A defragmentation technique determines the extent to which data blocks of a file are fragmented on disks of a computer and, in response, efficiently relocates those blocks if such relocation improves the on-disk layout of the file. Each indirect block of the file is examined and the current layout of the range of pointers referencing the data blocks is determined. In addition, the number of operations needed to retrieve those data blocks from disks is calculated. A potential new layout is then estimated based on an average fullness of the file system. If the potential new layout improves the fragmentation of the current layout, then the data blocks for that range are relocated, if there is sufficient free space on disk. Otherwise, the blocks are not relocated and the current on-disk layout of the file is maintained.

One embodiment of the present invention provides a system for facilitating fragmentation of packets with hierarchically structured variable-length identifiers (HSVLIs). During operation, the system receives an interest packet with an HSVLI corresponding to a piece of content. The system then identifies a minimum path maximum transmission unit (MTU) value carried in the packet. In response to the piece of content not being stored locally, the system then determines an egress port for the packet based on the HSVLI. The system further determines an MTU associated with the egress port. Subsequently, in response to the MTU associated with the egress port being less than the minimum path MTU value carried in the packet, the system updates the minimum path MTU value in the packet to the MTU value associated with the egress port.
