I'm doing a wide research on DOS. In order to simulate DOS, I have to build
a network that shows a DOS case. (DOS is when the legitimate users can not
access a service. for example when you request a web page and can 't get a
response. this is because the attacker sending many web requests
I'm working on TCP models and I'm edition tcp.cc andd tcp.h files.
what I want to know, how do I access the node by its Id as I'm assigning in
tcl for each node a number (as you all know).
I tries to create an object from Node and access the variable nodeid_,
however the returned value
I'm doing research on TCP wired model. Can anyone tell me what is the
function responsible for sending packets in TCP and receiving ?
I found many for sending in TCP.cc file. However, it seems the one
responsible for sending in agent.cc?
Thank you in advance
I built a model based on UDP protocol. Based on my scenario, I need to
control the send and receive in UDP for specific flow. For example, I need
to drop the packets after receiving certain number of packets from specific
flow. As I know, I need to modify the c++ code inside UDP model,
I 'm working on scenario in wired network-udp protocol. Any help on drop
packets other than drop (p). I tried this method drop(p) but it doesn't drop
I sent this question many times, with no help!
ANY HELP ON THIS PROBLEM IS HIGHLY APPRECIATED.
I've been reading the below blog :
I found this sentence Note that drop(p) is a function of class Connector,
and therefore must be invoked from within the scope of class Connector.
I just want to understand who is responsible for sending the packets in ns2.
In each layer 4 protocol ( TCP or UDP) there is a function for send and
receive. However,I read in other blog http://t-issariyakul.blogspot.com.
-that the function in Agent.cc is the one responsible for sending
I need to put specific algorithm in certain nodes. I'm not sure on which
level I shall put it. In other words, shall I put in TCL code or in C++
My algorithm is very simple I just check the node id and add it to an array.
Please guys, your help on this issue is highly appreciated.
I 'm modifying the UDP.cc code and I want to check at certain time in which
node the packet in? I tried to use the source (src_) of the ip header
however, it printed the source of the original packet. In other words, in
the following example:
A---BC A sends to C packets
In wired network ... how do I get the node id at certain timeIn other
words, I'm adding block of code in droptail.cc and I need to perform
some action for certain node in the topology.
I have tried :
Node * node= Node::get_node_address (1)
int nodeNumber =node-nodeid_;
It is not
