Networking is the backbone to any organisation’s connectivity, Unitec have vast experience in enterprise class network design, deployment and maintenance that not only addresses the the core function of connectivity but also by design our methodology addresses unavoidable network security concerns. Of course, network designs vary depending on the size and requirements of the organisation, the networking infrastructure needs of a small organisation for example, with fewer devices will obviously be less complex than the infrastructure of a large organisation with a significant number of devices and connections. Regardless of network size or requirements, a critical factor for the successful implementation of any network design is to follow good structured engineering principles,
Hierarchy A hierarchical network model is a useful high-level tool for designing a reliable network infrastructure. It breaks the complex problem of network design into smaller and more manageable areas.
Modularity By separating the various functions that exist on a network into modules, the network is easier to design. Best practises identify several modules, including the enterprise campus, services block, data centre, and Internet edge.
Resiliency The network must remain available for use under both normal and abnormal conditions. Normal conditions include normal or expected traffic flows and traffic patterns, as well as scheduled events such as maintenance windows. Abnormal conditions include hardware or software failures, extreme traffic loads, unusual traffic patterns, denial-of-service (DoS) events – whether intentional or unintentional – and other unplanned events.
Flexibility The ability to modify portions of the network, add new services, or increase capacity without going through a major forklift upgrade (i.e. replacing major hardware devices).
To meet these fundamental design goals, a network must be built on a hierarchical network architecture that allows for both flexibility and scalability. Unitec are leading Cisco and Fortinet partners underpinning our consultants and network engineering capability having implemented large scale LAN and WAN solutions to clients ranging from SMEs, Corporate and Government deployments.
