Abstract: An illuminated road sign, that includes: a supporting element, a front element, and multiple electroluminescent lamps located between the supporting element and the front element; wherein the front element comprises multiple regions, wherein at least one region is defined by a translucent reflecting element; wherein the electroluminescent lamps are shaped and placed according to the multiple regions; wherein the electroluminescent lamps are adapted to blink, during at least one blinking period.

Abstract: Techniques for configuring a network to support real-time applications include maintaining multiple templates and a meta-template. Maintaining each template includes associating a class of network elements with an action to perform on a network data packet by a network element that belongs to the class. The class is defined by a first constraint set on one or more first properties of the network elements. Maintaining the meta-template includes associating external information with an associated template. The external information indicates a second constraint set on one or more second properties different from the one or more first properties. The network elements are automatically configured based at least in part on the meta-template. These techniques allow two members of the same class to be automatically configured for different QoS policies based on such external information as a property of a peer device or data rate on a connected link.

Abstract: Techniques for configuring a network to support real-time applications include determining a first role of multiple of roles performed by network elements to completely support a particular real-time application. Each role is associated with multiple groups of policies. Each group of policies includes one or more policies associated with a class of network elements. The network includes multiple classes. Each policy includes a configuration command that causes a network element of an associated class to perform an action on a data packet to support an associated role. A first subset of network elements is selected from the network. The first subset includes network elements that perform the first role. The selection is based at least in part on network links in the network. Each network element in the first subset is associated with a group associated with the first role.
