Design Methodologies
The first part of the book covers design methodologies, which are the processes and techniques that guide network design. Design methodologies are important because they help you define the requirements, goals, constraints, and scope of a network project. They also help you analyze, evaluate, and document network solutions. In this part, you will learn how to apply three main design methodologies:
PBM: Problem-Based Methodology, which is a structured approach that focuses on identifying and solving network problems.
Network characterization: which is a process of collecting and analyzing data about an existing network's performance, capacity, availability, security, and functionality.
Top-down/bottom-up approaches: which are two complementary perspectives that help you design networks from different angles. The top-down approach starts with the business goals and user needs and then derives the network requirements and solutions. The bottom-up approach starts with the existing network infrastructure and then identifies the gaps and improvements needed to meet the business goals and user needs.
PBM: Problem-Based Methodology
PBM is a design methodology that follows six steps:
Identify: Define the problem statement, scope, stakeholders, assumptions, constraints, risks, and success criteria.
Analyze: Gather information about the current network state, such as topology, devices, protocols, traffic patterns, performance metrics, etc.
Synthesize: Generate possible network solutions that address the problem statement and meet the requirements. Compare and contrast different design options based on their advantages, disadvantages, costs, benefits, etc.
Evaluate: Test and validate the proposed network solutions using simulation tools, prototypes, pilots, etc. Verify that they meet the success criteria and resolve the problem statement.
Implement: Deploy the selected network solution in phases using change management procedures. Monitor and troubleshoot any issues that arise during implementation.
Optimize: Review and measure the results of the implemented network solution. Identify any areas for improvement or enhancement. Document and communicate the lessons learned and best practices.
Network Characterization
Network characterization is a design methodology that involves collecting and analyzing data about an existing network's performance, capacity, availability, security, and functionality. Network characterization helps you understand how a network operates, what are its strengths and weaknesses, what are its current and future needs, and what are its opportunities for improvement or expansion. Network characterization consists of four steps:
Data collection: Gather quantitative and qualitative data about the network using various sources and methods, such as interviews, surveys, audits, inventories, logs, reports, diagrams, etc.
Data analysis: Process and interpret the data using various tools and techniques, such as spreadsheets, graphs, charts, statistics, etc.
Data validation: Verify the accuracy and completeness of the data using various methods, such as cross-checking, sampling, testing, etc.
Data documentation: Organize and present the data using various formats, such as tables, reports, dashboards, etc.
Design Objectives
The second part of the book covers design objectives, which are the principles and guidelines that help you achieve optimal network design. Design objectives are important because they help you align your network design with the business goals and user needs. They also help you ensure that your network design is modular, hierarchical, scalable, resilient, and fault-tolerant. In this part, you will learn how to achieve five main design objectives:
Modularity: which is the degree to which a network is composed of discrete and interchangeable components that can be added, removed, or replaced without affecting the whole system.
Hierarchy: which is the degree to which a network is organized into layers or levels that have different roles and functions.
Scalability: which is the degree to which a network can accommodate growth or change in traffic volume, users, applications, devices, etc. without degrading performance or quality.
Resilience: which is the degree to which a network can recover from failures or disruptions and maintain normal operations.
Fault domains: which are the areas of a network that are affected by a failure or disruption. Fault domains help you isolate and contain failures and minimize their impact on other parts of the network.
Modularity
Modularity is a design objective that helps you create a network that is flexible, manageable, and adaptable. Modularity allows you to divide a large and complex network into smaller and simpler units that can be easily modified or replaced. Modularity also allows you to reuse common components and designs across different parts of the network. Modularity has several benefits for network design:
It reduces complexity and improves readability by breaking down a network into logical and functional blocks.
It increases flexibility and adaptability by allowing you to add, remove, or change network components without affecting the whole system.
It enhances manageability and maintainability by allowing you to troubleshoot and update network components individually or in groups.
It improves performance and efficiency by allowing you to optimize network components for specific functions and requirements.
It facilitates scalability and growth by allowing you to expand or upgrade network components as needed.
HierarchyHierarchy is a design objective that helps you create a network that is structured, organized, and consistent. Hierarchy allows you to arrange a network into layers or levels that have different roles and functions. Hierarchy also allows you to define clear boundaries and interfaces between different parts of the network. Hierarchy has several benefits for network design:
It reduces complexity and improves readability by separating a network into distinct and manageable segments.
It increases flexibility and adaptability by allowing you to modify or replace network segments without affecting other segments.
It enhances manageability and maintainability by allowing you to control and monitor network segments individually or in groups.
It improves performance and efficiency by allowing you to optimize network segments for specific functions and requirements.
It facilitates scalability and growth by allowing you to add or upgrade network segments as needed.
Scalability
Scalability is a design objective that helps you create a network that can accommodate growth or change in traffic volume, users, applications, devices, etc. without degrading performance or quality. Scalability allows you to plan ahead for future needs and demands of your network. Scalability also allows you to adjust your network resources and capabilities as needed. Scalability has several benefits for network design:
It reduces complexity and improves readability by avoiding unnecessary or redundant network components.
It increases flexibility and adaptability by allowing you to add, remove, or change network resources without affecting other resources.
It enhances manageability and maintainability by allowing you to balance and distribute network resources across different parts of the network.
It improves performance and efficiency by allowing you to optimize network resources for specific functions and requirements.
It facilitates scalability and growth by allowing you to expand or upgrade network resources as needed.
