Description

SYSTEM AND METHOD FOR UNIFORM DISTRIBUTION OF ONE OR MORE

DATA PACKETS

FIELD OF THE INVENTION

[0001] The present invention relates to user plane packet processing, more particularly relates to a system and method for uniform distribution of data traffic using user plane packet processing on a multi-core computer processing unit.

BACKGROUND OF THE INVENTION

[0002] Exchange of information between end-user devices and network infrastructure is facilitated through the use of packets in current telecommunications networks. These packets contain data, such as voice, video, and other forms of digital information, which are transmitted over the network to reach their intended destinations.

[0003] Further to the current, network architectures are designed to handle different types of data traffic, such as control plane traffic and user plane traffic. The control plane is responsible for managing signaling and control functions, while the user plane is responsible for the transmission of user data packets.

[0004] The emergence of 5th Generation (5G) networks has increased the demand for high-speed, low-latency communication with respect to the user data packets. To achieve the high speed and the low latency, efficient handling of user data traffic is required. Thus, the need for significant changes to the network architecture arises.

[0005] The User Plane Function (UPF) technology is configured to handle the user data traffic within 5G and beyond network architectures. Hence the evolution of the UPF plays an important role, since UPF acts as a crucial component within the 5G core network, responsible for various tasks, including packet forwarding, traffic management, quality of service (QoS) enforcement, and network slicing. Further the User Plane Function (UPF) enables efficient data handling, supports diverse service requirements, and ensures a seamless user experience in highly dynamic and heterogeneous network environments.

[0006] Further the UPF in a service provider is configured to host multiple user/UE session and it applies different policies (rate limit, barring, quota, forwarding policies etc) on user packets flowing through the network. UPF in case of such service provider performs inter networking between the 5G network and the data network, and may have N3 interface defined towards gNodeB and N6 interface defined towards the data network. For UPF, running on a multi-core CPU/processor, to optimize the performance, multiple Rx queues are configured which are associated with the multiple CPU cores. The network interface card (NIC) receives the uplink/downlink traffic and if the default 5-tuple RSS based packet distribution is configured, which uses source IP, destination IP, source port, destination port, protocol in deciding that on which Rx queue the packet will land to, and based on that classifies/distributes the traffic to the Rx queues. This leads to packets from the same user/UE landing onto different Rx queues in downlink and all traffic from the same gNodeB landing onto the same Rx queue. That leads to a skewed load balancing and also impacts performance as it reduces cache localization and efficiency, reduced scalability across the CPU cores and moreover the control plane data plane synchronization requires locking all the data plane cores resulting in a sub-optimal implementation.

[0007] Hence there is a need in the art to further optimize the handling of requests and queries received by the UPF, for uniform distribution of data traffic. In particular, for uniform distribution of one or more data packets.

[0038] FIG. 2 is an exemplary block diagram of the system 108 for uniform distribution of one or more data packets, according to one or more embodiments of the present invention.

[0039] As per the illustrated embodiment, the system 108 includes one or more processors 202, a memory 204, a user interface 206, and a database 208. For the purpose of description and explanation, the description will be explained with respect to one processor 202 and should nowhere be construed as limiting the scope of the present disclosure. In alternate embodiments, the system 108 may include more than one processors 202 as per the requirement of the network 106. The one or more processors 202, hereinafter referred to as the processor 202 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, single board computers, and/or any devices that manipulate signals based on operational instructions.

[0040] As per the illustrated embodiment, the processor 202 is configured to fetch and execute computer-readable instructions stored in the memory 204. The memory 204 may be configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed to create or share data packets over a network service. The memory 204 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as disk memory, EPROMs, FLASH memory, unalterable memory, and the like.

[0041] In an embodiment, the user interface 206 includes a variety of interfaces, for example, interfaces for a graphical user interface, a web user interface, a Command Line Interface (CLI), and the like. The user interface 206 facilitates communication of the system 108. In one embodiment, the user interface 206 provides a communication pathway for one or more components of the system 108. Examples of such components include, but are not limited to, the UE 102 and the database 208.

[0042] The database 208 is one of, but not limited to, a centralized database, a cloud-based database, a commercial database, an open-source database, a distributed database, an end-user database, a graphical database, a No-Structured Query Language (NoSQL) database, an object-oriented database, a personal database, an inmemory database, a document-based database, a time series database, a wide column database, a key value database, a search database, a cache databases, and so forth. The foregoing examples of database 208 types are non-limiting and may not be mutually exclusive e.g., a database can be both commercial and cloud-based, or both relational and open-source, etc. [0043] In order for the system 108 for uniform distribution of data traffic such as one or more data packets, the processor 202 includes one or more modules. In one embodiment, the one or more modules includes, but not limited to, a receiving unit 210, a retrieving unit 212, a hashing unit 214, a generating unit 216, a mapping unit 218 and a transmitting unit 220 communicably coupled to each other for uniform distribution of one or more data packets.

