摘要： The present disclosure provides a separate Ethernet forwarding and control plane system, method, network, and architecture with a Link State Interior Gateway route reflector for the control plan system and a layer two network architecture for the forwarding system. The present invention optionally utilizes a cloud implementation for the Designated Router (DR) or designated peering node reducing peering requirements and distributing the functionality. Through the architecture of the present invention, the Provider router is obviated by the application of layer two switches and servers. Such an architecture provides improved scaling, performance, and cost reduction.

摘要： A system for interfacing a client system in a first network domain with a Provider Link State Bridging (PLSB) domain includes at least two Backbone Edge Bridges (BEBs) of the PLSB domain. Each BEB is an end-point of a connection in the first network domain to the client system and an end-point of at least a unicast path in the PLSB domain. An inter-node trunk is provided in the PLSB domain for interconnecting the BEBs. A phantom node is defined in the PLSB domain and is notionally located on the inter-node trunk. Each of the BEBs is configured such that: an ingress packet received from the client system via the connection in the first network domain is forwarded through a path notionally rooted at the phantom node; and an egress packet destined for the client system is forwarded to the client system through the connection in the first network domain.

摘要： A compensator for optical transmission systems exploits gain tilt inherent in optical amplifiers. The amount of SRS induced spectral power gradient is determined, and the amplifier gain is changed to cause a compensating gain gradient in the optical amplifier to compensate for the SRS induced spectral power gradient. Fewer components are needed, and so it can be less expensive. It can be implemented as a simple software upgrade to existing systems. Many such compensators can be distributed through the system, without requiring a large inventory of individually specified filters. More accurate compensation can be achieved by making it dependent on the distribution of wavelengths within a band.

摘要： The invention provides a method of balancing the power level of an optical signal within an aggregate of optical signals in an amplified dense wavelength division multiplexing DWDM optical network, as well as power balancing apparatus therefor. The method involves measuring the power level of the optical signal received at an optical receiver through the optical link and referencing said measured receive power level to a nominal power level in the multiplex immediately preceding the receiver; measuring the power level of the optical signal at an optical transmitter and referencing said measured transmit power level to a nominal power level in the multiplex immediately following the transmitter; calculating a mean power level of the optical signal from said optical measurements, the mean power level of the optical signal being the mean of the power levels of the optical signal at the transmitter and at the receiver referenced to the nominal power levels in the associated multiplexes; and adjusting the mean power level of the optical signal independently of the power levels of other optical signals carried on the same optical link to the receiver so that a desired OSNR at the receiver is achievable.

摘要： A resilient virtual Ethernet ring has nodes interconnected by working and protection paths. If a span fails, the two nodes immediately on either side of the failure are cross-connected to fold the ring. Working-path traffic is cross-connected onto the protection path at the first of the two nodes and is then cross-connected back onto the working path at the second of the two nodes so that traffic always ingresses and egresses the ring from the working path. A traffic originating node, upon determining that transmitted packets are being looped back due to a fault on a primary path, is adapted to switch transmission of data packets from the primary path to a secondary path.

摘要： A method of peer interfacing a Link-State controlled network domain with an Ethernet Bridging controlled network domain. A pair of peer attachment points are provided between the Link-State controlled network domain and the Ethernet Bridging domain. The peer attachment points are respective endpoints of a set of one or more LAN segments defined within the Ethernet Bridging domain. The set of LAN segments are represented as a virtual node in the Link-State controlled network domain. The virtual node is represented in the Link-State controlled network domain as connected to each of the peer attachment points via a respective virtual link. The virtual links are configured such that frames to or from an address in the Link-State controlled network domain are forwarded over a tree passing through only one of the peer attachments points.

摘要： Previous systems and methods for personalizing web content presented to a user has been achieved in a decentralized manner by storing personal data relating to the user repeatedly by different content providing servers. Consequently, the consistency of the data stored can be inconsistent and, in some cases, incomplete. Additionally, the user does not have any control over the dissemination of the content. The present invention provides a system, apparatus and method whereby web related data is modified in communications between user equipment units and content providing servers. The modification to the web related data is carried out by a proxy server (20) having access to centrally stored personal data in a data store (22). Consequently, data provided to content providing servers is consistent, complete and the information provided by the content providing servers to the user has a higher degree of relevance to the user.
