9 results about "Virtual firewall" patented technology

A virtual firewall (VF) is a network firewall service or appliance running entirely within a virtualized environment and which provides the usual packet filtering and monitoring provided via a physical network firewall. The VF can be realized as a traditional software firewall on a guest virtual machine already running, a purpose-built virtual security appliance designed with virtual network security in mind, a virtual switch with additional security capabilities, or a managed kernel process running within the host hypervisor.

Method and apparatus for implementing service chain pseudo-proxy

ActiveCN120263464BIntelligent NetworkVirtual firewall
The application provides a method and device for implementing a service chain pseudo-proxy. The method comprises providing a corresponding relationship between a pseudo-proxy segment identifier (SID) and a virtual firewall IP address on an intelligent network card, the intelligent network card being located on a server carrying a virtual firewall; receiving an SRv6 packet from a service chain interface; identifying that the SID list of the received SRv6 packet contains a pseudo-proxy SID to generate a flow table item; wherein the matching item is the packet characteristic information of the outer MAC header of the SRv6 packet; the action item is the SRH header of the cached SRv6 packet; based on the SID list of the SRv6 packet containing the pseudo-proxy SID, the IP address of the virtual firewall is found; the SRH header of the SRv6 packet is stripped and cached, and the SRv6 packet is sent to the virtual firewall.
