Abstract: Provided is a content delivery method and architecture for ways to improve the caching of content at one or more content providing devices of a Content Delivery Network (CDN). In particular, systems and methods are disclosed that vary the requirements to store resources or content within a caching device using a dynamic popularity threshold. This popularity threshold may be varied based on a measured fullness of the storage capacity of the cache device. In another example, the dynamic popularity threshold may be further varied based on a cache pressure, which is an indication of how often the cache replaces stored items with new items. The adjustment to the popularity threshold for caching particular content at the caching device may thus be based on a number of requests for content received at the device to tune the caching procedure for a particular region of the CDN.

Abstract: An automatic provisioning and configuration system for threat mitigation may be provided. Hardware and software resources may be automatically configured to designate a return path for forwarding clean data packets to a target network. A return path from a scrubbing center to the target network may be selected and configured, for example, based on the geographic location of the scrubbing center and information regarding available capacity of the return path to the target network, among other information. The system may provide for selection a list of Internet circuits already used by the customer. The system may also perform a set of dynamic checks to determine whether one or more of the Internet circuits are eligible for use for the return traffic.

Abstract: Aspects of the present disclosure involve systems and methods for a collaboration conferencing system to track a total number of concurrently utilized ports across any number of conferencing bridges of the network for a particular customer and one or more billing actions may occur based on this tracking. This may result in an alternate billing option for the customer's use of the system. Further, a telecommunications network administrator may provide access to the collaboration conferencing system based on a total number of concurrently utilized ports rather than on a per conference or per minute basis. With the information of the number of purchased ports by the customer, the administrator may more accurately predict an available capacity for the collaboration conferencing system needed to support all of the users of the system and the potential collaboration conferences.

Abstract: Novel tools and techniques are provided for implementing dynamic border gateway protocol (“BGP”) host route generation based on domain name system (“DNS”) resolution. In various embodiments, a computing system may receive, from a user device via a first network, a request to establish a communications link with an external device via a second network that is separate from the first network, based on a first uniform resource identifier (“URI”) indicative of a network location of the external device. The computing system may query a DNS resolver for an Internet Protocol (“IP”) address corresponding to a valid current IP address, based on the first URI, and may advertise the IP address and/or a route based on the IP address. A communications link may be established between the user device and the external device based on the IP address and/or the route.

Abstract: Implementations described and claimed herein provide systems and methods for serving content over a network. In one implementation, a method of serving content is provided. The method includes maintaining a first address record associated with serving a resource and a second address record associated with serving the same resource. The first address record is further associated with a first protocol for a first device capable of serving the resource. Similarly, the second address record is associated with a second protocol, different from the first protocol, for a second device, distinct from the first device, capable of serving the resource. The method further includes providing, in response to at least one resolution request for the resource, the first address record and the second address record.

Abstract: Automatic testing/analysis of local loops of telecommunications networks includes obtaining bits-per-tone data for a local loop of a telecommunications network and generating a bit value string from the bits-per-tone data. The bit value string is then analyzed to determine whether it includes a bit pattern indicative of an impairment of the local loop. Further approaches for automatically testing local loops of telecommunications networks include obtaining attenuation data for multiple tones carried by the local loop and determining whether the attenuation data falls below thresholds for providing a service using the local loop.

Abstract: Novel tools and techniques are provided for implementing management of routing across multiple voice or data networks with separate routing masters. In various embodiments, in response to receiving a request to establish a call between a calling party in a first network and a called party in a second network, a computing system might receive a first set of network information from a first routing database(s) that is operated by a first service provider and a second set of network information from a second routing database(s) that is operated by a second service provider separate from the first service provider; might analyze the received first and second sets of network information to generate a unified routing model for optimizing routing of the call through the first and second networks; and might establish the call through a selected optimized route based on the generated unified routing model.

Abstract: A dynamic SRMS (DSRMS) in a MPLS network generates unique segment identifiers for nodes of the network lacking segment identifiers (SIDs). The DSRMS receives network information from other nodes of the network that may include, for example, Internal Gateway Protocol (IGP) routing information, advertised prefix values for the nodes, and label values used in MPLS routing. The DSRMS analyzes the information and identifies nodes of the network that are not associated with a SID. For each identified node, the DSRMS generates a unique SID and then announces the SID to other nodes within the network. Generating the unique SID may include executing a hashing function using the IP address of the identified node as an input.

