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.

The CPIR-enabling Servlets can be used to build various types of consumer product information systems for operation on the WWW.

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.

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.

Systems and method for selecting points-of-presence (POPs) to be used by client systems when accessing network resources from the Internet are disclosed. An access monitoring system capable of monitoring client system usage compiles usage profiles for each of a plurality of client systems as POPs are used to access the Internet. The POPs may charge for Internet access according a flat periodic fee, hourly rates, per-port rates, or other arrangements. Periodically, the access monitoring system evaluates the usage profiles to determine whether the client systems could have obtained access to the Internet for lower access costs if different POPs had been used. If so, the access monitoring system identifies the appropriate, cost-effective POPs and generates one or more scripts instructing the client systems to use the appropriate POPs. To subsequently access the Internet, the client systems execute the scripts and establish communication with the appropriate POPs. The process of monitoring usage and reevaluating which POPs should be used continues as desired. POP selection can also be conducted to balance load between various POPs based on the usage patterns described by the usage profiles.

An approach is provided for causing an extension of secure emergency network resources via one or more trusted point of presence. The approach involves determining a networking context, wherein the networking context initiates a request to join an extension mesh network to a currently trusted network. The approach also involves determining a target network trust level associated with the networking context, the currently trusted network, or a combination thereof. The approach further involves selecting the extension mesh network based on the target network trust level. The approach also involves initiating a joining of the extension mesh network to the currently trusted network.

The present invention provides a method for computing traffic between a pair of Points of Presence in an IP network by summing link utilization values measured for each link connecting a pair of Points of Presence and dividing the sum by the number of link utilization values included in the sum. The resulting average link utilization is the average link utilization of any link in the aggregate and may be multiplied by the number of active links connecting a pair of Points of Presence to reflect the total amount of traffic between the two Points of Presence. Future link utilization may be forecast by modeling the observed traffic between a pair of Points of Presence using wavelet multiresolution analysis to create an approximation curve that captures the long-term trend of link utilization and at least one detail curve that captures the short term deviation of link utilization around the long-term trend. A time series model of the approximation curve may then be constructed and used for forecasting. In a similar fashion, deviation of link utilization may be forecast.
