Abstract:
A disclosed Internet Linked Network Architecture delivers telecommunication type services across a network utilizing digital technology. The unique breadth and flexibility of telecommunication services offered by the Internet Linked Network Architecture flow directly from the network over which they are delivered and the underlying design principles and architectural decisions employed during its creation. The present invention supports current telecommunication and voice over IP standards and applications. This new network not only replaces the telecommunication network presently in place, but it also offers a more feature rich and cost effective alternative. For example, traditional telecommunication switches are more expensive, less reliable and slower than the faster digital data switches utilized in the present invention. Furthermore, the programmable nature of the digital devices comprising the present invention allows the new network to be built with a scalable and extensible architecture, providing the flexibility necessary to incorporate new or future digital enhancements. The inventive network is designed as a complete replacement for the traditional telecom network. The disclosed architecture allows for this network to connect to traditional networks and allows for an upgrade path. The design is robust and scalable so this network can introduce new features and functionality while preserving the quality of traditional networks.
Abstract:
Method and arrangement for network resource management in a communication network,especially related to transfer of content. A content resource broker is introduced, which dynamically manages resources based on the size of the content to be transferred. The method and arrangement involve the obtaining of information on current and future network capacity, which is available for transfer of content; the receiving of a request from a requesting entity concerning resources for transfer of a content C; and the determining of whether the available network capacity within a predetermined response time is sufficient for transferring the content C before the predetermined response time has expired.
Abstract:
A system and method for load balancing network resources. Network performance information regarding data flow through a network is gathered using performance information packet data packets. The data flow is distributed through access points of the network using connection control admission control engines. The distributing includes routing the data flow to more efficiently use the network resources based on the PIP data packets.
Abstract:
The invention relates to a method for the mapping of packet flows onto bearers in a communication system. The establishment of a session between a terminal and a remote terminal is initiated. Information on the session and packet flows associated with it is received to a second network node. A first network node obtains from the second network node one or two packet classifiers for each of the packet flows. At least a first bearer belonging to the bearers is established between the terminal and the first network node. A packet associated with the first bearer is received in the first network node. The packet is matched with the one or two packet classifiers associated with each of the packet flows to determine a first packet flow among the packet flows. A mapping is established between the first packet flow and the first bearer in the first network node.
Abstract:
In a system in which several data links are available for the transmission while one respective sending unit is allocated to the data links to temporarily store data that is to be transmitted via the respective data link, data packets containing non-real-time critical data are subdivided into fragments of variable sizes prior to forwarding to a sending unit. Data packets containing real time-critical data are preferably forwarded to a sending unit without being fragmented. Additionally, a minimum fragment size can be predefined for the fragmentation process.

Abstract:
A method is provided in one example and includes querying for a total capacity for data transmissions for a local network segment, and identifying an available capacity for the local network segment by subtracting a sum of current aggregate consumption of the local network segment from the total capacity. The method also includes comparing the available capacity to a requested capacity that is generated by a network element for a specific communication session. If the requested capacity is equal to or greater than the available capacity, the request is withheld and not transmitted. In more specific embodiments, if the requested capacity is less than the available capacity, the request is transmitted. The query can be communicated to a gateway. In still other embodiments, the query includes a specific query as to a capacity allocated for video data and the network element is a set-top box.
Abstract:
The communication control apparatus 100 of the present invention carries out complementary communication by selecting plural wireless communication paths 10A, 10B between a wireless communication apparatus 300 and itself. The communication control apparatus 100 includes: a calculation unit (135, 137, 105) for calculating, on the basis of a packet received by way of each wireless communication path, ideal signal-reception timing and allowable limit timing of the received packet at the wireless communication path; a memory unit (107) for receiving and memorizing variation absorbing time at the received packet in the application transmitted from the wireless communication apparatus; and a selection unit (105) for selecting the plural different wireless communication paths such that variation request time, obtained on the basis of the ideal signal-reception timing and the allowable limit timing at each wireless communication path calculated by the calculation unit, does not exceed the variation absorbing time in the application memorized in the memory unit.
Abstract:
The present invention relates to an arrangement for controlling communication of data packets through one or more communication networks or network domains. It comprises means for identifying real-time or non-bursty data packet traffic, for separating real-time data packet traffic from bursty data packet traffic, for controlling the admission of real-time data packets and it further comprises or communicates with means for keeping information about the amount of real-time data packet flows that is admissible and for keeping information about current number of admitted and/or non-admitted real-time data packet flows. Means are also provided for establishing whether a packet or packets of a real-time data packet flow is/are admitted or not, such that generally all packets of a real-time IP data packet flow either can be admitted or rejected.
Abstract:
Message publish/subscribe systems are required to process high message volumes with reduced latency and performance bottlenecks. The end-to-end middleware architecture proposed by the present invention is designed for high-volume, low-latency messaging by, among other things, reducing intermediary hops with neighbor-based routing, introducing efficient native-to-external and external-to-native protocol conversions, monitoring system performance, including latency, in real time, employing topic-based and channel-based message communications, and dynamically optimizing system interconnect configurations and message transmission protocols.
