Abstract
A method and apparatus for scheduling reservations of resources in a packet-switched communication network including end-nodes and core network switches are described including a time information to each request, issued by an end-node and forwarded by at least one core network switch, and requesting a resource reservation for receiving a stream defined by specifications at a time which is represented by the time information, the reservation scheduling being handled at a data link layer of an Open Systems Interconnection (OSI) model and storing the time information, included into each forwarded end-node request in correspondence with associated stream specifications, into at least one related database managed by a core network switch participating in the request forwarding.
