The S9700 series terabit routing switches (S9700 for short) are high-end switches designed for nextgeneration campus networks and data centers to implement service aggregation. Based on Huawei Versatile Routing Platform (VRP), the S9700 provides high L2/L3 switching capabilities and integrates diversified services such as MPLS VPN, hardware IPv6, desktop cloud, video conferencing, and wireless access. In addition, the S9700 also provides a variety of reliability technologies including inservice software upgrade, non-stop forwarding, hardware OAM/BFD, and ring network protection. These technologies improve customers' network operation efficiency, maximize the device running time, and reduce customers' total cost of ownership (TCO). An S9700 can be upgraded to an agile switch when it is equipped with X1E cards, the line cards with Huawei's first Ethernet Network Processor (ENP). Agile switches allow customers to make innovations on their networks.
