[0015] One or more embodiments of the present invention provide dynamic balancing of inbound traffic in a processing system with multiple network interfaces enabled. In some environments, the processing system is configured with multiple network interface cards (NICs) on a virtual local area network (VLAN) for redundancy; NICs are also referred to as network adapters. Network adapters such as those described herein can utilize Address Resolution Protocol (ARP) offloading support. As an example, IBM's z / OS network environment utilizes Open Systems Adapters (OSAs) as network adapters. In some environments, multiple Virtual Internet Protocol Addresses (VIPAs) represent multiple applications and prevent connection loss in the event of network adapter (i.e., network adapter) failure.

[0016] Figure 1 A block diagram of a processing system 102 according to aspects of this disclosure is depicted. This example processing system 102 includes a processing device 104 and a memory 106. According to aspects of this disclosure, the techniques described herein can be implemented using a combination of hardware and programming. The program can be processor-executable instructions stored in tangible memory, and the hardware can include the processing device 104 for executing those instructions. Therefore, the system memory (e.g., memory 106) can store program instructions that, when executed by the processing device 104, implement the techniques described herein.

[0017] Processing system 102 may also include one or more network adapters (e.g., Figure 6 Network adapter 616). In Figure 1 In this example, processing system 102 includes two network adapters, referred to as Open Systems Adapters (OSA), as follows: network adapter 108 and network adapter 110. Each of network adapters 108 and 110 is communicatively connected to network device 116 via network 112, such as... Figure 1 The arrows indicate wired and / or wireless links. It should be understood that this technology can be used with other numbers and / or types of network adapters; for example, additional OSAs can be used, including three, four, five, six, etc. For instance, utilizing more than one network adapter for redundancy can be useful, providing load balancing, resilience, etc. In a load-balancing scenario, network traffic can be distributed across multiple interfaces, and in a resilient scenario, a network adapter failure will not cut off network access to the processing system because another network adapter can support network communication.

[0018] Network 112 represents any one or a combination of different types of suitable communication networks, such as cable networks, public networks (e.g., the Internet), private networks, wireless networks, cellular networks, or any other suitable private and / or public networks. Furthermore, network 112 may have any suitable communication range associated with it and may include, for example, global networks (e.g., the Internet), metropolitan area networks (MANs), wide area networks (WANs), local area networks (LANs), or personal area networks (PANs). Additionally, network 112 may include any type of medium capable of carrying network traffic, including but not limited to coaxial cable, twisted pair, optical fiber, hybrid fiber-coaxial (HFC) media, microwave terrestrial transceivers, radio frequency communication media, satellite communication media, or any combination thereof. In some examples, network 112 includes a switching structure 114 that exchanges network services / data between devices, such as between processing system 102 and network device 116.

[0019] exist Figure 1In the example shown, the processing system 102, configured and arranged as illustrated, utilizes network adapters 108 and 110 on the same subnet. This configuration is useful for static routing (i.e., when dynamic routing is not used). This enables the use of a flat Layer 2 network. The processing system 102 can utilize a multihomed approach, where each interface (i.e., network adapters 108 and 110) is provided as a separate Internet Protocol (IP) interface to the stack and network 112 executing on the processing system 102. In such an example, the network layer of each stack sees multiple IP interfaces, which can be accessed and controlled individually. Network 112 also sees multiple IP interfaces, which can be routed to individually. Each IP interface uses its own IP address. In other examples, the processing system 102 can utilize network adapters 108 and 110 on different subnets. This approach is useful when dynamic routing is used.

[0020] In an IBM z / OS network environment, it might be desirable to configure multiple network adapters (e.g., network adapter 108, network adapter 110) on a single Virtual Local Area Network (VLAN) for redundancy. It would also be desirable to use multiple Virtual IP Addresses (VIPAs) to represent multiple applications and prevent connection loss in the event of a network adapter failure. This is efficient because each VIPA on the stack can be reached from any network adapter (e.g., any one of network adapters 108, 110). When a VIPA is defined in the same subnet as one of network adapters 108, 110, or 110, network adapter 110 is responsible for responding to Address Resolution Protocol (ARP) requests and sending gratuitous ARPs for the VIPA. This network adapter (e.g., one of network adapters 108, 110) is referred to as the "VIPA owner," and because it is the VIPA owner, its MAC address (virtual or real) is perceived by the rest of network 112 as the MAC address of each VIPA registered to it.

[0021] Because a single network adapter acts as the owner of a VIPA, all inbound packets destined for any VIPA will pass through that network adapter, excluding any other OSAs that would otherwise be available for inbound traffic on the same subnet. This can overload the single network adapter, leading to potential packet loss, performance issues, and unbalanced use of the network adapter.

