Introduction

Separation logic provides a wider insight in Hoare’s logic perception about programs. Separation logic is based on the manner in which programs can influence the hiding of data in existence of pointers (Zhang, 2005). The separation logic offers modular reasoning during virtual separation and avoidance of semantic axioms.

Network configuration is referred to the process of organizing and maintenance of data and information about all the modules of a computer network (Apgar, 2010). In case a network requires modification, repair, backup or upgrade, system administrators refer to network management databank to choose the best course of action to counter the problem (Chellis, 2008). The databank has all the information about the network addresses and their specific locations and data about the hardware and software versions as well as the already installed updates.

Technological advancement in terms of design is critical in any organization. Developing a comprehensive design helps in reducing technological risks and reducing the cost of network management and deployment (Chellis, 2008). Persons utilizing technologies such as NIL design get the best service from the technological engineers because a special design network is developed that can sustain, troubleshoot large multiprotocol networks. Network design is critical for a number of reasons such as;

Application of design documentation offers clients a proper outline for the implementation of the network with a possibility of long term development and growth. Well-designed network designs should the capacity, proper security and accommodate future growth and efficiency (Zhang, 2005). The duration used to implement the network is limited and at the same time provide a proper background for future upgrades or even overhaul of the network (Apgar, 2010). The setup and structure of the network make it easy to maintain and operate. Logical errors and scaling issues are by a bigger margin eliminated because of enhanced network availability (Apgar, 2010).

Network service providers have a duty to offer their clients with the best service. For better service delivery, network configuration is essential. Network configuration provide a win-win scenario for both the service provider and the customers (Kenyon, 2002). When the service provider automates his IP address and the configuration system, there is improved resource utilization and a further reduction in staffing requirements. An automated IP address assignment results to fewer outages and limits human errors because the system is developed to offer high reliability and consistency.

Network configuration enhances productivity through reducing network configuration tasks through utilizing DNS zone management and IPAM (Apgar, 2010). Blocking of IP addresses uses limited time and in due process the service provider has time to optimize network performance and creation of new services and services are offered in good time (Chellis, 2008).

Network planning and design includes aspects of network synthesis, topological design, network realization as well as topological design. The setup of the scheme is to ensure client’s needs are met by the telecommunications network. The design encompasses a five layer plan that includes a business plan, IT asset sourcing, operations and maintenance, short terms planning and medium and long term network planning (Chellis, 2008). Network planning and design is made up of three major functionalities i.e. topological design, network synthesis and network realization (Chellis, 2008). Network design monitors traffic intensity and load. Traffic measurements are used to estimate the load of a network.

Designing of a network is a tiresome and time involving job and complex. The design of a network consist of three key subnets which include the end user network, server networks and hybrid networks. The VLAN is a network that is segmented and linked to the organization’s functionality, coordination of project teams and even applications despite of the geographical basis. In case of traffic overload, the VLAN allows a systematic topological overlay that switches the physical infrastructure. The system is designed in a manner technological segments separate layers of broadcast and data packets are distributed between ports contained in the same VLAN (Zhang, 2005). Through coordination of traffic that originates from a specific LAN, to other local area networks, (LANs) in the same VLAN.

VLAN is essential in terms of controlling the traffic because the virtual networks reduce wastage of the bandwidth and bridges the switched networks which packets are forwarded to the LANs (Chellis, 2008). Implementation of the system enhances scalability, enhancement of multicast and intensive protocols as well as applying the flood data packets throughout the system’s network (Kenyon, 2002). Security of data is enhanced because VLAN of isolating groups. Controlling of traffic isolates traffic by isolating collision domains and eventually bridging them together.

Conclusion

Designing, placement and configuration of data networks require technically and dedicated personnel. Proper maintained and monitoring the network is critical in ensuring that errors are limited and proper service delivery is achieved. Automated configured and designed systems are key at such age and time because of the manner in which time and cost is saved. VLAN isolates and separates traffic, thereby reducing the load LAN networks can sustain (Kenyon, 2002). The data is distributed within various LANs and an equilibrium achieved in terms of the manner the load is maintained in the LAN network. Coordination of all these factors improve the way clients make the best out of the technological companies and experts.
