  • Patent number: 10812386
    Abstract: A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network. As such, when the normal traffic peaks or there are link failures or equipment failures, the normal traffic is preferentially transmitted over the bulk-transfer traffic and thus the bulk-transfer traffic dynamically adapts to changes in the available bandwidth of the network. Further, to reduce the impact of dropped packets for the bulk-transfer traffic, the packets of the bulk-transfer traffic are encoded at or near the source component using a loss-resistant transport protocol so that the dropped packets can be reproduced at a downstream link.

  • Patent number: 10805981
    Abstract: A method, computer-readable storage device and apparatus for closing a transmission control protocol connection in a wireless network are disclosed. For example, the method sends a first transmission control protocol option requesting a use of a silent transmission control protocol closure for the transmission control protocol connection, receives a confirmation from a recipient device that silent transmission control protocol closure is to be used for the transmission control protocol connection, sends a second transmission control protocol option that indicates a connection timeout period for the sender device, receives a connection timeout period for the recipient device, tracks the connection timeout period for the sender device and the connection timeout period for the recipient device, and closes the transmission control protocol connection when one of the connection timeout period for the sender device or the connection timeout period for the recipient device has expired.

  • 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.
