Viewing the Stream Control Transmission Protocol
Viewing the Stream Control Transmission Protocol
The Stream Control Transmission Protocol (SCTP) is a message oriented, reliable transport protocol
with direct support for multihoming that runs on top of Internet Protocol (IPv4/IPv6). Like TCP, SCTP
provides reliable, connection-oriented data delivery with congestion control, path MTU discovery and
message fragmentation.
Its role is similar to the roles of popular protocols such as Transmission Control Protocol (TCP) and User
Datagram Protocol (UDP). It provides some of the same service features of both: it is message-oriented
like UDP and ensures reliable, in-sequence transport of messages with congestion control like TCP.
SCTP offers the following services to the users:
• Acknowledged error-free non-duplicated transfer of user data
• Data fragmentation to conform to discovered path MTU size
• Sequenced delivery of user messages within multiple streams, with an option for order-of-arrival
delivery of individual user messages
QoS DSCP The Quality of Service (QoS) Differentiated Service Code Point (DSCP)
used when sending data packets (of a particular 3GPP QoS class) over the
S1-MME interface. Ths can be any one of the following values:
• af11
• af12
• af13
• af21
• af22
• af23
• af31
• af32
• af33
• af41

• af43
• be
• ef
Crypto Template The name of the crypto template that is used when implementing IP Security
on the S1-MME interface.