[0022] Some traditional methods utilize link aggregation. However, link aggregation is not a feature supported by IBM on z / OS. Other traditional methods use Layer 3 dynamic routing protocols such as Open Shortest Path First (OSPF) to advertise VIPA addresses through each OSA. However, this solution is undesirable in smaller, less complex networks due to the processing and management burden imposed on z / OS by implementing dynamic routing.

[0023] Therefore, this technology addresses these and other drawbacks of conventional methods by providing a technique for balancing inbound traffic across OSA in a z / environment. More specifically, the VIPA owner function is implemented by registering each VIPA (using Transmission Control Protocol / Internet Protocol (TCP / IP)) to a single qualified network adapter that exists in the same subnet as the VIPA. According to one or more embodiments described herein, inbound traffic is distributed across available network adapters by registering applicable VIPAs on qualified network adapters. For example, applicable VIPAs can be registered evenly on qualified network adapters (e.g., for 100 VIPAs and 4 OSA adapters in the same subnet, 25 VIPAs are registered / assigned to each network adapter). In some examples, the inbound packet count or data count for each VIPA is monitored, for example, at set time intervals, and individual VIPAs can be re-registered to different OSA to better balance the packet / data counts on the network adapters.

[0024] Figure 2 A method 200 for performing inbound load balancing according to one embodiment is shown. Method 200 can be performed by any suitable processing system (e.g., processing system 102, processing system 600, etc.), any suitable processing device (e.g., processing device 104, processing device 602, etc.), and / or combinations thereof. Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 Method 200 is described, but not limited to it. In particular, Figure 3 , Figure 4 and Figure 5 Various embodiments of four network adapters having seven VIPAs registered therein are described. Referring to these three figures, the first digit of the component numbers differs from the figure numbers, but these three figures otherwise depict and refer to the same network adapter / VIPA. For example, in different embodiments, VIPA 310, VIPA 410, and VIPA 510 are the same VIPA. Similarly, in different embodiments, network adapter 302, network adapter 402, and network adapter 502 are the same OSA.

[0025] In box 202, method 200 includes processing system 102 registering at least one of a plurality of Virtual Internet Protocol Addresses (VIPAs) to each of a plurality of Open Systems Adapters (OSAs). Registration means that the OSA interface of the network adapter will send gratuitous ARP packets and respond to ARP requests for the registered VIPA address. In box 204, method 200 includes distributing inbound data among the plurality of network adapters by each of the plurality of network adapters using Address Resolution Protocol (GRP) (gratuitous and responding). Now refer to Figure 3 , Figure 4 and Figure 5 Describe the features and functions of boxes 202 and 204.

[0026] refer to Figure 3 As an example, a block diagram of a processing system 300 with four open system adapters (i.e., network adapter 302, network adapter 304, network adapter 306, and network adapter 308) is depicted. The processing system 300 also includes seven virtual IP addresses (i.e., VIPA 310, VIPA 312, VIPA 314, VIPA 316, VIPA 318, VIPA 320, and VIPA 322), which are registered to network adapters 302, 304, 306, and 308 as shown. In this example, according to one or more embodiments described herein, VIPA is registered based on round-robin registration. That is, VIPA 310 is assigned to network adapter 302, then VIPA 312 is registered to network adapter 304, VIPA 314 is registered to network adapter 306, and VIPA 316 is registered to network adapter 308. Once each network adapter has a VIPA registered to it, the polling registration of additional VIPAs is repeated: VIPA 318 is registered to network adapter 302, VIPA 320 is registered to network adapter 304, and VIPA 322 is registered to network adapter 306.

[0027] According to another embodiment, byte count registration is performed. Byte count registration begins with polling registration (see...). Figure 3Then, the inbound byte count is measured at set time intervals. After the set time intervals, the inbound byte count for each OSA is compared. For example, if the difference between the totals exceeds a threshold, a rebalancing is initiated. During rebalancing, one or more VIPAs can move their registrations to different network adapters, thus more evenly balancing the VIPA's intra-byte count across network adapters. In some examples, the inbound byte count may take into account non-VIPA packets. In some examples, moving a VIPA causes the network adapter it moves to to perform gratuitous ARPs, causing the VIPA's inbound traffic to start flowing to it instead of its previous owner.

[0028] Figure 4 and Figure 5 A block diagram of a processing system 400 with four open system adapters (i.e., network adapter 402 / 502, network adapter 404 / 504, network adapter 406 / 506, and network adapter 408 / 508) is shown together. Figure 3 The example is similar; first, register using the polling registration method described here. Figure 4 The network adapter in the example. However, in this example, inbound data for each of VIPA 410, VIPA 412, VIPA 414, VIPA 416, VIPA 418, VIPA 420, and VIPA 422 is monitored at set time intervals (e.g., 20 seconds, 45 seconds, 1 minute, 2 minutes, 5 minutes, etc.).

