# Amazon EC2 instance network bandwidth
<a name="ec2-instance-network-bandwidth"></a>

Instance bandwidth specifications apply to both inbound and outbound traffic for the instance. For example, if an instance specifies up to 10 Gbps of bandwidth, that means it has up to 10 Gbps of bandwidth for inbound traffic and, simultaneously, up to 10 Gbps for outbound traffic. The network bandwidth that's available to an EC2 instance depends on several factors, as follows.

**Multi-flow traffic**  
Bandwidth for multi-flow traffic is limited to 50% of the available bandwidth for traffic that goes through an internet gateway or a [local gateway](https://docs.aws.amazon.com/outposts/latest/userguide/outposts-local-gateways.html) for instances with 32 or more vCPUs, or 5 Gbps, whichever is larger. For instances with fewer than 32 vCPUs, bandwidth is limited to 5 Gbps.

**Single-flow traffic**  
Bandwidth for single-flow traffic is limited to 5 Gbps when instances are not in the same [cluster placement group](placement-strategies.md#placement-groups-cluster). To reduce latency and increase single-flow bandwidth, try one of the following:
+ Use a cluster placement group to achieve up to 10 Gbps bandwidth for instances within the same placement group.
+ Set up multiple paths between two endpoints to achieve higher bandwidth with Multipath TCP (MPTCP).
+ Configure ENA Express for eligible instances within the same Availability Zone to achieve up to 25 Gbps between those instances.

**Note**  
A single-flow is considered a unique 5-tuple TCP or UDP flow. For other protocols following the IP header, such as `GRE` or `IPsec`, the 3 tuple of source IP, destination IP, and next protocol is used to define a flow.

## Available instance bandwidth
<a name="available-instance-bandwidth"></a>

The available network bandwidth of an instance depends on the number of vCPUs that it has. For example, an `m5.8xlarge` instance has 32 vCPUs and 10 Gbps network bandwidth, and an `m5.16xlarge` instance has 64 vCPUs and 20 Gbps network bandwidth. However, instances might not achieve this bandwidth; for example, if they exceed network allowances at the instance level, such as packet per second or number of tracked connections. How much of the available bandwidth the traffic can utilize depends on the number of vCPUs and the destination. For example, an `m5.16xlarge` instance has 64 vCPUs, so traffic to another instance in the Region can utilize the full bandwidth available (20 Gbps). However, traffic that goes through an internet gateway or a [local gateway](https://docs.aws.amazon.com/outposts/latest/userguide/outposts-local-gateways.html) can utilize only 50% of the bandwidth available (10 Gbps).

Typically, instances with 16 vCPUs or fewer (size `4xlarge` and smaller) are documented as having "up to" a specified bandwidth; for example, "up to 10 Gbps". These instances have a baseline bandwidth. To meet additional demand, they can use a network I/O credit mechanism to burst beyond their baseline bandwidth. Instances can use burst bandwidth for a limited time, typically from 5 to 60 minutes, depending on the instance size.

An instance receives the maximum number of network I/O credits at launch. If the instance exhausts its network I/O credits, it returns to its baseline bandwidth. A running instance earns network I/O credits whenever it uses less network bandwidth than its baseline bandwidth. A stopped instance does not earn network I/O credits. Instance burst is on a best effort basis, even when the instance has credits available, as burst bandwidth is a shared resource.

There are separate network I/O credit buckets for inbound and outbound traffic.

**Base and burst network performance**

The *Amazon EC2 Instance Types Guide* describes the network performance for each instance type, plus the baseline network bandwidth available for instances that can use burst bandwidth. For more information, see the following:
+ [Network specifications – General purpose](https://docs.aws.amazon.com/ec2/latest/instancetypes/gp.html#gp_network)
+ [Network specifications – Compute optimized](https://docs.aws.amazon.com/ec2/latest/instancetypes/co.html#co_network)

