摘要： A system for scheduling utilization of a service resource by a plurality of flows of information packets, wherein the flows include rate-guaranteed synchronous flows and best-effort asynchronous flows, the asynchronous flows exploiting the service capacity of the resource left unexploited by the synchronous flows. A server visits the flows, in subsequent rounds, by visiting first the synchronous flows followed by the asynchronous flows. The server is configured for detecting any backlogged synchronous flow, and when the server visits any said backlogged synchronous flow, it allows the backlogged synchronous flow to utilize the resource for a given time, whereby the synchronous flows have a guaranteed transmission window on each round. When the server visits any asynchronous flow, the time elapsed since the last visit by the server to the same asynchronous flow is determined. If the visit to the asynchronous flow occurs later than expected based on a reference round time, the asynchronous flow being visited is restrained from utilizing the resource for the ongoing round, and if the visit occurs earlier than expected based on the reference round time the asynchronous flow being visited is allowed to utilize the resource for a respective given time.

摘要： A method and system for performing admission control in a packet-based telecommunication network includes a backbone network coupled between at least two access networks. When a first user on a first access network wants to communicate with a second user located on a different access network, a request is made to a quality server whether network resources are available. The quality server separately monitors both access networks and the backbone network and determines whether network resources are available to satisfy the request. In one embodiment, a two-tier approach is used wherein a coordinator module interacts with an admission control subsystem including a plurality of subsystem modules. Each admission control subsystem module is responsible for monitoring a part of the network, such as, one access network or a backbone network. The coordinator module determines which subsystem modules are associated with the user request and interrogates such subsystem modules as to resource availability.

摘要： A system for providing, to users of data communication services, access to a communication network providing these services includes an edge node as well as a packet network, such as an Ethernet connecting the users to the edge node. The packet network is equipped with operation and maintenance procedures for preserving edge connectivity over the packet network. The edge node is associated with a backup edge node, which also provides access to the communication network. Preferably, the backup edge node has the same address as the edge node such that, in the presence of failure of the edge node, seamless connection is established between the users and the backup edge node by applying the operation and maintenance procedures.

摘要： A system for the time-based accounting of access by users to services provided by a data network includes a primary access node to provide access by users by establishing via the primary access node a steady connectivity between the users and the network. A secondary access node is associated with the primary access node, such secondary access node being configured for acting as a backup node to maintain connectivity in the case of failure involving the primary access node. The primary access node is configured for issuing a request for credentials for any user requesting access to said data network and, as a result of receiving valid credentials from the user, starts time-based accounting for the user. An authentication node cooperative with the primary access node and the secondary access node stores the secondary access node information items concerning the time-based accounting started for the user. The time-based accounting is thus maintained in the case of failure involving the primary access node as connectivity is maintained by the secondary access node.

摘要： A basic element for the interconnection network of a fast packet switching node, where a synchronization is made at bit input stream level, the cell beginning is identified and a stream conversion from the serial form to a word parallel form is performed. Cells are thus transformed in a completely parallel form and in the same form they are cyclically discharged in the subsequent cell time in a memory, where cells are written and read in a shared way on the basis of instructions given by a control unit, thus performing the switching function. The control unit is essentially based on the use of a content-addressed associative memory, where a fraction of the routing header and a code indicating the time sequence on which the cells are stored. Memory outgoing cells are reconverted from a completely parallel form to a form having the length of one word and therefore in a completely serial form at a bitrate equal to the input one.

摘要： A method of providing access of a mobile terminal to an IP network includes establishing a security association between the mobile terminal and a first security gateway of a first router in said plurality of routers. The mobile terminal is provided access to the IP network via the first router, and the data exchanged between the mobile terminal and the first router is encapsulated by using the security association. The security association is made available to at least one second router having a second security gateway. The mobile terminal is provided access to the IP network via said the second router, and data exchanged between the mobile terminal and the second router is encapsulated by using the same security association. Establishing the security association includes assigning a Security Parameter Index that identifies univocally the first security gateway and the security association. Making the security association available to the second router includes making available to the second router the Security Parameter Index. The second router may thus have access to the security association either by requesting it from the first router or by identifying it in a set of security associations sent from the first router to a set of routers candidate to become the second router as result of the mobility of the mobile terminal.
