Abstract: A network information transmission system. The network information transmission system includes a packet handling device including a control plane configured to open a remote direct memory access (RDMA) connection with a destination external to the network information transmission system, an encapsulator configured to encapsulate one or more packets traversing the packet handling device, producing one or more encapsulated packets, and a transmitter configured to transmit the one or more encapsulated packets, via the RDMA connection, to the destination external to the network information transmission system. Related apparatus and methods are also described.

Abstract: A method including providing: a switching device including a main mapping unit configured to provide a main mapping which maps virtual addresses to direct addresses; management logic configured to store a connection tracking table stored in memory and configured for storing a plurality of connection mappings each including a virtual-to-direct mapping from a virtual address to a direct address; and a migrated connection table stored in memory and configured for storing a plurality of migrated connection mappings each including a virtual-to-migrated-direct mapping from a virtual address to a migrated direct address. Upon receiving an indication that a direct address has changed: when the indication that a direct address has changed includes an indication that a direct address stored in one or more connection mappings in the connection tracking table is not active, copying the one or more connection mappings from the connection tracking table to the migrated connection table, when the indication that a direct address has changed includes an indication that a new direct address has become active, creating one or more connection mappings in the migrated connection table, and altering the main mapping in accordance with the direct address change.
