4 3.Fully Programmable: SDN-Ready, Implementing Rapid Evolution New Services/Functions Hardware-defined: Main functions cannot be expanded. Evolution period: > 24 months The fixed ASIC is used to forward packets. To increase the packet forwarding function, you need to purchase new devices. POF + open APIs Agile Controller Software-defined: hardware performance + software flexibility Functions can be flexibly expanded. Evolution period < 6 months The ENP is used to forward packets. New functions can be implemented through software upgrade or user-defined through POF. Control plane (CPU) Packet forwarding (ASIC) Packet forwarding( ) Control plane (CPU) Traditional switch Agile switch Comparison between traditional switches and Huawei's agile switches How can Information and Communications Technology (ICT) systems between enterprises be more competitive? How can enterprises quickly introduce new services and functions? The answer is a fully programmable architecture, which allows networks to quickly introduce and evolve new functions in a software-defined mode, much faster than traditional hardware-defined networks. The Fully programmable architecture is a unique feature of Huawei s agile network enhanced architecture. The core of this architecture is Ethernet Network Processor (ENP) + Protocol Oblivious Forwarding (POF). This enhanced architecture is the first to implement a rapid expansion of software-defined network functions, leading to more ubiquitous and innovative services. The solution implements a new network function based on both the control and forwarding planes. The SDNenabled open APIs claimed by many device vendors support SDN only on the control plane. Essentially, these APIs cannot implement new functions because packet forwarding is still implemented using nonprogrammable ASCI chips. Huawei is the first in the industry to implement fully programmable control and forwarding planes, allowing new services and functions to be easily defined software-defined in the real sense.

5 4.Quality Awareness: Quick Fault Detection and Excellent Experience ipca (Packet Conservation Algorithm for Internet) Agile Network Automatic Quality Awareness Low user experience can be detected. 0 Wait Accurate fault location Notify the administrator Accurately locate failure points 100% potential risk elimination Quality problems Traditional network > 90% tolerant services Network is unaware of user experience degrading Slow Internet access Slow cloud desktop response Pixelation Low voice quality > 70% faults are difficult to locate Manual fault location: Several hours to several days Repeated fault occurrence Lowered user experience Comparison between traditional networks and Huawei's agile network Neither the traditional network by itself, nor the administrators, can detect network faults before receiving user complaints. Even after receiving complaints, network faults are difficult to detect and thus lay dormant on the network for long periods. According to Huawei's surveys, even though packet loss often occurs on networks where users are present, users are often unaware of the problem. As traditional TCP service traffic can be retransmitted, packet loss slows network access but does not interrupt services. As a result, many users overlook the problem, and, consequentially, it becomes more pronounced when real-time services, such as voice, videos, and desktop clouds, are deployed. Huawei's proprietary ipca technology enables the network to detect service quality and accurately locate faults. If a user's experience is damaged, the network can automatically and accurately detect faults and provide detailed service quality records. By leveraging this technology, administrators can easily detect faults that affect service experience. Huawei Agile Network Solution Brochure / 05

6 5.Agile Campus Network Free Mobility: Ultimate Experience of Mobile Applications Good experience for remote office and mobile office Network resource WAN/Internet User: xx Position: Shenzhen Network resource Beijing Network resource Shenzhen Silicon Valley Service mobility, auto resource allocation, enhanced experience Agile Controller Auto translation Auto deployment 1. Right 2. Priority/Bandwidth 3. Security 4. Storage Free Mobility Users today expect to work in a mobile office style anywhere and anytime. However, the fixed resources of traditional networks are allocated based on physical location, without much focus on user experience. As a result, remote and mobile office experiences are poor, and enterprise intranet access rate is rather low. By introducing the Agile Controller and agile switches, Huawei is the first in the industry to allow network resources to move with users, enhancing user experience and securing network resource utilization. The agile network is the first to make traditional networks user-friendly, while freeing employees from the constraints of the traditional network experience.

