Various embodiments of the present invention provide methods, in distributed data-storage systems that associate one or more timestamps with each data block in each data-storage-component, for deciding whether or not a data block has been written. In certain embodiments of the present invention, a sparse database of timestamps associated with data blocks is maintained, each timestamp having a field that contains one of an indication of a time or sequence and a sentinel value indicating that the timestamp is garbage collected. When a timestamp is not found associated with a data block in a timestamp database, the data block is associated with a garbage-collected-timestamp state. In various embodiments of the present invention, data structures are maintained that store status information indicating whether or not any of a number of data blocks in each of a number of data-block-allocation units have been written. During replication, migration, or reconfiguration of a current segment of data blocks to a new segment of data blocks in these various embodiments, a data block is determined to be written or to be unwritten by determining, from the data structures, whether or not a data block-allocation unit containing the data block is written or unwritten.

A method for transporting real-time data such as voice over a packet-based infrastructure, and a switch for use with that method, are disclosed. In this method, datagrams from multiple data streams are packaged in a single tunnel packet for transport across a network to an intermediate switching point (switch). To reduce bandwidth, each datagram in the tunnel packet (e.g., tunneled datagram) can be sent in a compressed-header format identified by a context identifier (CID) for its data stream. The switch saves context state for each tunnel and CID it is receiving packets for. The switch deaggregates received tunnel packets into tunneled datagrams and associates each datagram with its context state. Based on the destination indicated in its context state, each datagram it re-aggregated in an outgoing tunnel packet bound for a next switch or the destination endpoint itself.
