Appl. No.:

12/769270

Inventors:

Cheng Huang - Redmond WA, US
Nicholas Leonard Holt - Seattle WA, US
Albert G. Greenberg - Seattle WA, US
Jin Li - Bellevue WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 15/173
G06F 15/16

US Classification:

709224, 709239, 709219

Abstract:

A top level domain name system (DNS) server receives a DNS query from a local DNS resolver, the DNS query requesting a network address corresponding to a domain name. The top level DNS server reflects the local DNS resolver to a reflector DNS server. The reflector DNS server reflects the local DNS resolver to a collector DNS server, which in turn returns the network address to the local DNS resolver. The reflector DNS server and collector DNS server are both in the same data center, and one or more network performance measurements for communications between the local DNS resolver and the data center are determined based on the communications between the local DNS resolver and both the reflector DNS server and the collector DNS server.

US Classification:

709203

Abstract:

Techniques are provided for the caching of content prior to the content being requested. A request for desired content may be received from a client application at a caching server. The request may also indicate additional content related to the desired content that may be subsequently requested by the client application. The indicated additional content (and the desired content, if not already cached) is retrieved from an origin server. The desired content is transmitted to the client application at the user device, and the additional content is cached at the caching server. Subsequently, a second request may be received from the client application that includes a request for the additional content. The additional content, which is now cached at the caching server, is served to the client application by the caching server in response to the second request (rather than being retrieved from the origin server).

H04L 12/715

Abstract:

In various embodiments, methods and systems for implementing distributed traffic management are provided. A data request from a content server is accessed using a content serving agent. The data request is determined to be associated with a corresponding network link based on referencing an exterior protocol topology file. The exterior gateway protocol topology file includes a mapping of Internet Protocol (IP) prefixes to corresponding router-network-link identifiers indicating a router interface. A router-network-link identifier and one or more local control actions for the data request are identified using the control output file that includes a mapping between the router-network-link identifier and the one or more local control actions. Utilization data for the router-network-link identifier is accessed using the utilization data file. The utilization data is determined to be associated with executing one or more local control actions. The one or more local control actions associated with transmitting the data request are executed.
