For even greater capacity, Dedicated Connections can be combined using Link Aggregation Groups. Dedicated Connections are ordered directly from AWS via the Console, CLI or API.

Hosted Connection

Hosted Connections are available in a wide range of capacities, starting at 50M up to 10G. Chunghwa Telecom will provision each Hosted Connection over a network link between the Chunghwa Telecom Device and AWS that is shared by multiple customers. Both Chunghwa Telecom and AWS will limit network traffic on each Hosted Connection to the capacity of each Hosted Connection. AWS ensures that the sum of all capacities of Hosted Connections on a network link between the AWS Direct Connect Partner and AWS is less than or equal to the capacity of that network link. A Hosted Connection will not become active until the customer accepts it via the AWS Console, CLI or API. Each Hosted Connection with a capacity less than or equal to 500M supports one private or public Virtual Interface. Each Hosted Connection with a capacity of greater than or equal to 1G supports one private, public or transit Virtual Interface.
