CONTINUED EXAMINATION UNDER 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 6/12/2026 has been entered.
RESPONSE TO ARGUMENTS
Applicant's arguments filed 6/12/2026 have been fully considered but they are not persuasive.
In response to applicant’s arguments with regard to the independent claim 1 rejected under 35 U.S.C. 103(a) that the combination of the references does not teach/suggest the claimed feature “… selecting, using an application executing on a container in a pod on a physical host, a transmission interface associated with the pod over which to transmit a packet based on whether the packet is an internal packet or an external packet … wherein packets are processed either by the host bridge or resources on the DPU …” because the combination of Tang, Sharma and Gadi do not teach the above claimed features; applicant's arguments have fully been considered, but are not found to be persuasive.
The examiner respectfully disagrees, and to further clarify, by combining Sharma’s selecting accordingly (e.g. associated with selecting/using virtual network interface (212)-(213) or virtual function (27A) by pod (202A) for communication in Fig. 3: [0114]; [0122]; [0167]); and wherein packets are processed by either one or another (e.g. associated processing by virtual router or virtual function: Fig. 3; [0014]; [0114]; [0118]-[0122]; [0167]) (Fig. 1; Fig. 3; Fig. 5; [0008]; [0014]; [0072]; [0110]-[0122]; and [0167]) and Gadi’s being processed by the resources on the DPU (e.g. associated with workload being performed using resources of DPU device (109): [0030]) (Fig. 2; [0030]; and [0037]-[0039]) with Tang’s operating with, using an application executing on a container in a pod on a physical host, a transmission interface associated with the pod over which to transmit a packet (e.g. associated with transmission of data between Pods via corresponding interfaces in Fig. 3-4 and Fig. 7-8: [0026]-[0027]; [0059]-[0063]; and [0070]-[0080]) based on whether the packet is an internal packet (e.g. associated with intra-node data transfer: Fig. 3-4; [0059]-[0063]) or an external packet (e.g. associated with communication between nodes executing on different host computers: Fig. 7-8, [0070]-[0080]) (Fig. 3-4; Fig. 6-8; [0003]-[0009]; [0026]-[0030]; [0034]; [0059]-[0063]; and [0069]-[0080]; [0090]), the resulting combination of the references would further teach/suggest the above claimed features.
Furthermore, Tang does teach/suggest the determination of whether data traffic is external traffic or internal traffic prior to transmission as source/transmitter would have determined destination/receiver of the packet prior to transmission when the packet is formed, where the packet is then either communicated via external traffic (e.g. associated with communication between nodes on different host computer) or internal traffic (e.g. associated with communication between nodes on same host computer/intra-node data transferring). Additionally, Sharma does teach/suggest transmitting data traffic via direct interface to virtual function (27A) (i.e. transmission that does not require use of bridge/router: Fig. 3: [0114]; [0122]; [0167]).
As applicant appears to be applying the above arguments for independent claim 1 towards independent claim 20, the examiner will also apply the above response for independent claim 1 towards independent claim 20.

As per claim 19, Tang, Sharma, and Gadi teach/suggest all the claimed features of claim 2 above, where Tang, Sharma, and Gadi further teach/suggest the method comprising wherein the exact match flow entry has a subnet mask of 255.255.255.255 (Tang, Fig. 3-6; Fig. 6-8; [0003]-[0009]; [0026]-[0030]; [0034]; [0050]-[0051]; [0057]-[0063]; [0069]-[0080]; [0090]; Sharma, Fig. 1; Fig. 3; Fig. 5; [0008]; [0014]; [0046]; [0072]; [0078]-[0079]; [0110]-[0122]; [0167]; and Gadi, Fig. 2; [0030]; [0037]-[0039]), wherein it would have been obvious to one of ordinary skilled in the art that the resulting combination of the references further teaches the above claimed features as data is proper communicated for processing.
As per claim 20, claim 20 is rejected in accordance to the same rational and reasoning as the above rejection of claim 1, wherein Tang teach/suggest a method comprising: operating with, using an application executing on a container in a pod on a physical host, a transmission interface associated with the pod over which to transmit a packet based on whether the packet is internal network traffic or external network traffic, wherein each pod on the physical host comprises transmission interface, the transmission interface comprising a virtual Ethernet interface, wherein the virtual Ethernet interface is for internal network traffic and internal network traffic is destined for another pod on the physical host, wherein internet network traffic is transmitted over the virtual Ethernet interface and processed by a host bridge, wherein external network traffic is destined for another pod on a different physical host, wherein external network traffic is transmitted accordingly, being processed by the host bridge, wherein the transmission interface is the virtual Ethernet interface; receiving the packet by the host bridge in the physical host, wherein the packet is destined for a second container on a second pod in executing on the physical host; and transmitting, by the host bridge, the packet to a second virtual Ethernet interface, wherein the second pod is associated with the second virtual Ethernet interface (Fig. 3-4; Fig. 6-8; [0003]-[0009]; [0026]-[0030]; [0034]; [0059]-[0063]; [0069]-[0080]; and [0090]).
Tang does not teach the method comprising:
selecting accordingly,
comprising a set of transmission interfaces, the set of transmission interfaces comprising: a virtual function mapped to a data processing unit (DPU),
executing using a processor on the physical host,
wherein the virtual function is for external network traffic,
being transmitted over the virtual function and is offloaded from the processor on the physical host to the DPU,
wherein network traffic is processed either by one or the DPU.
Sharma teaches/suggests a method comprising: selecting accordingly, comprising a set of transmission interfaces, the set of transmission interfaces comprising: a virtual function operating accordingly, executing using a processor on the physical host, wherein the virtual function is for external network traffic, being transmitted over the virtual function, wherein network traffic is processed either by one or another(Fig. 1; Fig. 3; Fig. 5; [0008]; [0014]; [0072]; [0110]-[0122]; and [0167]).
Gadi teach/suggest a method comprising: being mapped to a data processing unit (DPU), being offloaded from the processor on the physical host to the DPU, being processed by the DPU (Fig. 2; [0030]; and [0037]-[0039]).
It would have been obvious for one of ordinary skill in this art, before the effective filing date of the claimed invention, to include Sharma’s interfacing architecture and Gadi’s DPU into Tang’s method for the benefit of simplifying the configuration and reconfiguration of virtual router (Sharma, [0012]) and offloading workload to the DPU (Gadi, [0030]) to obtain the invention as specified in claim 20.