Resilience
Resilience is a design objective that helps you create a network that can recover from failures or disruptions and maintain normal operations. Resilience allows you to design a network that is reliable, available, and fault-tolerant. Resilience also allows you to implement backup and recovery mechanisms for your network. Resilience has several benefits for network design:
It reduces complexity and improves readability by avoiding single points of failure or bottlenecks in the network.
It increases flexibility and adaptability by allowing you to switch or reroute network traffic in case of failures or disruptions.
It enhances manageability and maintainability by allowing you to detect and diagnose failures or disruptions quickly and easily.
It improves performance and efficiency by allowing you to minimize the impact of failures or disruptions on network performance or quality.
It facilitates scalability and growth by allowing you to add or upgrade network components without compromising network reliability or availability.
Fault Domains
Fault domains are the areas of a network that are affected by a failure or disruption. Fault domains help you isolate and contain failures and minimize their impact on other parts of the network. Fault domains also help you identify and prioritize the critical and non-critical components of your network. Fault domains have several benefits for network design:
They reduce complexity and improve readability by dividing a network into smaller and simpler units that can be easily analyzed or repaired.
They increase flexibility and adaptability by allowing you to isolate or protect network components from failures or disruptions.
They enhance manageability and maintainability by allowing you to troubleshoot and update network components within a fault domain without affecting other fault domains.
They improve performance and efficiency by allowing you to optimize network components within a fault domain for specific functions and requirements.
They facilitate scalability and growth by allowing you to expand or upgrade network components within a fault domain without affecting other fault domains.
Enterprise Network Design
The third part of the book covers enterprise network design, which is the process of designing networks that support the business goals and user needs of an organization. Enterprise network design consists of three main components:
Campus: which is the physical infrastructure that connects the devices and users within a single location, such as an office building, a campus, or a data center.
Enterprise: which is the logical infrastructure that connects the devices and users across multiple locations, such as branch offices, remote sites, or cloud services.
Branch: which is the combination of physical and logical infrastructure that connects the devices and users at a remote location, such as a retail store, a home office, or a mobile device.
Campus Network Design
Campus network design is the process of designing networks that connect the devices and users within a single location. Campus networks typically use Ethernet LAN technologies, such as switches, routers, firewalls, wireless access points, etc. Campus networks are usually organized into three layers:
Access: which is the layer that connects the end devices, such as PCs, laptops, phones, printers, etc. to the network. The access layer provides connectivity, security, quality of service, power over Ethernet, etc. for the end devices.
Distribution: which is the layer that connects the access layer switches to the core layer switches. The distribution layer provides aggregation, routing, filtering, redundancy, load balancing, etc. for the access layer.
Core: which is the layer that connects the distribution layer switches to each other and to other networks, such as enterprise networks or WANs. The core layer provides high-speed switching, routing, resilience, scalability, etc. for the distribution layer.
Enterprise Network Design
Enterprise network design is the process of designing networks that connect the devices and users across multiple locations. Enterprise networks typically use WAN technologies, such as routers, firewalls, VPNs, MPLS, etc. Enterprise networks are usually organized into three layers:
Edge: which is the layer that connects the campus networks to the WANs. The edge layer provides connectivity, security, quality of service, WAN optimization, etc. for the campus networks.
Aggregation: which is the layer that connects the edge layer routers to the core layer routers. The aggregation layer provides aggregation, routing, filtering, redundancy, load balancing, etc. for the edge layer.
Core: which is the layer that connects the aggregation layer routers to each other and to other networks, such as Internet, cloud services, or partner networks. The core layer provides high-speed switching, routing, Branch Network Design
Branch network design is the process of designing networks that connect the devices and users at a remote location. Branch networks typically use a combination of LAN and WAN technologies, such as switches, routers, firewalls, wireless access points, VPNs, etc. Branch networks are usually organized into two layers:
Local: which is the layer that connects the end devices, such as PCs, laptops, phones, printers, etc. to the network. The local layer provides connectivity, security, quality of service, power over Ethernet, etc. for the end devices.
Remote: which is the layer that connects the local layer switches to the enterprise network or the Internet. The remote layer provides connectivity, security, quality of service, WAN optimization, etc. for the local layer.
Expanding Existing Networks
The fourth part of the book covers expanding existing networks, which is the process of designing networks that support new or emerging technologies and trends. Expanding existing networks involves adding new components or capabilities to your network design without compromising its performance or quality. Expanding existing networks also involves adapting your network design to changing business goals and user needs. In this part, you will learn how to design networks that support six main technologies and trends:
Wireless: which is the technology that allows devices and users to connect to the network without wires or cables. Wireless networks use radio waves or infrared signals to transmit data over the air.
Security: which is the technology that protects your network from unauthorized access, misuse, or attack. Security networks use various methods and devices to prevent, detect, and respond to network threats.
Collaboration: which is the technology that enables devices and users to communicate and work together across different locations and platforms. Collaboration networks use various applications and services to support voice, video, data, and web conferencing.
Virtualization: which is the technology that allows you to create multiple virtual instances of devices or resources on a single physical device or resource. Virtualization networks use various techniques and tools to consolidate, abstract, and isolate network functions and services.
Programmability: which is the technology that allows you to automate and customize your network operations and management. Programmability networks use various languages and protocols to control and configure network devices and services.
Data centers: which are the facilities that house and support your network servers, storage devices, applications, and services. Data center networks use various architectures and technologies to optimize performance, availability, scalability, and security of your network resources and services.
