Abstract: The present invention aims at avoiding fragmentation during transmission of a structured document (10). This is achieved by a method of progressive transmission for a structured document (10), the structured document (10) comprising sub-documents (12, 14, 16, . . . ) with related relevance weightings. In particular, a fragmentation measure is determined according to the transmission sequence in an automatic manner using a formal expression of fragmentation. After comparison the fragmentation measure with a predetermined threshold value the transmission sequence is modified to reduce fragmentation when the fragmentation measure exceeds the threshold value.

Abstract: A conversion system for converting a source disk image supporting a first hardware configuration into a target disk image supporting a second and different hardware configuration. The conversion system includes a first server that mounts the source disk image as a target disk drive, a repository that stores information and files useful for supporting the second hardware configuration, a rules library that facilitates conversion of hardware specific attributes in accordance with an external introspection process (EIP), and a conversion engine executed on the first server and interfaced with the repository and the rules library. The conversion engine performs the EIP by examining the source disk image on the target disk drive to determine modifications to convert to the target disk image.

Abstract: A computer system of a federation coupled to a network including a server having an internal address associated with a first subnet and a network abstraction and isolation layer rules-based federation and masquerading (NAIL RBFM) interface that interfaces the server with the network. The NAIL RBFM interface transforms the internal address between the first subnet and a second subnet for intra-federation communications. The NAIL RBFM interface performs transform and inverse transform operations to convert between internal and external addresses of intra-federation network traffic. The operations may be performed on source and destination addresses, and may be configured in any of several manners, such as modifying at least one bit of an address, replacing at least one octet of an IP address, substituting a prefix of an address, replacing an entire address, etc.
