this slides is about comparison of newer WAN technology and traditional WAN technologies

1. Newer WAN technology

2. Difference between traditional and new WAN technology In terms of connectivity. Modern WANS have more connectivity options that traditional WANs doesn’t. Enterprises now require faster and more flexible WAN connectivity options. Traditional WAN connectivity options have rapidly declined in use because they are either no longer available, too expensive, or have limited bandwidth.

3. Digital subscriber line(DSL) DSL is a modem technology that uses existing telephone lines to transport high-bandwidth data, such as multimedia and video, to service subscribers. DSL:- less expansive Speed depend on type(asymmetric DSL, symmetric DSL, very high bit-rate DSL) But it has distance limitations DSL uses a phone jack

4. Continue Compared to traditional leased line:- used Use different carrier to increase the speed leased line needs physical cables installed One user uses the bandwidth of that line dedicated and private connection T1 : 1.5Mbps---T4:274Mbps Uses CSU/DSU to connect to the network

5. Metro ethernet A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is a metropolitan area network that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or for internet access. Less expensive and more common than specialized serial ports used in a CSU/DSU Technology used by service provider is hidden from customer and they only need to connect their network’s router to a Smart Jack Allow authentication occur over ethernet using like PAP protocol Compared to channel service unit(CSU) and Data service unit(DSU) Is used for leased lines Used to connect to network, Expensive, Balky and old

6. Cable modem Hybrid Fiber-Coax (HFC) distribution network is a cable television infrastructure containing both coaxial and fiber-optic cabling. Mostly is used for cable television transmit and receive over cable television infrastructure Specific frequency ranges are used for upstream and downstream data transmission as determined by Data-Over-Cable Service Interface Specification (DOCSIS) and compared to satellite modem Less speed, Delay and Weather issues

7. Long-range wireless Long-range wireless is the sharing of information between wireless devices or computers. Also called WiFi , wireless technology typically transmits data at high speeds and allows users to connect from distances of up to 64.37 km. One of the most important components of long-range Wi-Fi systems is the long-range antennas. Without them, it would be impossible to send and receive signals at high speeds over long distances. The type of antenna and the strength of the antenna will determine the range and the coverage area of the signal. Wi-Fi, Cellular Networks, Satellite Communication, Microwave Communication, RFID (Radio-Frequency Identification), Wireless Sensor Networks

8. Multi protocol label switching (MPLS) Multiprotocol Label Switching (MPLS) is a switching mechanism used in wide area networks (WANs). MPLS uses labels instead of network addresses to route traffic optimally via shorter pathways. Allows traffic to be dynamically routed based on load conditions and path availability Used by service providers for forwarding data in the backend, the customer remains unaware of the details Label switching is more efficient than Layer 3 IP address routing Is fast because of switching and labelling Support both Frame Relay and ATM on the same MPLS backbone

9. Advantage of MPLS Improve Uptime - by sending data over an alternative path in less than 50 milliseconds (if one exists). MPLS also reduces the amount of manual intervention your network provider has to do to create a WAN, reducing the likelihood of human error bringing down your circuit. Create Scalable IP VPNs - with MPLS it's easy to add an additional site to the VPN. There is no need to configure a complex mesh of tunnels, as is common with some traditional approaches.

10. Continue Improve Bandwidth Utilisation - by putting multiple types of traffic on the same link, you can let high priority traffic borrow capacity from lower priority traffic streams whenever required. Conversely, when the lower priority traffic needs to burst beyond its usual amount of bandwidth, it can use any capacity that's not being used by higher priority services. Hide Network Complexity - an MPLS connection between two sites can be configured to act like a long ethernet cable, with the hops involved hidden from view. This is sometimes known as VPLS (Virtual Private LAN Service).

11. Continue Reduce Network Congestion - Sometimes the shortest path between two locations isn't the best one to take, as congestion has made it less attractive (at least for the time being). MPLS offers sophisticated traffic engineering options that enable traffic to be sent over non-standard paths. This can reduce latency (the delay in sending/receiving data). It also reduces congestion on the paths that have just been avoided as a result of traffic engineering Improve User Experience - by prioritizing time-sensitive traffic such as VoIP. Multi-Protocol Label Switching offers multiple Classes of Service, enabling you to apply separate settings to different types of traffic.

12. Conclusion In terms of these factors Cost: Traditional WAN technologies may involve higher upfront costs, while newer technologies like SD-WAN may offer cost savings, particularly in terms of using lower-cost internet connections. Scalability: Consider the scalability requirements of your organization. SD-WAN, with its agility and flexibility, may be better suited for businesses with dynamic and growing networking needs. Performance: Depending on the criticality of your applications, the performance characteristics of the WAN technologies will be crucial. MPLS is known for its reliability and QoS capabilities, while SD-WAN focuses on optimizing performance through intelligent routing.

13. Continue Deployment and Management: Evaluate the ease of deployment and management. SD-WAN, being software-defined, often provides a more streamlined and centralized approach to network management. Abdishakur.