[0044] The receiving unit 210, the retrieving unit 212, the hashing unit 214, the generating unit 216, the mapping unit 218 and the transmitting unit 220 in an embodiment, may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor 202. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor 202 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processor may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the memory 204 may store instructions that, when executed by the processing resource, implement the processor. In such examples, the system 108 may comprise the memory 204 storing the instructions and the processing resource to execute the instructions, or the memory 204 may be separate but accessible to the system 108 and the processing resource. In other examples, the processor 202 may be implemented by electronic circuitry.

[0045] In one embodiment, the receiving unit 210 of the system 108 is configured to receive one or more data packets from one or more UE 102. The one or more data packets is one of an uplink data packet and a downlink data packet. The uplink data packet refers to the data transmitted from the UE 102 to the network 106. The uplink data packet includes, but not limited to, video uploads, file uploads, text messages, sensor data from loT devices, Voice over Internet Protocol (VoIP) calls, online gaming, web requests, GPS location updates. The downlink data packet refers to the data transmitted from the network 106 to the UE 102. The downlink data packet includes, but not limited to, web pages, streaming video, software updates, app downloads, emails and attachments, social media feeds, voice and video calls, realtime data feeds. The uplink data packet is received via a first interface and the downlink data packet is received via a second interface. The first interface is an N3 interface and the second interface is an N6 interface.

[0046] The N3 interface is a logical interface primarily responsible for carrying user plane data traffic between an Access and Mobility Management Function (AMF) and a User Plane Function (UPF). The AMF is responsible for managing mobility and session-related information for the UE 102, while the UPF handles the routing, forwarding, and management of user plane data packets. The N3 interface includes, but not limited to, user plane tunneling, Quality of Service (QoS) enforcement, charging and billing, and session management. The N6 interface enables communication and data exchange between the UPF and the AMF.

[0047] Upon receiving the one or more data packets, a retrieving unit 212 is configured to retrieve an Internet Protocol (IP) address of the one or more data packets. The IP address of the one or more data packets is retrieved from a source address of a Protocol Data Unit (PDU) of an IP header and a destination address of the IP header.

[0048] The IP address is a unique numerical label assigned to each UE 102 connected to the network 106 that uses the IP for communication. The source address of the PDU of the IP header is the IP address assigned to the UE 102 for initiating the communication. The source address identifies where the PDU originates in the network 106. The PDU refers to the unit of data that is exchanged between different protocol layers. The destination address of the IP header is the IP address of the intended recipient UE 102. [0049] If the one or more data packets is the uplink data packet, the retrieving unit 212 is configured to retrieve the IP address of the one or more data packets from the PDU of the IP header. If the one or more data packets is the downlink data packet, the retrieving unit 212 is configured to retrieve the IP address of the one or more data packets from the destination address of the IP header.

[0050] Upon retrieving the IP address of the one or more data packets, the hashing unit 214 is configured to perform hashing operation on the IP address of each of the one or more retrieved IP addresses. The hashing unit 214 performs hashing operation on the IP address of each of the one or more retrieved IP addresses to receive a hash value 406 of the IP address of each of the one or more retrieved IP addresses. The hashing is a technique used to map data of arbitrary size to fixed-size values and is often used to efficiently distribute packets across multiple processing queues or paths.

[0051] Upon receiving the hash value 406 of the IP address of each of the one or more retrieved IP addresses, the generating unit 216 is configured to generate a query list based on the hash value 406. The query list includes a hash to an Rx queue table. The hash value 406 is a cryptographic representation generated by applying a hash function 404 to the IP address. The hash function 404 converts the IP address into a fixed-length string of characters, typically in hexadecimal format. The Rx queue is a receiving queue used to temporarily store one or more data packets until they can be processed. The hash to Rx queue table 408 is essentially a lookup table that maps the hash value 406 of certain packet attributes such as source/destination IP address, source/destination port, protocol type to specific Rx queues.

[0052] Upon generating the query list, the mapping unit 218 is configured to map the at least one core from the plurality of cores 410. By doing so, the mapping unit 218 distributes one or more data packets across the plurality of data cores. The at least one core refers to the CPU core (Central Processing Unit core). The CPU core refers to the individual processing units within a CPU (processor) chip. The CPU cores execute instructions and perform calculations for various tasks, including both control plane and data plane functions in the network 106. The CPU cores are found in the various network components such as routers, switches, or base stations. The CPU cores handle a variety of tasks, including packet forwarding, routing, management plane operations, control plane functions, and more.

[0053] The mapping unit 218 is configured to map the at least one core from the plurality of cores 410 based on a redundancy check. The redundancy check is performed on processing history of previously received data packets. The previously received data packets include the one or more data packets previously received from the UE 102. Upon mapping the at least one core from the plurality of cores 410, the transmitting unit 220 is configured to transmit the queries from the query list to the at least one mapped core of the plurality of cores 410. By doing so, the system 108 improves the processing capacity, performance and throughput of the processor 202 and able to process more data packets per second.

