Design Issues
The session layer is the thinnest layer with the most negligible numbers of protocols in the OSI model.
The session layer objective is to create, maintain and synchronize dialogs between transmitting upper layers.
Communication can take place between either users or applications..
Computer networks provide services in the form of network resources to the end users.
The main design issue is to allocate and deallocate resources to processes.
The allocation/deallocation should occur so that minimal interference among the hosts occurs and there is optimal usage of the resources.Sep 12, 2023.
Design Issue means any matter arising under, with respect to or in connection with, the Contract Documents, and, in particular, the drawings and specifications, which requires clarification in order to complete the Work..
Network layer design involves key challenges: routing, addressing, and forwarding.
Routing protocols determine paths for data packets, balancing efficiency and reliability.
Addressing assigns unique identifiers to devices.
Forwarding directs packets based on addresses..
Network architecture refers to how computers are organized in a system and how tasks are allocated between these computers.
Two of the most widely used types of network architecture are peer-to-peer and client/server.
Client/server architecture is also called 'tiered' because it uses multiple levels..
Now that we understand the basics of a network lifecycle model, let’s take a step-by-step look at the process of designing a network infrastructure.
While the specifics of your network design will vary based on size and complexity, this general framework can help you make the right decisions.
You need to assess the network’s current state before you make any specific design recommendations.
At the end of this step, you should understand the network layout, performance, data flows, applications & services on the network, network security, and physical and logical layout.
Now that we have a framework to follow, let’s take a look at some network design best practices for making better decisions throughout the process.
Some of the main design issues are as follows − Network channels and components may be unreliable, resulting in loss of bits while data transfer.
So, an important design issue is to make sure that the information transferred is not distorted.
Networks are continuously evolving.
The sizes are continually increasing leading to congestion.
Before we move on to the next step, let’s take a look at two key network design concepts:
So, an important design issue is to make sure that the information transferred is not distorted.
Networks are continuously evolving.
The sizes are continually increasing leading to congestion.
Also, when new technologies are applied to the added components, it may lead to incompatibility issues.
Network design is the practice of planning and designing a communications network.
Network design starts with identifying business and technical requirements and continues until just before the network implementationstage (when you actually do the work to deploy and configure what was designed).
Network design includes things like network analysis,.
