Abstract: A method, system, medium and a lightweight computing framework are provided for active network measurements. A communication network having links that connect a collection of client devices that utilize the computing framework to generate probe streams, receive network data associated with one or more network measurements, and to analyze the network data. The probe streams are generated based on a configuration file. The configuration file implements one or more network measurements and is defined in a scripting language. Additionally, the probe streams collect network data, and the computing framework utilizes the network data to determine link properties along one or more communication paths and to generate additional probe streams when specified conditions are satisfied.

Abstract: A method, medium, and wireless system are provided for scheduling access terminals to prevent starvation of access terminals connected to a communication network when one or more recently-connected access terminals having limited historical information about their channel conditions request time slots to initiate network communications. The wireless system includes access terminals and base stations that communicate over the communication network. The access terminals measure channel conditions associated with communications to the base station and transmit requests that specify a desired communication rate to the base station. The base stations receive the requests from each access terminal and select an access terminal to communicate during a subsequent time slot based on, among other things, the channel conditions and weighted average functions of the communication rate corresponding to the access terminal.

Abstract: An identification system comprises a communication interface. The communication interface is configured to receive from a mobile device a registration request to initiate an access session between the mobile device and a communication network, wherein the registration request comprises a device identifier that identifies the mobile device. In response to the registration request, the communication interface is configured to transfer a packet address to the mobile device, wherein the mobile device transfers a service request for a service on the communication network during the access session, wherein the service request includes the packet address. The communication interface is configured to receive an identification request transferred from an authentication system in response to the service request, wherein the identification request indicates the packet address.

Abstract: A method, medium, and wireless system are provided for scheduling access terminals to prevent starvation of other access terminals connected to a communication network. The wireless system includes access terminals and base stations that are configured with a first wireless scheduler and a parallel wireless scheduler that select access terminals to communicate during specified time slots. The access terminals may measure channel conditions associated with communications to the base station and transmit requests that specify a desired communication rate to the base station. The first and parallel wireless schedulers on each base station receive the requests from each access terminal and select an access terminal to communicate during a subsequent time slot that may be based on, for example, the channel conditions and weighted average functions of the communication rates—corresponding to the access terminal—generated by the first and parallel wireless schedulers.

One or more of the discovered external interfaces are selected as selected external interfaces. The selected interfaces are connected to a wireless device. The selected interfaces are used as primary interfaces subject to a security policy.

Abstract: An embodiment of the current invention is directed to determining that a wireless-service subscriber using a given mobile computing device is likely to transition to another provider (“to churn”). A list of mobile computing devices that have communicated with the given mobile computing device is determined. A relationship-strength value for each mobile computing device in the list is determined. A risk value of the given mobile computing device is determined based on the relationship-strength values of each of the mobile computing devices in the list that have churned. If the risk value is not greater than a risk value threshold, the given mobile computing device is not likely to churn. If the risk value is greater than the risk value threshold, the given mobile computing device is likely to churn.

Abstract: Methods, systems, and media are provided for the improved efficiency in bandwidth usage for transmitting repeated packets in a manner that is transparent to users. Fast, in-network per-packet caches (INPPC) at each node of a transmission retain packets for a configurable period of time or a number of packets. Rather than retransmit data from a first node to a second node within the time period for retention, an identifier is sent. The identifier allows the receiving node to access the first packet still in cache memory and reduces the size of the transmission, thereby optimizing bandwidth usage. Signatures that allow for efficient determination of packet redundancy, such as hashes, can be used. Accordingly, less bandwidth is utilized for repeated transmissions, such as transmission control protocol (TCP) retransmissions, or users accessing the same content within close proximity both physically and temporally.

Abstract: Media and methods are provided for constructing data structures associating data segments in packets with reference identifiers to optimize bandwidth usage within a network during transmission. In one embodiment, a data structure is initialized to contain no data. A minimum length of a data segment to be examined is determined. For each packet in the transmission, data segments of the packet are examined. Data segments are added to the data structure as necessary. Examination is repeated along with an appropriate addition until the packet contains less data than a segment of the minimum length and further continued until all packets are examined. The data structure is constructed associating the portions of the packet and respective reference identifiers. In certain embodiments, the count can be a total count of frequently occurring segments, the count of unique segments or the count of packets containing unique segments. In other embodiments, the construction is accomplished by a compression library.
