Abstract: A local Point-of-Service (POS) server can receive requests from POS terminals on the local network that are unable to communicate with a central POS server due to, for example, a loss of network connectivity. The local POS server can generate transactions based on the requests, and store the transactions in a queue. The local POS can then transfer the queue to a recovery agent executing on the central POS server once connectivity has been restored. The central POS server can process a transaction by invoking an API of an order management system using a command and input parameters comprised within a transferred transaction.

Abstract: Techniques are disclosed that enable an application to prioritize its traffic in an application-specific manner, such that traffic which is most important to this application can be prioritized over traffic that is less important to this application, where this prioritization information is reflected in differential treatment of the traffic within the network. An application conveys relative priority information for its traffic to a Web proxy or edge server, and this device then consults stored policy information to determine how the traffic should be prioritized in the network. The Web proxy also ensures that usage of network resources is balanced among multiple applications. Cookies are used for transmitting priority information between the edge server and application in an efficient manner.
