CfnNetworkInterfaceAttachmentPropsMixin

class aws_cdk.mixins_preview.aws_ec2.mixins.CfnNetworkInterfaceAttachmentPropsMixin(props, *, strategy=None)

Bases: Mixin

Attaches an elastic network interface (ENI) to an Amazon EC2 instance.

You can use this resource type to attach additional network interfaces to an instance without interruption.

CloudformationResource:: AWS::EC2::NetworkInterfaceAttachment
Mixin:: true
ExampleMetadata:: fixture=_generated

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
from aws_cdk.mixins_preview import mixins

    ),
    instance_id="instanceId",
    network_interface_id="networkInterfaceId"
),
    strategy=mixins.PropertyMergeStrategy.OVERRIDE
)

Create a mixin to apply properties to AWS::EC2::NetworkInterfaceAttachment.

Parameters:

props (Union[CfnNetworkInterfaceAttachmentMixinProps, Dict[str, Any]]) – L1 properties to apply.
strategy (Optional[PropertyMergeStrategy]) – (experimental) Strategy for merging nested properties. Default: - PropertyMergeStrategy.MERGE

Methods

Parameters:: construct (IConstruct)
Return type:: IConstruct

supports(construct)

Check if this mixin supports the given construct.

Parameters:: construct (IConstruct)
Return type:: bool

Attributes

Static Methods

classmethod is_mixin(x)

(experimental) Checks if x is a Mixin.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Mixin.
Stability:: experimental

ENA Express uses AWS Scalable Reliable Datagram (SRD) technology to increase the maximum bandwidth used per stream and minimize tail latency of network traffic between EC2 instances.

With ENA Express, you can communicate between two EC2 instances in the same subnet within the same account, or in different accounts. Both sending and receiving instances must have ENA Express enabled.

To improve the reliability of network packet delivery, ENA Express reorders network packets on the receiving end by default. However, some UDP-based applications are designed to handle network packets that are out of order to reduce the overhead for packet delivery at the network layer. When ENA Express is enabled, you can specify whether UDP network traffic uses it.

Parameters:

ena_srd_enabled (Union[bool, IResolvable, None]) – Indicates whether ENA Express is enabled for the network interface.
ena_srd_udp_specification (Union[IResolvable, EnaSrdUdpSpecificationProperty, Dict[str, Any], None]) – Configures ENA Express for UDP network traffic.

EnaSrdUdpSpecificationProperty

class CfnNetworkInterfaceAttachmentPropsMixin.EnaSrdUdpSpecificationProperty(*, ena_srd_udp_enabled=None)

Bases: object

ENA Express is compatible with both TCP and UDP transport protocols.

When it’s enabled, TCP traffic automatically uses it. However, some UDP-based applications are designed to handle network packets that are out of order, without a need for retransmission, such as live video broadcasting or other near-real-time applications. For UDP traffic, you can specify whether to use ENA Express, based on your application environment needs.

Parameters:: ena_srd_udp_enabled (Union[bool, IResolvable, None]) – Indicates whether UDP traffic to and from the instance uses ENA Express. To specify this setting, you must first enable ENA Express.
