After achieving the milestone of 10Gbps of data transfer speed, the service providers have started using interfaces that support 40G and 100G technology. The routers, switches and the transceivers supporting 40Gbps and 100Gbps data transfer rate have already started appearing on the networking plan and the need is to find end solutions that work well at the same power and also support such high-speed networks.
Since high-speed network has become a real thing, the other factors such as traffic tolerance and better compatibility with paired connections are being focused upon. Thus, the experts are not working to develop high-speed networks that:
- support interconnections of varying types;
- display high throughput and reduce delay;
- help avoid congestion;
- respond instantaneously to hardware or link failure;
Basic aims of developing high-speed networks
Inclusion of Small packets
A high-speed network is an advantage over circuit-style network as it keeps in loop the slower machines by way of packet switching and enables multiplexed communication among them; whereas, the latter is effective in handling bulk data transport in an end-to-end set up. The high-speed networks can help accommodating both features in a single network and also utilizes the small packets for meeting the data communication purposes.
Protocol independent network
The biggest premise of inconvenience in a network is the prevalence of protocol specific components. This makes the upgradation or easier replacement processes difficult complicating the lives of networking managers further. With the introduction of high-speed networks, the technology can be made to align with newer protocols and applications. Such networks delivering high speeds are designed to treat the network as a universal system for packet delivery while overlooking the protocols of the integral components. This would bring in more dynamicity in the existing network.
Flexibility in adopting topology
One of the most important aims of adopting high-speed network is to make the networks flexible in terms of adopting topology. Various topology designs are suitable for different networks as one size cannot fit all. Ring and tree are the most common topologies that one can adopt to enable the network meet the communication goals easily. Still, there would be some managers that would have to keep an amoebic structure in mind so that they can modify and improve on topologies in an application-centric way or for integrating redundant elements for achieving omnipresent nature in the network. Generally, the topology should be a good enabler of network study that allows the manager tracking the end-to-end connections and eventually fixing the faults in minimal time. A high-speed network is also used for configuring the speed across the switches participating in end-to-end connections.
An intelligent network designer keeps in mind the inevitability of growth. A high-speed network is designed considering the possibility of growth in mind. The growth is not only about adding more and more machines to the network; but it also should focus on adding more end users per network. Both the conditions bring the situation of high load. Thus, a high-speed network, in order to maintain its longevity, should integrate into the design the scope for more data movement or for handling more loads per machine. Making the existing network more accommodating is anytime cost-effective than building newer networks from the scratch.
Easy Management of Networks
Complex network may look exciting but managing it is truly a nerve-wrecking experience. The faults may go unnoticed as it won’t be possible for the manager to reach the root problem if the structure is too complicated. Since the present day networks are catering to the users from different time-zones, these cannot afford to stay inactive or dysfunctional even for a minute or so. Thus, easy monitoring and automated features of diagnosis are desirable features in a high-speed network. Managers also need to be aware of the global policy of resource allocation so that they can deliver exactly what is expected from the network.
Make use of Cost Effective technology
High speed need not carry hefty price tag with it. Network managers are given the task of finding cost-effective ways to build technologies by recycling the electronic parts or by reusing the portions of existing infrastructure. Inexpensive components can also yield high-speed networks; the only thing that is required is the vision and ability to make the best out of what is considered waste.
How one can achieve these goals
Once the aims of building a high-speed network are clearly established, the next obvious step is to look for the designs that are helpful in achieving these aims. As an expert, the network specialist can set the design criteria; some of the important criteria supporting these aims are:
- Adopting designs that avoid congestion and offer better control: Introduction of external nodes that enable faster understanding of network status and quicker transfer of data packets is a possible solution for high traffic network.
- Proactive approach for failure recovery: The network manager needs to have alternate routes readily available to provide cover-up for the faulty links.
- Electronic switches promoting high speed: Introducing electronic switches enabling multiple fiber lines at speed of 100 Mbps per line can also offer better speed as well as easy manageability.
Thus, to switch to high-speed networks, the managers need immaculate planning as well as adopting correct design. Setting correct aims and adopting suitable methodology are the right ways which the main league service providers seem to have mastered; they also have set the benchmarks for the other players.