7 United Security: Shifting from Single-Point Security Protection to Comprehensive Network Protection Performs Big Data analytics. Agile Controller Dynamically allocates the security resource. Security Resource Center NGFW Third -party security device 1. Collects security events on the entire network Security events include network and security device logs, terminal user behavior logs, and abnormal traffic logs. 2. Performs Big Data analytics The controller analyzes collected mass data and detects potential security risks. Collects security events. Enables security policies. 3. Quickly responds to security events Sends alarms in real time and recommends a response; flexibly delivers security policies and quickly responds to security events. 4. Dynamically allocates security resources Carries out resource pooling of security devices on the entire network and dynamically allocates the security resource according to area, user group, and security event, significantly improving the security protection capabilities of the entire network. United Security over the entire network Confidential information leakage is a serious security concern for mobile office, especially possible leaks through Wi-Fi access points and remote access points over the Internet egress. Traditional firewalls can prevent confidential information leakage at only single points but cannot protect multiple points on the network. To solve the problem of borderless security, Huawei uses a system consisting of An Agile Controller, firewalls, and agile switches to implement comprehensive security protection across the entire network. In this system architecture, security functions are not executed by the egress firewall alone. The Agile Controller collects security events, performs Big Data association analysis, and automatically applies security policies spanning the entire network. Huawei s agile network allows all devices on the network to listen for security events. When suspicious traffic or traffic from an untrusted zone is detected, the Agile Controller dynamically diverts the traffic to a shared security center for in-depth inspection and cleaning. When the traffic is identified to be attack traffic, the Agile Controller instructs network edge nodes to directly isolate the traffic or lower the traffic priority to prevent network threats.

9 6.Agile WAN Agile Controller 400M 30% usage Shanghai 400M, 30% (link usage efficiency) Beijing 1G 1G 1G 900M, 90% (link usage efficiency) Shenzhen Tianjin Nanjing 300M new services cannot be launched. Beijing Shanghai Centralized traffic control Preferential forwarding of high-priority services such as services marked in red Agile Controller Guangzhou Shanghai 400M 400M Shenzhen Hongkong Beijing 300M 1G 1G 300M 1G Shenzhen 900M, 90% (link usage efficiency) Agile WAN WAN leased link bandwidth cost is a key element influencing the experience of most services. According to statistics provided by leading Internet Service Providers (ISPs), data center leased link use efficiency is only about 30%. Improving inter-data center link bandwidth use is critical for reducing link deployment costs and enhancing user experience. Huawei uses the independent path control plane and Agile Controller to calculate the path according to network status to improve bandwidth use efficiency. Huawei provides network status and service priority detection to display service network characteristics, implementing path planning and calculation to increase link use efficiency on the entire network to more than 90%. In addition, high-priority services are scheduled first. Optimized WAN shows WAN links between the data centers in Beijing, Shanghai, and Shenzhen. A new service (requiring 300 Mbit/s bandwidth) must be provided between Beijing and Shenzhen. The bandwidth on this link (shortest link) is insufficient, preventing provision of new services; however, bandwidth use between Beijing and Shanghai, and between Shanghai and Shenzhen, is only 40%. To address this, Huawei introduced Path Computation Element (PCE) technology. Now, the Agile Controller centrally calculates paths, obtains the real-time status of each Network Element (NE), and automatically deploys the new service on the Beijing Shanghai Shenzhen link. The PCE ensures new service provisioning and raises the link bandwidth use to 70% or higher, significantly reducing customer OPEX. Huawei Agile Network Solution Brochure / 09

10 7.Agile Branch Enterprise branch networks currently face challenges brought about by Big Data, cloud computing, diversified IT applications, wireless broadband, and IP-based transformation of industrial terminals. As a result, the number of CT and IT systems keeps increasing, and branch networks become ever more complex. Service deployment, network experience management, and maintenance of a huge number of branches have become major concerns and challenges to branch networks, resulting in high network construction and maintenance costs. Huawei Agile Branch Solution uses a two-layer architecture: Agile Controller + Agile Gateway. Huawei's solution is the first to introduce the Agile Controller into branches, implementing unified deployment and control of branch network resources. The Agile Gateway supports a variety of functions, such as routing, switching, and voice of traditional branch gateways, as well as dynamic uploading of IT applications, implementing CT and IT system convergence and resource sharing.
