Abstract: In one embodiment, a method includes receiving a first packet sent by a first node. The packet includes a first Layer 3 source address, a first Layer 3 destination address, a first Layer 2 source hardware identifier, a first Layer 2 destination hardware identifier, and a first path identifier. The first path identifier is situated between a Layer 2 header of the first packet and a Layer 3 header of the first packet. The method includes automatically determining a first port of the first network element associated with a second node. The second node is associated with the first Layer 2 destination hardware identifier. A second path identifier is automatically determined based on the first port. The first packet is prevented from being delivered to the second node in response to determining that the first path identifier and the second path identifier are different.

Abstract: A method is provided in one example embodiment that includes receiving a radio signal stream, segmenting the radio signal stream based on a control word in the radio signal stream, mapping the segmented radio signal stream to a service class, transporting the segmented radio signal stream in packets through channels over a backhaul link, and maintaining the order of the radio signal stream over the backhaul link. In more particular embodiments, the backhaul link may use a DOCSIS link, the radio signal stream can be received using a Common Public Radio Interface, and the radio signal stream may include sub-streams transported through segmented channels over the backhaul link.

Abstract: System and methods for modifying streaming data based on radio frequency information is provided. As radio transceivers transition move to a shared resource or cloud model and the existing radio transceivers are split into a baseband unit and a remote radio head, radio frequency (RF) information including power levels, encoding, data rates, and bandwidth can be provided to video optimization server. The RF information can be provided more frequently to allow real-time modifications to streaming video data. Existing protocols are reactionary in nature and perceive changing channel conditions indirectly. By providing RF information from the baseband unit on a low latency channel, modifications to the video stream can be made before an impact would be noticed at the protocol level. Also, policy information can be used to influence the changes made to streaming data in addition to the RF information.

Abstract: An example method for facilitating software defined networking for storage area networks is provided and includes dividing a control plane of a storage area network (SAN) into a centralized network control plane and a plurality of decentralized control planes, configuring network-wide SAN applications in the centralized network control plane, and configuring switch-level SAN applications in the decentralized control planes. In a specific embodiment, the network-wide SAN applications include at least one selection from a group consisting of: name server, zone server, worldwide name-virtual SAN (VSAN) mapping, device aliases, link-state routing information, principal switch selection, domain manager, and virtual local area network-VSAN mapping.
