LinkLayerizer

LinkLayerizer integrates networks of different layers, to create a multi-layer network.

Lower network : Topology of the lower layer in a multi-layer.(e.g. optical transport network)
Upper network : Topology of the upper layer in a multi-layer.(e.g. Packet Transport network)
Layerized network :Network topology that are available in the upper layer.

Operating specifications of the LinkLayerizer.

  • Topology
    layerized network and the upper network, the same topology.

  • Flows
    Flow will be reflected in the upper network when it is set at layerized network.
    flow of lower network that satisfies the condition(*) is converted to link of layerized network.

(*)Flow connecting the boundary port each other in the underlying network has been set.

  • Packets
    LinkLayerizer will drop it.

  • boundary
    Lower network and upper network, are connected through the boundary information.
    The boundary information is need on "network" and "node" and "port".

  • Create Instance of LinkLayerizer.

    Generate an instance of LinkLayerizer by performing a PUT(or POST) to the System Manager.

    PUT <base_uri>/components/<comp_id>

key value description
id <String> Unique Identifier in ODENOS.
type "LinkLayerizer" ObjectType
cm_id <String> Specify the componentManager.Property.id to generate an instance. (Optional)

  • Component Connections

    Connection of LinkLayerizer and Network by performing a PUT( or POST) to the System Manager.

    network | Connection possible number | connection_type ------------------|----------------------------|---------------------------------- lower network | Only one | "lower" upper network | Only one | "upper" layerized network | Only one | "layerized"

    PUT <base_uri>/connections/<conn_id>

key value description
id <String> Unique Identifier in ODENOS.
type 　　 　 "LogicAndNetwork"
connection_type "lower" or "upper" or "layerized"
state none default "initializing"
logic_id <String> LinkLayerizer ID
network_id <String> Network ID
