Chapter 8. OSI Session, Presentation, and Application Layers

Upon completing this chapter, you will be able to:

• Relate the addressing schemes of Internet Small Computer System Interface (iSCSI), Fibre Channel Protocol (FCP), and Fibre Channel over TCP/IP (FCIP) to the SCSI architecture model (SAM) addressing scheme

• Discuss the iSCSI name and address assignment and resolution procedures

• Differentiate the FCIP functional models

• List the session establishment procedures of iSCSI, FCP, and FCIP

• Explicate the data transfer optimizations of iSCSI, FCP, and FCIP

• Decode the packet and frame formats of iSCSI, FCP, and FCIP

• Explain the delivery mechanisms supported by iSCSI, FCP, and FCIP

This chapter explores the operational details of iSCSI, FCP, and FCIP in depth. Currently, this chapter does not examine iFCP because iFCP has limited industry support. The primary focus of this chapter is OSI session layer functionality, but we also explore certain aspects of OSI presentation and application layer functionality.
