ZXR10 V6000 vBRAS Virtual Broadband Multi-Service Gateway

  • The ZXR10 V6000 vBRAS carrier-class virtual broadband multi-service gateway achieves control/forwarding separation and software /hardware decoupling with SDN & NFV technology, so as to implement control plane cloudification, fast and flexible service deployment, and centralized control of configuration and OAM. It overcomes the following shortages of traditional BRAS: uneven resource utilization rates at the service control layer, long service deployment period and high OAM workload caused by distributed configuration, and reduces operators’ OPEX and CAPEX. Building a stable and reliable metro edge with elastic resources and rich services is an inevitable development trend of future carrier networks. The ZXR10 V6000 vBRAS can facilitate the intelligentization and virtualization transformation of metro edge networks. 

    Advanced architecture meets carrier-class network operation requirements

    ZTE vBRAS employs separated control plane/forwarding plane architecture. The control plane performs service control by software virtualization, overcoming the problem of insufficient resource on the control plane of the existing BRAS devices. The forwarding plane uses the NP-based high-performance forwarding pool.

    l  One single control plane can provide the access capability for millions of users, and it supports dynamic elastic scaling according to network scale.

    l  The high-performance forwarding pool provides single-slot 400G forwarding capability and supports evolution to 1T. It carries high-bandwidth and high-QoS services to cope with the increasing bandwidth challenges of carrier-class networks.

    l  The universal X86-based virtual forwarding pool supports elastic capacity expansion. It can be used to carry high-concurrency, low-bandwidth and low-QoS services to share sessions and reduce the flow table overhead of the high-performance forwarding pool. 

    Smooth evolution protects customer investment

    l  The control plane is completely decoupled from the forwarding plane and can be deployed flexibly. It can be deployed directly on the existing metro backbone network without changing the existing network architecture. It also supports seamless evolution towards future DC-centric networks.

    l  The high-performance forwarding devices can be provided by upgrading BRAS/MSE/BNG devices on the existing network to reuse the existing NE resources and fully protect customer investment.

    Full service transport covers all service types in MAN

    l  Completely virtualized BRAS services: supports IPoEv4/v6, PPPoEv4/v6, IPTV multicast, L2TP and IP Host services; covers home triple-play, personal WiFi and enterprise and Internet private line services.

    l  Hybrid SR services: supports MPLS L3/L2 VPN, IPSec VPN and GRE services; covers enterprise VPN services.

    l  The powerful CGN function and complete CGN protection solution guarantee private network IPv4 service provisioning and reliability.

    l  High-performance QoS capability boosts precision operation and traffic operation of fixed network broadband services.

    Redundant backup highly improves service reliability

    l  Redundant backup is configured for all components on the control plane to perform seamless switchover when one component fails. Control planes of vBRAS can be deployed cross-DC backup, which enables seamless switchover to the standby control plane when the active control plane fails, fully guaranteeing reliability of the control plane.

    l  The forwarding plane has natural redundancy and achieves service load balancing. It also supports multi-service hot standby. The service is automatically switched to the standby device when the active forwarding device fails, without the need for redialing. It is more flexible and efficient compared with hot standby deployment of traditional BRAS.

    Extremely simplified OAM shortens new service provisioning period

    l  The vBRAS implements centralized management and control of the control plane. Broadband services only need to be configured on the control plane before they are automatically distributed to the forwarding plane, which substantially simplifies the configuration workload.

    l  In the whole system, only the control plane needs to interconnect with all service platforms and they appear as a logical structure to the outside. Expansion of the forwarding plane does not increase any workload of interconnection with the service system.

    l  When the deployment of a new service involves software upgrade, only the control plane needs to be upgraded, substantially shortening new service deployment period.
