Title
(EN) LOGICAL ROUTER COMPRISING DISAGGREGATED NETWORK ELEMENTS
(FR) ROUTEUR LOGIQUE COMPRENANT DES ÉLÉMENTS DE RÉSEAU DÉSAGRÉGÉS
Abstract
(EN)
A logical router includes disaggregated network elements that function as a single router and that are not coupled to a common backplane. The logical router includes spine elements and leaf elements implementing a network fabric with front panel ports being defined by leaf elements. Control plane elements program the spine units and leaf to function a logical router. The control plane may define operating system interfaces mapped to front panel ports of the leaf elements and referenced by tags associated with packets traversing the logical router. Redundancy and checkpoints may be implemented for a route database implemented by the control plane elements. The logical router may include a standalone fabric and may implement label tables that are used to label packets according to egress port and path through the fabric.
(FR)
Un routeur logique comprend des éléments de réseau désagrégés qui fonctionnent comme un seul routeur et qui ne sont pas couplés à un fond de panier commun. Le routeur logique comprend des éléments troncs de type spine et des éléments feuilles de type leaf implémentant un tissu de réseau avec des ports de panneau frontal définis par des éléments feuilles. Des éléments de plan de contrôle programment les unités troncs et la feuille pour faire fonctionner un routeur logique. Le plan de contrôle peut définir des interfaces de système d'exploitation mappées sur des ports de panneau frontal des éléments feuilles et référencées par des étiquettes associées à des paquets traversant le routeur logique. La redondance et les points de contrôle peuvent être implémentés pour une base de données de routage implémentée par les éléments de plan de contrôle. Le routeur logique peut comprendre un tissu autonome et peut implémenter des tables d'étiquettes qui sont utilisées pour étiqueter les paquets selon un port de sortie et un trajet à travers le tissu.
