Abstract

The invention relates to a storage agent system used for cross-IPv4 and IPv6-network processing, comprising a main control unit, an IPv6 input buffer, an IPv4 input buffer, an IPv4 output buffer, an IPv6 output buffer, a PDU analyzer, a PDU constructor, a command analytic unit, a data processing unit, a port mapping tank, a target node registration management module and a communication manager. The method includes that a storage request and storage data packet from an initiator node in the IPv6 network are subject to analyzing, mapping and processing by virtue of the system and are then sent to corresponding storage target node; and a storage response packet and data packet which are sent to the IPv6 node by the target node are subject to buffering and conversion processing by virtue of the system and are then forwarded to the IPv6 initiator node. The invention provides intermediate conversion and expedited forwarding functions for communication and data transmission of IPv6 storage user and IPv4 storage system, and efficiency that an IPv6 uses storage service is improved.

Description

technical field [0001] The invention relates to network storage technology, in particular to a storage agent system and method for processing cross-IPv4 and IPv6 network storage services during the IPv6 transition period. Background technique [0002] With the rapid development of the Internet and the popularization and application of IPv6 technology, the degree of integration between IPv6 and the existing IPv4 network is getting higher and higher. However, the infrastructure of IPv4 network is very extensive, and the transition from IPv4 network to IPv6 cannot be accomplished overnight. IETF's IPv6 Network Interoperability Working Group (v6ops) also pointed out that there will be no large-scale, extensive, and overall migration and transition of the network, and IPv4 and IPv6 technologies will coexist and interoperate for a long time in the next ten years or even longer. operate. During the transition period, IPv6 and IPv4 networks are mainly interconnected through dual s...
