  • Publication number: 20150230149
    Abstract: A differentiated routing system is provided for routing a communication service according to an access point of a subscriber terminal to a first network domain. The system includes a computing system executing a core routing engine (CRE) that receives a request for a communication service from the subscriber terminal. When the communication service is to be routed to a second network domain, the CRE identifies an access point at which the subscriber terminal accesses the first network domain, includes a tag in the request according to the identified access point. The tag includes information to be used by the second network domain for routing the communication service. The CRE then transmits the request to the second network domain.

  • Publication number: 20150215334
    Abstract: Implementations described and claimed herein provide systems and methods for generating threat intelligence based on network security data. In one implementation, a network traffic dataset representative of network traffic for an Internet Protocol address across one or more ports of a primary network is obtained. A content distribution network log associated with a content distribution network is obtained. The content distribution network log includes a history of content requests by the Internet Protocol address. The network traffic dataset is correlated with the content distribution network log based on the Internet Protocol address to obtain network security data. One or more threat attributes representative of malicious activity are identified from the network security data. The one or more threat attributes are weighted. Network threat intelligence is generated based on the weighted threat attributes using a processing cluster.

  • Patent number: 9021112
    Abstract: 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.

  • Patent number: 9013538
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for collaboration conferencing with multiple participants over a communications network, and more specifically for a conferencing routing service for managing and routing collaboration participants. In one embodiment, the conferencing system may utilize Session Initiation Protocol (SIP) to conduct the routing of the collaboration conferences within the telecommunications network. The SIP-based routing provides for the exchanging of information from one device of the conferencing system to another that is not available in non-IP based conferencing systems. Thus, through the use of IP-based telecommunication devices, the network provides beneficial features for collaboration conferencing.
