Financial Agile Network Solution

The data volume and switching requirements of banks are increasing. However, traditional network architectures, with their primitive fault location measures and unreliable DR mechanisms, are slowing down the development of banking services.

Huawei’s Financial Agile Network Solution is an intelligent solution based on a Software-Defined Networking (SDN) framework. This solution has two architectural innovations: quality awareness and smooth evolution. It allows networks to provide financial services quickly and flexibly. This agile network solution adapts a flattened network architecture that integrates production and office networks to efficiently transmit large amounts of data. It helps customers construct smart financial networks that are physically converged but logically isolated.

Traditional network architectures face challenges such as “tree-structured” networks suffering from low data transmission efficiency and new services introducing more access terminals to financial networks. Other challenges are Big Data applications requiring larger network bandwidths and more efficient data transmission between production and office networks, and the application of cloud computing technologies requiring ICT infrastructure sharing and cross-data center VM migration.

  • WAN (Multi-Center Core Carrier Network)

    The solution replaces traditional tree-structured networks with a core carrier network in a ring topology. Branches and service centers connect to the banking system through the nearest nodes, improving the efficiency of the backbone network with:

    • An outloop carrier network with a 3-layer architecture of core, aggregation, and access

    • A carrier network with three or four core nodes and multiple aggregation nodes, suitable for application in multi-service center layouts

    • A dual-plane core that enhances network stability and lowers the network’s average latency

  • Data Center Network

    To meet cloud-based service requirements, the large Layer-2 network supports VM migration between data centers, rapid deployment of new services, and flexible, dynamic adjustment of infrastructure resources using:

    • A large Layer-2 network in the same city, allowing flexible service deployment and supporting active-active architectures

    • An internal ring structure, with a two-site, three-center disaster recovery network

  • Agile Campus and Branch

    The solution uses E2E security protection measures, including terminal access control and rights management, to meet the requirements of campus production, office service integration, and mobile office with:

    • Large-scale coverage, that includes traditional campus networks, branches, and service centers

    • A centralized service processing center
