Pipeline transport

District heating District heating or teleheating systems consist of a network of insulated feed and return pipes which transport heated water, pressurized hot wateror sometimes steam to the customer. While steam is hottest and may be used in industrial processes due to its higher temperature, it is less efficient to produce and transport due to greater heat losses. Heat transfer oils are generally not used for economic and ecological reasons.

In this article Summary: Learn about mail flow and the transport pipeline in Exchange In Exchange Servermail flow occurs through the transport pipeline. The transport pipeline is a collection of services, connections, components, and Pipeline transport that work together to route all messages to the categorizer in the Transport service on an Exchange Mailbox server inside the organization.

For information about how to configure mail flow in a new Exchange organization, see Configure mail flow and client access. Understanding the transport pipeline The transport pipeline consists of the following services: Front End Transport service on Mailbox servers: This service acts as a stateless proxy for all inbound and optionally outbound external SMTP traffic for the Exchange organization.

Transport service on Mailbox servers: This service is virtually identical to the Hub Transport server role in Exchange Server The Transport service handles all SMTP mail flow for the organization, performs message categorization, and performs message content inspection. Unlike Exchangethe Transport service never communicates directly with mailbox databases.

That task is now handled by the Mailbox Transport service. The Transport service routes messages among the Mailbox Transport service, the Transport service, the Front End Transport service, and depending on your configuration the Transport service on Edge Transport servers. The Transport service on Mailbox servers is described in more detail later in this topic.

Mailbox Transport service on Mailbox servers: This service consists of two separate services: Mailbox Transport Submission service: This service connects to the local mailbox database using an Exchange remote procedure call RPC to retrieve messages.

The Mailbox Transport Submission service has access to the same routing topology information as the Transport service. Mailbox Transport Delivery service: This service receives SMTP messages from the Transport service on the local Mailbox server or on other Mailbox servers and connects to the local mailbox database using RPC to deliver the messages.

Transport service on Edge Transport servers: This service is very similar to the Transport service on Mailbox servers. If you have an Edge Transport server installed in the perimeter network, all mail coming from the Internet or going to the Internet flows through the Transport service Edge Transport server.

This service is described in more detail later in this topic. The following diagram shows the relationships among the components in the Exchange transport pipeline.

Note Although the diagrams in this topic show the components on a single Exchange server, communication also occurs between those components on different Exchange servers. The only communication that always occurs on the local Exchange server is between the Mailbox Transport service and the local mailbox database.

Overview of the transport pipeline in Exchange How messages from external senders enter the transport pipeline The way messages from outside the Exchange organization enter the transport pipeline depends on whether you have a subscribed Edge Transport server deployed in your perimeter network.

Inbound mail flow no Edge Transport servers The following diagram and list describe inbound mail flow with only Exchange Mailbox servers.

While gas collection and transmission lines are made of steel, most distribution lines. The U.S. natural gas pipeline network is a highly integrated transmission and distribution grid that can transport natural gas to and from nearly any location in the lower 48 states.

It consists of more than natural gas pipeline systems and , miles of interstate and intrastate transmission pipelines.
