Patent number: 9979588Abstract: A technology is described for prioritizing DNS name resolutions requests received from DNS resolvers. An example method may include receiving a DNS name resolution request addressed to a DNS name server from a DNS resolver. The DNS resolver associated with the DNS name resolution request may be identified as a known DNS resolver or an unknown DNS resolver, where a known DNS resolver may have DNS resolver characteristics that correspond to a valid DNS resolver. The DNS name resolution request may be prioritized according to the identity of the DNS resolver as a known DNS resolver or an unknown DNS resolver. The DNS name resolution request may then be provided to the DNS name server according to the priority assigned to the DNS name resolution request.Type: GrantFiled: February 16, 2015Date of Patent: May 22, 2018Assignee: Amazon Technologies, Inc.Inventors: Bryan Mark Benson, David Dongyi Lu, Michael F.

Patent number: 9934273Abstract: An iteratively updated metadata collection is used for making packet rewriting decisions at a flow management system. In a particular iteration at a particular rewriting decisions node of the system, metadata representing older local decisions is discarded, and metadata representing notifications of older rewriting decisions which were received at a different tier is also discarded. Representations of more recent local decisions and more recent notifications received at the different tier are added to the metadata collection during the particular iteration. New rewriting decisions are made using aggregations of the objects in the metadata collection.Type: GrantFiled: June 10, 2015Date of Patent: April 3, 2018Assignee: Amazon Technologies, Inc.Inventor: Colm MacCarthaigh

Publication number: 20170163759Abstract: Techniques are described for managing preloading of data for client computing systems. A client computing system may provide one or more persistent data storage caches on local storage, such as to support a particular software program executing on the client computing system (e.g., a Web browser program, with the persistent data storage cache designed to store browser cookies and other data for later access by the Web browser program). Additional data may be stored in such a persistent data storage cache by preloading those data groups before they are requested by the client computing system (e.g., based on interactions of a user of the client computing system with an executing program on the client computing system). Particular data groups to preload may be selected in various manners, including to provide a specified type of minimum functionality to a client computing system based on the preloaded data groups.Type: ApplicationFiled: February 21, 2017Publication date: June 8, 2017Inventors: Prashanth A.

Publication number: 20160373414Abstract: Cryptographically protected communications sessions are established using a distributed process. A server proxies handshake messages to another computer system that negotiates a cryptographically protected communications session with the client. When the client and other computer system complete negotiation of the session, the other computer system provides a set of session keys to the server. The server then uses the session keys to communicate with the client over the cryptographically protected communications session.Type: ApplicationFiled: June 16, 2015Publication date: December 22, 2016Inventor: Colm MacCarthaigh
