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.

Coordinating video delivery with radio frequency conditions

According to one embodiment, a system includes one or more memory units for storing an Address Resolution Protocol (ARP) table. The system further includes one or more processors. The processors receive, from a routing protocol, an Internet Protocol (IP)-Media Access Control (MAC) address pair for a first host computer. The processors further populate the ARP table with the IP-MAC address pair for the first host computer.

System and method for facilitating communication

In one embodiment, a system includes an interface configured to receive a first request sent from a first customer for a first service provided by a first service provider, the first request being of a first type. The system also includes at least one processor configured to determine a first set of configuration parameters from a first policy associated with the first service provider in response to receiving the first request. The at least one processor also causes a node associated with the first service provider to provide the first service in response to receiving the first request using the first set of configuration parameters.

System and method for management of network-based services

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.

System and method for transporting digital radio signal streams in a small cell network environment

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.

System and method for routing using path identifiers

A method is provided in example embodiments that include receiving a radio signal stream and segmenting the radio signal stream into segments. The segments may be packetized and transported in packets over a pseudowire in a packet-switched network. The radio signal stream can be reconstructed from the segments. In more particular embodiments, the pseudowire may be a multi-protocol label switching pseudowire or a layer 2 tunneling protocol pseudowire, for example. In yet other specific example embodiments, the radio signal stream may be received using a common public radio interface or a femtocell application programming interface.
