Abstract: The present invention is directed to a method and system to preserve interoperability among processes in a distributed system through transformation of in-memory representation of different versions of the same data. When an upgraded process receives data from an un-upgraded process, the old protocol for desterilizing the data is used to convert the data into in-memory representation of the old protocol format.

When the upgraded process sends data to the un-upgraded process, the in memory representation of the data in new protocol format is first transformed into the in-memory representation of the old protocol format. The old protocol for serializing data is then used to convert it into the old protocol format understood by the un-upgraded process.

Abstract: In the preferred embodiment, the invention provides a modified Shortest Path First routing algorithm for use in a heterogeneous network. The routing algorithm is modified to include predetermined heterogeneous characteristics of the network nodes and to take these characteristics into account when calculating the shortest paths. For example, information may be included in the algorithm which identifies heterogeneous network nodes as it calculates shortest paths. Once a node has been identified as heterogeneous, i.e., capable of supporting at least two protocol sets, this information is carried over into subsequent path entries created by the routing algorithm. The algorithm then uses the encapsulation capability identifier in the calculation of the shortest paths by including the cost of auto-tunneling between heterogeneous nodes to be taken into account when determining the short path.
