Latest Patents

Andrew's latest patents include innovative methods for Internet protocol security and security parameter index summarization and data routing. One of his patents describes techniques for routing Internet Protocol security (IPsec) data packets. An index is assigned to a Security Parameter Index (SPI) header of the IPsec data packet. This index includes information for routing the data packet to a specific Encapsulating Security Payload (ESP) processor. The data packet can be routed using techniques analogous to conventional routing protocols, such as the IPv4 routing protocol. This approach allows for the use of less expensive routing protocols rather than relying solely on costly load balancing techniques. Additionally, it enables the routing of data packets using established routing techniques developed over decades.

Another patent focuses on network path proof of transit using in-band metadata. This system provides methods for verifying the proof of transit of network traffic through multiple network nodes. Information is obtained about a packet at a network node, which may include in-band metadata. Verification information is read from this metadata, and updated verification information is generated based on the configuration of the network node. This updated information is then written back to the in-band metadata in the packet before it is forwarded through the network.
