# airviz - server
EthNewYork hack, websocket server
## Server
Hub: maintains clients and routes data pushes to each client
Client: listens for messages from user, gets pushes from hub.
DataReqHandler: filters pushes by time range, batches pushes into requests. Handles requests together with user requests. Only acts on latest request.
Topic: `byte`
Time index: `uint32`
DAG: dag structure, items per layer
Node: dag item, *points* to parent node
Box: index, parent key, self key, value
Status: client status, count (depth) of items at each time index. Offset by possibly different time index than server, window is of constant length.
Update atom: only new items are send to the client, i.e. the `[old_depth:new_depth]` range. One item per message.
## Messages:
### request
```
4 bytes | 4 bytes | 4 bytes per index
topic | time index | depth per index, starting from time index, defines window of request.
```
### response: update item
```
4 bytes | 4 bytes | 4 bytes | 20 bytes | 32 bytes | 32 bytes | n bytes
topic | time index | depth | unused | parent key | self key | SSZ serialized data
```
