Study Notes
- Peer-to-peer network: every device acts as both a server and a client, enabling direct communication between devices for data access
- Advantages of peer-to-peer networks: low cost, easy application deployment, no need for additional servers
- Disadvantages of peer-to-peer networks: difficult administration, security concerns due to distributed authentication
- Client-server communication: clients communicate with a central server, providing easy administration and better performance
- Local area network (LAN): a network within a building or single location, usually with high throughput and fast communication
- Metropolitan area network (MAN): a larger network covering a city or metropolitan area, usually provided by third-party providers
- Wide area network (WAN): a network connecting locations over a large distance, generally slower than LAN or MAN, includes terrestrial and satellite connections
- Wireless Local Area Network (WLAN): a wireless LAN using 802.11 technology, limiting geographical area but extendable with multiple access points
- Personal area network (PAN): short-range wireless connections between devices, such as Bluetooth headsets and car audio systems
- Campus area network (CAN): connecting multiple buildings on a campus, often using high-speed ethernet and private LAN connections.- MPLS (Multiprotocol Label Switching) is a network technology used for forwarding data between networks by labeling data packets.
- Edge routers in MPLS networks insert labels onto data packets and forward them through the provider switch network.
- With MPLS, initial configuration is required to define sites and labels for data switching to those locations.
- Dynamic connections in wide area networks (WANs), such as Multipoint Generic Router Encapsulation (MGRE) and dynamic multipoint VPNs, create links only when needed and tear them down when not in use.
- Dynamic multipoint VPNs enable direct communication between sites without requiring them to go through a main office.
- SD-WAN (Software Defined Wide Area Network) allows network layout to be defined however desired, making it especially useful for accessing cloud-based applications.
- SD-WAN determines data routing based on the type of services required, resulting in a more efficient network.
- Cloud-based services have moved data and servers from central data centers to the cloud, requiring WANs to adapt and send data directly to cloud resources.
- SDWAN enables instant access to cloud-based resources without requiring data to hop through a central data center.
