Abstract
Data replication can be supported efficiently in a protocol offload device (such as a protocol offload device to offload transport layer protocol processing from a host) by supporting a shared memory (SHM) abstraction for the send and receive buffers that are used in protocol offload devices. The protocol offload send and receive buffers are accessed using a per offloaded connection virtual address method that maps transport protocol sequence numbers (such as TCP protocol sequence numbers), to memory locations within buffers, and, for example, either page tables and paged memory or segment tables and segmented memory tables are used to access the memory.
