1. Network Virtualization

• The virtual distributed switch can ensure the consistency of network configuration when virtual machines migrate between nodes. It provides rich network configuration management functions, dynamic interface binding, and static binding.

• The distributed firewall provides IP access control and virtual machine network QoS to realize unified management of network resources and real-time network monitoring.

• The virtualization router can solve the problem of exit routing after virtualization and provide other functions, including VLAN subinterface, NAT rules, ACL policy, DHCP address pool, DNS proxy, and so on.

2. Virtualization of Network Functions

Network Function Virtualization (NFV) separates network functions from proprietary hardware devices and implements these functions as software to support the infrastructure with complete integration of virtualization components. Sangfor's HCI platform is complete in implementing NFV, including Sangfor network equipment software with leading technology in the security field, including vAF, vAD, vAC, vWOC, vSSLVPN, etc.

3. Distributed Virtual Firewall

A distributed firewall is equivalent to placing a firewall at the exit and entrance of each virtual machine. As long as a policy is configured, it can dynamically adjust in the background no matter how the topology changes, where the virtual machine runs, or change of the IP. Therefore, security protection can be carried out at any time.
