Development of enterprise IT applications
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.
Solution Overview
Huawei Agile WAN Solution architecture
Huawei has launched its Agile WAN Solution to solve the challenges of insufficient bandwidth,
poor reliability, lack of security, and maintainability.
Stable network architecture, agile service provisioning, comprehensive network security, and unified
network management are the core characteristics of Huawei’s Agile WAN Solution.
■ Stable network architecture – Huawei’s Agile WAN Solution provides device-level and protocol-level reliability. Huawei-developed core chips enable easy upgrades. IPv6 technologies or a transition solution from IPv4 enable network architecture evolution.
■ Agile service provisioning– Huawei’s Agile WAN Solution implements unified traffic scheduling based on Software-Defined Networking (SDN) to links that transmit multimedia and cloud services. A variety of load-balancing technologies and WAN-acceleration products are used to maximize link efficiency and ROI. Additionally, Huawei’s solution provides differentiated service experience for users through refined bandwidth management based on Quality of Service (QoS) policies..
■ Comprehensive network security – Huawei’s Agile WAN Solution provides refined service identification and multi-dimensional policies to provide border security and defend against malicious attacks and unauthorized access.
■ Unified network management – Huawei’s Agile WAN Solution supports unified management of IP and optical networks, implements visualized monitoring and Operations and Maintenance (O&M) of network traffic, which provides high quality through a simplified, unified Network Management System (NMS).

Stable Network Architecture
Huawei’s Agile WAN Solution provides a comprehensive collection of Enterprise networking
products, including optical transmission/Ethernet/WLAN/WAN access routers, aggregation/core
routers, network security products, and NMS for a complete End-to-End (E2E) fundamental
network solution. Huawei’s Agile WAN Solution provides device-level, network-level, and
topology-level network reliability.
■ Device-level reliability:
• Hardware redundancy design: Dual power supplies, dual Main Processing Units (MPUs), and hot-swappable cards.
• In-Service Software Upgrade (ISSU): Hot patches.
• Single-point failure recovery: Non-Stop Forwarding (NSF) and non-stop routing (NSR).
■ Protocol-level reliability:
• Network link and node fault detection technologies: Static/dynamic Bidirectional Forwarding Detection (BFD), single hop/multi-hop BFD, and IPv6 BFD.
• Industry-leading quick switchover technologies: IP Fast Reroute (FRR), Label Distribution Protocol (LDP) FRR, and VPN FRR.
■ Topology-level reliability:
• Dual-plane network
• Double node dual link
• Networks of two carriers
Device-level reliability: Dual MPUs for routers, NSF, and NSR
Protocol-level reliability: FRR and BFD
Topology-level reliability: Dual systems, dual planes, dual uplinks, and UCMP.
WAN SDN traffic scheduling
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.
■ 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.
