What common networking protocol is used as cable services transition from broadcast to switched services?

The transition from broadcast to switched services in cable networks relies heavily on Gigabit Ethernet (GigE) technology. This networking protocol is designed to improve efficiency and bandwidth capacity, facilitating faster data transfer rates compared to older protocols. GigE can handle large amounts of data, making it suitable for switched services where multiple data streams can be transmitted simultaneously without collisions, enhancing performance and reliability.

This transition exemplifies the need to accommodate higher demands for data throughput and service quality in modern networks. Unlike older protocols such as Token Ring or Frame Relay, which served their purposes in specific contexts, Gigabit Ethernet directly addresses the requirements of contemporary cable services by providing a robust and scalable infrastructure. This makes it the preferred choice for cable systems evolving towards more sophisticated and demand-driven service models.
