This invention relates to methods for controlling and monitoring access to network servers. In particular, the process described in the invention includes client-server sessions over the Internet. In this environment, when the user attempts to access an access-controlled file, the server subjects the request to a secondary server which determines whether the client has an authorization or valid account. Upon such verification, the user is provided with a session identification which allows the user to access to the requested file as well as any other files within the present protection domain.

Internet server access control and monitoring systems

Tracking a target across a region is disclosed. A graphical user interface is provided that displays, in a first region, video from a field of view of a main video device, and, in a plurality of second regions, video from a field of view of each of a plurality of perimeter video devices (PVDs). The field of view of each PVD is proximate to the main video device's field of view. A selection of one of the plurality of PVDs is received. In response, video from a field of view of the selected PVD is displayed in the first region, and a plurality of candidate PVDs is identified. Each candidate PVD has a field of view proximate to the field of view of the selected PVD. The plurality of second regions is then repopulated with video from a field of view of each of the plurality of identified candidate PVDs.

A security installation positions a peering ability with a peer installation by establishing a peering agreement to define the conditions constituting a situation for which peering applies, and identifies the resources and assets which will be shared, as well as the duration of the peering, typically until the resolution of the exigent situation or circumstances that prompted the peering. Peering selectively couples security installations for monitoring a particular upon determining that a situation responsive to mediation has occurred within an area monitored by the security installation for monitoring an area. The security installation initiates a peering invitation to a peer installation, in which the peer installation is configured to share resources with the security installation for mitigating the cause of the situation. The resulting peered access provides communication between the peer installation and the security installation, the access being temporary and conditional on the exigency of the determined situation.

Link traversals leading from an advertisement on the Web to a product page are determined. The determined link traversals are used as a basis for charging for advertising, for example, by counting the number of link traversals from the advertising page to a product page, or by counting the number of sales resulting from such traversals. The effectiveness of advertising on the Web is evaluated by measuring the number of sales or transactions resulting from link traversals from the advertisement to the page.

Service requests from a client to a server system through a network are processed. A session identifier is appended to requests for information. The server responds to the requests from the client by returning the requested information to the client. Requests to particular information are counted, exclusive of repeated requests from a common client.

Effecting the transmission of video data across a network of resources that includes incompatible resources is disclosed. Information indicating a source device and a destination device is received. The source device originates the video data and the destination device is to receive the video data. A plurality of paths between the source device and the destination device is identified. Each path is defined by a set of resources, the set of resources including resources needed to transmit the video data across any incompatible resources in the path. From the plurality of paths, a best path for transmission of the video data is determined based on the set of resources for that path, a distance between the source device and the destination device along that path, and a quality of the video data maintained by that path. The transmission of the video data is then effected across the determined best path.

Optimal routing of audio, video, and control data through heterogeneous networks

Intelligently crafting a dynamic video tour using a plurality of video devices selected in real time is provided. A list of attributes is received, the list of attributes describing at least one characteristic of a video device. A list of factors is continuously received, the list of factors describing one or more events, an event occurring at a point in time. A subset of the plurality of video devices is selected, based upon the received list of attributes and the received list of factors. The subset changes over time due to one or more changes in the list of factors. Video is displayed from the selected subset of the plurality of video devices as a tour, the displayed video changing over time as the selected subset changes over time.

Intelligent video tours

A method, system and apparatus are provided for dynamically pre-positioning content from servers located in a network, which may be a content distribution network. The content is pre-positioned on a proxy server, and the pre-positioning is triggered by at least one of the scheduling of an event and the presence of a user. Users commuting between different locations of a company can quickly and easily access the pre-positioned content. This content may be prioritized and pre-positioned, based on a user requiring a specific content at a particular time.

An apparatus and method for defining content distribution paths in a content distribution network integrate unicast and multicast connections. Content engines in the content distributed network are organized into channels with a master content engine maintaining specific content. The content distribution network is further organized into a distribution hierarchy based on network topology and channel definitions, first by establishing unicast paths through the content distributed network and then by integrating multicast paths into the unicast hierarchy. The further organization of the content distribution network establishes distribution trees from the channel masters to the network edges.

Conventional replication status reporting techniques in a Content Delivery Network (CDN) tend to produce large, unwieldy reports which are difficult to transmit, consume large amounts of bandwidth, and require a large share of CPU resources to process. A replication status reporter which identifies an ordered list of events corresponding to content items (files) for replication (pre-positioning) in a content delivery network, and determines a point of progression along a sequence represented by the ordered list of files, allows a management server to avoid computationally expensive endeavors which itemize and transmit lists of every replicated file in the CDN. The servers in a CDN channel receive files as a series of ordered events. Origin servers deliver the files generally according the event. A replication status report indicates the progression in the list, rather than enumerating the entire list, avoids cumbersome and unnecessary processing and delays in reporting replication status.

Content delivery network (CDN) replication status reporter

A content delivery network has a content switch that intercepts content requests transmitted toward the origin server. The content switch distinguishes the content request as originating either external to the content delivery network or from within the content delivery network. The content switch forwards external requests to a content router, within the content delivery network and forwards internal requests to the origin server. Devices external to the content delivery network do not access the content carried by the origin server directly and, therefore, the content delivery network does not require the origin server alter its content when storing the content on a content server within the content delivery network. Use of the content switch, therefore, minimizes or eliminates the time, effort, and expense of rewriting content cached from the origin server to the content server within the content delivery network.
