ABSTRACT
In cloud computing, resources are allocated on demand and charged by usage. Cloud computing pools computing, network, and storage resources, which results in larger service volumes over higher bandwidth but lower latency. Data Center Networks (DCN) should provide suppression or self-healing capabilities for Layer 2 loops, unknown unicast flooding, policy switching, and redundancy switchover. Applications are migrated dynamically on demand, traffic increases sharply, and DCNs require intelligent O&M. Huawei has launched the cloud DCN solution to address the major challenges faced by DCNs. Huawei has launched the High availability Fabric, Multi Data Center (DC) Fabric, and AI Fabric solutions for enterprise DC, carrier telco cloud, and AI distributed computing or storage, addressing the demands for quick cloudification. As services are deployed across DCs, service access relationships and policy management between DCs become more complex. Application policies and mutual access within DCs become increasingly complex.
