Updating networks to meet today’s business and security requirements

Networks are the key to outstanding IT and business performance

State-of-the-art networks improve IT and business performance

Outdated technology can impede the operation of high-performance networks – and leave them vulnerable to cyber-attacks. Reengineering the network from the ground up minimizes security risks, enables the implementation of quality of service, and enhances performance.

Local area networks (LAN) and wide area networks (WAN)

According to the EMC Digital Universe study, the volume of data is produced annually worldwide will rocket to a remarkable 44 trillion gigabytes – that is 44,000,000,000 gigabytes – by 2020. This would represent a ten-fold growth in data volumes compared to 2014. The study attributes this rapid rise to the Internet of Things and the “emergence of wireless technologies, smart products and software-defined businesses”. Moreover, by 2020, EMC expects that 40 percent of data will be ‘touched’ by the cloud.

Performance and quality

T-Systems draws on many years’ experience and expertise in the field of networks and network design. When it comes to networks, data volume is not the only factor to consider; overall performance – in other words, the quality of data transmission – is also critical, particularly for applications requiring real-time communications, such as M2M, telephony and videoconferencing.

Digital business models

Against this background, future-proof networks are increasingly fundamental to ensuring the success of digital business models. Without re-engineering local area networks (LAN) and wide area networks (WAN), business digitization becomes almost impossible. Many network managers have recognized the urgent need to update their increasingly outmoded networks, and often attempt to meet the new imperatives with their familiar manual administration methods. This is a difficult task, as much outdated network hardware and software is still in use, since their innovation cycles are far longer and slower than those for server technologies and applications. There is a particular need to upgrade the technology used for mobile network solutions – with many WLAN access points dating back to the early days of mobile LAN.
Future-proof networks
Frank Westermann, VP Marketing TC Division:
Network service integrators make sure that cloud-based applications can be used on any device – transparent and secure. 
With this in mind, decision-makers must address a number of business-driven issues regarding their networks. How can IT provide applications worldwide to high quality standards? How can IT effectively support employees with their everyday business tasks? How quickly can new sites be integrated into the corporate IT infrastructure? And how can network specialists keep costs under control?

Proactive network monitoring

The effects of outdated networks are clear – from high latency to erratic data transfer rates. They simply cannot meet the needs of time-critical applications such as VoIP communications or database access by ERP systems. Quality of service (QoS) and prioritizing data streams through service classes (CoS) can resolve these issues and ensure reliable, high-performance data transmission across long distances. Key methods include the early identification of looming bandwidth bottlenecks, proactive monitoring of network and application infrastructure, and application optimization. 
Outdated networks also pose security risks. State-of-the-art technology is the only way to combat the huge rise in professional cybercrime. IDC estimates that 40 percent of all data requires protection, but only 20 percent of the data is actually protected.
