Abstract: A luminaire with a heat sink (1), which heat sink is formed by one integral piece of cold forged aluminum, comprising an essentially flat base portion (2), having a base surface with a center (2a) and an outer periphery (2b) and a set of heat dissipating fins (3, 4) extending from a first side of the base surface, in a direction normal to the base surface. The set includes at least one radial heat dissipating fin (3) having a cross section in a plane parallel to the base surface which cross section extends substantially in a radial direction from the center (2a) towards the outer periphery (2b), and at least one peripheral heat dissipating fin (4) having a cross section in a plane parallel to the base surface which cross section includes a portion extending in a direction parallel to the outer periphery (2b), wherein the peripheral heat dissipating fins (4) are arranged radially outside the radial heat dissipating fins (3).

Abstract: An electrical control device is described.

Abstract: Multi-Protocol Label Switched (MPLS) traffic is re-routed to an alternate, Label Switched Path (LSP) to bypass a failure along a primary LSP, even though the failure occurs at or along an ingress section of an LSP, while associating an original IP address to the alternate path. Failures are also detected farther downstream outside an ingress section. When this occurs, MPLS traffic is re-routed to an alternate LSP which maintains the same quality of service as an original primary path and includes other network devices which are not a part of the primary path (except for the network device and a destination network device). The techniques require less resources than existing techniques.

Abstract: Bi-directional Label Switched Paths (LSP) are created by bundling a forward and backward LSP. The forward LSP is separately generated from the backward LSP. The so-created, bi-directional LSP can be deleted when delete path requests are generated and received by both the forward and backward LSPs, respectively.

Abstract: In Switches, switch inputs and outputs may be grouped into (e.g., small) modules called input shared blocks (or “ISBs”) and output shared blocks (or “OSBs”), respectively. Each of the switches includes three (3) main parts: (i) input shared blocks (ISBs); (ii) a central switch fabric (or “ATMCSF”); and (iii) output shared blocks (OSBs). Input link sharing at every ISB-ATMCSF interface and output link sharing at every ATMCSF-OSB interface cooperate intelligently to resolve output contention and essentially eliminate any speedup requirement in central switch fabric. Each of the proposed switches can easily scale to a large size by cascading additional input and output shared blocks (ISBs and OSBs). Instead of using a centralized scheduler to resolve input and output contention, the each of the switches applies a distributed link reservation scheme upon which cell scheduling is based.
