Identify and briefly describe the four parts of a Multiprotocol Label Switching (MPLS) header.
What will be an ideal response?
The MPLS header consists of four parts:
• Label A unique identifier, used by MPLS-capable routers to determine how to move data.
• Experimental Bits (Exp) A relative value used to determine the importance of the labeled packet to be able to prioritize some packets over others.
• Bottom of Label Stack (S) In certain situations, a single packet may have multiple MPLS labels. This single bit value is set to 1 for the initial label.
• Time to Live (TTL) A value that determines the number of hops the label can make before it's eliminated

Enhance the program you wrote for Programming Project 8 in Chapter 8 to give it a GUI that allows the user to write and read objects of type Pet to a file. Include a menu with options to create a new file, read an existing one, or exit. Create two files—named dogRecords and catRecords—and list them in a submenu under the read option. Hint: You can use this program to create the files dogRecords and catRecords. This project will require two testing phases, one before and one after creating the files, but that is not a major problem.
This is one of the more complicated problems in the text. While it is not difficult to create the menus, building and viewing files is another matter. As is often the case, it is easier to create the interface first, then add functionality a piece at a time. The user interface for the solution shown here a main window to display or enter data, and a pop-up window to enter the file name. The data window does not show text areas until a file has been opened to read or write. One dilemma is that the view option cannot be tested unless files with PetRecord records can be built, and, vice versa, the build option cannot be tested unless it is possible to view the files. One way around this dilemma is to use PetFileReadOrWrite from Chapter 10 Programming Project 9 to create the files
