Allowable Subject Matter
Claims 5 and 16 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant's arguments filed 10/3/2025 have been fully considered but they are not persuasive. Applicant amends the limitations in the claim and argues the references do not disclose the amended limitations. Applicant argues Zhang disclose TE1 receives a data packet from TE2 but does not receive a request to transmit data from a host system via a device interface. Applicant also argues Zhang does not disclose receiving request on a first reliable transport protocol nor transmitting packet based on second reliable transport protocol. In response, a host system is any device that can communicate and provide resources or services with other devices on a network. The network device in Zhang can be a server, Para [0027] and a server can be a host. Therefore, Zhang does disclose receiving a packet (or request) from a host. Applicant’s other argument that Zhang does not disclose first and second reliable protocols is moot as, Zhang was not used to disclose that. Dawes is used to disclose that limitation. Applicant states Marolia teaches use of RDMA verbs and uses InfiniB and verbs application program interface (API) to enable RDMA writes directly to destination memory but does not teach a call to RDMA API using first reliable transport protocol but then transmits the data using second reliable transport protocol. In response, Applicant argues Marolia doesn’t disclose switching the reliable transport protocol but that feature is disclosed by Zhang. Further argument is moot in view of new reference being used in the current office action.
