Management Computer Network

1. Details:
• Definition and scope of the Computer Network Management
• Network topology, VLSM, CIDR
• Static IP, ARP, BOOTP, DHCP, Implementation
• Server Farm, Virtual LANs
• Accesslist, Extended Accesslist, URL Based ACL
• IP Address Management
• Routing Protocol, Classless InterDomain Routing, Route Summarization / agregation
• IGP, EGP, BGP, Load Balancing
• Network Address Translation, Port Address Translation, Masquerade
• Demilitarized Zone (DMZ)
• SNMP and network monitoring, MRTG, Cacti, Packet Analyzer
• Network Intrusion Detection

2. Management:
• In general terms, include:
- Planning (Planning)
- Organization (Organizing)
- Monitoring
- Accounting and
- Controlling of an activity
3. Definition:
 Computer Network / Communications
• Includes:
- Asset Hardware: Computers, Hubs, Switching, Router, PBX, Central Phone, Devices
 Transmission / Trunking
- Asset Software: Operating Systems (Operating System) / Network Operating System, Applications, Etc..
4. Network Management:
• It is the ability to apply a method for:
- Monitoring of a network
- Controlling a network
- Plan (planning) source (resourses) as well as system components and computer network & communications
5. Network Management targets:
• Keeping the network running
• Maintaining Network Performance
• Reduced cost of ownership (giving added value)
 Maintain order for Fixed Network Running
• Keeping the system in order to remain in operation
• Gather information about the "health" of a network
 Maintaining Network Performance
• The network must be able to bring benefits (continuous -> Optimal)
• Understand when customers become dissatisfied
• Maintaining the agreed QoS
• Network Management is able to provide the necessary information u / analysis of short-term and long term
 Reduce Cost of Ownership
• The device is installed is an expense (cost)
• Management: Reactive (a reactive action against the problems) sometimes do not notice how much the cost u / finish
• Management: Proactive (an act of planned) is expected to lower costs as the management bersifatreaktif
6. Limitation of Network Management:
 Computers / Communication
• Network Management is an application to manage the resources in the form
Hardware / software of a network
• Able to provide accurate information required for business
7. Network Management Problems In Implementation:
• Multi Vendor:
- Hardware = A variety of technologies, and services (Voice, Video, Message, Data)
- Software = Operating System, Protocols, and Applications
8. Iplementasi Solutions Network Management:
• Total Solution (Solution Architecture) more or less single Vendor
• Standardization (Following an, rules / rule to be mutually agreed)
9. Total Solution
• Pros:
- Simple in its application
• Disadvantages:
- Dependence
10. Standardization:
• Advantages:
- Not dependent on a vendor
• Disadvantages:
- Very complex in its implementation
11. Glossary:
• Subnetting
• Switching
• Routing
• Bridging
• Repeater
• Dst
