Furthermore, performance may be worse than these limits, such as in the case of half-duplexing and other system limitations.Ĭases where this setup is used can be found in servers dedicated for prints, files or for segmenting different departments.
#Router on a stick download
For a two-armed configuration, uploading does not need to impact download performance significantly. One-armed routers are also used for administration purposes such as route collection, multi hop relay and looking glass servers.Īll traffic goes over the trunk twice, so the theoretical maximum sum of up and download speed is the line rate. A one-armed router could be assigned addresses for each network and be used to forward traffic between locally distinct networks and to remote networks through another gateway. While uncommon, hosts on the same physical medium may be assigned with addresses and to different networks. The only difference is that the router in question may contain only a single Ethernet network interface controller (NIC) that is part of both VLANs. If they need to communicate, then a router must be placed between the two VLANs to forward packets, just as if the two LANs were physically isolated. This means that two machines attached to the same switch cannot send Ethernet frames to each other even though they pass over the same wires. A VLAN allows multiple virtual LANs to coexist on the same physical LAN. They use a single Ethernet network interface port that is part of two or more Virtual LANs, enabling them to be joined. One-armed routers that perform traffic forwarding are often implemented on virtual local area networks ( VLANs). A simplified diagram of how the router on a stick works.
