Table 1 describes the fields on the Connection Configuration Sets View, Edit, and Insert pages. Data Input Notes apply only to the Insert and Edit pages; the View page is read-only.
| Field (* indicates required field) | Description | Data Input Notes |
|---|---|---|
| * Connection Configuration Set Name | Unique Name of the Connection Configuration Set. |
Format: case-sensitive string: alphanumeric and underscore (_); must contain at least one alpha and cannot start with a digit Range: 1 - 32 characters |
| SCTP Options | ||
| * Retransmit Initial Timeout (ms) |
Expected average network round-trip time in milliseconds. This is used to initialize the round-trip time value when an association is started but the round-trip time has not yet been measured. The round-trip time is used by SCTP in calculating when to retransmit chunks. |
Format: numeric; milliseconds Range: 10 - 5000 Default: 120 |
| * Retransmit Minimum Timeout (ms) |
Minimum amount of time to wait for an acknowledgment for a message sent. This value prevents the retransmit timeout from becoming too small in networks with a very short round-trip time. |
Format: numeric; milliseconds Range: 10 - 5000 Default: 120 |
| * Retransmit Maximum Timeout (ms) |
Maximum amount of time to wait for an acknowledgment for a message sent. This value places an upper bound on the exponential back-off algorithm used by SCTP for retransmission timing. After this retransmit interval is reached, retransmits will be sent at a constant rate until an ACK is received or the maximum attempts is reached. |
Format: numeric; milliseconds Range: 10 - 10000 Default: 120 |
| * Retransmit Maximum Timeout for INIT (ms) |
Maximum amount of time to wait for an INIT to be acknowledged. This value overrides the Retransmit Maximum Timeout for INITs and is used to bound the initial setup time. A value of 0 indicates that the Retransmit Maximum Timeout will be used for INITs as well. |
Format: numeric; milliseconds Range: 0, 10 - 10000 Default: 120 |
| * Number of Retransmits Triggering Path Failure |
Number of consecutive unsuccessful retransmits that will cause a path of the SCTP association to be marked as failed. This value indicates how many SCTP retransmission attempts should be made to each destination of an SCTP association before marking the destination as failed. This value must be less than the Number of Retransmits Triggering Association Failure value. |
Format: numeric; number of retransmits Range: 1 - 10 Default: 3 |
| * Number of Retransmits Triggering Association Failure |
Number of consecutive retransmits that will cause an SCTP association to be marked as failed. This value indicates how many SCTP retransmission attempts should be made to all destinations for an SCTP association before marking the association as failed. This value should not be greater than the sum of the retransmit attempts for all destinations within the association. |
Format: numeric; number of attempts Range: 1 - 20 Default: 5 |
| * Number of Retransmits Triggering Init Failure |
Number of consecutive retransmits for INIT and COOKIE-ECHO Chunks that will cause an SCTP connection to be marked as failed. This value indicates how many retransmission attempts should be made to the primary SCTP address for INIT and COOKIE-ECHO Chunks before marking the connection as failed. |
Format: numeric; number of attempts Range: 1 - 20 Default: 8 |
| * SACK Delay (ms) |
The number of milliseconds to delay after receiving a DATA Chunk and prior to sending a SACK. A non-zero value for SACK Delay gives the application time to bundle DATA Chunks in the same SCTP datagram with the SACK, thereby reducing the number of packets in the network. Setting SACK Delay to zero disables this delay so that SACKs are sent as quickly as possible. |
Format: numeric; milliseconds Range: 0 - 200 Default: 10 |
| * SCTP Heartbeat Interval (ms) |
The number of milliseconds between sending SCTP HEARTBEAT messages to a Peer. Heartbeat messages are sent only when no user data has been sent for the duration of the Heartbeat Interval. Setting the Heartbeat Interval to 0 disables heartbeating (not recommended). |
Format: numeric; milliseconds Range: 0, 100 - 300000 Default: 500 |
| * Socket Send Buffer Size (bytes) |
Socket send buffer size for outgoing SCTP messages. The send buffer size must be greater than or equal to the product of the bandwidth and the round trip delay for the association. |
Format: numeric; number of bytes Range: 8000 - 5000000 Default: 2000000 |
| * Socket Receive Buffer Size (bytes) |
Socket receive buffer size for incoming SCTP messages. The receive buffer size must be greater than or equal to the product of the bandwidth and the round trip delay for the association. |
Format: numeric; number of bytes Range: 8000 - 5000000 Default: 2000000 |
| * Maximum Burst |
Specifies the maximum burst of packets that can be emitted by this association. |
Format: numeric Range: 1 - 4 Default: 4 |
| * Max Number of Inbound Streams |
Maximum number of inbound SCTP streams supported locally by the SCTP connection. |
Format: numeric; number of streams Range: 1 -16 Default: 8 |
| * Max Number of Outbound Streams |
Maximum number of outbound SCTP streams supported locally by the SCTP connection. |
Format: numeric; number of streams Range: 1 -16 Default: 8 |
| Datagram Bundling Enabled | If checked, datagram bundling is enabled for the SCTP connection. | Format: numeric Range: checked (YES) or unchecked (NO) Default: checked |
| * Maximum Segment Size | The Maximum Size to put in any outgoing SCTP DATA chunk. If a message is larger than this size, it is fragmented by SCTP into the specified size. | Format: numeric field, setting this value to 0 indicates that this is no maximum is segment size.
Range: 0, 64 - 1460 bytes Default: 0 |
| Fragmentation | If checked, a message exceeding the size of the PMTU (Path Max Transmission Unit) is fragmented and reassembled by the peer. | Format: check box
Range: checked (YES) or unchecked (NO) Default: checked |
| Ordered Delivery | If checked, Ordered delivery of the SCTP DATA Chunk is performed. Otherwise, unordered delivery of the SCTP DATA Chunk is performed. | Format: check box

| * Pending Transactions Per Connection | The maximum number of Pending Requests waiting for Answers from the Peer on this connection.
