Huawei Confidential 5 • During telephone communication, audio signals are sent and received. • Audio signals are continuously sent and received. After a call is connected, the communication link is exclusively occupied as long as the communication is on. • The telephone communication is single-task, meaning that a single user can make only one call at a time. • During data communication, data blocks (packets) are sent and received. • Data blocks are discontinuous, and no communication resource is occupied if no packet is sent and received. • Typically, a computer has multiple tasks, and the tasks use communication resources at the same time to improve utilization. Moreover, one single computer can participate in multiple data communication tasks at the same time. Email, online shopping, download... ⚫ Telephone communication: It refers to the long-distance communication between people via sending and receiving continuous audio signals between telephones. ⚫ Data communication: It refers to the communication between computers via sending and receiving data blocks between computers. The data block is also called a packet. During a call, the communication usually involves one-way and intermittent. As such, the actual bandwidth usage is lower than 5%. Email, online shopping, download... During data communication, packets are grouped to implement efficient multiplexing of terminals and links, greatly improving the usage efficiency of communication networks. Data Communication: Computer Communication, Which Uses Packets to Implement Efficient Multiplexing Telephone communication: audio signal, continuous communication, and single-task Data communication: data block, discontinuous, and multi-task.

It is generally built by enterprises themselves, that is, routing their own optical fibers and network cables for easy deployment, easy expansion, and abundant resources. ⚫ At Huawei, each research center or rep office has a campus network, and the headquarters in Bantian, Shenzhen, China has a super-large campus network. The campus network is connected to the WAN through routers and firewalls. ⚫ Huawei's IT network has 80,000 APs, 80,000 campus switches, 20,000 DCN switches, 3400 routers, and 2600 firewalls, connecting 400,000 terminals. Data Communication Network Around Us: Campus Network The campus network connects people and things on a campus. It underpins diversified services like automatic clock-in/out, smart access control, Projector, and video conference. Wireless: Wi-Fi APs connect various wireless terminals, including laptops and mobile phones. | Wired: Switches connect wired terminals and Wi-Fi APs.

Huawei Confidential 8 The data center network (DCN) interconnects computing servers and storage servers in the DC. Take Huawei Dongguan enterprise data center (EDC) as an example: About 45,000 computing servers and storage servers on 3000 racks are interconnected. Similar to a campus network, a DCN is also a type of LAN, providing a coverage range of less than 1 km. Enterprises themselves can route optical fibers to enjoy abundant resources.
