class SctpProfile

Transport
SctpProfile

The SctpProfile defines the configuration that controls the behaviour of an SCTP Association.
In order to reconfigure an attribute of this MO, the associated MOs representing controllers need to be locked (i.e. Sbg for vBGF and MrfH248Interface for vMRF).


This MO is created by the system.

Attributes
AlphaIndex
alphaIndex = ALPHA_1_8TH
This is the RTO.
Alpha value when expressed in right shifts and is used in RTO calculations.


Specification: RFC 4960, section 6.3.1
uint8
assocMaxRtx = 8 { 1..20 }
Maximum number of consecutive retransmissions to a peer.
If the number of retransmissions exceeds this value, endpoint considers that the peer is unreachable and closes the association.


Specification: RFC 4960, section 6.3.1
BetaIndex
betaIndex = BETA_1_4TH
This is the RTO.
Beta value when expressed in right shifts and is used in RTO calculations.


Specification: RFC 4960, section 6.3.1
uint8
cookieLife = 60 { 1..180 }
This is the maximum lifespan of the Cookie sent in an INIT ACK chunk.

Unit: 1 s
Specification: RFC 4960, section 5.1.3
uint8
dscp = 40 { 0..63 }
The DSCP value.
boolean
enablePathMtuDiscovery = false
Automatic discovery of SCTP Maximum Transmission Unit (MTU) size based on ICMP.
false (default) : Disable automatic discovery of SCTP MTU size towards the controller node. The used SCTP MTU size value is based on the 'maxSctpPduSize' attribute.
true : Enable automatic discovery of SCTP MTU size towards the controller node. The initial value and upper limit for the SCTP MTU size value is based on the 'maxSctpPduSize' attribute.
uint32
heartbeatInterval = 1000 { 10..180000 }
This is the interval when a HEARTBEAT chunk is sent to a destination transport address.
It is to monitor the reachability of an idle destination transport address.


Unit: 1 ms
Specification: RFC 4960, section 8.3
uint32
initRto = 300 { 10..120000 }
This is the initial value of RTO (retransmission timeout) that is used in RTO calculations.

Unit: 1 ms
Specification: RFC 4960, section 6.3.1.
uint16
maxBurst = 4 { 1..16384 }
Maximum number of new data packets that can be sent in a burst.

Specification: RFC 4960, section 6.1
uint8
maxInitRt = 8 { 1..16 }
Maximum number of times an INIT chunk or a COOKIE ECHO chunk is retransmitted.
If the number of retransmissions exceeds this value, endpoint aborts the initialization process and closes the association.
uint32
maxRto = 400 { 11..120000 }
This is the maximum value of RTO (retransmission timeout) that is used in RTO calculations.

Unit: 1 ms
Specification: RFC 4960, section 6.3.1
uint16
maxSctpPduSize = 1432 { 480..1480 }
The maximum size of the SCTP PDU towards the controller node.
The maximum number of bytes in an SCTP PDU that can be transferred in a single unit over a specific path in an IP network. If an SCTP PDU exceeds the configured value it is segmented into multiple IP packets. Note that the value does not include the IP header. When 'enablePathMtuDiscovery' is set, the upper limit of the discovered MTU is based on the value of this attribute.
uint16
minRto = 100 { 10..5000 }
This is the minimum value of RTO (retransmission timeout) that is used in RTO calculations.

Unit: 1 ms
Specification: RFC 4960, section 6.3.1
uint8
pathMaxRtx = 4 { 1..20 }
Maximum number of consecutive retransmissions over a destination transport address of a peer.
If the number of retransmissions exceeds this value, peer endpoint is marked as inactive.
uint8
primaryPathMaxRtx = 0 { 0..20 }
Maximum value of the error counter of the current primary path in case of enabled PPA.
In case of enabled Primary Path Avoidance(PPA), if the error counter of the primary path exceeds this value, SCTP will chooses another current primary path.
uint16
sackTimer = 40 { 0..500 }
Time delay for sending the Selective Acknowledgement (SACK).
Time is measured from reception of the DATA chunk to sending of the SACK chunk.


Unit: 1 ms

sctpProfileId
Value component of the RDN.
