Patent
Level 3 Communications | Date: 2017-03-22

A quality of service management system includes a rules engine that receives information associated with a communication path having an assigned quality of service (QoS) to be provided for a customer communication device, and identifies one or more network elements assigned to provide the communication path. Each network element having a plurality of queues configured to provide varying QoS levels relative to one another. For each of the network elements, the rules engine determines at least one queue that is configured to provide the communication path at the assigned quality of service, and transmits queue information associated with the determined queue to its respective network element, the network element conveying the communication path through the determined queue.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for implementing a virtual service control point in a telecommunications network. In one embodiment, the system and methods involve implementing the functions of a service control point (SCP) device on one or more computing devices, such as application servers of the network, of the telecommunications network to create a virtual service control point device. In one embodiment, the virtual SCP may translate toll-free communications, such as 8xx based telephone communications, into a destination address associated with a customer of the network. In addition to resolving communications into a destination address or number, a virtual SCP instantiated in a network may provide one or more routing rules or features for such communications to a customer.

A method of generating a routing table containing information as to the weighted distance between clients that use a resolver and each rack gateway, taking into account how traffic to each client can egress from the CDN AS. The routing table is generated from matrix multiplication of two matrices. One matrix contains information as to the proportion of each clients use of each resolver in a first autonomous system. The second matrix contains information as to the distance between each client and each rack, with respect to an egress gateway, in a second autonomous system. The resulting routing table is used to identify a gateway from which to serve content to a client.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for implementing a high-quality Video over Internet Protocol (VoIP) network accessible through a public network, such as the Internet. More particularly, a user of a telecommunication network may access the VoIP through an Internet connection or other public network connection and is then connected to a virtual local loop for transmission across the VoIP. As such, the public network may act as an egress and/or ingress to the VoIP allowing users with public network connectivity access to the network. Thus, a virtual local loop providing the desired services and quality from the telecommunications network may be created for a user of the network, without the need of the user to directly connect into the VoIP.

Level 3 Communications | Date: 2017-02-08

A method for routing communication traffic in a network includes detecting that a link in a parallel link configuration has failed and, in response, adjusting one or more metrics associated with other links in the parallel link configuration to indicate that none of the links in the parallel configuration are available. A router connected to a direct link in a parallel link configuration including one or more other routers connected to one or more indirect links, respectively, includes a memory storing configuration parameters specifying a minimum number of links required to be operational in the parallel link configuration and an artificially high cost, and a link metric adjustment module operable to set a metric of the direct link to the artificially high cost until the minimum number of required links are operational after startup of the router or failure and reactivation of the direct link.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for extracting information associated with one networking transmission protocol, such as Internet Protocol version 6 (IPv6), based on information associated with a different networking transmission protocol, such as Internet Protocol version 6 (IPv4). More specifically, when resolving an IP address for a Uniform Resource Locator (URL) through which a content file may be obtained, the system may base the resolved URL on attributes of an IPv4 address extracted from an IPv6 address for a machine associated with the request. In one particular example, a geographic location of a requested computing device or machine may be determined or estimated based on an IPv4 address extracted from an IPv6 address associated with the request.


Patent
Level 3 Communications and Callahan | Date: 2017-02-22

Implementations described and claimed herein provide systems and methods for generating network intelligence based on network data. In one implementation, a network traffic dataset representative of network traffic across one or more ports of a primary network is obtained. The ports are associated with a secondary network in communication with the primary network. A content distribution network log associated with the secondary network is obtained. The content distribution log includes a history of content requests. A domain name system log associated with the secondary network is obtained. The domain name system log includes one or more Internet Protocol addresses. Network intelligence is generated based on the network traffic dataset, the content distribution network log, and the domain name system log. The network intelligence may be customer analytics, an aggregated data feed, and/or recommendations for inventory placement.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for managing the distribution of content and/or communications from a computer network to an end user of the network. In general, the system receives a request for content from the network and determines a server or content providing component within the network to provide the content to the user. In addition, the network may reduce the number of components and distance requests for the content are transmitted through the associated networks. The network may provide altered destination paths to one or more access networks through which the end user accesses the network. The altered destination paths may be used by the end users service provider or local network to select an access network for accessing the computer network to minimize the impact on the computer network for providing the content to the end user.


Patent
Level 3 Communications | Date: 2017-02-15

In an embodiment, a method exchanges routing data within a network including control and forwarding on separate devices. In the method, a first reachability information session is established between a forwarding device and a first control device and a second reachability information session is established between the forwarding device and a second control device. Also, a third reachability information session is established between the forwarding device and an external routing device. Finally, advertisements are exchanged between the first and second reachability information sessions and the third reachability information session such that the first and second control device appear to the external routing device to be a single device. System and computer program product embodiments are also disclosed.
