Abstract: A method for routing data over a telecommunications carrier network including at least two switching devices defining at least one physical link, the method including defining in advance a plurality of traffic flows, each associated with specific routing through at least one of the physical links in the network; configuring a routing system according to the traffic flows; collecting data of traffic transmitted over at least some of the traffic flows, calculating traffic statistics, from the collected data, for each of the flows in the network; and re-calculating the routing system configuration utilizing the calculated traffic statistics.

Abstract: A method and system for controlling admission of data traffic to a telecommunications network having an allocatable bandwidth, at least one physical link and at least two pre-defined flows over the link, the method including receiving input data of each of the at least one physical links in the network, the data including for each of the links a wire rate bandwidth, a provisioned committed bandwidth, and a provisioned best effort bandwidth; calculating a bandwidth available for best effort from the wire rate bandwidth and the provisioned committed bandwidth; and allocating the bandwidth available for best effort between the flows substantially proportionally to the provisioned best effort bandwidth.

Abstract: A configurable edge device for use in a network, the edge device being adapted and configured to be coupled to at least one other edge device in a network, and including an admission controller for controlling admission of data traffic onto a pre-defined flow over a physical link, and a router for routing the data traffic through the edge device onto the pre-defined flow in accordance with a pre-defined routing scheme, wherein operation of the admission controller and the router is controlled in accordance with data defining all physical and logical links in the network; a telecommunications carrier network for data traffic, the network including at least two such configurable edge devices, and a method for transmitting data traffic through such an edge device.

Abstract: A method for relaying Ethernet frames over an Ethernet network, the method including adding a tag that provides an address from a hierarchical address scheme to an Ethernet frame; and relaying the Ethernet frame through the network according to the tag. There is also provided a configurable Ethernet bridge having a filtering database including a plurality of subnet masks for relaying frames according to a hierarchical address scheme.
