Abstract:
A system and method provide for connectivity to multiple network operators at a given time, and sorting outgoing traffic based on criteria associated with the data and the network operators. Available networks are identified, and a mobile device attaches to a first network for communication through a first application, and also attaches to a second network for communication through a second application, without requiring detachment from the first network. Accordingly, traffic for the first application is steered through the selected first network, and traffic for the second application is steered through the second network.
Abstract:
A distributed software defined network (SDN) packet core system is configured to support a plurality of radio access technologies. The distributed SDN packet core system can include a cloud-based SDN centralized infrastructure instance and a plurality of local SDN infrastructure instances distributed in proximity to wireless access networks and radio access points thereof. The cloud-based centralized SDN infrastructure instance can be configured to handle network operations that are not latency sensitive. Each local SDN infrastructure instance can include a plurality of computer devices configured to execute a plurality of RAT specific control-plane modules and a plurality of RAT independent packet processing modules for performing latency sensitive network operations.
Abstract:
A number of requests for an alternative network location are identified, where the requests for the alternative network location are generated after failure of one or more previous requests to reach a first, previous network location as a result of a network brownout. It is determined if the number of requests for the alternative network location exceed a threshold value for a period of time, and if so, an alarm is generated.
Abstract:
An autonomous network and a corresponding routing method include determining routing paths by a controller, and providing the determined routing paths to a data packet processor located remotely from the controller. The data packet processor routes outgoing data packets, based on information from the controller, through a plurality of switches remotely from the data packet processor. Each switch includes a plurality of network interfaces. For an outgoing data packet, the data packet processor determines a network interface over which to transmit the data packet, and adds an indication of the determined network interface in a header of the data packet. The data packet processor forwards the modified data packet to the switch including the determined network interface. The switch identifies the network interface based on the indication, and transmits the outgoing data packet over the identified network interface.
Abstract:
This disclosure provides systems, methods, and apparatus for providing anycast based load balancing for a plurality of servers within a network. The network includes a domain name system (DNS) server that is configured to respond to domain name queries received from one or more clients. The DNS server maintains a set of anycast IP addresses associated with a domain name. The DNS server responds to a client's request with one or more selected anycast IP addresses from the set of anycast IP addresses. The DNS server also instructs a plurality of content servers to advertise all of the anycast IP addresses to the network. The DNS server also receives load information from each of the plurality of content servers, and instructs, based on the load information, one of the plurality of content servers to cease advertising one or more of the previously advertised anycast IP addresses.
Abstract:
Systems and methods for using radio layer information to enhance network transport protocols are provided. Channel characteristics are obtained from a radio layer in a mobile device. The channel characteristics indicate the quality of a connection between the mobile device and a base station. Based on the channel characteristics, a bandwidth of the connection between the mobile device and the base station is calculated. A server is instructed to transmit data to the mobile device at the data rate determined based on the determined bandwidth.
Abstract:
A method includes receiving one or more data packets from an external network, establishing a first data bearer when a user device connects to a first network, and establishing a second data bearer when the user device connects to a second network. The user device is configured for dual connectivity with the first network and the second network. The method also includes routing the one or more data packets through at least one of the first network or the second network to the user device to simultaneously balance network traffic load across both the first network and the second network.

Abstract:
Systems and methods are disclosed for requesting media content segments via multiple network connections. In one implementation, a processing device requests, via a first network connection, a sequential transfer of a first media content segment in a first direction. The processing device requests, via a second network connection, a sequential transfer of the first media content segment in a second direction. The processing device requests, based on a determination that the first media content segment has been received, from at least one of the first network connection or the second network connection, a second media content segment.
Abstract:
Exemplary embodiments provide techniques for specifying, on a per-service basis, (1) the peering router to which a particular network packet should be directed, and (2) the egress port that the packet should use when it leaves the peering router. One embodiment encapsulates an original packet inside an encapsulating packet. The encapsulating packet may specify, as a destination, a desired peering router in order to route the packet to a specific peering router and may specify an egress port identifier identifying a desired egress port on which the packet should be sent out from the peering router. At the peering router, the encapsulated packet may be decapsulated and the desired egress port may be retrieved. Thus, general network routing information may be overridden in favor of selected service-specific routes, allowing faster routes can be chosen for more important traffic or services.
