Viewing the Stream Control Transmission Protocol
Checksum The type of checksum that is used to increase data integrity of the SCTP
packets, which can be any one of the following:
• adler32—the Adler-32 checksum algorithm is used
• crc32—the 32 bit cyclic redundancy check algorithm is used.
Cookie Lifetime The lifetime (in milliseconds) of the SCTP cookie.
Max Association
Retransmission
The maximum number of retransmissions allowed by this template for the
SCTP associations.
Max Incoming Streams The maximum number of incoming SCTP streams.
Max Init
Retransmissions
The maximum number of SCTP initiation retransmissions.
Max MTU Size The maximum size (in bytes) of the Maximum Transmission Unit (MTU) for
SCTP streams.
Min MTU Size The minimum size (in bytes) of the MTU for SCTP streams.
Start Max MTU The starting size (in bytes) of the MTU for SCTP streams.
Max Outgoing Streams The maximum number of outgoing SCTP streams.
Max Retransmissions
Path
The maximum number of retransmissions of the SCTP paths.
RTO Initial The initial time (in milliseconds) for retransmission of SCTP packets.
RTO Max The maximum time (in miliseconds) for retransmission of SCTP packets.
RTO Min The minimum time (in milliseconds) for transmission of SCTP packets.
SACK Frequency The frequency of the Selective Acknowledgement (SACK) of the SCTP
packets.
SACK Period The period (in milliseconds) of selective acknowledgement of the SCTP
packets.
Heart Beat Status Indicates whether the option to send traffic over an alternate path, in case of
a path failure, is enabled.
Note The Heartbeat message is sent to a peer endpoint to probe the
reachability of a particular destination transport address defined in
the present association. If the address is not reachable, the traffic is
sent over an alternate address. If this option is enabled, then the
failover recovery is not even known to the user.
Heart Beat Timer The amount of time (in seconds) to wait before a peer is is considered
unreachable. When a Heartbeat request is sent and if an acknowledgement is
not received before this timer, then subsequent heartbeat requests are not
sent and the peer is considered unreachable.
Bundle Status Indicates whether the data chunks must be bundled into packets before
submitting to the IP. If this option is disabled, then the packets are sent
without bundling.
