I looked at what information other tools provide:

1) Firebug Network info:
- DNS Lookup: DNS resolution time
- Connecting: Elapsed time required to create a TCP connection.
- Blocking: Elapsed time spent in a browser queue waiting for a network connection. Displayed only in the case where this situation happens.
- Sending: Time needed to send request data to the server.
- Waiting: Waiting for the response (till the first byte is received from the server).
- Receiving: Time necessary to download response body.

FireBug Cache info:
- Last Modified - last time the cache entry was modified
- Last Fetched - last time the cache entry was opened
- Expires - expiration time of the cache entry
- Data Size - cache entry data size
- Fetch Count - number of times the cache entry has been opened
- Device - id for the device that stores this cache entry

2) Page Speed
- DNS - The browser is performing a DNS lookup for this resource
- Wait - The browser is waiting to establish a network (TCP) connection with the web server.
- Connect - The browser is establishing a network (TCP) connection with the web server. This event only appears for new connections; not for connections that are reused.
- Send - The browser has sent the HTTP request. Only GET requests are shown.
- Connected - The browser is waiting for data over the network. The event ends when the browser ends the TCP connection. Resources that show lengthy Connected events may benefit from optimization to reduce payload size, such as compression

3) dynaTrace seems to present subset:
- DNS
- Connect
- Server
- Transfer
