Patent number: 10063442Abstract: 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.Type: GrantFiled: June 21, 2016Date of Patent: August 28, 2018Assignee: MARLOW TECHNOLOGIES, LLCInventors: Frederick Douglis, David H. Shur, Joseph M. Sommer, Jacobus E. Van Der Merwe

Patent number: 8943193Abstract: A service model, integrated system, and method for enabling a service provider to deliver an integrated web hosting and content distribution service offering, which affords assured operational performance service levels, regardless of whether the customer's web site is served by the service provider's hosting center, the service provider's content distribution network (CDN), by a third party web host, or by a third party CDN. A monitoring system of the primary service provider receives detailed capacity and health statistics from any CDN under the operational control of the primary service provider, receives aggregate capacity and health statistics from other CDNs not under the operational control of the primary service provider. A redirection system then decides to which web host, content distribution network, or combination thereof, user requests for content are directed in order that operational performance service levels are maintained.Type: GrantFiled: April 4, 2012Date of Patent: January 27, 2015Assignee: Marlow Technologies, LLC.Inventors: Frederick Douglis, David H.

Patent number: 8804913Abstract: A system for monitoring quality of calls in a network. A server receives information concerning calls which begin or end in a network and at the same time receives measurements of a quality parameter such as bandwidth. This measurement data is provided by a probe, so that the server is able to correlate calls which are placed through the network with the quality of service in the network at that time. When the quality falls below a desired level, the server notifies the customer or the network operator so that appropriate action may be taken.Type: GrantFiled: December 26, 2009Date of Patent: August 12, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Eric Cheung, Mark Foladare, Shelley Goldman, Kermit H. Purdy, David H. Shur

Patent number: 5570346Abstract: A system for analyzing and estimating average transit delay and high percentiles of delay in a packet network. The system utilizes detailed packet switch measurements that are normally stored in a network database for maintenance and engineering purposes. The system randomly selects source and destination points and samples the stored maintenance measurements for network circuit elements located between the randomly selected source and destination points. These sampled measurements are transmitted to the system processor via electronic mail and the system generates a single server queuing model to determine average and variance of delay for each component. A network-of-queues model is then constructed to determine the end-to-end average delay and end-to-end variance of delay. An Erlang probability distribution is then fit to these end-to-end values to provide statistics of packet transit delay in the packet network.Type: GrantFiled: December 8, 1994Date of Patent: October 29, 1996Assignee: Lucent Technologies Inc.Inventor: David H.

Patent number: 5386414Abstract: A method and apparatus that uses the number of in-service trunks in each trunk group connected to a communication switch as the number of indices that are contained in its respective trunk group distribution table. Each of the indices of each trunk group distribution table corresponds to a single trunk ID of a respective in-service trunk of the trunk group. The method provides for a uniform distribution of call assignments among the indices. Thus, with the uniform distribution of indices, the assignment of trunks to calls will also be uniformly distributed. With trunk traffic distributed among all the trunks of a trunk group, the overall efficiency of the trunk group will be very high.Type: GrantFiled: September 17, 1993Date of Patent: January 31, 1995Assignee: AT&T Corp.Inventors: Ching-Roung Chou, Paul A.
