What does the term “scalability” refer to in Carrier Ethernet?

In the context of Carrier Ethernet, scalability specifically refers to the capacity of a network to expand and accommodate growth without requiring a complete redesign of the existing infrastructure. This quality is crucial for service providers who need to support an increasing volume of data or a rising number of customers without undergoing significant upgrades or major architectural changes.

Scalability ensures that as demand grows—whether through added subscribers, higher data rates, or additional services—the network can adapt efficiently by adding resources, such as bandwidth or additional hardware. This characteristic helps maintain performance and reliability while minimizing disruption and cost, making it a fundamental aspect of modern networking solutions.

The other choices do not align with the concept of scalability. While managing personnel efficiently may contribute to overall operational success, it doesn't pertain to network infrastructure. Reducing service charges speaks to pricing strategies rather than capability to expand a network. Switching from wired to wireless networks relates to specific technology choices rather than the ability to grow existing network capacity.
