Packet Routing Methods
Describe which intermediate devices the data is routed through
Connectionless (Datagram)
- Adds a destination and sequence number to each packet
- Individual packets can follow different routes
- Packets reassembled at destination (by using their sequence numbers)
Connection Oriented (Virtual Circuit (VC))
- Establishes an end-to-end circuit between the sender and receiver (before the packets sent)
- All packets for that transmission take the same route over the virtual circuit established
- Same physical circuit can carry many VCs
