Abstract: A composite buffer architecture for forming a III-V device layer on a silicon substrate and the method of manufacture is described. Embodiments of the present invention enable III-V InSb device layers with defect densities below 1×108 cm?2 to be formed on silicon substrates. In an embodiment of the present invention, a dual buffer layer is positioned between a III-V device layer and a silicon substrate to glide dislocations and provide electrical isolation. In an embodiment of the present invention, the material of each buffer layer is selected on the basis of lattice constant, band gap, and melting point to prevent many lattice defects from propagating out of the buffer into the III-V device layer. In a specific embodiment, a GaSb/AlSb buffer is utilized to form an InSb-based quantum well transistor on a silicon substrate.

Abstract: A flexible, policy-based, mechanism for managing, monitoring, and prioritizing traffic within a network and allocating bandwidth to achieve true quality of service (QoS) is provided. According to one aspect of the present invention, a method is provided for managing bandwidth allocation in a network that employs a non-deterministic access protocol, such as an Ethernet network. A packet forwarding device receives information indicative of a set of traffic groups, such as: a MAC address, or IEEE 802.1p priority indicator or 802.1Q frame tag, if the QoS policy is based upon individual station applications; or a physical port if the QoS policy is based purely upon topology. The packet forwarding device additionally receives bandwidth parameters corresponding to the traffic groups.

Abstract: A method of manipulating one of a plurality of branches of a menu structure within a window of a menu editor in a graphical user interface is described. A handle associated with a first branch of the plurality of branches is provided. The first branch is associated with a first menu item of the menu structure. The handle is selected. The first branch is moved in response to a cursor control device to associate the first branch with a second menu item of the menu structure. The first branch is disassociated with the first menu item. The first branch is associated with the second menu item of the menu structure.
