11 Mar 2002TL;DR: In this paper, a routing unit receives a packet from each port, and uses header information contained in the packet to judge whether the packet should be transmitted to the function unit, and if so, the routing unit adds a first identifier to the packet and transmits it to a transmission unit.
Abstract: A routing apparatus includes a plurality of routing units and function units. The routing unit receives a packet from each port, and uses header information contained in the packet to judge whether the packet should be transmitted to the function unit. In the case where the packet should be transmitted to the function unit, the routing unit adds a first identifier to the packet and transmits it to a transmission unit. The function unit receives the packet containing the first identifier from the transmission unit, and executes a predetermined processing for the packet. The function unit adds a second identifier to the packet and transmits it to the transmission unit.

27 Jan 2009TL;DR: In this article, a traffic control device for a Quality of Service-aware packet-based network comprises detection means (52) for detecting packet flows in a packet stream (46) by preferably repeatedly performing a data packet inspection on the packet stream and sending means (58) for sending the assignment information to a resource control device (44) for causing the resource controller device to allocate the assigned resource.
Abstract: A traffic control device (50) for a Quality of Service-aware packet-based network (10) comprises detection means (52) for detecting packet flows in a packet stream (46) by preferably repeatedly performing a data packet inspection on the packet stream (46), the data packet inspection being neither based on signaling information nor on application awareness, determining means (54) for determining a flow parameter, in particular a flow rate, of at least one of the detected packet flows, assignment means (56) for generating assignment information assigning a resource of the packet-based network (10) to the at least one detected packet flow in dependence of the detected flow parameter, and sending means (58) for sending the assignment information to a resource control device (44) for causing the resource control device (44) to allocate the assigned resource. In such a way, reliable and cost-efficient quality of service management in a packet-based network (10) is facilitated.

01 Jun 2011TL;DR: In this paper, a packet transmission apparatus with a limited arrival deadline was provided. But the packet transmission scheme was not considered in this paper, and the packet retransmission mechanism was not discussed.
Abstract: A packet transmission apparatus is provided. The packet transmission apparatus transmits a packet having a limited arrival deadline through a best-effort network. The packet transmission apparatus includes an automatic packet retransmission section to control retransmission of an undelivered packet, a forward error correction coding section to add a redundant packet to a data packet block, and a redundancy determining section to dynamically determine redundancy of the redundant packet based on observed network state information, so that a loss rate after error correction at a receiver achieved by only the retransmission of the undelivered packet satisfies an allowable loss rate after error correction.

26 Aug 1996TL;DR: In this paper, a packet switching communication network (10) includes a number of switching nodes (16) and at least one data processor (20), each of which is configured to perform a network processing function, such as packet broadcasting (74) or error correction (60).
Abstract: A packet switching communication network (10) includes a number of switching nodes (16). The switching nodes include a switch (18) and at least one data processor (20). When selected packets (34), as identified by routing codes (40), arrive at one of the switching nodes (16), they are passed (58) to the data processor (20). The data processor (20) is configured to perform a network processing function, such as packet broadcasting (74) or error correction (60). In performing these functions, user data (38) conveyed by the selected packets (34) are processed to generate processed packets. The processed packets are re-introduced to the switch (18) and routed onto their destinations.

TL;DR: In this paper, a method and system for scheduling data in the down, or forward, link, on a per packet basis in a wireless telecommunications network is presented, where the scheduler determines the order of packets to be sent from multiple queues based on per IP QoS, real time channel condition and real time buffer occupancy.
Abstract: A method and system for scheduling data in the down, or forward, link, on a per packet basis in a wireless telecommunications network. The scheduler determines the order of packets to be sent from multiple queues based on per IP QoS, real time channel condition and real time buffer occupancy. The scheduler determines the necessary support link adaptation on a per packet basis based on per packet QoS and the channel condition. The scheduling system and method take into consideration both upper layer per packet QoS, for example packet delay bound, and the real time channel condition (C/I) for each mobile terminal. The method of the present invention also determines the layer 2 frame length for each scheduled packet.
