Enum Class BackboneTopology

java.lang.Object
java.lang.Enum<BackboneTopology>

All Implemented Interfaces:
Serializable, Comparable<BackboneTopology>, Constable
public enum BackboneTopology extends Enum<BackboneTopology>
Defines the inter-metro backbone link topology for connecting Cloud Routers across multiple Equinix metros. Selected via DeploymentWizard.Builder.backboneTopology(BackboneTopology); the wizard turns the chosen topology into concrete PlannedBackboneLinks between the recommended metros, in the order the optimizer ranked them.

  • Enum Constant Details

    • FULL_MESH

      public static final BackboneTopology FULL_MESH
      Every metro connects to every other metro: N*(N-1)/2 links. Maximum path diversity (any single link failure leaves all metros reachable) at the highest link count and cost. The default.

    • HUB_SPOKE

      public static final BackboneTopology HUB_SPOKE
      The hub metro connects to all others: N-1 links. The hub is the highest-ranked recommended metro (the optimizer's first recommendation); spoke-to-spoke traffic transits the hub, which is therefore a single point of failure. Cheapest topology for three or more metros.

    • RING

      public static final BackboneTopology RING
      Each metro connects to the next in rank order, and the last back to the first: N links for three or more metros. Survives any single link failure with one remaining path. With exactly two metros a ring degenerates to the single A–B link (the same one link FULL_MESH would produce) — never a doubly-billed duplicate pair.

  • Method Details

    • values

      public static BackboneTopology[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static BackboneTopology valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
