| 5 | | ariba provides what services and applications seek: ''seamless connectivity that "just works"''. Providing this connectivity introduces increasing challenges, e.g., wireless network access, mobility, heterogenity, and, middle-boxes (e.g., firewalls, or NAT gateways) impede end-to-end communication and, therefore, the development of new services and applications. Each of those challenges has its tailored solution. However, most of the solutions need dedicated support by the infrastructure, require manual configuration and do not adapt to changing network conditions. Furthermore, they often do not run across heterogeneous networks (e.g., pure IPv4, IPv6, or different networks behind NAT-gateways). |
