| 20100115126 | AUTOMATED CONVERSION OF VERSIONED DATA COLLECTIONS - Various computing components (such as devices, operating environments, and processes) may communicate by exchanging instances of a data collection, such as a class or data structure. However, the definition of the data collection may evolve to specify different numbers, types, properties, and orderings of the items in the data collection, and it may be difficult to verify the structure and contents of an instance received from another component and possibly of a different version. This difficulty may be mitigated by exchanging versioning information about the instance (e.g., as part of the communications wire protocol) and by allocating the converting such that the sender may downconvert to earlier versions requested by a recipient, while the recipient may upconvert to later versions than a version provided by a sender. These techniques may promote the accuracy and consistency of information exchange among many components that operate on different versions of the data collection. | 05-06-2010 |

| 20130013805 | TRANSPARENT AUTO-DISCOVERY OF NETWORK DEVICES LOGICALLY LOCATED BETWEEN A CLIENT AND SERVER - Discovery of intermediate network devices is performed using a technique that piggybacks upon the existing standard TCP (Transport Control Protocol) “SACK” (Selective Acknowledgment) option in a SYN/ACK packet so that discovery information may be shared between pair-wise-deployed peer intermediate devices when a TCP/IP connection (Transport Control Protocol/Internet Protocol) is first established between network endpoints using a conventional three-way handshake. Use of the SACK option is combined with another technique which comprises modifying the original 16-bit value of the TCP receive window size to a special arbitrary value to mark a SYN packet as being generated by a first peer device. The marked SYN when received by the second peer device triggers that device's discovery information to be piggybacked in the SACK option of the SYN/ACK packet. The first device then piggybacks its discovery information in the SACK option of the ACK packet which completes the three-way handshake. | 01-10-2013 |
