Tunneling by means of L4 software-defined router Compositor CS10AV

With development of microchips and digital systems at the end of 80th of the last century, the virtual local area networks (VLAN) emerged. VLAN layers and processes are emulated using virtualization method by computer programs. VLAN may be formed by signals of devices of any layer (OSI model) from L1 to L4 both physical and virtual. VLAN is a complex multi-fragment system containing different topologies. Such system frequently have STUB areas, which are formed on the borders of autonomous system (AS). They represent a barrier for conducting communications. In contrast to traditional firewalls, this barrier doesn’t have ports and represents structural formation, described by MAC-address table. It is the set of switch physical addresses, forming this AS. This table has an ether analog in the form of audio signal with modulations of different types. Wavetable may be represented as digital audio signal. Each count of the table is one MAC-address. Address density depends on DSP (Digital Signal Processor) bit depth and discretization frequency of switch operation system. For 64-bit wavetable this quantity represents 2^64 physical addresses.

For audition by tunneling method, which allows listening to signal of completely closed autonomous systems, forming VLAN, routers with AUX (auxiliary) channel are suited. To such devices, also relate SDR platforms from Rohde & Schwarz, National Instruments etc. However, modern device for listening to an ether of VLAN should be much faster in deployment, virtual and broadcasted on many platforms. That is why L4 software-defined router (SDR) Compositor CS10AV ideally suited for these requirements.

SDR L4 Compositor CS10AV

SDR L4 Compositor CS10AV

It has:

  • 4 working layers multiplexed into virtual SFP with optical transceiver of 100BASE-FX standard;
  • 24 working channels (with each channel summed on optical transceiver by TDM and FDM multiplexing methods);
  • 6 preset methods (compression, expanding and noise-shaping);
  • Network capacity measurement system, containing 12 positions for frontal transmission line and 6 positions for rear transmission line;
  • Network scanning of different topologies by changing phase and signal constellation;
  • Windows 7 and Mac 10.10 platforms support.

SDR L4 Compositor CS10AV allows reproducing MAC-address table by serial and reverse methods with modulation, depending on communication between different switches. Switches are speakers in VLAN system. Each speaker should have its own AS. Autonomous system may be considered as one switch or several switches, communicating by BGP (Border Gateway Protocol). In any case, each autonomous system should coincide with one speaker. If a switch exits the autonomous system and forms separate autonomous system it also becomes a speaker. You can create autonomous system without an ability of merging, because the switch, which doesn’t enter other AS may be an independent speaker.

SDR L4 Compositor CS10AV ideally suited for listening to autonomous systems. It uses an auxiliary channel for this purpose. This method allows hearing completely closed autonomous system. Initiating an ether on SDR L4 Compositor CS10AV, which situated in one local network with the switch (AS), you can listen to this AS locally and remotely.

