Publication number: 20080037568Abstract: A method for translating data packets from one network protocol to another is disclosed. A set of translation templates is constructed. The translation templates are then loaded into a translation template cache. In response to a data packet from a first network arriving at a translation router, an appropriate translation template is selected from the set of translation templates within the translation template cache according to the translation context of the data packet. Next, a new header for transmission into a second network is constructed by reading header fields of the data packet from the first network along with the appropriate translation template in the translation template cache. The data payload of the data packet from the first network is subsequently removed from the header of the data packet and then appended to the constructed header of the second network. Finally, the newly constructed data packet is transmitted to the second network.Type: ApplicationFiled: August 17, 2007Publication date: February 14, 2008Inventors: Richard Anderson, Marc Faucher, Christos Georgiou, Francis Noel

Publication number: 20060235957Abstract: The invention provides a method, system, and program product for managing a connection. In particular, the invention manages connection information in memory based on an expected usage of the corresponding connection. Connection information can be stored in faster memory, such as cache memory, when the connection is expected to have numerous additional messages. Similarly, the connection information for a connection not expected to have many additional messages can be swapped out of the cache memory and stored in relatively slower memory. As a result, the connection information that is more frequently used is more likely to be available in a faster memory.Type: ApplicationFiled: April 21, 2006Publication date: October 19, 2006Inventors: Marc Faucher, Christos Georgiou, Ann Rincon
