Topics Under Discussion

• Framing, synchronization
• TCP is byte stream oriented current draft has a
  proposed mechanism to detect the FC frame
  boundaries at the receiving end

  bits
• Security
• Looking into the use of TLS and IPSec
• Order of delivery
• Discovery of FCIP gateways
• Error Recovery
• FC, FCP, TCP timeouts

Alignment with FC-BB-2 Effort

• FC-BB-2 efforts will be complementary to IETF
  efforts
• FC-BB-2 will address any FC issues related to
  link level timeout etc.
