HCN_NETWORK

Ein HCN-Netzwerk ist eine Entität, über die ein Hostcomputenetzwerk mit den zugehörigen Systemressourcen und Richtlinien dargestellt wird. Ein HCN-Netzwerk kann in der Regel Folgendes umfassen:

  • Metadaten (ID, Name, Typ)
  • Einen virtuellen Switch
  • Einen virtuellen Netzwerkadapter als Host (fungiert als Standardgateway für das Netzwerk)
  • Eine NAT-Instanz (falls für den Netzwerktyp erforderlich)
  • Eine Gruppe von Subnetz- und MAC-Pools
  • Netzwerkweite Richtlinien, die angewandt werden sollen (z. B. ACLs)

HCN-Netzwerkentitäten werden durch RPC-Kontexthandles des Typs HCN_NETWORK dargestellt.

HCN_ENDPOINT

Ein HCN-Endpunkt ist eine Entität, über die ein IP-Endpunkt in einem HCN-Netzwerk mit den zugehörigen Systemressourcen und Richtlinien dargestellt wird. Ein HCN-Endpunkt besteht in der Regel aus:

  • Metadaten (ID, Name, ID des übergeordneten Netzwerks)
  • Der zugehörigen Netzwerkidentität (IP-Adresse, MAC-Adresse)
  • Endpunktspezifischen Richtlinien, die angewandt werden sollen (ACLs, Routen)

HCN_NAMESPACE

Ein HCN-Namespace ist eine Entität, über die ein Hostcompute-Netzwerknamespace dargestellt wird. Über Namespaces können Sie isolierte Netzwerkumgebungen auf einem einzelnen Host verwenden, wobei jeder Namespace über eigene, von anderen Namespaces getrennte Netzwerkschnittstellen und Routingtabellen verfügt.
