Protocols
- TCP
- UDP
- Rapid STP
TCP: Transmission Control Protocol.
- Reliable Transport.
- Segments are acknowledged.
Before Segments are sent between devices, the devices go through or create a virtual connection with each other by going through what is called a Three Way Handshake. By default, for everey segment that is sent, I expect an acknowledgment in return from the other end, and if I don't receive it, I simply resend this segment. You can customize in such a way that for example we expect an acknowledgmenet for every 10 segments.
Three Way Handshake
H1 -> SYN -> H2
H1 <- SYN / ACK <- H2
H1 -> ACK -> H2
UDP: User Datagram Protocol
- Connectionless Unreliable Transport.
- Segments are not acknowledged.
Rapid STP: Rapid Spanning Tree Protocol
Uses a quick Proposal Agreement Process on point-to-point links to rapidly put the port into a forwarding state without causing disruption in services or creating a loop.
STP:
- Blocking
- Listening
- Learning
- Forwarding
RSTP:
- Discarding
- Discarding
- Learning
- Forwarding
