Messages from a network are processed so that each received message is received in one of a plurality of message formats, the content of each message is determined, and a network destination to which the message will be directed is selected, based on the determined message content. Specific embodiments can implement the migration of VM disk images without service interruption to the running workload. The second information handling system forwards the satisfied challenge without divulging the private key. In the area where the positive electrode material mixture layer and the negative electrode material mixture layer are opposed to each other, the ratio R:WpWn is 1. The analytical test piece exhibits high quality, and facilitates accurate testing with only a small amount of a sample.
