We propose a novel network interface architecture:
``Memory-Based Processor II (MBP2)'' 
which supports efficient middle-grained memory-based
communications, legendary TCP/IP and UDP/IP.
Although the hardware cost of the MBP2
is almost as same as that of 
conventional Network Interface Cards (NICs),
in memory-based communications the MBP2 system is much
superior to the NIC systems.
