Aug 10, 1999

Appl. No.:

09/372402

Inventors:

Mark Tsimelzon - Sunnyvale CA

Assignee:

Akamai Technologies, Inc. - Cambridge MA

International Classification:

G06F 1516

US Classification:

709228, 709224, 7155011

Abstract:

A method for notifying a user of changes to pre-selected portions of a web page includes dividing a web page into a plurality of blocks. User-selection information is added to each of the plurality of blocks. The user selects ones of the plurality of blocks by exercising a select user option from the user-selection information associated with each of the plurality of blocks. User-selectable notification-enabling information is added to each of the user selected ones of the plurality of blocks and for each selected block the user defines the notification condition. Each of the user selected ones of the plurality of blocks are monitored. Changes made to each of the user selected ones of the plurality of blocks based upon the notification condition are detected. The user is notified when the detection indicates that the user selected notification condition has occurred.

International Classification:

G06F 9/445

US Classification:

717177

Abstract:

An application deployment model for enterprise applications to enable such applications to be deployed to and executed from a globally distributed computing platform, such as an Internet content delivery network (CDN). According to the invention, application developers separate their Web application into two layers: a highly distributed edge layer and a centralized origin layer. In a representative embodiment, the edge layer supports a servlet container that executes a Web tier, typically the presentation layer of a given Java-based application. Where necessary, the edge layer communicates with code running on an origin server to respond to a given request. In an alternative embodiment, the edge layer supports a more fully-provisioned application server that executes both Web tier (e. g. , presentation) and Enterprise tier application (e. g. , business logic) components.

Appl. No.:

Inventors:

Mark Tsimelzon - Sunnyvale CA, US

Assignee:

Akamai Technologies, Inc. - Cambridge MA

International Classification:

G05F 15/173

US Classification:

709246

Abstract:

A method is provided for processing an application on an edge server, wherein the application comprises a set of defined presentation, code and data components, each of which are preferably URI-addressable objects. In response to a client request, the presentation, code and data components are processed according to a set of metadata to generate a response, and the response is delivered to the client. The presentation components are typically content such as HTML fragments, WML fragments, or some combination thereof. The code components are typically Java servlets or beans, XSLT style sheets, or some combination thereof. The data components are typically XML files, native database formatted files, and the like. Each of the presentation, code and data components may have a distinct management profile, cacheability profile, deployment profile, invalidation profile, and security profile. These profiles are settable via metadata or other similar means.

International Classification:

G06F 15/16

US Classification:

709228, 709227, 709249

Abstract:

Business applications running on a content delivery network (CDN) having a distributed application framework can create, access and modify state for each client. Over time, a single client may desire to access a given application on different CDN edge servers within the same region and even across different regions. Each time, the application may need to access the latest “state” of the client even if the state was last modified by an application on a different server. A difficulty arises when a process or a machine that last modified the state dies or is temporarily or permanently unavailable. The present invention provides techniques for migrating session state data across CDN servers in a manner transparent to the user. A distributed application thus can access a latest “state” of a client even if the state was last modified by an application instance executing on a different CDN server, including a nearby (in-region) or a remote (out-of-region) server.

US Classification:

707 3

Abstract:

A Continuous Query Processor processes queries on continuously updating data sources or data streams and includes a Publication Manager for accepting published structured elements of data from data stream Publishers, a Subscription Manager for giving structured elements of data to one or more data stream Subscribers, a Query Module Manager for processing queries represented by Query Modules, a Query Module Store for maintaining deployed Query Modules, a Query Primitive Manager performing processing for various primitives that comprise a Query Module, and a Schedule Manager for coordinating when a primitive within a Query Module gets processed in order to maintain that each continuous query is continuously updated immediately upon the arrival of structured element data affecting any part of a continuous query.
