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

A method is provided in one example and includes receiving at least one first input indicating at least one network condition associated with a first user device having a user associated therewith. The first user device has a first bearer channel established between the first user device and a gateway, and the first bearer channel has a first quality of service level. The method further includes determining whether to modify the first user device to a second quality of service level based upon the received at least one first input, and sending a first request to a first network element instructing the first network element to modify the first user device to the second quality of service level.

System and method for orchestrating policy in a mobile environment

A method is provided in one example embodiment and may include communicating information between a plurality of network function virtualized (NFV) based applications; and creating at least one service chain using at least two of the plurality of NFV-based applications based on the information communicated between the plurality NFV based applications. In some instances, the information can be communicated using border gateway protocol (BGP) exchanges between the NFV-based applications. In some instances, the information can include at least one of: next-hop address information for one or more ingress points of a particular NFV-based application; one or more capabilities by which a particular NFV-based application can receive data on one or more ingress points; and a method by which one or more egress points of a previous NFV-based application in a particular service chain is to perform load balancing for a subsequent NFV-based application in the particular service chain.

System and method to chain distributed applications in a network environment

In one embodiment, a method comprises identifying, by an orchestrator executed by a physical machine, a plurality of virtualized network functions required for implementation of a virtualized network service for a customer, each virtualized network function having a corresponding and distinct virtualized container specifying attributes for defining execution of the corresponding virtualized network function within one or more physical machines; and setting by the orchestrator an interdependency indicator within each virtualized container based on association with the virtualized network service, enabling identification of each of the virtualized network functions as interdependent for coordinated execution of the virtualized network service.

Systems and methods for performing content control in a mobile network using an out-of-band signaling channel are disclosed. In one embodiment, content control may be performed on a network device by collecting usage data for media consumption and caching from a mobile device via an out-of-band channel; receiving the usage data at an intermediate device via the out-of-band channel; building a predictive user profile based on the usage data; determining a schedule for downloading content from one or more media servers based on at least the predictive user profile; and sending instructions to perform one of time-shifting or pre-positioning to the one or more media servers according to the schedule for downloading content via an out-of-band channel.

Out-of-band signaling and device-based content control

An example method is provided in one example embodiment and can include obtaining, within a radio access network, a channel state for a data channel associated with a mobile terminal; including the channel state in a differentiated services (diffserv) marking within an Internet Protocol (IP) header of at least one IP packet associated with the mobile terminal; and transmitting the at least one IP packet including the IP header having the diffserv marking toward a packet data network.

A first virtual machine is established in a virtual private service chain to provide a first network service to virtual private service chain traffic. A second virtual machine is also established the virtual private service chain to provide a second network service to the virtual private service chain traffic. The virtual private service chain traffic is encrypted for transmission within the virtual private service chain from the first virtual machine to the second virtual machine, wherein the encryption uses a key shared by the first and second virtual machines.

End-to-end security for virtual private service chains

In one embodiment, a method comprises receiving by an apparatus, via a wide area network, a request for deployment of a selected one of available virtualized network services advertised by the apparatus, the request identifying a host service provider to deploy the one virtualized network service; identifying, by the apparatus, virtualized network functions required by the host service provider for implementation of the one virtualized network service, each virtualized network function having a corresponding and distinct virtualized container specifying attributes for defining execution of the corresponding virtualized network function within one or more physical machines of the host service provider; and sending to the host service provider, by the apparatus, a service container specifying instructions for deploying the one virtualized network service, the service container including instructions for deploying the virtualized network functions as interdependent for implementation of the one virtualized network service by the host service provider.

A data flow is received from a mobile network relating to a mobile subscriber. Subscriber data is received for the subscriber identifying a service path corresponding to the subscriber and at least one service policy corresponding to the subscriber, the service path including a set of network service nodes in a plurality of network service nodes. Packets of the data flow are routed according to the service path, the packets corresponding to a request for a resource. At least one packet is appended with service header data identifying the service policy. Each service node performs at least one service based on received request data, each service node in the set of service nodes performing a service defined in a service subscription of the subscriber. At least one particular service node in the set of network service nodes performs a particular service based at least in part on the service policy.

Mobile service routing in a network environment

A method is provided in one example and includes receiving a request for a service from a requestor, an determining at least a first network element and at least a second network element required to satisfy the request from among a plurality of network elements. The method further includes triggering a coordinating of a work flow between the first network element and the second network element responsive to the request. The method still further includes translating communication messages exchanged between the first network element and the second network element from a first communication protocol format and a second communication protocol format.

Orchestrating mobile data networks in a network environment

Network operators are striving to find ways to provide stable video services amid a rapid increase in video data traffic. In order to provide stable video services with constrained network resources, network operators attempted to deploy multiple communication networks in parallel. However, network operators failed to effectively balance data traffic across parallel communication networks. This disclosure provides systems and methods for effectively balancing data traffic across parallel communication networks.