Abstract: A method for testing network devices for networks with a large traffic load utilizes one or more traffic load amplifiers to amplify the traffic load. The load amplifiers connected to the device may receive packets of an initial traffic load, multiply or copy the received packet, alter the destination address information in the header of the copied packets to generate packets with different destination addresses, and transmit the altered packets back to the device for further routing. The altered or copied packets may then be routed via the device back to the load amplifier for further amplification. Through this amplification process, a small initial load of packets may be amplified over and over by the load amplifiers until a target traffic load is achieved at the device to test the device performance at a large traffic load.

Abstract: Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems.

Abstract: In an embodiment, a computer implemented method receives flow data for one or more flows that correspond to a device-circuit pair. The method calculates a time difference for each flow that corresponds to a device-circuit pair. Based on the calculated time differences and the received flow data, the method updates a probability distribution model associated with the device-circuit pair. Then, the method determines whether a time bucket is complete or open based on the updated probability distribution model.

Abstract: Implementations described and claimed herein provide systems and methods for correlating one or more service areas of a network with one or more geolocation coordinates to determine available services for customers to the network. A service polygon may be generated that define an area in which a particular service offered by a communications network is available. The boundaries of the service polygons may be adjusted based on information corresponding to physical features of the initial area. The service polygons may aid a communications network in providing a list of available services to potential customers or devices connected to the network by determining one or more geolocation coordinate values of a potential connection site and comparing the values to the service polygons. A network management system may determine the available services, current or in the future, to offer such services to a customer to the network.

Abstract: In an embodiment, a method monitors a plurality of data streams passing through a router in the connectivity service provider environment, and for each of the data streams, periodically samples packets at the router. The method further generates a stream signature based at least on the payload of the sampled packets. The method further includes, for each generated stream signature, attaching information to the stream signature. Such information may, for example, include time-stamp information for the stream signature, or an identification of the router. The method may further comprise storing the stream signatures corresponding to the data streams in a database. The stored stream signatures may be compared to determine matching stream signatures. Matching signatures may identify data streams that carry identical or similar content.

Abstract: Novel tools and techniques are provided for implementing web-based monitoring and detection of fraudulent or unauthorized use of voice calling service. In various embodiments, a computing system might receive, from a user device associated with an originating party, a request to initiate a call session with a destination party, the request comprising user information associated with the originating party and a destination number associated with the destination party; might query a database with session data (including user information) to access permission data and configuration data; and might configure fraud logic using received configuration data from the database. The computing system might analyze the session data and permission data using the configured fraud logic to determine whether the originating party is permitted to establish the requested call session with the destination party; if so, might initiate one or more first actions; and, if not, might initiate one or more second actions.

Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for determining an estimated capacity for providing data from a telecommunications network to a plurality of end users. In one implementation, the estimated capacity for delivering the data to the end users is per transmission path or per access network connected to the telecommunications network. This information may be aggregated into a traffic flow table that illustrates the traffic flow and available capacity to one or more end user networks. Through analysis of the traffic flow table, the system determines an estimated available capacity to provide the data to the end users. The traffic flow table thus provides a more accurate estimate of the capacity of the telecommunications network to provide the data to the end users over previous capacity estimates.

The method includes, at a server in the CDN, wherein the server is currently processing at least one other request in at least one other session: receiving a connection request from a client, the connection request being associated with a corresponding content request; determining whether handling the content request will cause the server to become overloaded; and, based on the determining in (B) and on information about the content request, conditionally (i) accepting the content request, and (ii) terminating or throttling at least one session on the server.

Abstract: Methods and systems for reducing energy consumption. A method may include aggregating, for a prior time period, prior usage data from a plurality of computing nodes. Based on the aggregated prior usage data from the plurality of computing nodes, a usage threshold for decreasing cooling system output for the plurality of computing nodes and a local-time threshold for decreasing the cooling system output for the plurality of computing nodes are determined. Current usage data for the plurality of computing nodes is then received. When the current usage data reaches the usage threshold and the local time is after the local-time threshold, output of the cooling systems of the plurality of computing nodes is decreased.
