 #### Handler functions
 
 To accept connections, a libp2p application will register handler functions for protocols using their protocol id with the
-[switch][definition_switch] (aka "swarm"), or a higher level interface such as [go's Host interface](https://github.com/libp2p/go-libp2p/blob/master/core/host/host.go).

 The handler function will be invoked when an incoming stream is tagged with the registered protocol id.
 If you register your handler with a [match function](#using-a-match-function), you can choose whether
 to accept non-exact string matches for protocol ids, for example, to match on [semantic major versions](#match-using-semver).

 The "medium" over which a libp2p protocol transpires is a bi-directional binary stream with the following
