i have always understood the frame to be the Layer 2 only construct.

Once you get L3 involved (even in you case listed above) its a packet.

No hard science just years of how its been done.

adding to vmiller..

The Network Access Layer is Ethernet, ATM, Frame Relay and so on. Anything that fits in this layer is a FRAME. Frame is a lower-level idea. Frames are used on cabling systems. The cabling system can have multiple stations connected on the cable. A frame has framing to mark the beginning and end, sender and receiver addresses to indicate the stations on the cable, low-level control information, and a payload.

The Internet Layer is where IP was defined. Anything in this layer IS A PACKET.A packet is a block of user data, such as a piece of an e-mail message, with a network address pasted onto the front. Packets are used on networks. The network equipment looks at the network address and uses this information to make a route decision.

Hi,

run Wireshark in your LAN for a while.

You will see TCP segments inside IP packets inside Ethernet frames probably.

This will illustrate different network layers for you.
