Method of and system for delivering consumer product related information to consumers over the Internet. The system and method involves creating an UPN-encoded Consumer Product Information (CPIR) enabling Applet for each consumer product registered within a manufacturer-managed UPN / URL database management system. Each CPIR-enabling Applet is encapsulated within an executable file and then stored in the UPN / URL database management system. Each CPIR-enabling Applet is searchable and downloadable by, for example, (1) retailers purchasing products from an electronic-commerce enabled product catalog, (2) advertisers desiring to link consumer product information to Web-based product advertisements, or (3) anyone having a legitimate purpose of disseminating such information within the stream of electronic commerce. After downloading and extraction from its encapsulating file, the CPIR-enabling Applet is embedded within an HTML-encoded document associated with, for example, an EC-enabled store, on-line auction site, product advertisement, Internet search engine or directory, and the like. Upon encountering such an Applet-encoded HTML document on the WWW, the consumer need only perform a single mouse-clicking operation to automatically execute the underlying CPIR-enabling Applet (on either the client or server side of the network), causing a UPN-directed search to be performed against the manufacturer-defined UPN / URL Database, and the results thereof displayed in an independent Java GUI, without disturbing the consumer's point of presence on the WWW. Preferably, the CPIR-enabling Applets are realized using Java(TM) technology, although it is understood that alternative technologies can be used to practice the system and methods of the present invention.

Presented is a system and a method for load balancing multiple globally-dispersed servers based on client-centric performance criteria. The infrastructure of the system includes load balancing domain name servers (DNS-LBs) deployed in close physical proximity to the Internet service providers' points of presence. The DNS-LBs are then able to monitor the performance of the servers from a location close to the clients, which allows the DNS-LBs to select a server that will yield the best performance from that location for the client. A second level of the infrastructure utilizes domain name servers (DNS-Bs) that are deployed on the Internet backbones and regional provides. The authoritative domain name servers (DNS-As) for the servers to be load balanced refer all name queries to these DNS-Bs. The DNS-Bs then refer the queries to one of the DNS-LBs based on a mapping of the DNS-ISP address to its physically proximate DNS-LB. The DNS-LB then returns the IP address of the server that will provide the best performance from that location.

A remotely programmable broadcast content recording system is programmed through a web page to record broadcast content such as television programs. Accordingly, a user can select content of interest and program the system from almost any location using a web browser. A host system hosts a web site through which the user can browse program listings and select content. In response to the selection of a program by the user, the host system creates programming data and transmits the programming data to the user's recording system. The recording system can be configured to receive transmissions from the host system. A client programming module configured to receive the transmissions can be used to program a conventional recording device. The recording system can be supplemented with a web server and an Internet connection to provide a point of presence on the World Wide Web through which the system can be directly programmed.

Round-trip time (RTT) for communication between an edge point of presence (POP) in a content delivery network (CDN) and a local domain name server (LDNS) is determined by resolution of a canonical name (CNAME) record. A first server in a first edge POP in a CDN receives a request to resolve a domain name from a LDNS and transmits a CNAME record including a timestamp indicating when the CNAME record was transmitted to the LDNS. The first server subsequently receives a request from the LDNS to resolve the CNAME record and determines a RTT time indicating the time needed for round-trip transmission between the LDNS and the first server based on the time when the request to resolve the CNAME request was received by the first server and the time indicated by the timestamp.

A remote access client is provided for enabling communication between a remote data terminal configured to access a public network, and an enterprise network by way of a VPN tunnel through the public network. The remote access client includes at least one application program interface (API) to receive a first verification of the operating state of a predetermined application of the remote data terminal to enable a connection agent for establishing a point of presence on the public network. Upon connection to the point of presence, the API exchanges data between the remote access client and the predetermined application of the remote data terminal. The remote access client receives a second periodic verification of the operating state of the predetermined application via the API for terminating the connection to the point of presence upon the absence of the second verification. The point of presence enables the VPN tunnel for transporting data from the remote data terminal to the enterprise network across the public network.

A database is populated with geographic locations for network devices by providing a node on a network and making a connection into a network service provider (NSP) point of presence (POP) to obtain a connection to the network via the NSP. A message is then transmitted to the node over the network connection obtained from the NSP. The message is received at the node and a source network identifier is extracted from the message. The source network identifier is then associated with a known geographic location for the POP in a database. The foregoing steps are then repeated for multiple different POPs. Also, a database is populated with geographic locations for network devices by providing a node on a network and making a connection into a network service provider (NSP) point of presence (POP) to obtain a connection to the network via the NSP. A message is then transmitted to the node over the network connection obtained from the NSP. The message is received at the node and a source network identifier is extracted from the message. The route over the network between the node and the POP is then probed to obtain network identifiers for routers along the route. The foregoing steps are then repeated for multiple different POPs.

An overlay protocol and system for allowing multicast routing in the Internet to be performed at the application level. The overlay protocol uses “native” Internet multicast and multicast routing protocols to route information, according to overlay routing tables. Overlay groups are mapped to native multicast groups to exploit native multicasting in regional or local forwarding domains. Use of the overlay protocol allows overlay distribution to be handled in a more intelligent and bandwidth-managed fashion. Overlay routers are placed at each of several local area networks, Internet service provider's point of presence, enterprise, or other cohesively-managed locations. The overlay computers are configured according to bandwidth and security policies, and perform application-level multicast distribution across the otherwise disjoint multicast networks by using the overlay routing. The result is an overlay multicast network that is effectively managed according to local network management policies. Application-level control can be applied to the transferred data at the overlay routers.

A server monitoring system monitors the performance of a web site or other Internet server system, as seen by users in multiple geographic access locations, without the need for special monitoring software or hardware within such locations. Automated agents that run at a central data center generate message traffic that is used to access and monitor the server system from the multiple remote locations. The message traffic associated with a particular remote access location is transmitted from the data center to the remote location across a dedicated link, such as an ATM link, and is routed onto the Internet at a corresponding Internet access point. The server response to each request message flows back to the data center across the same link as the corresponding request message. The remote access points thus serve as virtual points of presence for monitoring purposes. Server response times as seen from the remote access locations are determined by measuring the total response times as observed from the data center, and deducting from the total response times the round-trip latencies associated with the corresponding dedicated links. The response times and other performance data generated by the agents are aggregated within a database that is local to the agents. Multiple data centers may be interconnected such that each data center services a particular continent or other region using a respective set of virtual points of presence.

Some embodiments provide redundancy and failover for accelerating and improving the processing of commands across a distributed platform. A distributed platform administrative server distributes commands to different distributed platform points-of-presence (PoPs) for execution. The administrative server distributes the commands over a first set of transit provider paths that connect the server to each PoP. The administrative server selects the first set of paths based on different addressing associated with each of the paths. If any of the first paths is unavailable or underperforming, the administrative server selects a second path by changing a destination address and resends the command to the particular PoP over the second path. Some embodiments further modify PoP server operation so that the PoP servers can identify commands issued according to the different path addressing and distribute such commands to all other servers of the same PoP upon identifying the different path addressing.
