Abstract: A secondary device receives an instruction message accompanied by a counted value and compares the received counted value with a counted value stored in an internal memory. Thus, it is determined whether the currently received instruction message is the same as a previously received instruction message and an execution of a process based on the previous instruction message was completed. When the received instruction message is not the same, the secondary device transmits a response message after executing a process according to the received instruction message. In contrast, when the instruction message is the same, the secondary device transmits a response message based on a process history in the internal memory without executing the process according to the received instruction message.

Abstract: Data is synchronized among multiple web servers, each of which is coupled to a common data server. Each web server retrieves a scheduled activation time from the data server.

At the scheduled activation time, each web server copies data from its staging cache to an active cache in the web server. If a new web server is added or an existing web server is initialized, then data is copied from an active cache in the data server to an active cache in the new or initialized web server. The multiple web servers may be arranged to form a web farm.

Abstract: The digital network modem has a built-in Dynamic Host Configuration Protocol (DHCP) mechanism for dynamically assigning network addresses to clients on the local network. To prevent confusion with a potentially existing DHCP server on the local network, an autosense mechanism is provided to detect the existence of a DHCP server and disable the internal, built-in DHCP mechanism. At power-on, the modem has no knowledge of clients on the local network, and the addresses in use are checked prior to operation. Addresses in use are placed in a list in a store of unknown addresses, and are not assigned to clients requesting DHCP addresses. When a DHCP client requests an address and has as its current address one of the addresses on the list, the current address is removed from the list. The list of unusable addresses is thus minimized and the same address will not be used for two clients.

Abstract: Systems and methods for performing automated load and usability testing via an application delivery appliance can include methods where a browser having a unique identifier is detected and a script is injected into the HTML response generated by the page displayed within the browser. The injected script renders the page and the links on the page, and then selects a link within the rendered page.

Abstract: A node (101, FIG. 1), within a networked computer system (100), is capable of supporting communications with other nodes relating to operating multiple application instances in a master-slave configuration. A node can be designated as a permanent master for an application instance, meaning that the node will enter the master state (218, FIG. 2) for the application instance whether or not another master exists on the network. A node also can be designated as a preferred slave. A preferred slave initializes (306, FIG. 3) its election timer that is below the election timers selected by other slaves, which causes the preferred slave to call an election before any other slave, and increases the likelihood that the preferred slave will become master if a failover occurs. In addition, a master can specifically resign (510, FIG. 5) to a preferred slave.

Abstract: A single-wire communication bus couples a transmitting device to a UART in a receiving device. Flow control circuitry in the UART fills a transmit memory buffer with remote data. The UART supplies a remote start bit onto the single-wire bus for each byte of remote data written into the transmit memory buffer. After detecting a remote start bit on the single-wire bus, the transmitting device supplies initial data bits and a stop bit, which together form an RS232 character. Data flow is controlled when the UART supplies a subsequent remote start bit only after data has been read out of the UART freeing up bytes in a receive memory buffer. After the transmitting device detects the subsequent remote start bit, the transmitting device supplies subsequent data bits onto the single-wire bus. In another embodiment, flow control circuitry functionality is performed by flow control code in the receiving device operating system.

Abstract: Pages are dynamically composed in order to increase the overall value of the page. In one approach, the overall value of the page is a function of the actual values of the page components that compose the page. These, in turn, are functions of the nominal value of the page components and of an effectiveness of the page components on the page. The actual values of the page components are expressed in a same unit of measure, thus facilitating direct comparison of their relative values.
