Title: Performance of Large LAN Applications


1
Performance of LargeLAN Applications
  • Jeremy Bohannon Bryan Garcia
  • Lori Garcia Scott McCumsey
  • Steve Potts

2
Base Network Architectures
  • Traditional Mainframe Environments
  • Used primarily for legacy applications
  • Client/Server
  • Most newer applications
  • Net Centric
  • Very thin client networks
  • Combination

3
LAN Network Evolution
4
Examples of LAN Applications
  • E-mail
  • ERP (Enterprise Resource Planning)
  • CRM (Customer Relations Management)
  • MRP (Material Requirements Planning)
  • Proprietary applications created in-house to meet
    business needs

5
Key Issues for Applications Availability and
Operations
  • Concurrent Users
  • Speed
  • Response Time / Latency
  • Real-Time Information
  • Network Traffic
  • Cross-Platform Activity (Legacy systems)
  • Sharing Data Between Applications
  • Security
  • Remote Users

6
Criteria For Selecting LAN Technology
  • Bandwidth
  • New Technology
  • Cost
  • Interoperability
  • QoS
  • Manageability
  • Scalability

7
Selecting the Right LAN Backbone Technology
  • FDDI
  • ATM
  • Frame Relay
  • Ethernet
  • Gigabit Ethernet

8
Signs Your LAN is in Distress
  • Speed or lack of speed is the most common clue
    that the network is in distress
  • Difficulty installing new enterprise applications
    such as E-mail, Internet access, etc.
  • Overloaded servers
  • Slow client workstations
  • Increased failure of network components

9
Understanding Your Network BASELINING
  • A Baseline is a collection of performance
    measurements captured during peak loads.
  • Useful in diagnosing a misbehaving network.
  • Tells you if performance-enhancing changes are
    actually working.
  • Network baseline statistics include
  • Peak and average network utilization
  • Average number of errors
  • Average number of collisions
  • Monitoring equipment collects statistics so that
    you can review and compare.

What is ERP?
  • Enterprise Resource Planning (ERP) provides
    companies with a plan to integrate all
    departments and functions within the company by
    implementing a complete software solution that
    runs off a single, integrated database.
