Huawei Agile WAN Solution

WAN Development and Challenge As more Enterprise services are deployed on IT systems and transmitted over IP networks, Enterprise networks are expanding to support more service types. Enterprise service informatization Comprehensive service Data processing Computer interconnection & file sharing Information sharing Office system Video conferencing Wireless access Voice call Desktop Telepresence Multimedia Cloud Mobile Cloud storage BYOD Spontaneous Telepresence Desktop cloud Enterprise application store Mobile video Cloud computing Internet of Things Service network Development of enterprise IT applications Enterprise informatization Enterprise networks are vital for ensuring service availability; therefore, network reliability, security, and maintainability must be guaranteed to ensure uninterrupted services. The bandwidth demands of Enterprise services on network resources is increasing, especially on Wide Area Network (WAN) bandwidth; however, WAN bandwidth is limited and network resources must be allocated logically to ensure optimal user experience of key applications and to minimize investment costs. Enterprise WANs must be expanded and upgraded to support developing services. WANs must be scalable, able to evolve to ensure service continuity, and maximize Return on Investment (ROI). 2

Stable network architecture 4

Agile Service Provisioning Huawei s Agile WAN Solution features the following advantages for agile service provisioning: SDN-based traffic scheduling improves WAN link efficiency by three times. Huawei s Agile WAN Solution introduces its Agile Controller to automatically compute service paths and optimize bandwidth efficiency based on network states and service requests. In addition, this solution fully displays service network characteristics through network state and service priority awareness; it implements path planning and computing over the entire network, which improves link efficiency to over 90 percent. Beijing Tianjin Nanjing Shenzhen Hongkong WAN SDN traffic scheduling Shanghai Guangzhou Provides various types of QoS to guarantee support for multi-service transmission. Hierarchical Quality of Service (HQoS) schedules queues at the physical, logical, and application/service level using different traffic policies. This implements hierarchical traffic management as well as management of different users and services. Huawei supports 5-level HQoS scheduling, and each DS-TE supports eight CTs, providing a refined E2E QoS solution. Unequal-Cost Multi-Path Routing (UCMP) and load balancing allocate traffic to backup links based on their bandwidth capacities. This permits more logical use of backup links, eliminates an idle high-bandwidth link and packet loss on the low bandwidth link. WAN acceleration products compress traffic based on application characteristics to increase network bandwidth utilization. The WAN acceleration module significantly increases transmission speed and reduces bandwidth requirements by 60 to 70 percent, saving up to 38 percent on costs. 5
