Trend & Challenge

Campus Network DevelopmentEnterprise information technologies have gone through three developmental phases: the stand-alone PC era that reduced manual labor, the data era that saw the beginning of information sharing, and the current multimedia- cloud-mobile era that focuses on high-quality service experience.Development of information technologies increases demand for bandwidthEmerging enterprise information technologies push forward the development of campus networks, while the growth of campus networks supports the development of new enterprise information technologies. Rapidly expanding campus networks deploy many bandwidth-consuming new services, such as multimedia and cloud. These new services result in frequent traffic bursts and high traffic volume on enterprise campus networks. Bandwidth demand is enormous and campus networks must be highly reliable.

InformationWeek estimated that in 2011, 65% of enterprises are using or willing to use the Bring Your Own Device (BYOD) work mode. BYOD allows an employee to use any type of terminal anywhere, anytime to access an enterprise network. Wired and wireless sections of a campus network must be seamlessly interconnected so that employees can enjoy the same online experience from any terminal.

Today, enterprise data centers are handling more data than ever, and more services than ever before are migrating to cloud platforms. The east-west traffic model has been replaced by a north-south traffic model on campus networks. The new traffic model requires a small ratio between uplink and downlink bandwidth. As predicted by Gartner (an information technology research and advisory firm), shipments of case-shaped switches with 1000M ports will exceed shipments of those with 100M ports in 2012. A 10GE aggregation network will be a trend of enterprise campus network.Changing campus network traffic model10G Ethernet technology has developed rapidly since the first 10-Gigabit Ethernet standard (IEEE 802.3ae) was introduced in 2002. The 10GBase-T standard was released in 2006, and the 40G/100G Ethernet standard was released in 2010. 10G Ethernet is a mature technology today. The costs of 10GE optical modules and ports are decreasing every year, while the number of 10GE port shipments is increasing rapidly. 10G Ethernet is the technology of choice for high availability networks. Gartner predicts that 10GE port shipments will maintain an annual growth rate of 45.2% during the next five years. A 10GE aggregation network will be essential to the development of services in the future.


Huawei 10GE Campus Network SolutionEnterprise campus networks face several challenges: a shortage of bandwidth resources, reliability problems, and the fact that wired users generally have a better online experience than wireless users. Huawei provides the 10GE campus network solution to help customers cope with these challenges.10GE campus network architecture10GE network, mobility, and the cloud platform are the core of Huawei 10GE campus network architecture:• 10GE network——provides high-speed channels to transmit multimedia, mobile, and a range of other new services. A 10GE network increases bandwidth on a campus network and gives enterprise users fast, flexible access to services.
• Mobility——integrates wired and wireless access, bringing services to users anywhere, anytime.
• Cloud service bearer network——provides reliable and visible cloud services, such as desktop cloud and cloud storage. Cloud services are no longer a mirage but a reality.
