1INTRODUCTION
2
3This folder contains code that implement:
4
51. Dynamic load balancing
6
7OpenSim is allowing many regions to share a region server, but the optimal
8number of regions on each server depends on the load of each region, something
9which may change as time goes on. 3Di is working on a load balancer that
10allows the current load to be monitored and regions to be reassigned without
11requiring the servers to be restarted. To move a region, its state is
12serialized, and a new clone is created on the target server using this
13stream. The old region is then destroyed and the client viewer updated to use
14the new region address.
15
162. Region splitting
17
18Currently each region can hold only a small number of avatars. To allow more
19avatars in each region, 3Di has implemented region splitting, in which several
20copies of a given region can be distributed across the region servers. Each
21sub-region updates a fraction of the avatars, and sends state updates to the
22other sub-regions.
23
24IMPLEMENTATION
25
26The code is organised as follows:
27
28* LoadBalancer: communicates with other region servers and creates/destroys
29regions on command
30* RegionMonitor/MonitorGUI: provides a browser GUI, showing the state of the
31grid, and provides buttons for controlling region movement, splitting, and
32merging.
33* RegionMonitor/ServerPlugin: this is a region server plugin which
34communicates with the load balancer GUI to provide information
35on the identity and status of the regions on the grid
36* RegionProxy: maps messages from a clients to the true location of a region.
37
38USAGE
39
40In order to use these additions the following lines have to be added to
41OpenSim.ini:
42
43proxy_offset = -1000
44proxy_url = http://10.8.1.50:9001
45serialize_dir = /mnt/temp/
46
47If defined, proxy_offset defines how to calculate the true region port, e.g.
48if the XML defines the port as 9000 the actual port is 8000 if proxy_offset
49is -1000. The RegionProxy module will open a port at 9000 which the clients
50can connect to, and route all traffic from there to port 8000. This allows
51the region proxy to run on region server together with regions without
52blocking them by using the same port number.
53
54The proxy location is defined in proxy_url. When splitting, the region state
55is stored on a file in the folder specified in serialize_dir. This has to be
56a shared folder which both region servers involved in the split have access to.
57
583. Monitor GUI
59
60RegionMonitor/MonitorGUI is used to view status of all the managed Region
61servers, and send "Move", "Split", "Merge" commands to a specified Regions
62server.
63
64MonitorGUI is a web-based application. You can access it through a web browser.
65Its back-end is written in perl. (CGI script)
66
67Pre-requierments (CentOS, Fedora)
68
69RPM package "perl-XML-RPC" and relevant packages.
70
71Installation
72
731. Install Apache
742. copy all the files undef "ThirdParty/3Di/RegionMonitor/MonitorGUI/htdocs" to
75"$APACHE_ROOT/htdocs"
763. Configuration in "monitor.cgi"
77 * 10th line, set the value to your "monitor.cgi"'s location.
78 * 11th line, set the value to your Grid server.
79 * 12th line, set your region proxy port number here.
80 (ref. OpenSim.ini::NetWork::http_listener_port)
81* The code also works fine with mod_perl.

56 *
57 * The client interface port may be blocked. While being blocked, all messages from the clients will be
58 * stored in the proxy. Once the interface port is unblocked again, all stored messages will be resent
59 * to the regions. This functionality is used when moving or cloning an region to make sure that no messages
60 * are sent to the region while it is being reconfigured.
61 *
62 * The proxy opens a XmlRpc interface with these public methods:
63 * - AddPort
64 * - AddRegion
65 * - ChangeRegion
66 * - BlockClientMessages
67 * - UnblockClientMessages
