Explanations of Words and Concepts

Word/concept	Definition
Relay Parent	The relay parent is the grid which receives the relay connection from the relay child. A relay parent may have many relay children, and it may itself be the relay child of another grid.
Relay Child	The relay child is the grid from which the relay connection is initiated. A relay child may only have one relay parent. A relay child grid may itself be the relay parent of another grid.
Answering Grid	The answering grid has the server component of the proxy called through relay. This is the recipient of a relay call, and may be either a parent or a child grid.
Calling Grid	The calling grid has the client component of the proxy called through relay. The caller may be either a parent or a child grid.
Relay Channel	The connection between a calling grid and an answering grid.
Proxy Method	The grid supports proxy methods, which offer the possibillity to call methods in other grid applications, possibly in other grids.
Proxy ID	A grid application that offers a proxy method to be called over a relay channel must register a proxy ID for that method so that a client application can map users to the correct answering grid.
Relay User	The relay user is a concept to enable session transfer from one grid to another. The session is transferred from the calling grid to the answering grid. The relay user is defined in the External Systems Management UI of the answering grid.
Relay User ID	The relay user ID is the name a user gets in the session obtained through a relay channel.
Local User ID	The local user ID is name a user gets in a grid when logged on using the normal session provider. This is also known as the grid principal name.
Relay Connection Type	Each grid participating in a relay connection has control over what access the other grid – and its other relay connections, if any – should have. The possible values are peer only, peer chain, full access and no access.

Relay Parent

The relay parent is the grid which receives the relay connection from the relay child. A relay parent may have many relay children, and it may itself be the relay child of another grid.

Relay Child

The relay child is the grid from which the relay connection is initiated. A relay child may only have one relay parent. A relay child grid may itself be the relay parent of another grid.

Answering Grid

The answering grid has the server component of the proxy called through relay. This is the recipient of a relay call, and may be either a parent or a child grid.

Calling Grid

The calling grid has the client component of the proxy called through relay. The caller may be either a parent or a child grid.

Relay Channel

The connection between a calling grid and an answering grid.

Proxy Method

The grid supports proxy methods, which offer the possibillity to call methods in other grid applications, possibly in other grids.

Proxy ID

A grid application that offers a proxy method to be called over a relay channel must register a proxy ID for that method so that a client application can map users to the correct answering grid.

Relay User

The relay user is a concept to enable session transfer from one grid to another. The session is transferred from the calling grid to the answering grid. The relay user is defined in the External Systems Management UI of the answering grid.

Relay User ID

The relay user ID is the name a user gets in the session obtained through a relay channel.

Local User ID

The local user ID is name a user gets in a grid when logged on using the normal session provider. This is also known as the grid principal name.

Relay Connection Type

Each grid participating in a relay connection has control over what access the other grid – and its other relay connections, if any – should have. The possible values are peer only, peer chain, full access and no access.
