  • Patent number: 9391847
    Abstract: Aspects of the present disclosure involve provisioning customers of an aggregator, such as a reseller, of a content delivery network (CDN). In one aspect, content requests to the CDN are processed in accordance with the virtual IP (VIP) address at which the request was received, according to a property template bound to the VIP where the template is selected by the customer and only involves discrete parameters for the reseller. In another aspect, cache fills of the network are processed without direct knowledge of the customer origin through a combination of some request attribute, e.g., alias host of the customer, and an attribute of the reseller to make a DNS request to a name server outside the CDN. Another aspect involves receiving a property template selection, an origin and an alias from a customer of the reseller, and providing appropriate DNS entries to validate the customer and provide origin information to the CDN.

  • Patent number: 9380362
    Abstract: A communication network including a master switch and one or more local switches is provided with a loop-back test device for in line loop-back testing. The local switches convey communication traffic between one another using one or more channels of a transmission medium and configuration information using an out-of-band channel of the transmission medium that is separate from the channels used to convey the communication traffic. The master switch includes an application that generates configuration information including loop-back connection information for configuring the out-of-band channel using at least one loop-back test device, transmits the generated configuration information to the loop-back test device using the out-of-band channel of the transmission medium, and conducts loop-back testing using the out-of-band channel.

  • Patent number: 9378481
    Abstract: Implementations described and claimed herein provide a system and method for inventory management of data center equipment contained in server racks. In one implementation, the system and method include generating an identifying code that includes location information, hardware specific information, and equipment history of the equipment to be managed. The ID code is applied to the equipment or a portion thereof. A code scanner or reader is positioned within scanning range of the ID code when the equipment is positioned in the server rack. The code reader scans for ID codes and communicates the information associated with the codes to a communication device, which communicates the codes to a user or network device in a network environment. The information may then be analyzed, sorted, and displayed in a graphical user interface such that a user may evaluate, locate, and track the equipment.

  • Publication number: 20160182561
    Abstract: A route monitoring system disclosed herein includes a computing system executing a route monitoring service coupled to a communication network. The route monitoring service receives a route redirection message from one or more network elements in a communication network, and compares the route update information against one or more normalcy rules associated with potential malicious route redirecting mechanisms. The route redirection message includes route update information defining a change to a route through the communication network. When the comparison of the route update information to the one or more normalcy rules identifies a malicious route redirection attack, the service generates one or more remedial actions to mitigate the redirection attack.

  • Patent number: 9344361
    Abstract: A network includes a plurality of endpoint routers and intermediate routers. When a new data stream is detected at any endpoint router, the first packet is sent to a virtual routing server with knowledge of the entire network topology. Based on the topology, current usage, and historical usage, the virtual routing server determined a path for the data stream and begins to update the routing tables of the intermediate routers to reflect the determined path. Until the update is complete, all packets in the data stream are routed first to the virtual routing server and then to their destination. Once the update is complete, packets in the data stream are routed directly along the determined path.

  • Publication number: 20160119279
    Abstract: Aspects of the present disclosure involve a CDN utilizing a Direct Server Return (DSR) request command to create a tunnel from one content server to another content server of the CDN. Through the DSR tunnel, a request for content may be served from a content server that is more advantageous for the CDN for any number of reasons, such as from a content server that is logically closer to the content server. In determining when a DSR tunnel is created to provide the content, the CDN may access a database storing various information concerning the CDN, such as the location of egress gateways of the CDN in relation to one or more content servers, connecting network location information, the capabilities of one or more content servers, and/or load information of available content servers.
