Expert Solution & Answer
Chapter 5, Problem P14P
a)
Explanation of Solution
Protocol selection of Router 3c:
Router 3c learns about prefix “x” from the protocol “eBGP(external Border Gateway Protocol)”.
- “AS3” is connected physically to “AS2” using the OSPF connection. “eBGP” is a BGP connection that spans two ASs.
- In the given network, AS3 holds the router 3c which is physically connected to the router 4c present in AS4...
b)
Explanation of Solution
Protocol selection of Router 3a:
Router 3a learns about “x” from “iBGP”. As the router 3a is not directly connected wit...
c)
Explanation of Solution
Protocol selection of Router 1c:
Router 3a learns about “x” from “eBGP” as AS3 sends all its prefix information with AS1 because 1c is directly connected with “AS3”...
d)
Explanation of Solution
Protocol selection of Router 1d:
Router 1d learns about “x” from “iBGP” because the rest of the routers in the network use “iBGPȁ...

write a simple memory management simulator in C that supports paging. In this setup the
logical address space (216= 65,536 bytes) is larger than the physical address space (215 bytes),
and the page size is 256 bytes. The maximum no. of entries in the TLB (Translation
Lookaside Buffer) = 16.
memory.c - You are to provide your solution in a single C program named memory.c.
Your simulator needs to accomplish the following:
1. Simulate a memory management unit (MMU), which translates logical addresses to
physical addresses
1. Translating a logical address to physical address in this setup will involve the following:
Check TLB for the page. If page not found in the TLB, check the page table if the page
exists in memory. If it does not, then a page fault occurs.
2. Handling page faults involves copy the page from the backing store to memory. Since
logical address space is larger than physical address space, a page request might
involve replacing a page in memory with the new page. The page…
