Abstract: One embodiment of the present invention provides a switch. The switch includes a multicast management module, a storage module, and a recovery module. During operation, the multicast management module represents multicast information from one or more entries of a multicast data structure in a way that the switch can derive its multicast states from the multicast information. The storage module stores the multicast information in a recovery file in a local persistent storage device. If the switch reboots, the recovery module restores the multicast states of the switch from the multicast information in the recovery file.

Abstract: Systems, methods, and non-transitory computer-readable storage media for a miscabling detection protocol. One or more switches can periodically send miscabling protocol (MCP) packets on non-fabric ports on all configured EPG VLANs. A first switch located at a network fabric receives a miscabling protocol (MCP) packet indicating an identity of an originating switch and a port number of an originating port of the MCP packet via a receiving port on the first switch, wherein the MCP packet is received from an external network connected to the receiving port, and wherein the originating switch and originating port are also located at the network fabric and connected to the external network. Based on the MCP packet, the first switch then detects a loop between the receiving port, the originating port, and the external network. Next, the first switch blocks the receiving port or the originating port in response to detecting the loop.

Abstract: Methods, apparatuses, and systems are provided for improving utilization of a communications system through various atom-based techniques for enhancing the viewing experience for Internet protocol content. Some embodiments exploit atom-based processing to determine which content atoms to broadcast (e.g., multicast) over which channels to which subscribers. Other embodiments make atom-based filtering, caching, and/or other determinations at the user terminal. For example, low-level (e.g., physical layer) filtering may be used to limit the amount of user-layer processing needed, and to facilitate delivery of content to those users most likely to desire that content. Still other embodiments allow users to create customized channels of cached content for viewing as a shared channel. Embodiments include techniques for addressing synchronization of channel content and viewing, and social networking, for subscribers to the shared channel. The shared channels may be further used to facilitate social networking among subscribers.
