Link Representation¶
Extends Network Resource schema.
A Link object describes that there is a unidirectional/bidirectional connection between two Ports.
A Link SHOULD have and attribute endpoints which is a list of two hyperlinks to Ports if the Link is bidirectional or an object with two attributes source and sink if the Link is unidirectional.
JSON Schema¶
See http://unis.crest.iu.edu/schema/20120709/link.
Attributes¶
The following table contains only the Link specific attributes, for the attributes extended from network resource see Network Resource schema.
| Name | Value | Description |
|---|---|---|
| directed | boolean | true Link is unidirectional. false Link is bidirectional. |
| capacity | number | Link’s capacity in bytes per second. |
| endpoints | list/object | List of two hyperlinks to Ports if bidirectional. Object of source and sink if unidirectional. |
Example¶
The following is an unidirectional Link representation example:
{
"$schema": "http://unis.crest.iu.edu/schema/20120709/link#",
"id": "link1",
"selfRef": "https://example.com/links/link1"
"ts": 1337711394175048,
"directed": true,
"capacity": 10000000000,
"endpoints": {
"source": {
"href": "https://example.com/ports/1",
"ref": "full"
},
"sink": {
"href": "https://example.com/ports/2",
"ref": "full"
}
}
}
The following is an bidirectional Link representation example:
{
"$schema": "http://unis.crest.iu.edu/schema/20120709/link#",
"id": "link2",
"selfRef": "https://example.com/links/link2",
"ts": 1337711394175048,
"directed": false,
"capacity": 10000000000,
"endpoints": [
{
"href": "https://example.com/ports/3",
"ref": "full"
},
{
"href": "https://example.com/ports/4",
"ref": "full"
}
]
}
