Patent number: 11916879Abstract: Some embodiments of the invention provide a novel method for performing firewall operations on a computer. The method of some embodiments instantiates first and second firewall processes on the computer. These two processes are two separate processes, which in some embodiments have separate memory allocations in the memory system of the computer. The method uses the first firewall process to examine a data message to determine whether an encryption based firewall policy (e.g., a TLS-based firewall policy) has to be enforced on the data message. Based on a determination that the encryption-based firewall policy has to be enforced on the data message, the method provides metadata, which is produced by the first firewall process in its examination of the data message, to the second firewall process. The second firewall process then uses the provided metadata to perform an encryption-based firewall operation based on the encryption-based firewall policy.Type: GrantFiled: January 3, 2022Date of Patent: February 27, 2024Assignee: VMware LLCInventors: Manish Jain, Mani Kancherla

Patent number: 11899654Abstract: An optimistic byzantine agreement protocol (the protocol) first tries to reach agreement via an efficient deterministic algorithm (synchronous protocol) that relies on synchrony for termination. If an agreement is not reached (e.g., due to asynchrony), the protocol uses a randomized asynchronous algorithm (asynchronous protocol) for fallback. Although randomized asynchronous algorithms are considered to be costly, the rationale here is to bound communication in non-synchronous runs after an equivalent cost has already paid.Type: GrantFiled: September 22, 2020Date of Patent: February 13, 2024Assignee: VMware LLCInventor: Alexander Spiegelman
