- The Conversion from the linear address to physical address is done by a separate processor or a MMU
- In architecture Independent model, page conversion is a three level process which takes four steps
- 1st part is used as an index in the page directory which refers to the page middle directory
- 2nd part serves as an index to the page middle directory, there it refers to the page table
- 3rd Part used as an index to the page table, there it refers to the physical memory
- 4th Part of the address gives the offset within the selected page of memory.
- The x86 model supports a two level conversion of linear address to physical address.
- Highmem support helps upto physical memory size of 4GB being the address space of 32bit address, but Intel added four additional address pins to the Pentium Pro and created the physical address extension (PAE). Since the two level conversion supported only 32 bit addresses, the PAE has the control of supporting three level address conversion as in the Linux Architecture Independent Model.
In this post, we are going to see how to install ns-3.36.1 in Ubuntu 22.04. You can follow the video for complete details Tools used in this simulation: NS3 version ns-3.36.1 OS Used: Ubuntu 22.04 LTS Installation of NS3 (ns-3.36.1) There are some changes in the ns3 installation procedure and the dependencies. So open a terminal and issue the following commands Step 1: Prerequisites $ sudo apt update In the following packages, all the required dependencies are taken care and you can install all these packages for the complete use of ns3. $ sudo apt install g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev libxml2 libxml2-dev libc6-dev libc6-dev-i386 libc...
