摘要:
The invention relates to the field of network communication in a wide area, where a local network of a first type (20) has a sending station (21) that communicates with a receiving station (31) in a local network of a second type (30). A network of a third type (50) is in between the two networks (20, 30) and provides virtual private networking between the two local networks (20, 30). The network of the first type (20) supports a fine grained QoS, whereas the network of the third type (50) supports a coarser grained QoS. In one example the network of the first type is RSVP capable and the network of the second type is an MPLS network. The invention resides in a component called RSVP-MPLS proxy (100) that maps the RSVP resource advertisements and reservations within an RSVP-aware customer network to an MPLS network, whereby the receiver side doesn't participate in the RSVP communication process.

Real time streaming over serial buses (20) using Internet protocol IP is becoming more and more important. With new bus technologies e.g. 10Gbit Ethernet even streaming in HD cinematography quality and uncompressed form becomes possible. In this case, however, data access management by software means is critical or simply not possible for performance reasons even if high performance microcontrollers are used where the software runs. The invention proposes for an apparatus in a network to implement hardware means (26, 27, 28) for processing the real-time critical data packets as well as software means for processing the real-time uncritical data packets and a filter algorithm respectively a de-multiplexer (25) for analyzing packet header and passing the real-time critical data packets to the hardware means (26, 27, 28) and the real-time uncritical data packets to the software means.
