1 Statistical Multiplexing https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

2 4G Key features 1 Frequency-domain statistical multiplexing, for example (OFDMA) or (single-carrier FDMA) (SC-FDMA, a.k.a. linearly precoded OFDMA, LP-OFDMA) in the uplink: Variable bit rate by assigning different sub-channels to different users based on the channel conditions https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

3 Passive optical network - Upstream bandwidth allocation 1 Through dynamic bandwidth allocation (DBA), a PON can be oversubscribed for upstream traffic, according to the traffic engineering concepts of statistical multiplexing https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

4 Passive optical network - WDM-PON 1 The multiple wavelengths of a WDM-PON can be used to separate Optical Network Units (ONUs) into several virtual PONs co- existing on the same physical infrastructure. Alternatively the wavelengths can be used collectively through statistical multiplexing to provide efficient wavelength utilization and lower delays experienced by the ONUs. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

5 Multiplexing - Types of multiplexing 1 Multiple variable bit rate digital bit streams may be transferred efficiently over a single fixed bandwidth channel by means of statistical multiplexing, for example packet mode communication. Packet mode communication is an asynchronous mode time-domain multiplexing which resembles time-division multiplexing. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

6 Multiplexing - Code-division multiplexing 1 Advantages over conventional techniques are that variable bandwidth is possible (just as in statistical multiplexing), that the wide bandwidth allows poor signal-to- noise ratio according to Shannon-Hartley theorem, and that multi-path propagation in wireless communication can be combated by rake receivers. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

7 Multiplexing - Relation to multiple access 1 A multiplexing technique may be further extended into a multiple access method or channel access method, for example TDM into Time-division multiple access (TDMA) and statistical multiplexing into carrier sense multiple access (CSMA). A multiple access method makes it possible for several transmitters connected to the same physical medium to share its capacity. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

8 Multiplexing - Relation to multiple access 1 The Transport layer in the OSI model as well as TCP/IP model provides statistical multiplexing of several application layer data flows to/from the same computer. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

9 Multiplexing - Digital broadcasting 1 In digital television and digital radio systems, several variable bit-rate data streams are multiplexed together to a fixed bitrate transport stream by means of statistical multiplexing. This makes it possible to transfer several video and audio channels simultaneously over the same frequency channel, together with various services. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

10 General Packet Radio Service - Multiple access schemes 1 This is combined with time domain statistical multiplexing; i.e., packet mode communication, which makes it possible for several users to share the same frequency channel https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

12 Packet switching - Overview 1 Packet switching features delivery of variable bitrate data streams (sequences of packets) over a shared network which allocates transmission resources as needed using statistical multiplexing or dynamic bandwidth allocation techniques. When traversing network adapters, switches, routers, and other network nodes, packets are buffered and queued, resulting in variable delay and throughput depending on the network's capacity and the traffic load on the network. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

13 Round-robin scheduling - Network packet scheduling 1 In best-effort packet switching and other statistical multiplexing, round-robin scheduling can be used as an alternative to first-come first-served queuing. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

14 Statistical time division multiplexing 1 When performed correctly, statistical multiplexing can provide a link utilization improvement, called the statistical multiplexing gain. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

15 Statistical time division multiplexing 1 Statistical multiplexing is facilitated through packet mode or packet-oriented communication, which among others is utilized in packet switched computer networks. Each stream is divided into packets that normally are delivered asynchronously in a first-come first-served fashion. In alternative fashion, the packets may be delivered according to some scheduling discipline for fair queuing or differentiated and/or guaranteed quality of service. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

16 Statistical time division multiplexing 1 Statistical multiplexing of an analog channel, for example a wireless channel, is also facilitated through the following schemes: https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

17 Statistical time division multiplexing 1 Statistical multiplexing normally implies "on-demand" service rather than one that preallocates resources for each data stream. Statistical multiplexing schemes do not control user data transmissions. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

18 Statistical time division multiplexing - Comparison with static TDM 1 Time domain statistical multiplexing (packet mode communication) is similar to time-division multiplexing (TDM), except that, rather than assigning a data stream to the same recurrent time slot in every TDM frame, each data stream is assigned time slots (of fixed length) or data frames (of variable lengths) that often appear to be scheduled in a randomized order, and experience varying delay (while the delay is fixed in TDM). https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

19 Statistical time division multiplexing - Comparison with static TDM 1 Statistical multiplexing allows the bandwidth to be divided arbitrarily among a variable number of channels (while the number of channels and the channel data rate are fixed in TDM). https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

20 Statistical time division multiplexing - Comparison with static TDM 1 Statistical multiplexing ensures that slots will not be wasted (whereas TDM can waste slots).

21 Statistical time division multiplexing - Comparison with static TDM 1 Static TDM and other circuit switching is carried out at the physical layer in the OSI model and TCP/IP model, while statistical multiplexing is carried out at the data link layer and above. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

22 Statistical time division multiplexing - Channel identification 1 In statistical multiplexing, each packet or frame contains a channel/data stream identification number, or (in the case of datagram communication) complete destination address information. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

61 Dynamic bandwidth allocation 1 'Dynamic bandwidth allocation' is a technique by which traffic bandwidth in a shared telecommunications medium can be allocated on demand and fairly between different users of that bandwidth.

62 Max-min fairness 1 In best-effort statistical multiplexing, a first- come first-served (FCFS) scheduling policy is often used. The advantage with max-min fairness over FCFS is that it results in traffic shaping, meaning that an ill-behaved flow, consisting of large data packets or bursts of many packets, will only punish itself and not other flows. Network congestion is consequently to some extent avoided. https://store.theartofservice.com/the-statistical-multiplexing-toolkit.html

63 Max-min fairness 1 Fair queuing is an example of a max-min fair packet scheduling algorithm for statistical multiplexing and best effort packet-switched networks, since it gives scheduling priority to users that have achieved lowest data rate since they became active.
