摘要:
A method for managing data packets passing through an Ethernet node having multiple ingress ports and multiple egress ports, the ingress ports receiving the data packets from at least one service, and the egress ports configured with at least one Logical Transport Resource (LTR) configured as a predefined path between one of the egress ports and a destination in the Ethernet network. The method comprises mapping one or more of the services to each of the at least one LTR, shaping each of the at least one LTR to a configured rate, and transmitting data packets to the Ethernet network via the egress ports.

A method of controlling the flow of data packet traffic from a first point to at least two second point in an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links, comprises monitoring the level of utilization of a link between the first and second points, generating flow control messages representing the level of utilization and transmitting the control messages to the first point, and using the states represented in the flow control messages as factors in controlling the rate at which the packets are transmitted from the first point to the second point. A method of controlling the flow of data packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links, comprises receiving incoming data packet traffic from multiple customer connections at a first node for entry into the network via the first node, the first node having an ingress trunk, and limiting the rate at which the incoming data packets are admitted to the network via the ingress trunk.

A telecommunications system includes a network for transporting packets on a path between selected subscriber end points. The network has multiple nodes connected by links, with each node (a) pairing the forward and backward paths of a connection and (b) allowing for the injection of messages in the backward direction of a connection from any node in the path without needing to consult a higher OSI layer. A system is also provided for protecting connection paths for transporting data packets through an Ethernet telecommunications network having a multiplicity of nodes interconnected by a multiplicity of links. Primary and backup paths are provided through the network for each of multiple connections, with each path including multiple links. Data packets arriving at a first node common to the primary and backup paths are duplicated, and one of the duplicate packets is transported over the primary path, the other duplicate packet is transported over the backup path, and the duplicate packets are recombined at a second node common to the primary and backup paths.

A method of utilizing a node power architecture (NPA) system, the method includes receiving a request to create a client, determining whether a resource is compatible with the request, and returning a client handle when the resource is compatible with the request.
摘要:
A method of fault notification in a carrier Ethernet having the capability of generating and transmitting OAM packets having flag fields, comprises inserting a bit in one of the flag fields to indicate the presence of service-affecting information in the OAM packets, detecting the presence of the inserted bit at the end of a data path, and performing a service protection action in response to the detection of the inserted bit prior to parsing the information in the message. One type of service protection action is protection switching.

摘要:
Methods and apparatus improving availability of voice services controlled via IP signaling links provisioned over converged ATM and Ethernet converged network infrastructure are provided. A media gateway network element implements a Layer-2 signaling link end-to-end monitoring via heartbeat messages formulated at the ATM end to traverse the converged network infrastructure to the Ethernet end. The media gateway is provided with SPVC connectivity information and is made aware of network bridging in order to perform a Layer-2 switchover to a standby signaling link in re-establishing signaling link connectivity with a media gateway controller should a communications fault be detected. The advantages include codeployment with previous media gateway controller implemented techniques, and providing a reduction of overheads for media gateway controller implemented techniques while increasing availability by reducing exposure to service outages.
摘要:
Topical compositions are provided that have 0.5% or more of at least one personal care or pharmaceutical acid, and lightly- to moderately-crosslinked PVP, which is an effective thickener in the low pH systems. In preferred embodiments, the acid is a hydroxy acid and the composition used for personal care, or prescriptive or non-prescriptive medication indications for use on the skin, hair, scalp, foot, or lips. Also provided is the use of the topical compositions to deliver the acid(s) to the skin, hair, scalp, foot, or lips. Especially preferred is a use to reduce irritation and stinging compared to an equivalent compositions not having lightly- to moderately-crosslinked PVP.
摘要:
A chassis for telecommunication gear including horizontal circuit boards includes an enclosure forming a front-accessible circuit board slot for receiving horizontal circuit boards. The circuit board slot has first connectors for receiving mating second connectors on the circuit boards, and multiple circuit board guides for guiding and securing horizontal circuit boards inserted into the slot. Adjacent pairs of the guides are spaced to receive circuit boards of predetermined widths, and at least one of the guides is removable so that it can be re-positioned within the slot for changing the spacing between adjacent pairs of the guides to receive circuit boards of different widths. The circuit boards may be telecommunication line cards.
