World-wide-web server with delayed resource-binding for resource-based load balancing on a distributed resource multi-node network

A multi-node server transmits world-wide-web pages to network-based browser clients. A load balancer receives all requests from clients because they use a virtual address for the entire site. The load balancer makes a connection with the client and waits for the URL from the client. The URL specifies the requested resource. The load balancer waits to perform load balancing until after the location of the requested resource is known. The connection and URL request are passed from the load balancer to a second node having the requested resource. The load balancer re-plays the initial connection packet sequence to the second node, but modifies the address to that for the second node. The network software is modified to generate the physical network address of the second node, but then changes the destination address back to the virtual address. The second node transmits the requested resource directly to the client, with the virtual address as its source. Since all requests are first received by the load balancer which determines the physical location of the requested resource, nodes may contain different resources. The entire contents of the web site is not mirrored onto all nodes. Network bottlenecks are avoided since the nodes transmit the large files back to the client directly, bypassing the load balancer. Client browsers can cache the virtual address, even though different nodes with different physical addresses service requests.

Method and system for directing a flow between a client and a server

A content-aware flow switch intercepts a client content request in an IP network, and transparently directs the content request to a best-fit server. The best-fit server is chosen based on the type of content requested, the quality of service requirements implied by the content request, the degree of load on available servers, network congestion information, and the proximity of the client to available servers. The flow switch detects client-server flows based on the arrival of TCP SYNs and/or HTTP GETs from the client. The flow switch implicitly deduces the quality of service requirements of a flow based on the content of the flow. The flow switch also provides the functionality of multiple physical web servers on a single web server in a way that is transparent to the client, through the use of virtual web hosts and flow pipes.

System and method for enabling users to interact in a virtual space

The present invention provides a highly scalable architecture for a three-dimensional graphical, multi-user, interactive virtual world system. In a preferred embodiment a plurality of users interact in the three-dimensional, computer-generated graphical space where each user executes a client process to view a virtual world from the perspective of that user. The virtual world shows avatars representing the other users who are neighbors of the user viewing the virtual word. In order that the view can be updated to reflect the motion of the remote user's avatars, motion information is transmitted to a central server process which provides positions updates to client processes for neighbors of the user at that client process. The client process also uses an environment database to determine which background objects to render as well as to limit the movement of the user's avatar.

A method to deliver services to mobile users

Most online services are not geared to support disconnected mode of operation of a mobile device. This invention describes a method to make online services available to mobile users in disconnected mode by exchanging structured electronic messages. Such as a system can be used to build a custom service by combining service offerings from different service providers, and transmit the same to a personal agent an intermediary who would then provide the customized service.

System and method for concentration and load-balancing of requests

The invention relates generally to distribute computing environments and specifically to a system and a method for reducing the number of Object Request Broker (ORB) connections in an Internet Inter-ORB Protocol (IIOP) environment. Prior solutions required a n x m number of connections to handle requests from clients (82,84,86,88) to remote servers (92,94,96,98). The solution described allows there to be only m connections (81,91) through an intelligent concentrator (90), which significantly reduces requirements and allows scalability. Prior solutions did not utilize multiple intelligent master concentrator processes (90) to handle concentrator failure or dynamic scalability.

Systems and methods for managing distributed database resources

A system and method are described for implementing a distributed database caching system (300) with the capability to support and accelerate read and update transactions to and from one or more central Database Management System (DBMS) servers (330) for multiple concurrent users. The system and method include a resource abstraction layer in a database client driver in communication with remote server units (RSUs) (302A-302D) having a cache database (318A-318D). RSUs respond to user requests using the cache database if possible. If the cache database does not have the needed data, the RSU sends the request to a database subscription manager (DSM) in communication with the DBMS server (307). The DSM (307) responds to the request and sends predicate data based on queries processed by the DBMS server (330) for use in updating the cache databases (318A-318D).

Preferably, the system includes a denial of service attack detection component coupled to the request processing component and the rate control component and operable to monitor request metrics from the request processing component and provide configuration information to the rate control component.

Method and system for secure content delivery

A method of and system for secure content delivery. The method is carried out by a content delivery network service provider (CDNSP), which operates a secure CDN. The secure CDN may be a dedicated network or a subset of a larger distributed network that is managed by the service provider. A Web site obtains secure content delivery, preferably as a managed service, by aliasing the site (or given domains) to the CDN. Edge servers are selectively authenticated into the secure CDN before they can be used to deliver secure content, and the CDN service provider serves SSL pages over a secure connection on the site's behalf, preferably using an SSL certificate provided by the site. A copy of the customer's SSL certificate resides on the secure edge servers to allow them to serve SSL content on the customer's behalf. A key agent running on the edge server, however, ensures that the copy of the certificate only resides in memory and not on disk. Further, a server that cannot be fully monitored by the CDN service provider removes the certificate from its memory and no longer serves the SSL traffic.

Method and apparatus for web farm traffic control

Method and apparatus for efficient reactive monitoring

A technique for managing network elements significantly reduces the amount of monitoring related traffic by using a combination of aperiodic polling and asynchronous event reporting. A global resource (e.g., a network of interconnected nodes or resources) is partitioned into a plurality of separate nodes, giving a fixed resource budget to each of the nodes. When any of the nodes exceeds its budget, based upon local monitoring at that node, the node triggers a report, typically sending a message to a central manager. In response, the central manager then and only then issues a global poll of all (or substantially all) of the nodes in the network. A rate based technique can also be used to monitor resource usage at the nodes, and send a message to a central monitoring location only when the rate at which the value of a local variable changes is too high.

Load balancing in data networks

Method and apparatus for maximizing distance of data mirrors

The invention is a method and apparatus for mirroring and relaying computer data to improve continuity of data by maximizing the distance between two copies of the data in synchronous mode, zero data loss environments. In one embodiment, the invention uses multiple remote mirror sites to increase the distance of one copy of mirrored data from another copy of mirrored data. In another embodiment, the invention uses relays in a wide-area cascade to increase the distance of a remote mirror site from a server sending write requests. This is done without affecting system performance by allowing the server to continue performance when an acknowledgment is received from the first relay, without waiting for an acknowledgment from the remote mirror site.
