- Computer Confusion
- Computers do not know where the packets are going.
- Corruption
- Some packets can get unknowingly modified
- Packet Loss

Protocol Solutions
- Knowing who they are contacting
- Computer asks who they are so they know who they are contacting, and asks who
their neighbors are, so they know how to reach the packet reciever
- Confirmation
- The reciever can send a message back to make sure the packet did
not get corrupted
- Labeling
- The sender can label the packets, so the reciever can see if any packets
are missing