#### [ AWS CLI ]

You can use the [describe-instance-types](https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instance-types.html) command to display information about an instance type. The following example displays network performance information for all C5 instances.

```
aws ec2 describe-instance-types \
    --filters "Name=instance-type,Values=c5.*" \
    --query "InstanceTypes[].[InstanceType, NetworkInfo.NetworkPerformance, NetworkInfo.NetworkCards[0].BaselineBandwidthInGbps] | sort_by(@,&[2])" \
    --output table
```

The following is example output. If your output is missing the baseline bandwidth, update to the latest version of the AWS CLI.

```

# EC2 instance bandwidth weighting configuration
<a name="configure-bandwidth-weighting"></a>

Some instance types support configurable bandwidth weighting, where you can select baseline bandwidth weighting that favors either network processing or EBS operations. Default settings for baseline bandwidth are determined by your instance type. You can configure the bandwidth weighting during launch, or modify your instance settings with the following weighting preferences:
+ **default** – This option uses the standard bandwidth configuration for your instance type.
+ **vpc-1** – This option increases the baseline bandwidth available for networking and decreases the baseline bandwidth for EBS operations.
+ **ebs-1** – This option increases the baseline bandwidth available for EBS operations, and decreases the baseline bandwidth for networking.

## Bandwidth weighting considerations
<a name="config-bw-considerations"></a>

The following are some considerations that might affect your bandwidth weighting strategy.
+ Setting bandwidth weighting preferences only affects bandwidth specifications. The network packets per second (PPS) and EBS input/output operations per second (IOPS) specifications don't change.
+ The combined bandwidth specification between networking and EBS does not change. When you select a bandwidth weighting configuration, the baseline bandwidth available for the selected option increases, and the baseline bandwidth for the remaining option is reduced by the same absolute amount. For all instances except Flex instances, the available burst bandwidth remains the same for your selected option, and is reduced for the remaining option. For Flex instances up to 4xlarge, burst bandwidth remains unchanged. For Flex instances 8xlarge and larger, burst bandwidth increases by the same amount as the baseline bandwidth.
+ It's important to understand how changes in bandwidth allocation can affect I/O performance for EBS. For EC2 instances that have `vpc-1` configuration (increased networking bandwidth), you might experience lower IOPS for EBS volumes if you reach the EBS bandwidth limit before you've reached the IOPS limit. This is more noticeable with larger I/O sizes.

  For example, on an instance type that normally supports 240,000 IOPS with 16 KiB I/O size, if you select `vpc-1` weighting, that might reduce the achievable IOPS due to the adjusted EBS baseline bandwidth limit.

  When planning your workload, consider your I/O size and patterns. Smaller I/O sizes are less likely to be affected by bandwidth limitations, while larger I/O sizes or sequential workloads might see more impact from bandwidth changes. Always test your specific workload to ensure optimal performance with your chosen configuration.
+ The networking multi-flow bandwidth specification for traffic that goes through an internet gateway or a local gateway is adjusted to 50% of the baseline bandwidth of the configured option or 5 Gbps, where applicable. For more information, see [Amazon EC2 instance network bandwidth](ec2-instance-network-bandwidth.md).

  The following example is based on an instance type that has a default baseline bandwidth of 40 Gbps, and a default border bandwidth of 20 Gbps. If you choose `vpc-1` bandwidth weighting for this instance, the weighted baseline bandwidth changes to 50 Gbps, and the border bandwidth changes to 25 Gbps.
+ This feature is available in all commercial regions, aligned with EC2 instance availablilty and support.
+ This feature adds no additional cost to your EC2 instance.

## Monitor instance bandwidth
<a name="monitor-instance-bandwidth"></a>

You can use CloudWatch metrics to monitor instance network bandwidth and the packets sent and received. You can use the network performance metrics provided by the Elastic Network Adapter (ENA) driver to monitor when traffic exceeds the network allowances that Amazon EC2 defines at the instance level.

You can configure whether Amazon EC2 sends metric data for the instance to CloudWatch using one-minute periods or five-minute periods. It is possible that the network performance metrics would show that an allowance was exceeded and packets were dropped while the CloudWatch instance metrics do not. This can happen when the instance has a short spike in demand for network resources (known as a microburst), but the CloudWatch metrics are not granular enough to reflect these microsecond spikes.
