| Abstract | Ethernet devices are capable of simulating different network mechanisms. They are cheap, commonly available and guarantee throughput up to 1Gbps. Due to Ethernet’s popularity, a lot of Open Source drivers are published. Implementation of network mechanisms in a Linux driver gives the possibility of creating a structure, which can be registered in the OS as logical interface in place of the original net_device structure. This technique gives us full control of data flow in stations within the network. The IEEE 802.1Q standard provides the capability to mark frames. By alternative use of the VLAN Tag field flags can be defined and easily added to frames without changing the frame format. An advantage of this solution is the fact that the OS treats devices as Ethernet NICs and expects them to work on Ethernet frames. This provides the capability of using existing destination address resolution mechanisms. Frames can be marked with traffic class flag or as a control frame. The main disadvantage is the fact, that it does not support double tag VLANs. Using the mechanisms mentioned a simulator of an advanced computer network can be implemented. It is possible to build networks based on different topologies, using autoconfiguration and reliability mechanisms. Given the case of gigabit Ethernet NICs, one may consider using devices based on the PCI Express interface. Transfer speed reached by gigabit NICs may exhaust the capabilities of 32 bit PCI bus. Other devices sharing the bus can affect results of experiments. |
