Enter Multi-Path TCP (MPTCP), which exploits the presence of multiple interfaces on a device, such as a mobile phone that has both Wi-Fi and cellular antennas, to achieve multi-path connectivity. It's a major extension to the TCP protocol, and historically most of the TCP changes failed to gain traction. There is another way.

CCNA: TCP/IP Stack TCP/IP Stack is the most widely used protocol stack. TCP/IP stack is a conceptual model consisting of network communication protocols. It provides end-to-end data communication. It specifies how data should be packetized, addressed, transmitted, and routed across the network. Continue Reading.

CCNA: TCP 3-Way Handshake In this article, lets take a look at TCP three-way handshake and other useful information that makes TCP a reliable communication protocol. Before TCP can send any traffic, it first contacts the other device and establish a reliable and controlled connection.

CCNA: TCP Sequence & Port Number This article can be read as the second part of the previous article CCNA: 3-Way Handshake where we discussed what makes TCP a reliable protocol for transmitting information. Lets discuss the TCP SEQ and Port numbers in this article. TCP breaks this information into two pieces CC and NA.

To do that it builds the Ethernet Frame and puts its MAC address as the Source MAC address (SMAC) and layer 2 broadcast address (ff:ff:ff:ff:ff:ff). PC-2 now creates an Ethernet frame to respond to the ARP. The Network DNA CCNA RnS #13: CSMA/CD - The Network DNA CCNA RnS #12 : Ethernet Frame Type & FCS Field! IP address.

This packet is encapsulated in Ethernet frame and using the ARP entries on the Host A it forwards the frame to the default gateway on the network. Router 2 handover the packet to Ethernet 2. The Network DNA CCNA RnS #13: CSMA/CD - The Network DNA CCNA RnS #12 : Ethernet Frame Type & FCS Field!

CCNA: Ethernet Frame Today lets talk about the Ethernet Frame and its different fields. Understanding the Ethernet Frame and fields helps to understand the communication between systems and troubleshooting when things are not in place. A typical Ethernet frame looks like the one in Figure 1.