For the local listening, it is enough to run the SDR L4 Compositor CS10AV on one of computers in this VLAN. It can receive feedback loops with MAC-address tables by analog dialing, using a position system, containing phase, signal constellation and topology metrics of this connection. This way, it allows establishing a connection between remote autonomous systems by tunneling effect. It is reached by oversaturation of MAC-address wavetable. Such wavetable starts producing traffic if it is excited up to the self-generation point. SDR L4 Compositor CS10AV allows performing communication on a predefined area of MAC-address loop (trunk). You can choose the MAC-address loop area and listen to an ether of this subnetwork using the metrics provided. You can divide MAC-address loop in Compositor CS10AV control panel on the areas (quanta) up to the 12th of the rhythmic grid. Rotating the QAM (Quadrature Amplitude Modulation) modulation phase, you can choose between all switches in this network. Listening to the network of AS’s, it is needed to scan an ether fast on a presence of MAC-address tables. For such method, SDR L4 Compositor CS10AV presents hot signal. Each execution layer in OSI (Open Systems Interconnection) model coincides with AS working layer. For example, the first layer of OSI model is physical and coincides with real-time working layer. All analog and digital musical sequencers relate to this layer. The second layer of OSI model is informational and coincides with amplitude modulation (AM), which is used for long wave range propagation. This layer in SDR L4 Compositor CS10AV responsible for data packet forming and its translation. Optical waveguides, which AS in a standard configuration has 24, responsible for telegraph messages translation, which happens on 3rd and 4th OSI layers. Network layer responsible for messages transmission and feedback loops formation by which AS’s communicate. Transport layer responsible for translation protocol formation between these switches (AS) in one of the available finite sets. In a model with one layer finite set is two-dimensional, with two layers is three-dimensional and in a model with 3 and 4 layers finite set situated in four-dimensional space. Each finite set has only one MAC table, including all physical addresses for this reciprocity of signal constellation. Making a connection with one of the reciprocities of infinite set, you are making a connection with its finite set, which described by MAC-address table and has a defined modulation in response to signal constellation. Each wavetable describes one of the variants of finite set in current moment of time. Moment of time described by angular frequency and vector height of the exponent curvature. SDR L4 Compositor CS10AV makes available moments of time from 0 to 150 omega and exponent ascension heights up to 17000 meters. The Right Ascension up to the moment of time is not bounded by 17000 meters height and expands up to the boundaries of the nearby cosmos, where communication satellites reside. Each satellite contains a wavetable of MAC-addresses finite set and group of satellites contain all variants of finite sets. That is why satellites responsible for defined variant of infinite set and different groups of satellites attaching different finite sets form infinite set. The more satellites with defined finite sets, the more resulting approaching to their modulation. This way, Global Position System (GPS), deployed by USA at the end of 80th was first VLAN. SDR L4 Compositor CS10AV digital ether boundary is several decades of parsec (the Astronomical measure). That is why it can be used for communication networks deployment behind the boundaries of event horizon (single moment point, situated out of reach by speed of light in a unit of time). To make the intrusion more complicated modulation in SDR L4 Compositor CS10AV recorded in four-dimensional space that is why deciphering of 4-layer model is the most complex. For such model, additional amplifiers needed such as optical SFP modules. Copper ports doesn’t work on the 4th layer, because signal decay in such system more noticeable when forming the feedback loop. The so-called weak connection established, used in weak current systems and in electric networks of multi-flat buildings. Weak connection characterized by clean beep tone, which you can find in telephone connection lines. Despite of the idea that telephone networks are independent from electricity chains, they are the weak current representation of electrified building power network. Weak connection available only for discretization frequencies up to 32 kHz. It leaves the headroom for SDR L4 Compositor CS10AV for development of telephone connection lines, telephone signals and hardware for their use up to wideband signal transmission (for example music) using them. The feedback loop is a MAC-address table or hardware addresses of AS. Port is one of MAC-addresses or sample of this wavetable. In communications, the outgoing ports of devices are not studied, but devices are learned from the finite set perspective. If the system is fully autonomous and has no interfaces for interaction with external communications, then such system considered autonomous. If a system has at least one additional input besides feeder and output, which differs from temperature sensor, then such system considered operational.

SDR L4 Compositor CS10AV can listen to L4 switches or lower, up to the L1, to which all real-time sequencers are attributed. Autonomous system of kernel with 3 layers can’t communicate with autonomous system of kernel with 4 layers, because disparity of layers is critical for communication between AS. Such disparity plays a role, because loop in this case formed on the 3rd layer and transmitted on another transmission frequency, which is not corresponding to the discretization frequency of L4 switch, responsible for transport protocol. In physical networks (not in VLAN) only repeaters and signal amplifiers form such flow. In optical fiber networks, amplifying optical transceivers are used, working on the high transmission frequencies of optical signal translation.

For remote listening it is needed a full system of SDR L4 Compositor CS10AV Extended, which comes with hypervisor version 9. Compositor CS10AV Extended can perform autonomous system remote listening using AS port scanning. Using hypervisor version 9 you can select a trunk of your local network and inject MAC-address tables of other autonomous system in it. This way, autonomous system becomes available to you. You can also do this by automatic dialing with generic feeders (beacons). These beacons allow establishing a connection with remote autonomous system in whole spectrum of radiofrequencies, which amplifies the proximity effect of these networks. You can also listen to these autonomous systems in any place and remote geographic position. This way, you can listen complete autonomous system or its trunk on your local PC. There are special tools in hypervisor 9 to create a trunk. You can do this by selecting loop regeneration speed in relation to local trunk loop.

This way, entering a local trunk, you can listen to the part of AS wavetable dependent on its regeneration speed in relation of local trunk and synchronize remote autonomous systems by their tempo in real-time. You can establish a connection with complete infinite set and with separate finite set on the available period. For this you can create wave mixture from finite sets and load it into the modem, which holding a line with resulting. How many finite sets contains the infinite set depends on the resulting modulation and you can build a curvature of its behavior. You can also build behavior curve for one of the finite sets and control the network development for different modulation conditions. This way, you can view the resulting not only from the perspective of the network progression, but also from subject position, which are a part of this network.


Cut from Boosty – Calypso track (Ruslan Yusipov the year 2008 project)

An ether recording, received using SDR L4 Compositor CS10AV on 11 February 2019.

As you can hear from recording, fragments are identical rhythmically, and have similar timbral characteristics. This ether was received in local trunk and so it is working up to this moment changing in variations. Because in 2008 I mainly made resynthesis of melodies heard in my imagination, it is evident that I heard this ether earlier. It is needed to say, that an ether is Finnish, because of text translation. From the ethical perspective, I wouldn’t share chatter recording and leave only the original recording here.
