[jira] Created: (DIRMINA-389) Create a Connection Throttle Filter
Create a Connection Throttle Filter
-----------------------------------
Key: DIRMINA-389
URL: https://issues.apache.org/jira/browse/DIRMINA-389
Project: MINA
Issue Type: New Feature
Components: Filter
Affects Versions: 2.0.0-M1
Environment: All
Reporter: Mark Webb
Assignee: Mark Webb
Priority: Minor
Fix For: 2.0.0-M1
Create a filter that will throttle connections. This filter will monitor newly created sessions and if new connections from the same IP address come in too fast, drop the connections.

Not a problem. I will take this one and make the change. I think I was
overly-influenced by the ConcurrentHashMap discussions :)

Re: [jira] Work started: (DIRMINA-389) Create a Connection Throttle Filter
Posted by Mark Webb <el...@gmail.com>.
I just updated the code to hopefully make things more clear. What I now do
is perform a lookup in the map for the IP address, if the IP address exists,
then I test get the value from the map with the key being the IP address.
The value from the map is the last connected time. This time and the
current time are subtracted and if the result is less than the interval
time, then the session will be closed. On each call to this method, I
updated the map with the current time. This will ensure that the last
connected time from a specified IP address will get updated per connection
attempt.
I hope this clears things up.

The adjuration to be "normal" seems shockingly repellent to me; I see
neither hope nor comfort in sinking to that low level. I think it is
ignorance that makes people think of abnormality only with horror and
allows them to remain undismayed at the proximity of "normal" to
average and mediocre. For surely anyone who achieves anything is,
essentially, abnormal.

Hmm? I thought the introduction of ConnectionThrottleFilter will not
affect the core API at all, because it's just a filter. So I removed
Fix Versions field to reduce the number of issues to resolve in
2.0.0-M1, because many people are waiting the first milestone of 2.0.
Of course we will improve ConnectionThrottleFilter in 2.0.0-M2 or M3
probably. Does it make sense?

Mark Webb commented on DIRMINA-389:
-----------------------------------
After performing some more tests, I think I now disagree. I have created a
test case where I make 2 nearly simultaneous connections to a server using
the ConnectionThrottleFilter and they both pass. Seeing that this is our
worst case scenario (malicious client blasting the server), I think we may
need to either:
1. speed up the logic in the filter to prevent thread interleavnig
2. use a synchronized map
I vote for #2 to be safe. In order to support this change, I have made the
clients Map in ConnectionThrottleFilter a synchronized Map using the
Collections class and things work better in my test code. I can post the
test code if you are interested.

What would happen when two clients connect within the same nanosecs? :) Whatever time unit we use, we need an additional counter.

-------------------------------------
We also need to provide a property that limits the number of the clients from the same host.
For now we have a problem with more than one client that connects within the same milliseconds because we are using System.currentTimeMillis(). Adding additional counter will fix it. Therefore, we need some simple bookeeping data structure here.

Cool! A definite case where the ConcurrentHashMap would help though.. It'll allow concurrent modifications, whereas the Synchronized map will become a choke point of its own when a bunch of connection requests come in :)

Maybe this could be solved using an ExpiringHashMap. The expiration time would be the length of time that a host cannot have more than one connection.
