Übersetzung für "Packet delay" in Deutsch

Support network detection, including network delay, packet loss, etc

For example, network scheduling can be influenced if application data must be received in its entirety, quickly, or without variation in packet delay.

In the case of the second reference time signal s REF2, this can, for example, be the Network Time Protocol used within a network, in which the relatively lower time and frequency accuracy is caused by stochastic packet delay time within a network, and the temperature-dependent drift of the synchronised local oscillator in the connected receiver.

Real-time communication is sensitive to packet loss and packet transmission impediments (in particular packet loss, delay, jitter) and can therefore be detrimental to the user's quality of experience (QoE).

This parameter may be a packet loss, a packet propagation delay that is increased relative to a threshold value, a change in the packet propagation delay, or an analysis of a difference in packet propagation delay.

For services with real-time transmission, specific quality parameters such as limits for data packet delay and loss must be complied with.

The node uses a so-called “authorization” (in this case the policy decision function PDF) to define the “quality of service” permitted for the PDP context, that is to say the bandwidth for the transmission of payload data (for example in kbit/s) and, by means of so-called QoS classes, the permitted data packet delay, as well.

If there are many open connections having high requirements regarding packet delay, these periods of time may also be very short.

If there are only a few connections having low requirements regarding packet delay, then long sleep times are possible.

This real-time behavior is determined by the minimization of data packet losses and delay times, especially as users only accept minimal delays in the case of voice signal transmission.

BACKGROUND contract between a network operator and customers may offer the customer guaranteed characteristics in the telecommunications network, such as an upper limit for the packet delay and IP delay variations, which is particularly important for IP telephony and video conferencing.

Consequently, quality characteristics are guaranteed in the telecommunications network, which are made up of the unidirectional packet delay and the parameters derivable therefrom.

Then, the packet delay is calculated from the time stamps taking into account a computer-related time slice; and this value is transmitted to control computer 40 as a measurement result and stored in database 42 .

Thus, such data packets must be sent again by the source to the destination, resulting in an increase in packet delay as well as a waste of capacity in packet-oriented data networks.

The method of claim 11 wherein packet retransmissions made in response to the quality degradation still enable the first transceiver to forward packets within a packet delay variation below 50 microseconds.

The communication system of claim 1, wherein packet retransmissions made in response to the quality degradation still enable the first transceiver to forward packets within a packet delay variation below 50 microseconds.

Packet delay (IP branch with highest delay forces other branches to be played out with delay)

The time offset or the pure data packet delay time can be determined by the communications device C transmitting a further data packet (not illustrated) with further time information and with the time information AS, BE, BS and CE back via the network node B to the communications device A. Instead of the time information AS, BE, BS and CE, the provisional delay time determined in the communications device C may also be added to the further data packet.

In this case, the data packets are delayed by the entire duration of one data packet.

In addition, the data packets are delayed in a not insignificant manner.

Usually, the transmitted packets are stochastically delayed in the LAN switch 5 .

In the second packet-formation variant, the data packets are delayed only by the duration of the required look-ahead.

This feedback message time delay period here does not have to correspond to the message time delay period by which the message packets were delayed.

The transmission of a feedback message packet is preferably delayed for at least so long until a last requested feedback message packet has been transmitted.

Because of this intermediate storage until the release of transfer, the data packets experience various delays due to the network card.

But since data packets undergo different delays in time during their transportation through the network, different values result with respect to traffic parameters, depending on the location in the network.

Since a delayed arrival of adjacent IP speech packets (delay) has a negative effect on the quality of the speech connection, various methods of time synchronizing, and thus minimizing the delay, are provided in the IP network in order to maintain the QoS (Quality of Service).

Since status information is forwarded by the first radio cell to the second radio cell—the destination radio cell—all status information is present in the destination radio cell, and it is therefore possible to continue with the regular transmission of data packets without any delay and without repeating data packets already sent to the subscriber station.

The fluctuations in the packet delays in the network node B may be eliminated on the basis of the transmitted transmission and reception time information BE, BS and BE 2, BS 2 .

In this case, the data packet DP is delayed by the duration of one control bit and fed to optical switch OSW12, as opposed to optical switch OSW11.

From a television signal, a data packet transmitted within each line in time multiplex with the picture information is separated by means of a time gate, while in addition to each data packet. a version delayed in time is formed, all the data packets are subjected to a multilevel coding and the information associated with a line and present in multiple are recorded relatively offset in time on different oblique tracks of a record carrier.

For the case in which the packets are so delayed that a broadband switching module 40 has to process the header of only a single packet at a time, the amount of circuitry required in the handling unit P and the decode and control logic 6 can be kept relatively small.

According to some embodiments, the invention is a method for selective radio communication between a radio beacon and first and second onboard units. The method includes: transmitting, by the radio beacon to the first onboard unit, a sequence of first data packets in a first frequency band, in accordance with a 5.8 GHz DSRC standard; and transmitting or receiving, by the radio beacon to/from the second onboard unit, at least one second data packet in a second frequency band, in accordance with a 5.9 GHz DSRC standard, wherein transmission of a data packet of the sequence of first data packets is delayed by a duration of the second data packet, when the second data packet appears in the second frequency band.

Aside from the influence of the implemented communication protocol, the run times are hardware-dependent and result from bit transmission times (length, payload) of the data packets, network infrastructure (delays due to coupling elements), and the network topology.
