Channels

Within a TIBCO eFTL service, administrators can define several named channels, each of which carries a separate message stream. Administrators can use channels to isolate message streams from one another.

An eFTL application specifies a specific channel name when it connects to a TIBCO eFTL service.

Channel Type

A channel can be configured as an FTL channel or an EMS channel, but not both. The type of the channel denotes this infrastructure: each channel is either an FTL channel or an EMS channel.

If eFTL applications on the channel must communicate with either FTL or EMS applications, then this determines the channel type. If the channel carries messages among only eFTL clients, then the administrator can choose either channel type based on other considerations.

Note: You cannot configure a channel to enable eFTL applications to communicate with both FTL and EMS clients.

If the channel is to carry messages only among eFTL clients, then the administrator can choose either channel type based on other considerations.

Channel Sides

Each channel has an eFTL side, and also has either an FTL side or an EMS side, depending on the channel’s type.

  • FTL Channels
    An FTL channel provides publish-subscribe messaging among eFTL applications, and between eFTL applications and FTL applications.
  • EMS Channels
    An EMS channel provides publish-subscribe messaging among eFTL applications, and between eFTL applications and EMS applications.
