Abstract: A method includes storing a partition of a distributed document-oriented database in a computer. It is determined whether an assignment policy is unsatisfied, where the assignment policy specifies locations for documents within the distributed document-oriented database. A request for a transfer transaction to move a document from the computer is initiated when the assignment policy is unsatisfied. There is a wait for an indication of a transfer transaction commit or a transfer transaction abort. The transfer transaction is completed in the event of a transfer transaction commit, such that the document is moved from the computer. The transfer transaction is aborted in the event of a transfer transaction abort, such that the document remains at the computer.

Abstract: The present invention is directed to using measurement packets to compute network performance. Embodiments that send, receive and both send and receive measurement packets are described. Some embodiments are described that compute statistics based at least partly on measurement traffic. Some embodiments are described that communicate computed statistics within measurement traffic. Some embodiments are described that rank and select paths based at least partly on computed statistics.

Abstract: Methods and apparatuses for communicating data within measurement traffic are described. Embodiments that send, receive and both send and receive are described. Some embodiments are described that compute statistics based at least partly on measurement traffic. Some embodiments are described that communicate computed statistics within measurement traffic. Some embodiments are described that rank and select paths based at least in part on computed statistics.
