Ariba Features

Ariba eases development and rapid prototyping of overlay-based services and applications. To this end, it provides mechanisms for creation and maintenance of overlay links across heterogeneous networks. Furthermore, it supports simulation and of Ariba-based services and applications without changing the code. The main features of Ariba include:

• Node indentificators: Ariba provides a naming mechanism that uses consistent identificators instead of locators for specifying the target of a link.

• Requirement driven protocol selection: Ariba allows for specifying QoS- and security requirements for each link. Based on the requirements, Ariba transparently selects appropriate transport protocols (e.g., TCP, UDP) and security mechanisms (e.g., TLS, IPSec).

• Support for heterogeneity on layer 3: Ariba transparently establish connections between different layer 3 technologies (e.g., IPv4 and IPv6) and to private address spaces (e.g., due to NAT).

• Mobility: In case of locator changes due to handovers, Ariba will transparently reestablish connectivity without affecting services and applications.

• Multihoming: In case of multihomed nodes, Ariba transparently selects appropriate locators for link establishment and selects alternative locators in case of locator failures.

• Simulation support: Ariba-based applications can be evaluated using the ​Omnet++ Discrete Event Simulation System without changing the code.
