Routers

Defined routers are listed.


Field	Description
Name	The name of the router.
Edit Button	Edits this router.
Delete Button	Removes this router.
Port	The port the router is listening on for non-HTTP traffic such as legacy socket connections (connection dispatchers) and Grid client protocol.
Host	The host that the router is configured to run on. It is possible to configure a router so that it automatically runs on all hosts in the grid by choosing <all hosts>. This can be useful if configuring a load balancer to distribute the load of client connections amongst all the hosts in the grid for either resilience or load balancing.
External Address	Optional external address (FQDN or IP Address). If undefined, the router listens on the same address as the grid agent is using on this host. If the host has several network interfaces, it is possible to select a different one here.
Encryption & Ciphers	It is possible to enable SSL encryption for this port. For more information on what these settings mean, see "To configure SSL for grid proxy clients" in the Infor ION Grid Security Administration Guide.
HTTP Port	The HTTP port of the router if defined. The HTTP port serves web applications and web services.
HTTP WWW Authentication Methods	The router configuration dialog has settings for WWW authentication methods . For more information on what these settings mean, see "Configuring Router WWW Authentication Methods" in the Infor ION Grid Security Administration Guide.
HTTPS Port	The HTTPS port of the router if defined. The HTTPS port serves web applications and web services.
HTTPS Authentication Type	It is possible to configure the authentication type for the HTTPS connections on this port.
HTTPS Encryption & Ciphers	It is possible to enable SSL encryption for this port. For more information on what these settings mean, see "To configure SSL for grid HTTP clients" in the Infor ION Grid Security Administration Guide.
HTTPS WWW Authentication Methods	The router configuration dialog has settings for WWW authentication methods . For more information on what these settings mean, see "Configuring Router WWW Authentication Methods" in the Infor ION Grid Security Administration Guide.

Editing and adding routers

Routers may be added or existing routers may be reconfigured. Client applications may connect to any router as long as it is exposing the right type of port (for example, HTTP) and that port is exposed on a network interface that is accessible from the client.

One reason for adding a new router is that you want to bind it to another network interface compared to the existing routers, or you wish to add additional router(s) to distribute the load or scale-out to additional host(s) for resilience. The external address property of the router is used for this. See above. Another reason for adding a router is to achieve high availability. By having two routers that serve the same types of ports but on different hosts, you still have a way for clients to connect to the grid even if one of the routers fails. To make this fully transparent to the clients, some form of network load balancer in front of the routers may be needed.

To add a router, click the Add Router link. Edit a router by clicking on the router name link in the list. In both cases you will be presented with a dialog that lets you configure the router.

Application publishing and restrictions

Routers can be configured to publish different applications, depending on the intended role of that router and the sensitivity of the published content. An application intended for a specific audience, e.g. intranet users, may be published on a router that is only accessible on the intranet. By limiting where an application is published, the access to that application is restricted.

In this context, access to an application means access to all its services: proxy methods, web services, REST services and web applications. Access to specific components cannot be configured.

SYSTEM is listed as a publishable application in the routers. By not publishing SYSTEM via a given router, the Management UI will not be accessible via that router. SYSTEM is always published by the Administrative Router.

To view the applications published by a router:

Access the Configuration Manager and select Communication -> Routers.
Select the router to view.

The published applications are shown in the Applications area at the bottom of the router view.

To modify the application components published by a router:

Access the Configuration Manager and select Communication -> Routers.
Select the router to configure and click Edit.
In the Applications area, select the Publish checkbox for the applications to publish via that router.
