Abstract: In accordance with exemplary embodiments, a method for monitoring a content delivery network includes obtaining data from devices within the network, organizing the data into hierarchically accessible tiers, and displaying at least part of the data at one of the hierarchal tiers, wherein the hierarchical tiers include a) a site tier including a map comprising ones of the devices that are potential content sources in the network, b) a service tier including a map comprising content-based relationships between the devices, and c) an operations tier including a map comprising characteristics of the devices and characteristics of relationships between the devices and content in the network.

Abstract: A system wherein work orders are used to accomplish polling of devices on a network. Work orders are created and passed to a scheduler which places the work order into one of a plurality of queues, based on the priority of the work order. As work orders are pulled from each of the queues, each work order is sent to a thread pool matching the priority, where the work order is executed. Within each work order is a run process that performs the actual polling of the node.

Abstract: In accordance with an exemplary embodiment, a method for displaying relationships between content devices in a content delivery network, where the content devices include a management computer and a plurality of caches, includes querying one of the content devices, receiving a response from the queried content device indicating a content distribution path among the content devices, and based on the received response, displaying a map showing the indicated content distribution path(s) among the content devices.

Abstract: In accordance with an exemplary embodiment, a method for monitoring streaming media flow in a computer network includes recording at least one address in an information packet, each at least one address corresponding to a location in the network where the information packet has been, and displaying a map showing a communication path in the network, the communication path being defined by the at least one address.

Abstract: A method and system is disclosed for automated event polling in a network. A server receives a HTTP request for data from a database on the server. A client generates the HTTP request for the data. The server responds to the request by reformatting the data into an XML format. The server then transmits the data in XML format to the client. The client receives the data transmitted from the server in XML format and converts the data in XML format to a format used by the client software.

Abstract: An application manager for managing applications in an embedded device is presented. The application manager allows remote control of loading, starting, stopping, unloading, application state querying of applications on an embedded device. Applications are cached in an application cache resident within the embedded device even after application termination to allow for higher efficiency when applications must be unloaded to handle low- or out-of memory conditions.
