Abstract: A method is disclosed for application layer message-based network element management of server failures. According to one aspect, a network element such as a router intercepts session state information that is contained in a request from a client and locally stores the session state information. As a result, application servers to which the requests are directed do not need to store the session state information. If an application server fails, then the network element can use the session state information stored at the network element to continue the session with another application server, transparently to the client application that is involved in the session.

Abstract: A land pattern for 1 mm and 0.8 mm pitch arrays has been disclosed for placing two port devices. The land pattern includes a ball grid array (BGA) of BGA pads each connected to a respective through hole via, and a pair of rectangular conductive pads electrically connected to a an adjacent pair of through hole vias, wherein each rectangular pad extends out from its via towards the other via of the pair along a line connecting the centers of said adjacent pair vias. A solder mask is located on the rectangular pad side and has apertures over each rectangular conductive pad. The land pattern is particularly useful for locating two port devices directly underneath a BGA device while minimizing the distance from a BGA ball to the two port device lead.

Abstract: A method is disclosed for reducing the sizes of application layer messages in a network element such as a network switch or router. According to one aspect, the network element receives data packets and determines an original application layer message that is collectively contained in payload portions of the data packets. The network element compresses the original application layer message into a compressed message, and sends the compressed message toward an application that is hosted on a device other than the network element. According to another aspect, the network element receives data packets and determines a compressed message that is collectively contained in payload portions of the data packets. The network element decompresses the compressed message into an original application layer message, and sends the original application layer message toward an application that is hosted on a device other than the network element. Compressed messages consume less network bandwidth.

Abstract: A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a set of message classification rules that have been prepared beforehand by a system administrator or customer. The system analyzes the message classification rules to determine what part(s) of the message are necessary to classify a message according to the message classification rules. This allows the system to consider only the relevant parts of the message and ignore the rest of the message. The system extracts the portion of the message necessary for classifying the message and classifies the message using the values of the extracted information and the message classification rules. A unique sequence of operations is implied by the message classification and those operations must then be applied to the message.
