Network Planning and Design

Diversity of network elements and hierarchies, diversity of services and options for carrying them, diversity of embedded bases, and multiple business imperatives make the network planning and design function interesting and challenging.

Decisions on technologies, interconnections of various technologies and protocols, relationships between service mix and networking technologies, topologies, and introduction timing play the major role in network planning function.

Given a composite traffic, and its spatial and temporal characteristics, the big challenges in network planning and design are dealing with the network topology design, identifying the network architecture, and the key characteristics of network elements in terms of both their key capabilities/constraints and the cost structure.

A number of chief issues involved in network planning are:
  •  Traffic planning
  •  Topology planning
  •  Technology planning
  •  Characterizing networking technologies (their capabilities, cost structure, etc)
  •  Capacity planning
  •  Near-term deployment phase
  •  Medium-term deployment phase
  •  Long-term deployment phase

The objective of network design is to minimize the overall network cost while meeting customers’ network performance objectives. The design should specify the selection of topology (location of major access, service and transport nodes and interconnections among them), the network architectures, the key characteristics of network elements in terms of their both capabilities/constraints and cost structure, routing strategies, and capacity allocation.

A good network design is of immense value to Network and Service Providers since they are interested in obtaining the lowest-business cost network designs to keep their operating expenditures (OPEX) and capital cost (CAPEX) as low as possible. Network design helps in this regard by optimizing the access and transport cost. It is the transport cost, which is a significant recurring part of the cost of providing access services.

A versatile network design which can accommodate multiple interface technologies, multiple infrastructure technologies, and multiple tariff structures (domestic and foreign) will be of great value for the Network Providers and Operators.

There are two main categories of network design scenarios:

  •  green field design (for new entrant on the market)
  •  growth design.

Designing a new network from ground zero is considered a green field design. Adding capacities to accommodate growth on an existing network design is design for growth. The need for network growth occurs in response to a number of different causes, such as geographic movement of end users, an increase in the number of end-users or an increased bandwidth requirement.

Telecom Network Providers design mainly an optical fiber or radio based infrastructure. The infrastructure consists of three components. The first component is the access network. The second component of infrastructure includes service nodes providing various circuit-, packet–, and cell-based services using switches, cross-connects, routers, gateways, and so on. The third is the core/backbone transport network. It includes SDH, WDM, and so on.

So, at a high level, the design of Telecom Network consists of three components: an access network design (AND), a service layer mesh network design (SND), and a physical layer ring or mesh network design (PND):

  •  AND
  •  SND
  •  PND

Here, first we state the (long-term) network design principles and define a set of generic network elements. Next, we present a systematic approach for the design of Telecom Network and proceed with the functional design procedure for AND, SND, and PND.
