摘要:
A generalized multiprotocol label switching (GMPLS) non-enabled network gateway for routing between a GMPLS enabled network and a GMPLS non-enabled network for connection between the GMPLS enabled network and the GMPLS non-enabled network, and an operating method for the GMPLS non-enabled network gateway are provided. The GMPLS non-enabled network gateway may include a border gateway protocol (BGP) routing unit to exchange routing information between a first GMPLS enabled network and a third GMPLS enabled network using a BGP, and a resource reservation protocol signaling unit to search for a path to another network using the routing information and to perform inter-autonomous system (AS) signaling by including a control plane of the first GMPLS enabled network or the third GMPLS enabled network and a signaling interface applying an out-of-band method.

Provided are a method and apparatus of controlling a Label Switched Path (LSP) of a Resource Reservation Protocol-Traffic Engineering (RSVP-TE) protocol, which may define an available label in an End-to-End range when a label is not changed by transit nodes, and is determined only by an external management system or a manager, or an ingress node or an egress node, thereby more simply and effectively operating the RSVP-TE protocol, and removing limitations in functions of nodes such as path calculating.

Provided is an access node including: a receiver to receive subscriber information associated with a subscriber from a residential gateway of the subscriber and a service request from the subscriber; a storage unit to store registration information comprising the subscriber information and service information received from a plurality of service providers; and a processor to provide, to the residential gateway, a service corresponding to the service request based on the subscriber information.
摘要:
Provided are a system and a method for measurement voice over Internet protocol (VoIP) quality of experience (QoE), and a compensation method. a method for measuring QoE for a VoIP telephone service in real time, and claiming aftertreatment on the basis of the measurement quality. The present invention measures subjective or objective quality for an actually generated call, and allows the subjective or objective quality to be linked with aftertreatment such as compensation.

A side-view type light emitting device includes a package body, a lead frame, and a light emitting diode (LED). The package body has a first surface provided as a mount surface, a second surface disposed on a side opposite to the first surface, and lateral surfaces disposed between the first surface and the second surface. The package body includes a recessed portion disposed on a lateral surface corresponding to a light emitting surface of the lateral surfaces. The lead frame is disposed in the package body. The LED chip is mounted on a bottom surface of the recessed portion. Protrusion parts protruding toward the LED chip are disposed in regions adjacent to the LED chip of facing inner sidewalls of the recessed portion, respectively.
摘要:
In an environment including a first service providing system and a second service providing system, the first service providing system forwards common authentication information received from a terminal to the second service providing system to perform authentication when the terminal that is located in a service provision area of the first service providing system and has requested connection is a visiting user. The first service providing system makes a connection request to the second service providing system based on the authentication result that is provided from the second service providing system based on the common authentication information. The second service providing system provides the communication service to the terminal by using the resources of the first service providing system.
摘要:
A light emitting device includes: a substrate having opposed first and second main faces; a light emitting element mounted on the first main face of the substrate; and a driver integrated circuit (IC) formed in an area corresponding to a lower side of the light emitting element within the substrate, and adjusting the amount of current applied to the light emitting element. Since the circuit provided to drive a light emitting diode (LED) is integrated within the substrate, a compact light emitting device having an integrated structure can be obtained.
