Level 3 Communications | Date: 2017-02-15

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.

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.

Aspects of the present disclosure include an activation, consolidation, and transformation system (ACT) for a telecommunications network. A request is received to provision one or more devices in a network and includes a key and key value. The request is routed to a data source associated with the key or key value of the request. Data is queried from the data source and validated by the ACT. At least one template is identified from a plurality of digital templates based upon attributes of the data that is applied to the at least one template and the template transforms the data to an output. The output comprises instructions for configuring a device for a telecommunications service based on the request.

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 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.

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 providing failover and load clustering features to one or more proxy servers of a content delivery network (CDN). In one embodiment, one or more proxy servers may announce a virtual host internet protocol (IP) and, to provide a failover feature, two or more of the proxy servers may also announce a more generic virtual network IP address that includes a broader range of IP addresses associated with the virtual network IP address. In another embodiment, each of the proxy servers in communication with the router may announce a generic IP network address to the router. In response to receiving a request for content from an end user of the CDN, the router may select a proxy server and load balance the received requests among the proxy servers.


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

A content distribution mechanism that distributes content of a content provider at various sites across a network and selects the site that is nearest a content requestor using an anycast address that resides at each of the sites. The sites are configured as nodes (or clusters) and each node includes a content server and a DNS server. The DNS servers are so associated with the content servers at their respective nodes as to resolve the name of the content provider to the IP address of the content servers at the nodes. The DNS servers each are assigned the anycast address in addition to a unique address, and the anycast address is advertised to the network (in particular, the network routing infrastructure) using Border Gateway Protocol (BGP). Node selection occurs when the network routing infrastructure selects a shortest path to the anycast address during DNS name resolution.

Methods and systems are described for monitoring communications in a packet-switched network. More specifically, the system initiates a communication between a network endpoint associated with a call mediator and at least a second network endpoint; records, at the call mediator, information associated with the communication; and upon termination of the communication, communicates, from the call mediator to an enterprise gatekeeper, the information associated with the communication.

In an embodiment, a computer-implemented method provides a service on a network. The method includes the following steps: (a) requesting, on a router, executable instructions from a remote server, the executable instructions specifying how the router is to operate to provide a service requested for a user of the network; (b) receiving the instructions; (c) initializing, on the router, a thread to execute the received instructions; (d) determining that a configuration of the router has changed; and (e) when the configuration of the router is determined to have changed, executing, on the initialized thread, the instructions to apply the service in accordance with the change in the routers configuration.
