Rocks provides an user-level package for reliable and mobile network connections.
Rocks protect sockets-based applications from network failures, particularly failures common to mobile computing, including:
.Link failures (e.g., unexpected modem disconnection);
.IP address changes (e.g., laptop movement, DHCP lease expiry);
.Extended periods of disconnection (e.g., laptop suspension).
Rock-enabled programs continue to run after any of these events; their broken connections recover automatically, without loss of in-flight data, when connectivity returns.
Rocks work transparently with most applications, including SSH clients, X-windows applications, and network service daemons.
Here are some key features of "Rocks":
· Reliable: Rocks detect connection failures within seconds and reconnect automatically when connectivity is restored. Reconnection succeeds even when one end of the connection obtains a new IP address.
· Safe: Rocks recover lost in-flight data no matter when failures occur, safely interoperate with ordinary sockets, and authenticate resumed connections.
· User level: You can install and use rocks as an ordinary user. They do not require any kernel modifications.
· Transparent: You can use rocks with existing programs without re-programming, re-compiling, or re-linking.
· Easy to use: Rocks come with simple command-line tools for enabling rocks in ordinary programs.
