A time slot management method for use in a time division multiple access system that couples a line terminator via a tree-like network to a plurality of network terminations is provided. At least one grant is transmitted by the line terminator towards a network terminator in order to allocate at least one adjacent subsequent corresponding upstream time-slot to the network terminator. The grant is received by the network terminator from the line terminator, and it is recognized if the at least one grant is associated with the network termination. Upon recognition of the at least one grant being associated with the network termination by the network terminator, overhead data in the first time slot of the at least one time slot and payload data in each potential adjacent subsequent time slot of at least one time-slot allocated to said network terminator is transmitted.

The present invention is related to a method to control and to change dynamically a MAC address in an aggregation network containing at least a server computer device and a client device, comprising the steps of:

Dynamic change of MAC address

Network devices () receiving first packets from first devices () and in response transmitting second packets to second devices (), and receiving third packets from the second devices () and in response transmitting fourth packets to the first devices (), get manipulation means () for manipulating information at layers higher than internet protocol layers of headers of packets for improving transport efficiencies between the first and second devices (). The higher layer may comprise a transport control protocol layer-4 to allow the network devices () to take over acknowledging functions of the second devices () and to take over re-transmission functions of the first devices () and to support the second devices () through offering additional buffer space and to support the first devices () through offering extended/advanced stream management.

In methods for setting up communications between digital-subscriber-line terminal modems () and internet-service-providers () via digital-subscriber-line-access-multiplexers () and forwarders () of asynchronous-transfer-mode-networks () further comprising dynamic-host-configuration-protocol-relay-agents (), first messages are sent from the terminal modems () to the agents () via the access multiplexers (), which first messages comprise incoming logical identifiers defining couplings () between the terminal modems () and the access multiplexers (), second messages are sent from the agents () to dynamic-host-configuration-protocol-servers () for receiving internet-protocol-addresses to be supplied to the terminal modems () via the agents (). To be able to locate the agents () outside the forwarders (), the agents () convert the first messages into the second messages at least by inserting outgoing logical identifiers defining couplings () between the access multiplexers () and the forwarders (), and the forwarders () are informed about relationships between the Internet-Protocol-addresses and the outgoing logical identifiers. The forwarders () then have sufficient knowlegde to find the right (part of the) access multiplexer ().

The present invention is related to a method to forward an Ethernet packet in an Ethernet based access network. It comprises the step of receiving the Ethernet packet at a network access node being part of the access network and further the step of transforming at the network access node a first Ethernet MAC address contained in the Ethernet packet into a second Ethernet MAC address. Either the first or the second Ethernet MAC address comprises subscriber or subscriber line identification. Subsequently the step of continuing the communication protocol is performed.

Architecture for bridged Ethernet residential access networks

A method for control of communications from an edge device of an access network, via the provisioning or the non-provisioning of at least one layer 2 destination address of at least one other edge device of the access network to the edge device by a network management module of the access network. The at least one layer 2 destination address is delivered to the edge device on request of the edge device. In an exemplary embodiment, the edge device checks, upon arrival of a packet including at least one layer 2 destination address, whether the at least one layer 2 destination address is stored within a communications restriction filter of the edge device and generates the request including the at least one layer 2 destination address in case the at least one layer 2 destination address is not stored within the communication restriction filter.

A point-to-multipoint telecommunication system can be made more flexible by providing upstream units with generators and locators for generating at least two subsequent overhead cells located next to each other and neighbouring a larger number of data cells for supplying system information. Downstream units are provided with detectors for detecting the subsequent overhead cells. This new signal flame structure allows a larger number of data cells to be exchanged without being interrupted by an overhead cell. Each cell consists of at least 53 bytes in accordance with the Asynchronous Transfer Mode or ATM standard. The at least two overhead cells comprise two overhead cells for supporting 54 data cells, or comprise three overhead cells for supporting 103 data cells. The point-to-multipoint telecommunication systems comprise passive optical networks, with upstream units corresponding to line terminators, and with downstream units corresponding to network terminators.
