One layer up we fine bridges and switches, which operate at data link layer. They can accept(2),examine the MAC address and forward the frames to a different network while doing minor protocol translation in the process. In the network layer, we have routers that can connect two networks. If two networks have(3)network layer, the router may be able to translate between the packer formats.
