Abstract: A method of reverse migrating traffic in a network includes receiving, via an application programming interface (API), a request to migrate traffic, the request identifying a target around which the traffic is to be migrated and a peer to which the traffic is to be migrated. The computer-implemented method further includes generating one or more masks comprising weights indicating a percentage of traffic to send to each port of at least two ports. The computer-implemented method further includes stacking the one or more masks on a base mask denoting a default configuration of a network component. The computer-implemented method further includes facilitating migration of the traffic using the one or more masks. The computer-implemented method further includes performing a reverse migration from the target to the peer by removing each of the one or more masks.

Abstract: Control of a label switched path established in a network is transferred between a management plane and a control plane of the network. A node (e.g., node C) receives a message indicating a change in control of the label switched path, the message identifying the label switched path by a cross-connection identifier corresponding to an entry in the control data stored at the node which identifies data plane ingress and egress segments cross-connected at the node. Control data at the node is updated based on the identified label switched path. The message includes a list of cross-connection identifiers for nodes (e.g., nodes C, E, and F) along the label switched path. The cross-connection identifier can be an mplsXCIndex.

Abstract: In an embodiment of the present invention, a scheduling operation is performed at a lower layer based on upper layer information. In another embodiment of the present invention, an action is performed at an upper layer based on received lower layer information. Also, a scheduling operation may be performed on at least one upper layer data packet at a lower layer based on a lower layer analysis of the upper layer data packet.

Abstract: Reducing the cost of framing network packets in a virtual machine environment combines certain network objects to eliminate the cost of fully framing packets between the combined objects. In a virtual environment, for example, this allows a virtual NIC in one partition to send only data to a network provider partition and to rely on the latter to frame and route the data. A source network object, destination network object, or an intermediate network object may enable a separate intermediate network object to frame its data so that the network system may take advantage of offload framing when one or more of the intermediate network object's ports has the capacity to offload framing.

Abstract: An object is to select destination mobile stations so as to prevent directional beams directed to the respective mobile stations from interfering with each other in application of a directional antenna, and to allocate the radio resources to the mobile stations thus selected.

Abstract: A network management system, for example for use in a telecommunications network, includes a performance measurement tool for carrying out one or more performance measurements relating to physical or logical components of the network. A performance management controller includes a control unit, a list of performance measurement groups, a list of logical/physical components and a list of predefined time schedules. Upon receiving information indicating that a performance measurement threshold has been crossed, the control unit determines whether the group of performance measurements associated with that threshold is active, and if not, automatically activates the appropriate performance measurement group. In this way, the system is able to adaptively change the performance measurements in response to actual performance measurements, thereby ensuring that the most appropriate measurements are carried out.

Abstract: A technique for performance-monitoring of a standard SONET signal involves first converting the optical signal to an electrical signal, removing in the framing signal time slot the framing signal for leaving only the framing signal noise in such time slot, and separating the framing signal noise from the data signal for viewing as a measure of the quality of the SONET signal.

Abstract: A word-based interface between a MAC and a PHY, allowing for variable pin counts, variable PHY and MAC data speeds, and variable numbers of connected PHYs. The word-based interface allows for the PHY to provide PHY-to-MAC words to the MAC, and for the MAC to provided MAC-to-PHY words to the PHY, where the PHY-to-MAC words are synchronized with the MAC-to-PHY words. Data and commands are provided in fields of the words, and may be time multiplexed over the interface. Circuits within the MAC and PHY allow for the MAC to detect if a PHY is present, the number of active pins, and the number of PHYs connected. The reset and synchronization signals are integrated into a single reset/sync signal. Identification data is exchanged between the MAC and PHY so that the proper device driver for the PHY may be loaded independently of the BIOS.

Abstract: A QoS management apparatus in which the quality of the requested QoS for each path and different values of the state are managed. A QoS monitor, a registered QoS, and an operation determining function are provided for each path, and the QoS is precisely managed.

Abstract: Methods, apparatuses and systems are provided for use in a wireless routing network. One apparatus, for example, includes an adaptive antenna that is configurable to receive a transmission signal from a transmitter and in response transmit corresponding outgoing multi-beam electromagnetic signals exhibiting a plurality of selectively placed transmission peaks and transmission nulls within a far field region of a coverage area. The adaptive antenna may also be configured to selectively receive at least one incoming electromagnetic signal directed through the coverage area. The adaptive antenna includes at least one antenna array and logic. The antenna array has a plurality of antenna elements. The logic is operatively coupled to the antenna array and configured to selectively control the placement of the transmission peaks and transmission nulls within the outgoing multi-beam electromagnetic signals.

Abstract: Previously it has only been possible to allocate unique internet protocol (IP) addresses to nodes in open systems interconnection (OSI) communications networks such as those using integrated IS-IS, by manual configuration. This is time consuming and expensive because an operator must travel to the site of the node. By exploiting features of the OSI routing protocol the present invention enables IP addresses to be automatically allocated to the new network nodes. This is particularly advantageous for new intermediate systems such as optical multiplexers with integral routers. Once an IP address has been allocated, the node can be managed by a remote management system or operator using internet protocol methods.

Abstract: The invention relates to communication processing system and communication processing method which can process data at a high speed by efficiently and smoothly executing data processings for transmission and reception. The system has small scale memory areas which are independent in layers and a large scale memory area which is common to the layers. Data of a small size is transferred to the small scale memory areas and the large scale memory area is released.

Abstract: An applications programming interface 20 to a telecommunications management network includes a command language interpreter 24 and a compiler 40. A command string input/output format is provided, the command strings 42 including network management parameters. The interpreter includes interpreter scripts for converting the network management parameters between the command string format and a network management protocol compatible format. The compiler compiles interpreter scripts for encoding and decoding user defined parameter types, which are then loaded dynamically to the interpreter. The interface provides a convenient "command line" API, while at the same time permitting extensions to the interpreter in a dynamic manner.

Abstract: Interconnection of local area networks, which use a protocol of the "Source Routing" type, through a wide area network involves pieces of interconnection equipment each having a configuration memory which avoids systematic broadcast of discovery frames on the wide area network. Machine learning by these pieces of interconnection equipment stores in respective configuration memories the address of the interconnection equipment through which a local area network containing a destination station is situated. For a given size of routing information field, the maximum number of interconnected networks is doubled.

Abstract: An improvement in the Open Systems Interconnection model in which Service Access Points can be established directly between peer entities in the same layer of a protocol stack. This direct seamless peer-to-peer communication is vastly superior to the use of a higher level relay function to set up and manage the communication path. In particular, setup messages are exchanged between the peer entities and a higher layer to create the Service Access Point between the peer entities. The setup and management capabilities are contained in each of the peer entities and hence no relay function is required after the peer Service Access Point, substantially speeding up the communication and reducing the management overhead.
