20080294755 | Method and Arrangement in an Access System - An access node connected to end-users, routers, and a DHCP-server. The end-user defines desired services provided via the routers. A purpose is to automatically provide simultaneous access to services via two or more of the routers, although the end-user simultaneously handles only one router. The connections are secure. The end-user requests one of the services. The access node identifies the end-user and sends a corresponding request to the DHCP-server, which dynamically allocates addresses to the end-user and to all the routers for the desired services. The access node snoops the addresses in a DHCP option message from the DHCP-server, resolves the router addresses, stores IP router addresses and IP MAC addresses in a memory and sets MAC addresses in MAC filters. An option reply with one router is sent to the end-user, which after request for one service, reaches all the services stored in the memory. | 11-27-2008 |
20090238200 | Method and Arrangement Relating to Admission Control of Broadband Services - A broadband access node and method for controlling access by end users to services over communication channels.

20120230346 | Ethernet Switching - A scheduler in an Ethernet switch and method for scheduling and queuing received unicast packets. The scheduler determines a destination address and a traffic priority of a received packet, and searches for a stored association between the destination address and an interfacing port of the Ethernet switch. When a stored association is found, the received packet is scheduled and queued in one of the priority buffers of the output buffer in an associated interfacing port according to the received packet's traffic priority. When no association is found, the scheduler floods the received unicast packet in a flooding buffer in every interfacing outgoing port of the Ethernet switch. The flooded packet may be scheduled as low priority traffic, or may be prioritized in relation to other flooded unicast packets based on each flooded unicast packet's traffic priority. | 09-13-2012 |

20130315257 | ENERGY EFFICIENT ROUTING AND SWITCHING - This invention relates to a method and a node for energy efficient routing and switching in a communication network. When determining the best path from an originating node to a destination node, current routing or switching protocols use route selection metrics based on the bandwidth of the link interface. Certain paths are however consuming more power that others which can result in traffic flowing over a high power consuming and long distance path, because this is the best path based on the existing metrics. The present invention overcomes this by introducing a node and a method to switch data also using energy consumption metrics. These metrics can be based on the power consumption in link interfaces, the links and in the node. | 11-28-2013 |
