Channel bundling
With channel bundling , several connections are used simultaneously for data transmission in order to increase the data transmission rate.
Previously, the term referred exclusively to the bundling of ISDN B channels , usually from both B-channels of an ISDN - basic access . Since the B-channels in the network may have different transit times , the terminals must take precautions that enable the receiving terminal to synchronize the data again in terms of time .
In a somewhat broader sense, channel bundling is also used in the radio area in addition to ISDN to bundle different radio channels and thus to form a common ( virtual ) radio channel (or line ). Various trunked radio systems make use of this. In addition, frequency channels are also bundled in the DSL area in order to increase the data throughput of such a ( virtual ) connection (see also broadband network ).
Today it is also used to describe the bundling of several IP connections via different channels, which are marketed as Viprinet -VPN or by Telekom as a DSL-LTE hybrid. For such channel bundling, however, a remote station in a data center is required in addition to the special router at the location. This must either be rented or is made available by the provider in their backbone.
