What is HLD in network design?

High-Level Design (HLD) — is like a global overview of the network, with a basic description of all the modules and parts, without the unnecessary details, so that the reader can understand the main functions. Low-Level Design (LLD) — add details to the HLD.

What means HLD and LLD?

High Level Design in short called as HLD. Low Level Design in short called as LLD. 03. It is also known as macro level/system design. It is also known as micro level/detailed design.

What is difference between HLD and LLD in networking?

LLD is created on the footsteps of HLD and provides detailed and in-depth information of the HLD. Some terms related to HLD include Zoning, Traffic flow and high-level connectivity across various elements of the solution, while LLD is more related to terms like VLAN, IP address, port numbering etc.

What is an HLD document?

A High-level Design (HLD) is a slightly technical document for a (generally) non-technical audience. A High-level Design aims to provide all relevant stakeholders with a bird’s eye view of the solution’s architecture and design they will be receiving.

What are HLD used for?

High-level design (HLD) explains the architecture that would be used to develop a system. The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces.

What comes first HLD or LLD?

Sequential order in the design phase It is developed first in sequential order, which implies that the HLD is created before the LLD. It is developed after High-level design.

What is HLD and LLD in design phase of SDLC?

The HLD changes the client or business requirement into a high-level solution. The LLD changes the high-level solution to a comprehensive solution.

What is LLD software development?

Low-level design (LLD) is a component-level design process that follows a step-by-step refinement process. This process can be used for designing data structures, required software architecture, source code and ultimately, performance algorithms.

What is HLD in software engineering?

What is HLD? The HLD stands for High-Level Design, where the designer will only focus on the various models, like: The solution architect develops the High-level design, which is used to specifies the complete description or architecture of the application.

Who develops the high-level design (HLD)?

The solution architect develops the High-level design, which is used to specifies the complete description or architecture of the application. The HLD involves system architecture, database design, a brief description of systems, services, platforms, and relationships among modules. The HLD is also known as macro-level or system design.

What is LLD (low-level design)?

The LLD stands for Low-Level Design, in which the designer will focus on the components like a User interface (UI). The Low-level design is created by the developer manager and designers. It is also known as micro-level or detailed design.
