physical space. Other clients in the conference request, receive and play back this high quality stream to obtain a high-fidelity 3D representation of the audio as if they are physically present in the room. |

Externally initiated application session endpoint migration
In storage networks (e.g., SAN and NAS), various reasons can arise for migrating an application layer communication session endpoint to a different host. To achieve scalability and robustness, the migration can be enacted externally and carried out at a middlebox at the transport layer. When a migration is triggered to migrate an application layer communication session endpoint from a host A to a host B, the middlebox coordinates network address translation with a transport protocol reset mechanism to switch the connection to host B and close the connection on host A with minimal disruption to the non-migrating application layer communication session endpoint using the connection. At the application layer, the non-migrating application layer communication session endpoint will initiate a new connection in response to detecting the reset, and retry any operation that was aborted as a result of the connection switch. |
