 ### Protocol difference
 
 The sampling protocols can be very different:
 
 **sFlow** is a stateless protocol which sends the full header of a packet with router information
-(interfaces, destination AS) while **NetFlow/IPFIX** rely on templates that contains fields (eg: source IPv6).
+(interfaces, destination AS) while **NetFlow/IPFIX** rely on templates that contain fields (eg: source IPv6).
 
 The sampling rate in NetFlow/IPFIX is provided by **Option Data Sets**. This is why it can take a few minutes
 for the packets to be decoded until all the templates are received (**Option Template** and **Data Template**).

 The BGP information provided by routers can be unreliable (if the router does not have a BGP full-table or it is a static route).
