Asynchronous Transfer Mode (ATM) Support
The Asynchronous Transfer Mode (ATM) Support component contains networking support for ATM devices. There are four ATM communication modes:
- Using local area network (LAN) emulation, known as ATMLANE. This is the mode typically used in corporate LANs.
- Using Ethernet-permanent virtual circuit (PVC), known as ATMEPVC. This is used in certain ATM-DSL deployments.
- Using Internet Protocol (IP) over ATM, known as ATMARPC and ATMARPS. This is an alternative LAN technique suitable for IP-only networks.
- Using Winsock over ATM connections. This is used for special purpose applications.
There are no services associated with this component.
No other components interact with this component.
ATMLANE, ATMARPC, ATMARPS and Winsock do not require configuration when used over ATM.
The following table shows the settings for Ethernet-PVC configurations.
|Property/setting name||Default setting||Description|
|VPI||0||The virtual path identifier for the PVC on which the driver operates.|
|VCI||0||The virtual circuit identifier for the PVC.|
|Encap||2||Defines the encapsulation used for data transfer. Possible values are:
0 – IPv4
1 – IPv4 LLC/SNAP
2 – Ethernet
3 – Ethernet LLC/SNAP
ATM networks commonly use only one of the four possible operation modes listed above.
