Abstract: A method is disclosed for routing packets in an intermediate node between a mobile node and a correspondent node in a packet-switched network, only one of said nodes being macro-mobility enabled, comprising at the intermediate node: —exchanging lower-layer-address-update-related messages with said macro-mobility enabled node; —mapping source address, destination address and potentially protocol parameters of lower-layer packets exchanged between the mobile node and the correspondent node in such a way that the macro-mobility enabled node can communicate with the other node as if the other node is also macro-mobility enabled, and such that the other node can communicate with the intermediate node as if the intermediate node is a non-macro-mobility-enabled node. Also associated devices, update methods for devices, and servers are disclosed.

Abstract: An exemplary technique is provided for use in a decentralized electronic transfer system. A first digital code that represents a first transaction is generated from a first user's secure repository to the first user's unsecure repository. The first digital code is sent to a secure storage memory related to the unsecure repository to be stored in an area of the memory. A processor related to the unsecure repository generates a second digital code that represents a second transaction from the unsecure repository to the second user's repository. The processor retrieves the first digital code stored in the secure storage memory and publishes the retrieved digital code to validate the first transaction. In addition, the processor publishes the second digital code to validate the second transaction.

Abstract: The invention concerns a method of managing computer memory, the method comprising the steps of maintaining (101) a page table entry for mapping a virtual address to a physical address and a cache comprising a plurality of data blocks and, in response to a reference to the virtual address, translating (102) the virtual address into the physical address by means of the page table entry and fetching (103) data from the physical address into the cache, wherein the page table entry comprises a plurality of indicators, each data block corresponding to an indicator, and, upon fetching the-data into the cache, the method comprises the further step of, in response to an indicator being set, zeroing (104) the corresponding data block. The invention further concerns a computer program product and a device therefor.
