Question

What is an HLD [High Level Design] with reference to network design, and can you provide a sample?

Answer 1

HLD [High Level Design] with reference to network design:

• There must be limitations for LAN, MAN, WAN network related with the coverage area, memory space requirement and violation of privacy scheme.
• The best solution to overcome these to use High Level Design (HLD) with reference with network design.
• To do these first establish Virtual Private Network (VPN) among the all available network. VPN is a software mechanism that allows authorized remote users to access corporate network resources safely.
• To do high level design the Peering design strategy must be used. It includes high density and environmentally efficient edge routers that follows with topology and peer terminals that are connected with actual network with core connectivity as shown in figure below:
• In above figure we get the architecture of HLD reference model for network design. Following are the advantages for above model:

1. It improve the network efficiency.
2. Network get simplified and easy to use.
3. It becomes more secure.
4. Avail facility for peering strategy.
5. Proper peer and topology distribution.
6. Platform independent.
