摘要:
A communication method for a transmission-side node and a reception-side node performing transmission and reception via a communication line in a predetermined cycle includes: causing the transmission-side node and the reception-side node to transmit identification information indicating a status of an event of transmission of object data to the communication line in the predetermined cycle; if a new event of transmission of the object data occurs, causing the transmission-side node to update a value of the identification information and transmit the updated identification information together with the object data to the communication line in the predetermined cycle; and causing the reception-side node to receive the object data and the updated identification information, and upon completion of reception of the object data corresponding to the updated identification information, update a value of the identification information and transmit the updated identification information to the communication line in the predetermined cycle.

The present invention provides a method and an apparatus for transmitting and receiving packets in a broadcast and communication system. The present invention comprises: generating a repair packet by encoding a source packet with an error correction code; and transmitting the source packet to a first network and transmitting the repair packet to a second network, wherein the number of repair packets is determined according to the maximum transmission delay values of the first and second networks.

A network communication system includes a network node that is configured to create and terminate sessions between talkers and listeners connected to different Layer 2 networks. The talkers and listeners may be configured to reserve network paths and communicate data streams in accordance with a Layer 2 reservation protocol, such as Stream Reservation Protocol. The talkers and listeners in the different Layer 2 networks may reserve network paths and communicate data streams through a network node configured to manage sessions using a Layer 3 session protocol, such as Session Initiation Protocol. The network node may reserve the network paths and enforce quality of service in accordance with the Layer 2 reservation protocol so that the talkers and listeners in the different Layer 2 networks may communicate data streams to each other.

Method and apparatuses for controlling a peer-to-peer communication involving media communication between a subscriber (A) and one or more opposite peers (B, C, D). When a policy node (300) detects that the peer-to-peer communication is activated for the subscriber, session parameters are determined (3:4) for the media communication based on predefined peer-to-peer service rules configured (3:1) at the policy node. The session parameters are then implemented (3:6) in an access gateway (304) that controls network resources for the media communication.

The present invention is directed to the aggregation of data packets and to super packets for transmission across a communication network. In accordance with the present invention, an identifier associated with individual data packets is examined to determine whether such individual packet is suitable for inclusion in a super packet containing data packets associated with individual data flows. The identification may be included within a field established for a purpose other than marking an individual data packet in connection with forming aggregate packets. In particular, preexisting data fields may be utilized to identify packets for purposes of forming aggregate data streams.

To communicate in a wireless network, resources of at least one node (20A) of the wireless network are pre-allocated (44). The pre-allocated resources (44) comprise resources normally allocated in response to a call setup request. A first call setup request is received after pre-allocating the resources, and in response to the first call setup request, a packet-switched real-time, interactive communications session is established through the wireless network using the pre-allocated resources of the at least one node (20A).
