Inception Draft | February 1, 2006 | First Draft, To be refined in Elaboration as necessary | Team SPEW |
We envision a debugging toolkit that allows us to figure out how a peer-to-peer network is actually behaving; specifically, a toolkit that allows for visualizing how messages are routed in the network. In particular, our debugging toolkit would allow us to see graphically how an individual message gets routed through the network; which regions of the network are experiencing heavy or light traffic; which regions of the network are generating heavy or light traffic. We will be extending an existing toolkit called ODIN, which would have to be modified in order to accomplish the goal of creating a useful tool for anyone developing a peer-to-peer network.
Peer-to-Peer systems are difficult to visualize and difficult to understand in regard to how they are behaving/operating. Current graph layout tools are too expensive and too hard to use to visualize Peer-to-Peer networks. Based on the current options for visualizing Peer-to-Peer networks, the opportunity of creating debugging toolkit for understanding how Peer-to-Peer networks operate, is very promising.
Peer-to-peer networks are moving beyond music filesharing and becoming popular platforms for building a variety of distributed applications. Although many Peer-to-Peer systems are being built, it is difficult to get a good understanding of how they actually operate: because the networks are so big (thousands, tens of thousands, hundreds of thousands of peers) it is difficult to observe the system and determine what is actually happening.
We would like to build the debugging toolkit, ODIN, that allows us to figure out how a peer-to-peer network is actually behaving. ODIN will visualize how messages are be routed in the network. In particular, ODIN will graphically show how an individual message gets routed through the network; which regions of the network are experiencing heavy or light traffic; which regions of the network are generating heavy or light traffic.
The target audience is users who do research on Peer-toPeer networks or owners/administrators of Peer-to-Peer networks.
Stakeholders that are not users, also known as non-users, would cover individuals that use Peer-to-Peer networks.
Potential users are concerned about security and privacy.
Administrators of Peer-to-Peer networks are concern about how their Peer-to-Peer network functions.
High-Level Goal | Priority | Problems and Concerns | Current Solutions |
Visualize network | High | May be difficult to please everyone's expectation of how viewing the network should be. | Continue with existing methods. |
Simulate network correctly | High | Not possible to test all potential situations. | Continue with existing methods. |
Ability to debug | High | How exactly the way to perform debugging according to the Stakeholder may be difficult. | Continue with existing methods. |
Easy of use | High | Every Stakeholder thinks differently. What seems easy for one, may be difficult for another. | Continue with existing methods. |
Extensibility | Medium | Next group of programmers of ODIN need to be able to understand existing code. | N/A |
Find problems using ODIN for their network.
Diagnostic routing of message and identify overbounded messages.
Still image for presentation of ODIN.
Linux environment for first user and future users.

Supporting Feature | Stakeholder Benefit |
Visualize network | Can see how exactly his/her network is performing. |
Simulate network correctly | Can simulate their network correctly without running it in real time. |
Ability to debug | Can debug their network with the help of ODIN. |
Easy of use | Can use ODIN easily without problems. |
Producible without cost.
ODIN has not license and currently no install because it is for the sole purpose of its first user (Dr. Cooper).
For the CS 4911 Design Project (Spring 2006), a Visualizing Peer-to-Peer network debugging tool named ODIN will be created which is easy to use for the purpose of debugging Peer-to-Peer networks, figuring out how a Peer-to-Peer network actually behaves, graphically viewing how an individual message gets routed through the network, which regions of the network are experiencing heavy or light traffic and which regions of the network are generating heavy or light traffic. The following is a list of the major pieces of functionality that ODIN will provide:
· Run simulation and get output.
· Still of test run and animation (node & link).
· Ability to play animation, and speed it up.
· Graph should layout itself for easily viewing the Peer-to-Peer network.
· Layout (algorithm) for graph be seen.
· Ability to scroll and view graph.
· Documentation of ODIN.
