Da CaPo - Dynamic Configuration of Protocols
The goal of protocol configuration in Da CaPo is to create for each connection request at runtime a protocol that fulfills the Quality of Service requirements of the application and is as light as possible. These procols are based on top of high-speed networks (e.g., ATM), traditional local area networks (e.g., 10 Mbit/s ethernet) or wide area network services (e.g., IP, ST-II, or RSVP) and provide a service with the requested QoS directly to the application (see Figure 1). In other words, Da CaPo covers multiple layers of the OSI reference model.

Current Da CaPo activities at UNIK include:
- Re-implementation of Da CaPo on Chorus and real-time scheduling support for Da CaPo protocols.
- Flexible multicast protocols and support of multicast groups with heterogenous requirements.
- Combinding of data managenemt mechanisms in and protocol mechanisms.
- QoS management for real end-to-end QoS, i.e., from human-computer interface (HCI) to HCI respectively to application process. This includes QoS negotiation and resopurce management for operating systems, networks, Da CaPo protocols, data management systems (ranging from simple file systems to complex database systems, applications, and HCI.
