Introduction

• Network management is essential for companies.
• Exchanging information become more efficient.
• Network management needs protocols.
• Two important protocols
• Simple Network Management Protocol (SNMP)
• Common Management Information Protocol (CMIP)

SNMP

• Why SNMP ?
• SNMP is located in Application layer.
• SNMP responsible for exchanging data between
  network devices.
• SNMP has three mechanisms
• Managed devices Collecting and sorting data.
• Agents Managing data.
• Network management system (NMS) Implements the
  application

Advantages and Disadvantages

• Advantages
• Easy to use
• Expandability
• Disadvantages
• Weak security
• Too simple!

CMIP

• Created in 1988 by Internet Activities Board
  (IAB).
• Government and Corporations invested.
• Common Management Information Services Element
  (CMISE).
• Information exchange between management stations
  and management agents.
• Remote Operations Service Element (ROSE).
• Sends and receives Protocol Data Units (PDUs).

CMIP

• 11 Data units or operations
• M-EventReport
• M-EventReport-Confirmed
• M-Get
• M-Linked-Reply
• M-Set
• M-Set-Confirmed
• M-Action
• M-Action-Confirmed
• M-Create
• M-Delete
• M-Cancel-Get

SNMP vs. CMIP

• Similar operations

SNMP vs. CMIP

• What SNMP is to TCP/IP is what CMIP is to OSI.
• MIB
• More objects in CMIP.
• Security

Conclusion

• In our opinion
• SNMP and CMIP should not be compared.
• LANs and WANs
• SNMP better for LANs CMIP better for WANs
• Analogies
• High-level programming language and assembly
  language.
• Like two different religions.
• Religions should not be compared.
• Network Manager acts as God.
• Sacrifices (celibacy).
• Services (help the poor).