[0029] In other words, such as Figure 2 As shown in block 204, method 200 includes processing system 102 distributing inbound data among a plurality of OSAs (i.e., network adapters 402 / 502, 404 / 504, 406 / 506, 408 / 508). While inbound data is distributed among each of the plurality of OSAs, processing system 102 monitors how much inbound data is received at each VIPA (e.g., VIPA 410, VIPA 412, VIPA 414, VIPA 416, VIPA 418, VIPA 420, VIPA 422). Figure 4 and Figure 5 In this context, the inbound data volume (i.e., inbound byte count) is determined and displayed for each VIPA. After a set time interval (which can be adjusted), the VIPA can re-register with other network adapters to provide a balanced load for each network adapter. For example, as... Figure 4As shown, network adapter 406 has two registered VIPAs: VIPA 414 (with an inbound byte count of 600MB of inbound data) and VIPA 422 (with an inbound byte count of 300MB of inbound data). As can be observed, these represent the two VIPAs with the largest inbound byte counts. As a result, network adapter 406 is overloaded relative to network adapters 402, 404, and 405. Therefore, Figure 4 VIPA instances can be re-registered based on their respective inbound byte counts to balance inbound data, such as Figure 5 As shown, in some examples, re-registration occurs based on the total amount of incoming data received (e.g., per 1 GB), time, network conditions, detected fault conditions, and other triggers.

[0030] According to one or more embodiments described herein, each of the plurality of network adapters resides on a public Internet Protocol stack. Furthermore, in some examples, each of the plurality of network adapters is configured on a public subnet or virtual local area network, such as Figure 3 , Figure 4 and Figure 5 As shown.

[0031] It is understood that one or more embodiments described herein can be implemented in conjunction with any other type of computing environment now known or to be developed in the future. For example, Figure 6 A block diagram of a processing system 600 for implementing the techniques described herein is shown. In an example, the processing system 600 has a processing device 602, which may include one or more central processing units, such as CPU 604, CPU 606, CPU 608, etc. (collectively or generally referred to as processors, processing devices, and / or multiple processing devices). In various aspects of this disclosure, the processing device 602 may include a Reduced Instruction Set Computer (RISC) microprocessor. In some examples, the processing device 602 and / or CPU 604, CPU 606 and / or CPU 608 may include multiple processing cores for executing instructions simultaneously / concurrently. The processing device 602 is coupled to system memory (e.g., random access memory RAM 612) and various other components via a system bus 620. A read-only memory ROM 610 is coupled to the system bus 620 and may include a basic input / output system (BIOS) that controls certain basic functions of the processing system 600.

[0032] Further described are the input / output (I / O) adapter 614 and network adapter 616 coupled to the system bus 620.

The I / O adapter 614, hard disk 636, and storage device 638 are collectively referred to herein as mass storage 640. The operating system 642 for execution on the processing system 600 may be stored in the mass storage 640. The network adapter 616 interconnects the system bus 620 with an external network 618, enabling the processing system 600 to communicate with other such systems.

[0033] A display 632 (e.g., a display monitor) is connected to the system bus 620 via a display adapter 630, which may include a graphics adapter to improve the performance of graphics-intensive applications and video controllers. In one aspect of this disclosure, an I / O adapter 614, a network adapter 616, and / or a display adapter 630 may be connected to one or more I / O buses, which are connected to the system bus 620 via an intermediate bus bridge (not shown). Suitable I / O buses for connecting peripheral devices such as hard disk controllers, network adapters, and graphics adapters typically include common protocols such as Peripheral Component Interconnect (PCI). Additional input / output devices are shown connected to the system bus 620 via a user interface adapter 622 and a display adapter 630. A keyboard 624, a mouse 626, and a speaker 628 may be interconnected to the system bus 620 via a user interface adapter 622, which may include, for example, a super I / O chip integrating multiple device adapters into a single integrated circuit.

[0034] In some aspects of this disclosure, the processing system 600 includes a graphics processing unit 634. The graphics processing unit 634 is a specialized electronic circuit designed to manipulate and modify memory to accelerate the creation of images in a frame buffer intended for output to a display. Typically, the graphics processing unit 634 is highly efficient in manipulating computer graphics and image processing and has a highly parallel architecture, making it more efficient than general-purpose CPUs used for parallel processing of large data blocks.

[0035] Therefore, as configured herein, the processing system 600 includes processing capabilities in the form of a processing device 602, storage capabilities including system memory (e.g., RAM 612) and mass storage 640, input devices such as a keyboard 624 and a mouse 626, and output capabilities including a speaker 628 and a display 632. In some aspects of this disclosure, a portion of the system memory (e.g., RAM 612) and the mass storage 640 jointly store an operating system 642, such as the AIX® operating system from IBM, to coordinate the functionality of the various components shown in the processing system 600.
