A network-based video encoding and decoding system encodes and decodes remotely displayed user application data on a centralized desktop computer. Remotely displayed user application data are screen captures of a browsing application run by the centralized desktop computer on user's behalf. The encoding system optimizes its encoding performance using back channel information which includes real time network capacity information and decoder feedback. The encoding system consults a back channel information manager to dynamically adjust encoding parameters. Based on the real time network capacity information received, the encoding system adjusts its capturing sampling rate. Based on encoding errors identified by the decoding system, the encoding system selectively re-send previously encoded frames/blocks, or send intra frames on demand to allow the decoding system to correct encoding errors. In response to encoding customization requests from the decoding system, the encoding system adjusts its encoding parameters to meet such requests.

The present invention comprises a multi-tier system. Major goals of the system are to 1) clearly visualize BGP dynamics and alert/report important deviation of BGP dynamics to avoid overwhelming the operators with too much information and 2) analyze the root cause of the problems by using a multi-tier approach, with a light-computational analysis and high-level classification for a real-time problem identification followed by a more rigorous off-line analysis for a further and more detailed trouble shooting. An example embodiment is provided that comprises four modules. The first module comprises a distributed family of collectors in charge of collecting real-time network information. The second module filters out non-relevant prefixes and extracts and profiles key features of the network information. The third module monitors BGP activity from both an Internet-AS and single-AS perspectives by displaying the data in real time and highlighting major shifts or divergence from historical baselines with comprehensive layouts. The forth module is run off-line to focus on a few relevant events that are selected through the first three modules. This is usually a time-consuming phase of the process due to the different temporal and/or spatial correlation that must be run across several sets of data. During this phase, the system can spend more time to better identify the real cause of the problem.

The customer presses the Connect button (2240) on the customer terminal (1230). By this, a connection request to an operator terminal is notified to an operator terminal (1210) via the push sharing server (2100). On receiving this notification, the operator terminal (1210) changes the Respond button (2310) to the Incoming button. When the operator presses the Respond button (2310) on the operator web page (2300), the push sharing server (2100) transmits a difference notification command to the operator terminal (1210), and the operator terminal displays the same web page as the web page on the customer terminals (1230).

Near real time Internet access of prepaid call history and replenishment data is provided via an Internet browser separate from the prepaid device to a user (e.g., the subscriber), allowing a subscriber to access call history and/or replenishment information nearly in real time (e.g., within a minute of the expense/credit) without requiring assistance from a customer service representative. A web based prepaid report page retrieves call history and/or replenishment information from the subscriber's service provider, and displays the same through a web browser for review by the subscriber. The requested call history and/or replenishment information may be bounded by date, date and time, or even within specific time range(s) within each day in a given range of days. The web based prepaid report page may also link the user to a replenishment application for the subscriber, to assist the subscriber in replenishing their account after having reviewed their call history and prepaid account status in near real time. The call history and account balance information is preferably updated in near real time after the completion of a call, which is then accessed by the web based prepaid report page. Substantially immediately after a prepaid call is ended, the web based prepaid reporting application formulates a Call Detail Record (CDR) and sends it over a TCP/IP link to the web based prepaid reporting application, which stores the CDR in a local database. Then, a user may access this CDR/RR information in near real time, after appropriate log-in with, e.g., a user ID of the subscriber (e.g., MIN number based), and perhaps a password. Once the requested information is entered, the web based prepaid reporting application queries its local database, formats an appropriate response to the user's request, and presents the call history and/or replenishment information to the web browser of the user.

The need to monitor real time network services has prompted service providers to use new measurement technologies, such as service-specific probes. A service-specific probe is an active probe that closely mimics the service traffic so that it receives the same treatment from the network as the actual service traffic. Service-specific probes are end-to-end and their deployment depends on solutions that address questions such as minimizing probe traffic, while still obtaining maximum coverage of all the links in the network. A polynomial-time probe-path computation algorithm is provided as well as a 2-approximate solution for merging probe paths when the number of probes exceeds a required bound k. The algorithms are evaluated using ISP topologies generated via Rocketfuel. For most topologies, it is possible to cover more than about 98% of the edges using just about 5% of the nodes as terminals.
