Technologies for Enhancing Network Performance

Learning Outcomes

  • Demonstrate network administration and management skills.
  • Identify and use network tools for troubleshooting.
  • Understand implications of major protocols and standards.
  • Apply technologies to improve performance of data, voice, and video transmission.

Network Protocols

  • Definition: Rules for communication between network devices.
  • Importance:
    • Standardizes communication across devices.
    • Enables seamless data transition.
    • Ensures reliability and efficiency.

Key Networking Protocols

  • TCP/IP: Manages data transmission on the internet; splits data into packets.
  • HTTP: Transfers web resources; works with TCP/IP for website loading.
  • Ethernet: Governs wired communication within local networks (LANs).

International Standards

  • IEEE 802.3: Standard for wired LANs ensuring device compatibility.
  • ISO/OSI Model: Framework for data travel across networks in seven layers.

Importance of Protocols and Standards

  • Interoperability: Allows devices from different manufacturers to communicate.
  • Scalability: Enables easy network expansion.
  • Security: Guidelines for encryption and firewall implementation.

Gigabit Switches & Routers

  • Gigabit Switch: Connects multiple devices within a LAN, enabling high-speed data sharing.
    • Features: Speeds up to 1 Gbps, creates multiple communication channels.
  • Router: Connects different networks and routes data.
    • Features: Assigns IP addresses, provides network security.

Importance of Gigabit Switches and Routers

  • Data Routing: Ensures efficient data travel between networks.
  • Connectivity: Provides internet access to local networks.

Types of Gigabit Switches

  • Unmanaged Switch: Simple plug-and-play.
  • Managed Switch: Configurable for larger networks.
  • Smart Switch: Limited management capabilities.
  • PoE Switch: Supplies power and data.

Quality of Service (QoS), VoIP, and Video Compression

  • QoS: Manages and prioritizes data traffic; important for real-time applications.
  • VoIP: Enables voice communication over the internet; cost-effective and flexible.
  • Video Compression: Reduces video file size for smoother streaming on bandwidth-limited networks.

Benefits

  • QoS ensures critical applications function during peak times.
  • VoIP allows cost-effective communication anywhere with an internet connection.
  • Video compression enhances user experience during streaming, adapting to network conditions.
