What is the CVI?

The Virtual Channel Identifier (VCI) distinguishes between digital stations (also called circuits) that are generated in the packet/cell and that have changed systems. The VCI contains many courses, each communication station, and can manage the unique identification of each developed circuit. The VCI can also be referred to as a digital circuit identification (VCI).

The LCI can be used in mobile networks with asynchronous transfer mode (ATM). Virtually every ATM cell head is equipped with a VCI, and it is actually only a 16-bit digital range for rational digital transmitter identification. Each LCI together forms a Virtual Path Identifier (VPI) to enable the complete transfer of data packets. The common digital identifiers VCI and VPI ensure that the data is transmitted correctly along the route.

What is the CPI?

A virtual path identification (VPI) is a transmission identification that refers only to the system path by which a mobile packet arrives at the destination node in asynchronous transport mode (ATM). VPIs are 16-bit digital headers in mobile ATM transmissions.


ATM cells – the average number of ATM switching trains. VPI links provide access to buttons where the package can be tracked manually. Each course includes a certain percentage of the bandwidth. The number of channels depends on the capacity. A CPI is assigned to each newly created system.

As an ATM cell, it passes through the system; it is usually powered by several ATM switches. The VPI will inform you of the buttons that you can use to manually follow a referral or to indicate exactly which method to choose. Hence the name Virtual Path Identifier. The VPI can be used with the Virtual Channel ID or even the Digital Channel ID VCI.

VPIs are interoperable via virtual station IDs, allowing the entire mobile ATM switching system to be used. ATM cells create digital circuits and channels, resulting in unique networking throughout the functionality of the station transmitting information. The Digital Station ID refers to the circuit/channel used, while the VPI corresponds to the correct path to the desired destination server.
ATMs enable fast and direct communication. They also create peaks and ensure identification as part of the control. The numeric identifier applies to all paths and circuits created by this ATM modification; they are actually called virtual channel identifiers and virtual path identifiers.

Relationship between the CVI and the CPI

The Virtual Channel Identifier (VCI) can simply be a unique identifier that identifies a particular digital circuit in the system. It’s just a 16-bit discipline of an ATM mobile header. The VCI can be used in conjunction with any Virtual Path Identifier (VPI) to determine the next destination as it travels through a series of ATM switches to reach its destination.

ATM switches use the VPI/VCI ranges to determine the VCL (Digital Channel Connect) of the next system a cell needs to pass through on its way to its destination. The role of the VCI is similar to the channel ID of the DLCI Datalink in Frame Relay, with the awful number of channel groups in X.Twenty-five.

ATM connection with VCI and VPI

The ATM works like a channelled transport cover, with vein retractors. This includes the concept of digital channels (VPs) and digital channels. Each Mobile ATM contains an 8- or 12-bit Digital Path Identifier (VPI) and a 16-bit Digital Channel Identifier (VCI) defined in the header. The VCI can be used in conjunction with the VPI to detect the next target as it travels through the ATM circuit to its destination.

The duration of such an IPV may vary depending on the mobile communications provided through the user’s network port (near the periphery of such a system), if provided through the network port (within the system). When these cells pass through the ATM system, the offset is obtained by simply changing the VPI/VCI value (tag exchange). Although the VPI/VCI values are not necessarily constant at one end of their connection, the idea behind the system is stable (unlike the Internet protocol address). Each package can return to its destination via a different path than the others). ATM switches use the VPI/VCI ranges to accurately detect the hyperlink to the digital station (VCL) of the next system the cell must pass through on its way to its destination.
The role of the VCI is very similar to that of this Information Link Identification (DLCI) on the frame relay and a reasonable station number and likely range of the group of stations in X.25. Another attraction of using electronic circuits is that they can be used as multiplexing cover, allowing the use of different products and solutions (e.g. voice, frame relay, n * 6 4 stations, internet protocol address). The VPI is also useful for creating a conference table with various digital circuits according to the usual methods.
