Quotas and limits

The following sections describe quotas and limits for Cloud Interconnect. To change a quota, simply request additional quota using the Cloud Console. Limits cannot generally be increased unless specifically noted.

Quotas

This table highlights important quotas for each project. See the quotas page for other quotas.

Item Quota Notes
Interconnects Quota This is the number of interconnects per project. Interconnects are not associated with regions or VPC networks.
Interconnect bandwidth per project Calculated automatically This quota represents the total interconnect bandwidth for the project, calculated by adding up the bandwidths of each interconnect it contains.

The bandwidth of each interconnect is calculated by multiplying the capacities of its circuits (either 10 Gbps or 100Gbps) by the number of circuits in the interconnect. For example, an interconnect consisting of four 10 Gbps circuits has 40 Gbps of bandwidth. If you have two such interconnects in your project, this quota is automatically set to 80 Gbps.
Interconnect attachments Quota This quota represents the number of interconnect attachments (VLANs) that you can configure in each region for your project. Regardless of this quota, you are also limited to a total of 16 interconnect attachments per interconnect. If you require additional attachments per interconnect, refer to Maximum number of interconnect attachments (VLANs) that can be associated with a single interconnect in limits, below.
Interconnect attachments total Mbps Quota This quota represents the maximum bandwidth capacity of all interconnect attachments in a given region for a given project, irrespective of their relationship with interconnects. In addition to this quota, the limits described in the next table apply.
Cloud Routers Quotas This quota represents the number of Cloud Routers you can create within your project, in any network and region. Networks also have a limit on the number of Cloud Routers in any given region. See Cloud Router quotas and limits for more details.

Limits

The following limits apply to interconnects and interconnect attachments. Unless otherwise stated, these limits cannot be increased.

Item Limit Notes
Maximum number of physical circuits per interconnect 8 x 10 Gbps (80 Gbps) circuits or
2 x 100 Gbps (200 Gbps) circuits
An interconnect is a logical connection to Google, made up of one or more physical circuits. You can request one of the following circuit choices:
  • Up to 2 x 100 Gbps (200 Gbps) circuits.
  • 10 Gbps increments up to eight circuits (80 Gbps) to increase the maximum total bandwidth of all interconnect attachments that use the interconnect to 80 Gbps.
    To determine the bandwidth, multiply the number of physical circuits by the bandwidth per circuit (10 Gbps).
Maximum number of interconnect attachments (VLANs) that can be associated with a single interconnect 16 Each interconnect supports no more than 16 interconnect attachments (VLANs), even if you would otherwise have quota to create more interconnect attachments.
Maximum bandwidth per interconnect attachment Capacities from 50 Mbps to 50 Gbps The maximum possible bandwidth per interconnect attachment depends on the bandwidth capacity you order. See the Pricing page for capacities. For Partner Interconnect, not all partners offer all capacities.

The throughput of individual flows on an interconnect attachment is limited, as described below. To achieve maximum throughput, you must use multiple five-tuple flows (for example: 10+) with packet sizes within the MTU of the interconnect attachment.
Maximum total packet rate per interconnect attachment (VLAN) This rate varies according to the attachment's capacity:
  • The maximum rate for a 50 Gbps interconnect attachment (VLAN) is 6.25M packets per second (pps).
  • The maximum rate for a 10 Gbps interconnect attachment (VLAN) is 1.25M packets per second (pps)
This represents the maximum packet rate for the entire interconnect attachment (VLAN).
Maximum bandwidth per traffic flow on an interconnect attachment 3 Gbps. Even if you configure your attachment above 3 Gbps, your per-flow capacity is capped at 3 Gbps. A traffic flow is identified by either a five-tuple hash for non-fragmented packets or a three-tuple hash for fragmented packets.
  • A five tuple hash consists of a protocol, source IP address, source port, destination IP address, and destination port.
  • A three-tuple hash consists of a protocol, source IP address, and destination IP address.
The following cases describe where the maximum bandwidth is lower than 3 Gbps:
  • If the bandwidth capacity of your interconnect attachment itself is less than 3 Gbps, then the bandwidth per traffic flow is limited by the bandwidth of the interconnect attachment.
  • If you reach the maximum packet rate per traffic flow, described next.
Maximum packet rate per traffic flow on an interconnect attachment 250,000 packets per second This number represents the maximum rate of packets per traffic flow, as identified by a five-tuple hash for non-fragmented packets and by a three-tuple hash for fragmented packets, as described in the previous section.
Maximum Transmission Unit 1440 bytes The size of the largest IP packet that can be transmitted over an interconnect attachment.
Maximum lifetime of (Partner) interconnect attachment pairing key 28 days The maximum amount of time that can pass between generating a (partner) interconnect attachment pairing key and successful attachment provisioning by the partner. If a pairing key is no longer valid, you just delete and recreate a new pairing key for the partner interconnect provider to use.
Cloud Router limits Because Dedicated Interconnect and Partner Interconnect require Cloud Router, all of the Cloud Router quotas and limits apply. There are limits on the maximum number of learned custom dynamic routes and on the number of advertised routes. Carefully review the Cloud Router Quotas and limits page for more information.

