# Transport
<a name="API_Transport"></a>

 Attributes related to the transport stream that are used in a source or output.

## Contents
<a name="API_Transport_Contents"></a>

 ** protocol **   <a name="mediaconnect-Type-Transport-protocol"></a>
 The protocol that is used by the source or output.  
 AWS Elemental MediaConnect no longer supports the Fujitsu QoS protocol. This reference is maintained for legacy purposes only.
Type: String  
Valid Values: `zixi-push | rtp-fec | rtp | zixi-pull | rist | st2110-jpegxs | cdi | srt-listener | srt-caller | fujitsu-qos | udp | ndi-speed-hq`   
Required: Yes

 ** cidrAllowList **   <a name="mediaconnect-Type-Transport-cidrAllowList"></a>
 The range of IP addresses that should be allowed to initiate output requests to this flow. These IP addresses should be in the form of a Classless Inter-Domain Routing (CIDR) block; for example, 10.0.0.0/16  
Type: Array of strings  
Required: No

 ** maxBitrate **   <a name="mediaconnect-Type-Transport-maxBitrate"></a>
 The smoothing max bitrate (in bps) for RIST, RTP, and RTP-FEC streams.  
Type: Integer  
Required: No

 ** maxLatency **   <a name="mediaconnect-Type-Transport-maxLatency"></a>
 The maximum latency in milliseconds. This parameter applies only to RIST-based and Zixi-based streams.  
Type: Integer  
Required: No

 ** maxSyncBuffer **   <a name="mediaconnect-Type-Transport-maxSyncBuffer"></a>
 The size of the buffer (in milliseconds) to use to sync incoming source data.  
Type: Integer  
Required: No

 ** minLatency **   <a name="mediaconnect-Type-Transport-minLatency"></a>
 The minimum latency in milliseconds for SRT-based streams. In streams that use the SRT protocol, this value that you set on your MediaConnect source or output represents the minimal potential latency of that connection. The latency of the stream is set to the highest number between the sender’s minimum latency and the receiver’s minimum latency.  
Type: Integer  
Required: No

 ** ndiProgramName **   <a name="mediaconnect-Type-Transport-ndiProgramName"></a>
A suffix for the name of the NDI® sender that the flow creates. If a custom name isn't specified, MediaConnect uses the output name.   
Type: String  
Required: No

 ** ndiSourceSettings **   <a name="mediaconnect-Type-Transport-ndiSourceSettings"></a>
 The settings for the NDI source. This includes the exact name of the upstream NDI sender that you want to connect to your source.   
Type: [NdiSourceSettings](API_NdiSourceSettings.md) object  
Required: No

 ** ndiSpeedHqQuality **   <a name="mediaconnect-Type-Transport-ndiSpeedHqQuality"></a>
A quality setting for the NDI Speed HQ encoder.   
Type: Integer  
Required: No

 ** remoteId **   <a name="mediaconnect-Type-Transport-remoteId"></a>
 The remote ID for the Zixi-pull stream.  
Type: String  
Required: No

 ** senderControlPort **   <a name="mediaconnect-Type-Transport-senderControlPort"></a>
 The port that the flow uses to send outbound requests to initiate connection with the sender.  
Type: Integer  
Required: No

 ** senderIpAddress **   <a name="mediaconnect-Type-Transport-senderIpAddress"></a>
 The IP address that the flow communicates with to initiate connection with the sender.  
Type: String  
Required: No

 ** smoothingLatency **   <a name="mediaconnect-Type-Transport-smoothingLatency"></a>
 The smoothing latency in milliseconds for RIST, RTP, and RTP-FEC streams.  
Type: Integer  
Required: No

 ** sourceListenerAddress **   <a name="mediaconnect-Type-Transport-sourceListenerAddress"></a>
 Source IP or domain name for SRT-caller protocol.  
Type: String  
Required: No

 ** sourceListenerPort **   <a name="mediaconnect-Type-Transport-sourceListenerPort"></a>
 Source port for SRT-caller protocol.  
Type: Integer  
Required: No

 ** streamId **   <a name="mediaconnect-Type-Transport-streamId"></a>
 The stream ID that you want to use for this transport. This parameter applies only to Zixi and SRT caller-based streams.  
Type: String  
Required: No
