Businesses are constantly expanding into new branches in different cities. We utilise the infrastructure of the Internet Service Provider to offer connectivity between the two branches. Wide area networks are connections to networks that are not part of the company’s network (WAN). Cisco, a manufacturer of networking hardware, offers entry-level CCNA certification in information technology (IT). If you are here to know the WAN Connection Types in CCNA, You can join the CCNA Course in Chennai at FITA Academy.
For remote access to our resources, the ISP offers us a form of WAN connection that is subscription-based. The Internet is a major additional WAN application. Our local internet service providers’ WAN makes it possible for us to connect to the Internet. Below, we’ll go through each WAN connection type.
Wide Area Network Connectivity
A LAN can be extended across a significant geographic distance using a wide area network (WAN), which is a telecommunications network. Technically, Layer 3 devices like routers or firewalls can connect two or more local area networks to a WAN.
Based on the subscription, most WAN IP addresses to link to ISPs using PPPoE (Point-to-Point Protocol), Static Public IP Address, and Dynamic Public IP Address. Because we only have one-of-a-kind public IP addresses that another client cannot utilise, stable public IP addresses are more costly than dynamic and PPPoE.
Private IP addresses cannot be routed over the WAN or the Internet; they can only be routed on the local network. The LAN and WAN infrastructure can be seen in the diagram below.
WAN Connection Types
To provide Internet connectivity, there are numerous WAN links. The most popular choices for WAN connection from a Network provider are listed below. Learn advanced CCNA Course Online for the Best Coaching. The trainers from the FITA Academy are Well- Experienced in CCNA Courses.
This kind of WAN connection is a fixed bandwidth, dedicated point-to-point connection. Your system will have a secure and dependable connection, greater bandwidth, and superior quality of service if you use a leased line. On the other hand, leased lines are expensive and invaluable because of the ongoing physical connection.
Digital Subscriber Line
Over fixed telephone lines, digital signals are transmitted using DSL as a medium. On the phone, you can use the Internet because it operates on a different bandwidth. DSL, an earlier idea, provides an average speed of 6 Mbps. The benefit of DSL is that it offers steady speed and does not share bandwidth.
Fiber Internet Access
This is a brand-new broadband connection that offers clients high-speed internet service. Due to its ability to handle faster rates than other cables, it is also frequently utilised in telecom backhaul links.
Multi-Protocol Label Switching (MPLS)
Rather than IP addresses or Layer 3 headers, MPLS is a kind of VPN that uses labels to forward packets. For customer sites, it offers the best routing and security. In MPLS, the network operator takes part in the routing for the client.
Most of us use mobile data on our phones to access the Internet. The connection types for wireless WAN that are most often used include 3G, 4G, LTE, and 5G. Services offered by a nearby ISP to give mobile devices wireless Internet access using cellular stations. It uses particular frequencies to give users a strong signal and extensive coverage.
