Network topology is essential to network configuration, as it determines the arrangement of a network and defines how nodes connect. Here are six common types of network topologies.
No two networks are designed and built the same. One business might have drastically different network deployment goals from another. Network professionals tailor each system to meet the levels of access, control and performance based on the goals of a business.
That said, enterprise-grade networking technologies come with their own limitations, so network professionals must build networks based on how the equipment operates. Most network topologies -- which include networking equipment and supplemental software -- are flexible, but they also have a few specific deployment methods.
Here's a look at six popular types of network topologies. Some legacy topologies are rarely used, while others are newer and provide more performance, reliability and security. Let's look at each topology type and how each operates.
For most organizations, SD-WAN and security have become closely intertwined decisions. This interdependency can be viewed in a couple of ways, each of which can offer benefits for enterprises.
Software-defined wide area networking, or SD-WAN, is the next frontier for the network edge. Multiple analysts report that the SD-WAN market is in the billions of dollars, with an annual growth rate in the 25% to 35% range. Managed service providers and carriers globally are increasingly deploying managed SD-WAN services to reach new markets. Almost all networking and security vendors have SD-WAN offerings, complicating the decision when choosing an SD-WAN solution.
Security and WAN connectivity decisions have become a collaborative decision between the security and networking teams. Prior to this, enterprise networking teams were responsible for setting up connectivity to major company locations, while connections to branches and remote offices fell to the enterprise WAN manager. In the meantime, dedicated security teams were tasked with procuring, deploying, and managing firewalls.
