How does the Internet design accommodate heterogeneous networks that each have their own packet format?
What will be an ideal response?
To overcome heterogeneity, the Internet Protocol defines a packet format that is
independent of the underlying hardware. The result is a universal, virtual packet that can be
transferred across the underlying hardware intact. The Internet packet format is not tied directly to
any hardware. The underlying hardware does not understand or recognize an Internet packet.
