Internet Transport Layer Protocols
To date, we've compared the 7-layered OSI/ISO model to the
4-layered TCP/IP protocol suite.
We've recently focused on how TCP/IP delivers its packets -
using 32-bit IPv4 addresses to deliver data,
first to the correct network, and
then to the correct host on that network.
We've also focused on how the protocols are embedded,
within each other:
Pedantically, we could say that Ethernet delivers the IP packet to
the correct interface on that host.
