Module 4 Discussion
What are the key high-speed networking services available for wide-area networking?
Key high-speed networking services available for wide-area networking (WAN) include leased
lines, Frame Relay, ATM (Asynchronous Transfer Mode), MPLS (Multiprotocol Label
Switching), and Ethernet WAN services (Cisco, n.d.).
Which one would you recommend for a college campus?
The choice of a specific WAN service for a college campus will depend on factors like budget,
the required bandwidth, reliability, and security needs. For most college campuses, a
combination of technologies might be the best approach. I would suggest considering a
combination of MPLS (Multiprotocol Label Switching) and SD-WAN (Software-Defined Wide
Area Network). They would use MPLS for critical applications and services that require
guaranteed Quality of Service (QoS), low latency, and high reliability. This can include services
like VoIP, video conferencing, and mission-critical data applications. MPLS is known for its
reliability and ability to prioritize traffic. On the other side, they would Implement SD-WAN to
complement MPLS for more flexible and cost-effective connectivity for non-critical traffic and
to optimize the use of multiple WAN links, such as broadband and cellular connections. SD-
WAN can help balance the load and provide redundancy, ensuring that the network remains
robust and adaptable.
What are the uses for value added network (VAN) and very private network (VPN)? How
do VAN and VPN work?
VAN is a private network that offers additional services on top of traditional connectivity, such as
enhanced security, Quality of Service (QoS), and monitoring. They are useful for organizations
with specific needs, like colleges looking to provide secure, reliable connections for students and
staff (Frankenfield, 2022).
VPNs create secure, encrypted connections over public networks like the internet. They are
essential for securing data in transit and providing remote access for students and faculty. VPNs
can be layered on top of other WAN services, adding an extra layer of security (
