Method And System For Providing On-Demand Content Delivery For An Origin Server

View page
US Patent:
7136922, Nov 14, 2006
Filed:
Oct 15, 2002
Appl. No.:
10/272368
Inventors:
Ravi Sundaram - Cambridge MA, US
Hariharan S. Rahul - Cambridge MA, US
Assignee:
Akamai Technologies, Inc. - Cambridge MA
International Classification:
G06F 15/173
US Classification:
709224, 709217, 709223, 709235, 709245
Abstract:
An infrastructure “insurance” mechanism enables a Web site to fail over to a content delivery network (CDN) upon a given occurrence at the site. Upon such occurrence, at least some portion of the site's content is served preferentially from the CDN so that end users that desire the content can still get it, even if the content is not then available from the origin site. In operation, content requests are serviced from the site in the usual manner, e. g. , by resolving DNS queries to the site's IP address, until detection of the given occurrence. Thereafter, DNS queries are managed by a CDN dynamic DNS-based request routing mechanism so that such queries are resolved to optimal CDN edge servers. After the event that caused the occurrence has passed, control of the site's DNS may be returned from the CDN back to the origin server's DNS mechanism.

Method And System For Protecting Web Sites From Public Internet Threats

US Patent:
7260639, Aug 21, 2007
Filed:
Jul 9, 2002
Appl. No.:
10/191309
Inventors:
Michael M. Afergan - Cambridge MA, US
Andrew B. Ellis - Medford MA, US
Ravi Sundaram - Cambridge MA, US
Hariharan S. Rahul - Cambridge MA, US
Assignee:
Akamai Technologies, Inc. - Cambridge MA
International Classification:
G06F 15/16
US Classification:
709229, 709214, 709218, 709219, 709224, 709228, 726 12, 726 22
Abstract:
The present invention addresses the known vulnerabilities of Web site infrastructure by making an origin server substantially inaccessible via Internet Protocol traffic. In particular, according to a preferred embodiment, the origin server is “shielded” from the publicly-routable IP address space. Preferably, only given machines (acting as clients) can access the origin server, and then only under restricted, secure circumstances. In a preferred embodiment, these clients are the servers located in a “parent” region of a content delivery network (CDN) tiered distribution hierarchy. The invention implements an origin server shield that protects a site against security breaches and the high cost of Web site downtime by ensuring that the only traffic sent to an enterprise's origin infrastructure preferably originates from CDN servers. The inventive “shielding” technique protects a site's Web servers (as well as backend infrastructure, such as application servers, databases, and mail servers) from unauthorized intrusion—improving site uptime and in the process, customer loyalty.

Global Load Balancing Across Mirrored Data Centers

US Patent:
7734815, Jun 8, 2010
Filed:
Sep 18, 2006
Appl. No.:
11/522579
Inventors:
F. Thomson Leighton - Newtonville MA, US
Daniel M. Lewin - Charlestown MA, US
Ravi Sundaram - Cambridge MA, US
Rizwan S. Dhanidina - Boston MA, US
Robert Kleinberg - Somerville MA, US
Matthew Levine - Somerville MA, US

Hariharan Shankar Rahul - Cambridge MA, US
Srikanth Thirumalai - Needham MA, US
Jay Gunvantrai Parikh - Redwood City CA, US
Yoav O. Yerushalmi - La Jolla CA, US
Assignee:
Akamai Technologies, Inc. - Cambridge MA
International Classification:
G06F 15/173
US Classification:
709241
Abstract:
The invention is an intelligent traffic redirection system that does global load balancing. It can be used in any situation where an end-user requires access to a replicated resource. The method directs end-users to the appropriate replica so that the route to the replica is good from a network standpoint and the replica is not overloaded. The technique preferably uses a Domain Name Service (DNS) to provide IP addresses for the appropriate replica. The most common use is to direct traffic to a mirrored web site.

Methods And Apparatus For Network Coding

US Patent:
8081641, Dec 20, 2011
Filed:
Sep 27, 2006
Appl. No.:
11/529561
Inventors:
Dina Katabi - Cambridge MA, US
Hariharan Rahul - Cambridge MA, US
Sachin Katti - Cambridge MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H04L 12/28
US Classification:
370400, 370392, 370338
Abstract:
One embodiment is directed to transmitting encoded data over a broadcast medium to improve network throughput. A sending node may identify a first packet to be transmitted to a first network node and a second packet to be transmitted to a second network node. The sending node may determine whether the first network node stores the second packet and whether the second network node stores the first packet. If the sending node determines that the first network node stores the second packet and the second network node stores the first packet, it may code together the first and second packets to generate an encoded packet and may transmit the encoded packet over the broadcast medium. Thus, the first packet may be transmitted to the first network node and the second packet may be transmitted to the second node in a single transmission.
