CSE 58x Network Practicum:

Assignment 2:

Modify the packet counter you compiled in assignment 1 to count Ethernet,
ARP,
IP, ICMP, UDP, TCP and web (TCP Port 80) traffic.

Output of your program should look similar to this:
Packets on port 0      = 535
Packets on port 1      = 1082
ARP Packets on port 0  = 21
ARP Packets on port 1  = 21
IP Packets on port 0   = 514
IP Packets on port 1   = 1061
ICMP Packets on port 0 = 8
ICMP Packets on port 1 = 4
UDP Packets on port 0  = 413
UDP Packets on port 1  = 548
TCP Packets on port 0  = 93
TCP Packets on port 1  = 509
WWW Packets on port 0  = 54
WWW Packets on port 1  = 233
Total count of packets=1617

Some Hints & Notes:

It is only necessary to modify two files for this assignment. You may modify
others if you wish.

Ace Code:
   /opt/ixasdk/src/microace/aces/tutorial1/count_ace1/source/init.c
Microcode:
   /opt/ixasdk/src/microace/projects/Count_8_1/Count.uc

In my solution to this assignment, the following are the all the primitives
I
used. You may use any primitives which you choose. (Just for fun, if your
solution uses other primitives, let us know which ones you used, and why)

Intrinsics:
  #define
  .local
  .endlocal
Macros:
  Buf_GetData
  DL_GetBufferOffset
  Count_IncrementPacketCounter
Instructions:
  alu
  alu_shf
  xbuf_alloc
  sdram
  ctx_arb
  xbuf_extract
  xbuf_free
  immed32
  alu
  br

Make sure to note that the IP header is variable length. Your code should
take
this into account.

You are responsible for constructing a demo in which you demonstrate that
your
solution works. You may use the packet generator you used for assignment #1.
