Internet Layer Protocols (IP) |
Works on the internet layer, taking data chunks from the Transport layer, adding addressing, and creating the final IP Packet. The Internet Protocol software, then hands the IP packet to Layer 2 for encapsulation into a frame. IPv4, IPv6, ICMP. |
|
|
Internet Control Message Protocol(ICMP) |
"Is there a computer with the IP Adress of 192.168.1.115".Called automatically by applications. |
|
|
Ping |
Shows the round trip time (RTT) |
|
|
IP Packet Header |
Version: IPv4 or 6 Header Length: The total size of the IP Portion of the packets in words. Differentiated Services Code Point: Data used by bandwidth-sensitive apps Time to Live: Protocol: TCP or UDP |
|
|
Transport Control Protocol (TCP) |
When you want to be positive that the data moving between the two systems gets there in good order. Also chops up data into segments, gives the segments a sequencing number, and then verifies that all sent segments were received. If a segment goes missing, the receiving system must request the missing segments. |
|
|
User Datagram Protocol (UDP) |
When its not a big deal for data to miss a bit or two. (Connectionless) |
|
|
ACK/NACK |
Communication rules that require both the sending and receiving machines to acknowledge the other's presence and readiness to send and receive data. |
|
|
TCP Header |
Source Port, Destination Port, Sequence #, ACK |
|
|
UDP Header |
Source Port, Destination Port, Length, Checksum |
|
|
Application Layer Protocols |
TCP/IP applications us e TCP/IP protocols to move data back and forth between servers and clients.` |
|
|
IP in Depth |
TCP/IP also enables you to interconnect multiple LANs into a wide area network. Uses IP addressing to overcome the limitations inherent in ethernet networks. |
|
|
IP Adressing provides several things. |
Every machine on a TCP/IP network gets a unique IP address that identifies the machine on that network. IP addresses group together sets of computers into logical networks. Because TCP/IP network equipment understands the IP addressing scheme, computers can communicate with each other between LANs, in a WAN |
|
|
Interconnecting |
To organize all the individual LANs into a larger network, every TCP/IP LAN that wants to connect to another TCP/IP LAN must have a router connection |
|
|
Routers |
Knowns as the default gateway. Routers use network IDs to determine network traffic. |
|
|
Routing Table |
The actual instructions that tell the router what to do with the incoming packets and where to send them. |
|
|
Subnet Mask |
A string of ones followed by some number of zeros, always equaling 32 bits.EX:11111111111111111111000The tool that tells the sending computer whether the destination IP address is local or long distance. |
|
|
/ |
An IP address followed by the / and number tells you the IP address and the subnet mask in one statement. Ex: |
