Problems solved by technology

However, partitioning a network from one region into multiple regions, or from multiple existing regions into more regions, is a very challenging and time-consuming task as it involves major network architecture changes
Additionally, when a network is split from one region into multiple regions, or from several existing regions into more regions, services hosted by the network may be disrupted

Embodiment Construction

[0049] It should be understood at the outset that, although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but rather be within the scope of the appended claims and their equivalents Modified within the full range of .

[0050] The disclosed embodiments seek to reduce service disruption when a network is reorganized from one area to multiple areas or from multiple existing areas to more areas. In one embodiment, partitions are abstracted as a single pseudonode. Abstraction means that partitions are transformed or turned into individual pseudonodes. When migrating a partition to a single pseudonode, there is little...

Abstract

Various systems and methods for migrating a zone to a pseudo node are described herein including a method performed by a zone edge node. In an embodiment, the method includes receiving, by the zone edge node, an execution request to initiate migration from the zone to the pseudo node. The method also includes sending, by the zone edge node, at least one Hello packet to a zone external node adjacent to the zone edge node for requesting the zone external node to create an adjacency between the pseudo node and the zone external node on the zone external node. The method further includes creating, by the zone edge node, the adjacency between the pseudo node and the zone external node on the zone edge node.

Description

[0001] Related Application Cross Reference [0002] This application requires the application number 62 / 868,684 submitted by Huaimo Chen et al. on June 28, 2019, and the title of the invention is "System and Method for Smoothly Abstracting IGP Zone (System and Method for Smoothly Abstracting IGP Zone) ", the entire contents of which are incorporated by reference in this application. technical field [0003] The present application relates to network communications, and more particularly, to a system and method for abstracting interior gateway protocol (IGP) partitions in an area into a single node. Background technique [0004] The International Organization for Standardization: 10589 (ISO10589) and Request for Comments: 2328 (RFC2328) describe two levels of areas, the Level 1 area in Intermediate System-to-Intermediate System (IS-IS) and the Level 2 areas, and backbone areas and non-backbone areas in the Open Shortest Path First (Open Shortest Path First, OSPF) protocol. ...
