Abstract: A computer-implemented method for providing data communication between two or more host systems is provided. The method comprises designating a first network as a primary network by updating a routing table, monitoring network connections on the first network channel and a second network channel, transmitting data on the first network channel according to the routing table, detecting termination of network connection on the first network channel, determining to transmit data traffic on the first network channel, modifying the routing table, transmitting data traffic on the second network channel according to the routing table, detecting connection on the first network channel, and in response to the detection of data traffic on the first network channel, measuring a network attribute and comparing against a satisfactory threshold, and selecting the first network channel for data communication if the network attribute value satisfies the threshold.

Abstract: Methods and systems are provided for providing redundancy in data network communications. Data traffic on a first network channel used for the data communication between the two or more host systems can be monitored to obtain one or more attributes associated with the data traffic. Based on the data attributes, it may be determined whether one or more anomalies associated with the attributes exist. If so, the anomalies may be used to determine whether they are indicative of an imminent or current network event or condition. In response to a determination that the one or more anomalies are indicative of the event or condition, a second network channel may be selected for the data communication between the two or more host systems.

Abstract: A system and method for creating a sample pool for a web-based survey including at least one host machine for serving an HTML document, a survey manager machine connected to each of the host machines, and a least one executable tag embeddable in the HTML document, the executable tag being operable to communicate with a process running on the survey manager machine to create the sample pool when a user accesses the HTML document.
