The first 32 bits indicate how many LSAs are contained in the LSU packet, and then the LSAs follow. Note that LSU packets are carried as payload of IP packets, and the IP layer can carry out fragmentation and reassembly when the LSU becomes longer than the maximum length of a packet on the underlying IP subnetwork. Problem 3.5.1 (Why all the alignment?). You can notice in this and in all following packet formats that, wherever sensible, fields and records are nicely aligned to 32-bit boundaries. Can you explain why?

Question

Can someone please help me with problem 1.5.1? I'll give a thumb up to thank for your time.
As I'm reviewing for my upcoming exam, I really need an answer from an expert in the field. 
Please do not send me an answer from chatGPT. I've got enough of that, so please be helpful. Thank you.

 

3.5 LSA Records We now discuss LSA records in some more detail. As explained above, a LSU packet (link-state-update) is simply a container for one or more LSA records. Therefore, the structure of a LSU packet (following the common header) is simple: 1 16 Number of LSAs LSA 1 LSA N 32
