Title:
METHODS AND DEVICES FOR TRANSMITTING DATA BETWEEN STORAGE AREA NETWORKS
Document Type and Number:
WIPO Patent Application WO2004068811
Kind Code:
A3
Abstract:
Methods and devices are provided for efficient transmission of data between storage area networks. According to some aspects of the invention, novel methods are provided for processing data packets sent by, or received from, a storage area network. Some such aspects of the invention involve storing a packet (or a portion of a packet) in a single memory location during an encapsulation or de-encapsulation process. Instead of repeatedly copying the packet during processing, pointer information is passed along that indicates the single memory location. In some aspects of the invention, the segment boundaries of a packet are retained after data transmission. If data in the packet need to be re-transmitted, the packet is re-transmitted with the same segment boundaries. Some aspects of the invention provide a "slim" TCP stack without a socket layer.
