Network Architecture

The term “Network Architecture” describes the complete framework of an organization’s computer network. It provides a full overview of all the available resources. This framework is usually created in concert with network admins, network engineers, and other key IT personnel.

Network Architecture describes the complete framework of an organization’s computer network. The framework refers to the accessible physical components of the Network Architecture. It includes hardware components, device types, topologies, wireless connections, and network layout. It is important to keep track of a company’s Network Architecture as it grows and changes and review it regularly. These assessments will help identify potential pain points as well as look at opportunities for network growth.

Types of Network Architectures

Peer-to-Peer:

  • Good for small environments, usually up to 10 computers
  • Each computer must have specific permissions assigned
  • Sharing resources can be a problem
  • Security is a serious issue

Wide Area Network (WAN)

  • Aggregates various types, speeds, and links running a unrelated set of protocols together crossing various boundaries
  • Connect users and applications connected to various LANs
  • Latency and bandwidth issues often cause enterprise WANs to suffer performance issues

Software-Defined WAN (SD-WAN)

  • Manages network connections for enterprise branch offices, data centers, and cloud/SaaS services
  • Creates a network overlay that abstracts network hardware and transport characteristics from the applications that use the network
  • Offers superior network agility
