The network architecture is a combination of technological acts into a composite environment of highly available, secure, climbable, manageable, and reliable services. The architecture sheltered network devices operate at the various layers of the Open Systems Interconnect (OSI) model. In computing, network architecture is considered as the design of computer networks whereas in telecommunication, it describes the design principles, physical configuration, functional organization, operational procedures, and data formats used for the construction and operation of a communication network.
The business level network architecture comprises the Local Area Network (LAN) segments, Wide Area Network (WAN) segments, LAN and WAN connectivity devices, network protocols, and enterprise security policy. The advantages of network architecture are to provide a reliable and efficient repositioning of data packets from a source device to a target device and obey the organizational security policy. It is vital for the network designer to acquire the following information from the security administrator and administrators of each rank within the organization before plunging into a network architecture design.
Security zone definitions: It is very much essential to understand the concept of hosting a member of a particular tier and security zone. A tier is defined as a reasonable thing, composed of one or more hosts or devices that provide similar functionality; a security zone is a logical existent circumscribing one or more tiers. A zone can contain other security zones, be a member of other security zones, or extend across other security zones.
Security zone restrictions data: This involves the standards or protocols that are authorized to reposition between the zones that have been specified for the organization. This information can be collected from the security administrator of an organization.
Required tier communications data: It is the information in detail about the tiers that are needed to communicate with each other. This information can be gathered from the administrators of each of the tiers in the organization.
Required host communication performance and availability data: This depicts the information about the acceptable hidden levels, availability requirements, and bandwidths needed between each of the source and destination hosts. This information must be gathered into a worksheet from the administrators of each of the tiers in the organization.
The term network architecture has also come to symbolize classifications and implementations of distributed computing architectures. For example the applications architecture of the telephone network Public Switched Telephone Network (PSTN) has been termed as the Advanced Intelligent Network. There are numerous specific classifications lying on a connected series between the dumb network (e.g. Internet) and the intelligent computer network (e.g. the telephone network PSTN). Other networks contain various elements of these two classical types to make them suitable for various types of applications.
