TCP and UDP.

– TCP and UDP common factors.» Transport layer or Layer 4 protocols.

• Responsible for the delivery of network data between nodes.

– Transmission Control Protocol (TCP).

» Reliable delivery method.» Ensures that all packets are received.» Uses acknowledgements as a means of error

correction.» Establishes flow control to reduce error rate and ensure

proper delivery.

– User Datagram Protocol (UDP).» Best effort delivery method.» Sends data, but doesn’t care if the packets are all

received.» No error correction.» Speed and low network overhead is what concerns UDP.

Page 7

Common ports and protocols.

– HTTP (Hypertext Transfer Protocol).» The primary protocol used to transfer data over the

Internet.• Assigned to port 80.

– HTTPS (Hypertext Transfer Protocol Secure).

» The primary protocol to securely transfer data over the Internet using SSL (Secure Socket Layer) or TLS (Transport Layer Security) technology. In actuality, SSL should no longer be used.

• Assigned to port 443.

– NetBIOS (Network Basic Input/Output System).

» Originally developed to allow hosts to be able to communicate with servers.

• Assigned to ports 137-139.

– SMTP (Simple Mail Transfer Protocol).

» The protocol used to transfer email from a client to an email server; it is also used to transfer email between servers.


– POP3 (Post Office Protocol v3).» The protocol used by clients to retrieve email from

servers. Once engaged, POP3 downloads all messages from the servers. The user cannot access email messages until they have been downloaded.


– IMAP (Internet Message Access Protocol).

» A protocol used by clients to access email on email servers. Allows the client to administer and organize email on the server into folders.

– SIP (Session Initiation Protocol)» A protocol that is most commonly used to set up and

tear down multimedia communication sessions (e.g., a VoIP session uses SIP to establish and terminate the session).

• Assigned to ports 5060 and 5061.

– RTP (Real-time Transport Protocol).» The protocol that is commonly used to format and

deliver multimedia or streaming content (e.g., RTP handles the flow of packets in a VoIP session after SIP has established the connection).

– MGCP (Media Gateway Control Protocol).

» A protocol that defines a means of communication between a packet switched network and circuit switched network (e.g., the PSTN). It can be used to set up, maintain, and terminate calls between multiple endpoints (e.g., teleconferencing).


– H.323.» A protocol that provides a standard for delivering video

over IP networks. It defines how real-time audio, video, and data are to be transmitted. It provides signaling and bandwidth control.

What was covered.Common networking protocols I.

TCP uses reliable delivery methods, while UDP uses best effort delivery methods. UDP has less overhead, but it also has no mechanism for error correction.

Topic
