  • Patent number: 10594581
    Abstract: A system includes first and second cache servers, a domain name server, and a route controller. The cache servers respond to an anycast address. The first and second cache servers respond to first and second unicast addresses respectively. The router controller determines if the first cache server is non-overloaded, overloaded, or offline. The route controller instructs the domain name server to provide the second unicast address when the status is overloaded or offline, and modifies routing of the anycast address to direct a content request sent to the anycast address to the second cache server when the status is offline. The domain name server receives a request from a requestor, and provides an anycast address to the requestor when the status of the first cache server is non-overloaded, and provides the second unicast address to the requestor when the status of the first cache server is offline or overloaded.

  • Patent number: 10164958
    Abstract: Authentication of devices to receive services provided by service providers over communications networks such as open access networks, wherein the provider of the network need not have access to secret information shared between the devices and the service providers. A request is received from a device to receive services from a service provider and is forwarded to the service provider. A challenge and an expected response is received from the service provider and the challenge is forwarded to the device. A response to the challenge is received from the device the device is authenticated to receive services from the service provider if the response received from the device matches the expected response provided by the service provider.

  • Publication number: 20180302236
    Abstract: A method includes dividing, at a cable modem termination system, a transmit stream into multiple data streams. The multiple data streams include a first data stream and a second data stream. Each of the multiple data streams has a lower bit rate than a bit rate of the transmit stream. The method includes transmitting, via the cable modem termination system, the first data stream over at least a first channel of a group of channels. The method also includes transmitting, via the cable modem termination system, the second data stream over at least a second channel of the group of channels. The group of channels supports traffic to a plurality of destinations. The first channel and the second channel are frequency-division multiplexed channels.

  • Patent number: 10063442
    Abstract: A domain name server request is received from a local domain name server. Operational performance parameters of a web host and a first content distribution network are received. Aggregate operational performance parameters of a second content distribution network are received. A first record is sent to the local domain name server that indicates the domain name server request is to be handled by the web host on a condition that a performance value is below a predetermined operational performance level threshold. A second record is sent to the local domain name server that indicates the domain name server request is to be handled by the first or the second content distribution network on a condition that the performance value is equal to or above the predetermined operational performance level threshold.

    Abstract: A system including first and second servers, a domain server, and a route controller is disclosed. The first and second servers are configured to respond to an anycast address and to first and second unicast addresses respectively. The route controller is configured to determine whether the first cache server is non-overloaded, overloaded, or offline, and may instruct the domain name server to provide to provide the second unicast address when the status is overloaded or offline. Routing of the anycast address may be modified so as to direct a content request sent to the anycast address to the second cache server when the status is offline. The domain name server may receive a request for a cache server address and provide the anycast address to the requestor when the status is non-overloaded, and provide the second unicast address when the status is offline or overloaded.