[0054] FIG. 3 describes a preferred embodiment of the system 108 of FIG. 2, according to various embodiments of the present invention. It is to be noted that the embodiment with respect to FIG. 3 will be explained with respect to the first UE 102a and the system 108 for the purpose of description and illustration and should nowhere be construed as limited to the scope of the present disclosure.

[0055] As mentioned earlier in FIG. 1, each of the first UE 102a the second UE 102b, and the third UE 102c may include an external storage device, a bus, a main memory, a read-only memory, a mass storage device, communication port(s), and a processor. The exemplary embodiment as illustrated in FIG. 3 will be explained with respect to the first UE 102a without deviating from the scope of the present disclosure and the limiting the scope of the present disclosure. The first UE 102a includes one or more primary processors 302 communicably coupled to the one or more processors 202 of the system 108. [0056] The one or more primary processors 302 are coupled with a memory unit 304 storing instructions which are executed by the one or more primary processors 302. Execution of the stored instructions by the one or more primary processors 302 enables the first UE 102a to transmit the one or more data packets to the one or more processers 202.

[0057] As mentioned earlier in FIG. 2, the one or more processors 202 of the system 108 is configured for uniform distribution of one or more data packets. As per the illustrated embodiment, the system 108 includes the one or more processors 202, the memory 204, the user interface 206, and the database 208. The operations and functions of the one or more processors 202, the memory 204, the user interface 206, and the database 208 are already explained in FIG. 2. For the sake of brevity, a similar description related to the working and operation of the system 108 as illustrated in FIG. 2 has been omitted to avoid repetition.

[0058] Further, the processor 202 includes the receiving unit 210, the retrieving unit 212, the hashing unit 214, the generating unit 216, the mapping unit 218 and the transmitting unit 220. The operations and functions of the receiving unit 210, the retrieving unit 212, the hashing unit 214, the generating unit 216, the mapping unit 218 and the transmitting unit 220 are already explained in FIG. 2. Hence, for the sake of brevity, a similar description related to the working and operation of the system 108 as illustrated in FIG. 2 has been omitted to avoid repetition. The limited description provided for the system 108 in FIG. 3, should be read with the description as provided for the system 108 in the FIG. 2 above, and should not be construed as limiting the scope of the present disclosure.

[0059] FIG. 4 is an exemplary block diagram of an architecture 400 of the system 108 for uniform distribution of one or more data packets, according to one or more embodiments of the present invention. [0060] In an embodiment, the UE 102 is configured to transmit one or more data packets to a User Plane Function (UPF) 402. The UPF is responsible for performing several important functions, such as packet forwarding, quality of service (QoS) enforcement, and traffic filtering. The one or more data packets is one of the uplink data packet and the downlink data packet. The uplink data packet is received via the first interface and the downlink data packet is received via the second interface. The first interface is the N3 interface and the second interface is the N6 interface.

[0061] The UPF 402 includes the retrieving unit 212, hash function 404, hash value 406, hash to Rx queue table 408 and plurality of cores 410 communicably coupled to each other.

[0062] The retrieving unit 212 upon receiving the one or more data packets, the IP address for the uplink data packet is identified and retrieved from the PDU IP header. Similarly, the IP address for the downlink data packet is identified and retrieved from the destination address of IP header. Upon identifying and retrieving the IP address, hash function 404 performs hashing on the IP address retrieved for the uplink data packet and the downlink data packet. Upon performing hash function 404 on the retrieved IP address, a hash value 406 is obtained for the uplink data packet and the downlink data packet.

[0063] Upon obtaining the hash value 406, the query list is generated based on the hash value. The query list comprises hash to Rx queue table 408. Further, to create the query list, the hashing value of the uplink request and the downlink request are mapped with at least one core from the plurality of core 410. The mapping of the hashing value with the at least one core from the plurality of core 410 is based on a redundancy check. The redundancy check is performed by determining previous request received from the UE 102 and the at least one core from the plurality of core 410 that processed the previous request. In an embodiment, the memory 204 comprises El cache, L2 cache, and L3 cache to perform caching of information received from the uplink, and downlink. The LI cache, L2 cache and L3 cache may enable providing information pertaining to the earlier request and also assist the at least one core from the plurality of core 410 by providing information on the previous request.

[0064] Upon caching the information, the queries from the query list are processed by the at least one core from the plurality of core 410. In one embodiment, mapping of the repetitive query to the same core is referred to as pinning. Thereby enabling higher throughput using the same conventional core from the multi-core processor. Further since the LI cache, L2 cache, and L3 cache usually store processing data of the query, using the already stored processing data by the same core reduces processing time for the query.

[0065] FIG. 5 is a signal flow diagram for uniform distribution of one or more data packets, according to one or more embodiments of the present invention.
