The method also includes generating, in each mesh controller, a corresponding link state table based on the passed connection information from each corresponding connected mesh access point. The method also includes generating in at least one of the mesh controllers a mesh table, identifying all of the connecting links for the mesh access points connected among the mesh controllers, based on the mesh controllers sharing the respective link state tables.
US08155003B2 Aggregate policing applying max-min fairness for each data source based on probabilistic filtering
In one embodiment, a method comprises calculating a corresponding data packet arrival rate for each of a plurality of data sources supplying data packets destined for a prescribed destination, the prescribed destination within a machine and the prescribed destination having a bandwidth capacity; calculating a guaranteed shared bandwidth rate for each data source based on assigning a corresponding selected portion of the bandwidth capacity relative to the corresponding data packet arrival rate; selectively passing each data packet from the corresponding data source as a passed data packet, or dropping the corresponding data packet, according to a calculated probability that the corresponding data packet arrival rate does not exceed the corresponding guaranteed shared bandwidth rate; and selectively filtering the supply of aggregated passed data packets, aggregated only from among the passed data packets supplied by the data sources, to the prescribed destination according to the bandwidth capacity of the prescribed destination.
US08154999B2 Packet forwarding apparatus with function of limiting the number of user terminals to be connected to ISP
A packet forwarding apparatus for connecting a plurality of user terminals to an ISP management server has a management table indicating the relationship between a connection port identifier and specific header information in association with the MAC address of each of the user terminals so that, in a communication protocol procedure executed between each of the user terminals and the ISP management server prior to communication with a wide-area network, the packet forwarding apparatus discards a packet for the user terminal when it is determined that the specific header information cannot be assigned to the user terminal based on the management table.
US08154998B2 Method and apparatus for resizing a trunk in a network
A method and apparatus for resizing a trunk in a network are disclosed. For example, the method sets one or more target utilization levels for one or more trunks, and gathers trunk load data from one or more switches in the network in accordance with a pre-determined time period. The method evaluates the trunk load data in accordance with one or more trigger points for resizing the one or more trunks, wherein the one or more trigger points is based on the one or more target utilization levels. The method then resizes the one or more trunks if the one or more trigger points are reached or exceeded.
US08154992B2 System and method for graceful restart
A system for maintaining routing capabilities in a router having a failed control plane provides an active control plane in the router in communication with at least one external node, the active control plane running at least one routing process. A backup control plane may be interconnected with the active control plane, so that the active control plane may periodically transmit synchronization signals to the backup control plane. The backup control plane may update its state based on these synchronization signals. Moreover, the backup control plane may be programmed to take over the routing process of the active control plane if the active control plane fails.
US08154981B2 Record medium, its manufacturing method, mother disc for record medium, and its manufacturing method
Binary information previously recorded in an innermost rim side area is enabled to be stably reproduced. A record medium is formed by sequentially laminating a first information layer 2, an intermediate layer 3, a second information layer 4, and a cover layer 5 onto a substrate 1. First grooves are previously formed in the innermost rim area of the substrate 1. Second grooves are previously formed in an area where data is recorded. The first grooves are set to be shallower and narrower than the second grooves. Thus, such a situation that a BCA signal is modulated by diffraction due to the grooves can be reduced.
US08154979B2 Objective lens and optical pickup apparatus
Disclosed is an objective lens used for an optical pickup apparatus to perform writing and/or reading of an optical information recording medium, comprising an antireflective film on a surface of a light source side, wherein a light flux of wavelengths including a wavelength λ1 of 380 nm≦λ1≦420 nm and a wavelength λ2 of 630 nm≦λ2≦810 nm, is condensed on the medium, a numerical aperture on the light source side with respect to the wavelength λ1 is within a range of 0.8-0.9, and that with respect to the wavelength λ2 is 0.7 or less, and a band of the antireflective film is within a range of 700 nm-800 nm in a state where a reflectance of a light flux perpendicularly entering a central portion of the surface in a wavelength region from 400 nm to 1200 nm is 3.0% or less.