Descripción general

Cloud Interconnect aplica cuotas sobre el uso de recursos por diversos motivos. Por ejemplo, las cuotas protegen a la comunidad de usuarios Google Cloud mediante la prevención de los aumentos imprevistos en el uso. Las cuotas también ayudan a que los usuarios que exploran Google Cloud con el nivel gratuito permanezcan dentro de su prueba.

Todos los proyectos comienzan con las mismas cuotas, que puedes cambiar mediante la solicitud de cuotas adicionales. Algunas cuotas pueden aumentar de forma automática en función del uso que haces del producto.

Permisos

Para visualizar las cuotas o solicitar aumentos de estas, los miembros de IAM deben tener alguna de las siguientes funciones.

Tarea Función requerida
Consultar cuotas para un proyecto Propietario o editor de un proyecto o visualizador de cuotas
Modificar cuotas, solicitar cuota adicional Propietario o editor del proyecto, administrador de cuota o una función personalizada con el permiso serviceusage.quotas.update

Comprueba la cuota

En Cloud Console, ve a la página Cuotas.

Con la herramienta de línea de comandos de gcloud, ejecuta el siguiente comando para comprobar tus cuotas. Reemplaza [PROJECT_ID] por el ID de tu proyecto.

        gcloud compute project-info describe --project [PROJECT_ID]

Para comprobar la cuota usada en una región, ejecuta lo siguiente:

        gcloud compute regions describe example-region

Errores cuando excedes la cuota

Si excedes una cuota con un comando gcloud, gcloud muestra un mensaje de error quota exceeded y el código de salida 1.

Si excedes una cuota con una solicitud a la API, Google Cloud muestra el siguiente código de estado HTTP: HTTP 413 Request Entity Too Large.

Solicita cuota adicional

Solicita cuota adicional de la página Cuotas en Cloud Console. Las solicitudes de cuotas toman entre 24 y 48 horas en procesarse.

  1. Ve a la página Cuotas.

    Ir a la página Cuotas

  2. En la página Cuotas, selecciona las cuotas que deseas cambiar.
  3. Haz clic en el botón Editar cuotas en la parte superior de la página.
  4. Llena los campos con tu nombre, correo electrónico y número de teléfono, y haz clic en Siguiente.
  5. Llena la solicitud de cuota y presiona Siguiente.
  6. Envía la solicitud.

Disponibilidad de recursos

Cada cuota representa la cantidad máxima de un tipo particular de recurso que puedes crear, siempre y cuando el recurso esté disponible. Es importante tener en cuenta que las cuotas no garantizan la disponibilidad del recurso. Incluso si tienes cuotas disponibles, no podrás crear un recurso nuevo si no está disponible. Por ejemplo, podrías tener una cuota suficiente para crear una dirección IP externa regional nueva en la región us-central1, pero eso no sería posible si no hubiera direcciones IP externas disponibles en esa región. La disponibilidad zonal de recursos también puede afectar tu capacidad para crear un recurso nuevo.

Las situaciones en las que los recursos no están disponibles en toda una región son poco frecuentes; sin embargo, los recursos dentro de una zona pueden agotarse cada tanto, por lo general, sin impacto alguno en el ANS para el tipo de recurso. A fin de obtener más información, revisa el Acuerdo de Nivel de Servicio (ANS) para el recurso.
