Abstract: The invention is suitable for any kind of distributed networks having different data rates on different connections and a centralized computer system wherein the data to distribute is created. The central system comprises one or more supersets of data that is to be distributed to client computers by extracting subsets of data from the superset/s of data. Thereafter the subsets of data are distributed to selected groups of clients based on information about the network architecture. In this way an efficient way of distributing data is executed and no duplicated data is distributed. Preferably the subsets are distributed to clients based on a counter performance or a data rate of a client's connection to the central computer system.

Abstract: A method for financial transactions within a Central Securities Depository comprises a clearing process and a settlement process. The clearing process preparing the transactions for the settlement process selects a settlement rule to be followed in the clearing process. The rule defines how the transaction is to be settled and a settlement obligation group. The group includes a number of settlement instructions that must be settled at the same time. The clearing process also “locks in” the assets with which the transactions are concerned thereby reserving the assets for a specific settlement instruction. The settlement process includes selecting transfer instructions for all settlement obligations belonging to the settlement obligation group. The transfer instructions are irrevocable instructions to transfer the assets between participants in the CSD.
