A method for managing bandwidth and managing storage resources within a single session of a resource reservation protocol being a RSVP, Resource Reservation Protocol, protocol in a transport network having nodes that include a processor and data memory means that may be assigned to temporarily caching data at said node or to longer term storage allowing applications and data to be stored therein comprising a step of allocating a determined volume of said memory means to storage resources in which applications and data may be stored, comprising: at a first node of said network, receiving a request to allocate a defined storage volume at a second node of said network, and a request to provide a specified bandwidth from said first node up to said second node where said storage resources are to be defined, encoding said request to provide the specified bandwidth as information in a resource reservation protocol message and inserting said request to allocate a defined storage volume at said second node of said network as a STORAGE_REQUEST object in said resource reservation protocol message, transmitting said message through said network along a path to said second node, reserving said specified bandwidth at each intermediate node of said network, at said second node, receiving said resource reservation protocol message, and parsing its content in order to request reservation of said specified bandwidth at said second node of said network and determining whether said bandwidth allocation request can be satisfied, and parsing the content of said STORAGE REQUEST object contained in said resource reservation protocol message, in a storage management unit of said second node, determining whether said storage allocation request in said STORAGE_REQUEST object can be satisfied, if said bandwidth allocation request and said storage allocation request can be satisfied at said second node, the step of sending a successfully reserved storage space identifier in the form of a STORAGE_SPACE object constituting a part of a message of said resource reservation protocol back from said second node to said first node, along the path that was followed by the resource reservation protocol message through said network from said first node to said second node. at a first node of said network, receiving a request to allocate a defined storage volume at a second node of said network, and a request to provide a specified bandwidth from said first node up to said second node where said storage resources are to be defined, encoding said request to provide the specified bandwidth as information in a resource reservation protocol message and inserting said request to allocate a defined storage volume at said second node of said network as a STORAGE_REQUEST object in said resource reservation protocol message, transmitting said message through said network along a path to said second node, reserving said specified bandwidth at each intermediate node of said network, at said second node, receiving said resource reservation protocol message, and parsing its content in order to request reservation of said specified bandwidth at said second node of said network and determining whether said bandwidth allocation request can be satisfied, and parsing the content of said STORAGE REQUEST object contained in said resource reservation protocol message, in a storage management unit of said second node, determining whether said storage allocation request in said STORAGE_REQUEST object can be satisfied, if said bandwidth allocation request and said storage allocation request can be satisfied at said second node, the step of sending a successfully reserved storage space identifier in the form of a STORAGE_SPACE object constituting a part of a message of said resource reservation protocol back from said second node to said first node, along the path that was followed by the resource reservation protocol message through said network from said first node to said second node.
