public class SapConstants

extends java.lang.Object

Various constants used in ServerSap, ConnectionSap and sub-classes.

Field Summary

static boolean	ACK_EVERY_PACKET ack every packet??
static int	DEFAULT_BUF_SIZE default input/output buffer size (64000).
static int	DEFAULT_CONNECTION_TIMEOUT_MS Connection timeout, ms (not configurable for tcp) (30000)
static int	DEFAULT_KEEP_ALIVE_TIME_MS Default keep-alive message send interval, milliseconds (5000)
static int	DEFAULT_LONG_CONNECTION_TIMEOUT_MS Alternative connection timeout for 'long' timeouts, e.g.
static int	DEFAULT_PROBING_INTERVAL_MS Default channel probing time, ms (UDP?!)
static int	DEFAULT_RECV_TIMEOUT_MS Default receive timeout (0); 0=blocking
static int	DEFAULT_SLOW_RESPONSE_TIME_MS Default slow response time, milliseconds (2000)
static int	DEFAULT_SLOW_RESPONSE_TIME_MS_TCP TCP slow response time, ms (7000).
static int	DEFAULT_SLOW_RESPONSE_TIME_MS_UDP UDP slow response time, ms (2000).

Field Detail

DEFAULT_BUF_SIZE

public static final int DEFAULT_BUF_SIZE

default input/output buffer size (64000). a small buffer will give better local effective suppression of unreliable update cascades

Constant Field Values

DEFAULT_RECV_TIMEOUT_MS

public static final int DEFAULT_RECV_TIMEOUT_MS

Default receive timeout (0); 0=blocking

Constant Field Values

DEFAULT_KEEP_ALIVE_TIME_MS

public static final int DEFAULT_KEEP_ALIVE_TIME_MS

Default keep-alive message send interval, milliseconds (5000)

Constant Field Values

DEFAULT_SLOW_RESPONSE_TIME_MS

public static final int DEFAULT_SLOW_RESPONSE_TIME_MS

Default slow response time, milliseconds (2000)

See Also:

Constant Field Values

DEFAULT_SLOW_RESPONSE_TIME_MS_TCP

public static final int DEFAULT_SLOW_RESPONSE_TIME_MS_TCP

TCP slow response time, ms (7000). TCP does not ACK by default, so waiting for keep alives in worst case

See Also:

Constant Field Values

DEFAULT_SLOW_RESPONSE_TIME_MS_UDP

public static final int DEFAULT_SLOW_RESPONSE_TIME_MS_UDP

UDP slow response time, ms (2000). UDP should ACK

See Also:

Constant Field Values

DEFAULT_PROBING_INTERVAL_MS

public static final int DEFAULT_PROBING_INTERVAL_MS

Default channel probing time, ms (UDP?!) (2000)

See Also:

Constant Field Values

DEFAULT_CONNECTION_TIMEOUT_MS

public static final int DEFAULT_CONNECTION_TIMEOUT_MS

Connection timeout, ms (not configurable for tcp) (30000)

See Also:

Constant Field Values

DEFAULT_LONG_CONNECTION_TIMEOUT_MS

public static final int DEFAULT_LONG_CONNECTION_TIMEOUT_MS

Alternative connection timeout for 'long' timeouts, e.g. intermittantly connected clients, ms (1800000). VERY LONG VALUE FOR WIRE EXPERIMENTS - SHOULD BE SET BETTER/DYNAMICALLY!

See Also:

Constant Field Values

ACK_EVERY_PACKET

public static final boolean ACK_EVERY_PACKET

ack every packet?? (JCP only, I think). tentative workaround for 0.5 second (retrans.) stall when flow control bites
