Preferred WAN Access Technology

A

In a small office/home office (SOHO) architecture, the WAN access technology preferred is typically broadband cable access.

Broadband cable access provides high-speed internet connectivity using the same infrastructure as cable television. It offers a high-speed downstream (from the internet to the user) and a relatively lower upstream (from the user to the internet) bandwidth.

Broadband cable access is a cost-effective option, as it is readily available in many areas and the equipment required to use it is typically affordable. It is also easy to set up and does not require any special equipment or technical expertise.

Frame-relay packet switching, on the other hand, is an older WAN access technology that is no longer widely used. It was a popular choice in the past because it provided a reliable, cost-effective means of transmitting data over long distances. However, frame-relay has largely been replaced by more modern technologies such as MPLS (Multiprotocol Label Switching) and Ethernet.

Dedicated point-to-point leased lines are another option for SOHOs, but they are typically more expensive than broadband cable access. Leased lines provide a dedicated connection between two points and are often used for mission-critical applications that require high levels of reliability and security.

Integrated Services Digital Network (ISDN) switching is another older technology that is no longer widely used. It provided digital voice and data services over existing telephone lines. However, ISDN has largely been replaced by VoIP (Voice over IP) and other modern voice technologies.

In summary, broadband cable access is the preferred WAN access technology for SOHOs due to its affordability, ease of setup, and availability.
