New Challenges
To build up future proofed networks it is absolutely essential to have a fundamental knowledge of network technologies and current trends. In the last years more and more classical applications which have nothing to do with TCP/IP have been migrated to Ethernet and IP.
Applications such as Voice/Video over IP require new performance features like Quality of Service. High availability of hardware, redundancy of WAN connection and dynamic bandwidth reservation in combination with smart routing protocols as well as security needs reflect the challenges of modern networks. Virtual private Networks (VPNs) are an essential part of company networks and are applied to grant access for mobile/home office users.
Recent technology trends such as cloud computing, mobile applications, tablet PCs, social media are changing the security and availability needs of company networks. This is one of the biggest challenge company networks are facing.
