TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of optical communication, and in particular, to a Fiber to The Room (FTTR) bandwidth allocation method, an optical gateway, and a computer-readable storage medium.BACKGROUND

[0002] With the continuous development of optical networks, bandwidth network services are evolving towards the Fixed 5th-Generation (F5G) era with 10G Passive Optical Network (PON) and Wireless Fidelity (Wi-Fi) 6 as the mainstream. Compared to previous generations of fixed access technologies, F5G offers several excellent features, such as ultra-high network access rate, all-optical connection, and excellent network experience. An F5G home private network is an extension of an optical fiber to a room based on Fiber To The Home (FTTH) to realize all-optical networking in the home, and is used in combination with the 10G PON and Wi-Fi 6 technologies to achieve gigabit coverage of the entire house and solve the problems such as insufficient Wi-Fi signal coverage and unsatisfactory rate in the room, thereby achieving safe and reliable gigabit coverage throughout the house.

[0003] FTTR can be achieved using two technical schemes: Point to Point (P2P) and Point to Multi Point (P2MP). A P2MP networking method is as follows. A wide area network (WAN) side of a P2MP optical gateway is generally a 10G PON, and a local area network (LAN) side of the P2MP optical gateway may be a Gigabit-Capable PON (GPON) or a 10G PON, which is connected to one or more optical routers through an optical splitter for networking. A WAN side of the optical router is a GPON or a 10G PON. The P2MP technical scheme offers advantages of a large number of connected devices, convenient capacity expansion, and a measured rate over one gigabit at a single point. However, it also has disadvantages, including two levels of bandwidth scheduling, uneven bandwidth allocation, and high delay, which can affect the user experience.

DETAILED DESCRIPTION

[0015] To make the objects, technical schemes, and advantages of the present disclosure clear, the present disclosure is described in further detail in conjunction with accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely used for illustrating the present disclosure, and are not intended to limit the present disclosure.

[0017] With the continuous development of optical networks, bandwidth network services are developing towards the F5G era with 10G PON and Wi-Fi 6 as the mainstream. Compared with previous generations of fixed access technologies, F5G has a series of excellent features such as ultra-high network access rate, all-optical connection, and excellent network experience. An F5G home private network is an extension of an optical fiber to a room based on FTTH to realize all-optical networking in the home, and is used in combination with the 10G PON and Wi-Fi 6 technologies to achieve gigabit coverage of the entire house and solve the problems such as insufficient Wi-Fi signal coverage and unsatisfactory rate in the room, thereby achieving safe and reliable gigabit coverage throughout the house.

[0018] FTTR can be achieved using two technical schemes: P2P and P2MP. A P2MP networking method is as follows. A WAN side of a P2MP optical gateway is generally a 10G PON, and a LAN side of the P2MP optical gateway may be a GPON or a 10G PON, which is connected to one or more optical routers through an optical splitter for networking. A WAN side of the optical router is a GPON or a 10G PON. The P2MP technical scheme has the advantages of a large number of connected devices, convenient capacity expansion, and a measured rate over one gigabit at a single point, but also has the disadvantages such as two levels of bandwidth scheduling, uneven bandwidth allocation, and high delay, affecting user experience.

[0019] In recent years, with the rapid development of smart home, Virtual Reality (VR) technology, telemedicine, and other services, telecommunication operators, home users, and enterprise users have increasingly higher requirements for the bandwidth and user experience of optical fiber access. For example, 4K video streams require a bandwidth of 30 Mbps / person, voice streams require a delay of less than 30 ms, and VR streams require a bandwidth of 50 Mbps / person and a delay of less than 15 ms. Such streams are very sensitive to bandwidth and delay. The uneven bandwidth allocation and delay problems brought about by P2MP networking have great impact on user experience.

[0020] Existing related technologies fail to provide an effective scheme to solve the above problems, and how to solve the above problems in practical applications has become a problem that needs to be solved in FTTR scenarios.

[0021] To solve the uneven bandwidth allocation and delay problems brought about by P2MP networking, embodiments of the present disclosure provide an FTTR bandwidth allocation method, an optical gateway, and a computer-readable storage medium. An optical gateway acquires a packet from an optical router; identifies a service type of the optical router according to a protocol type of the packet; determines a service requirement type according to a delay and a bandwidth requirement of the service type; analyzes a bandwidth allocation slot of an OLT and an internal delay of the optical gateway; and allocates a bandwidth to the optical router according to the service requirement type, the bandwidth allocation slot, and the internal delay. The optical gateway identifies the service requirement type of the optical router and the bandwidth allocation size and slot of the OLT, to achieve service classification and sorting of the optical router and bandwidth analysis and adjustment of the OLT. The optical gateway allocates the bandwidth to the optical router according to the service requirement type and slots of two levels of bandwidth allocation, to realize the seamless connection in the two levels of bandwidth scheduling, thereby reducing the service delay and improving bandwidth utilization. Through the active bandwidth release mechanism of the optical router, the bandwidth of the optical router can be fully utilized to improve user experience. Based on this, the present disclosure can reduce the service delay in FTTR P2MP scenarios, improve bandwidth utilization, and thereby improve user experience.

[0022] FIG. 1 is a main flowchart of an FTTR bandwidth allocation method according to an embodiment of the present disclosure. The FTTR bandwidth allocation method includes the following steps.

[0023] In a step of 101, a packet is acquired from an optical router.

[0024] In a step of 102, a service type of the optical router is identified according to a protocol type of the packet.

[0025] In a step of 103, a service requirement type is determined according to a delay and a bandwidth requirement of the service type.

[0026] In a step of 104, a bandwidth allocation slot of an OLT and an internal delay of the optical gateway are analyzed.

[0027] In a step of 105, a bandwidth is allocated to the optical router according to the service requirement type, the bandwidth allocation slot, and the internal delay.

[0028] It can be understood that an optical gateway acquires a packet from an optical router; identifies a service type of the optical router according to a protocol type of the packet; determines a service requirement type according to a delay and a bandwidth requirement of the service type; analyzes a bandwidth allocation slot of an OLT and an internal delay of the optical gateway; and allocates a bandwidth to the optical router according to the service requirement type, the bandwidth allocation slot, and the internal delay. The optical gateway identifies the service requirement type of the optical router and the bandwidth allocation size and slot of the OLT, to achieve service classification and sorting of the optical router and bandwidth analysis and adjustment of the OLT. The optical gateway allocates the bandwidth to the optical router according to the service requirement type and slots of two levels of bandwidth allocation, to realize the seamless connection in the two levels of bandwidth scheduling, thereby reducing the service delay and improving bandwidth utilization. Through the active bandwidth release mechanism of the optical router, the bandwidth of the optical router can be fully utilized to improve user experience.

[0029] It can be understood that as shown in FIG. 2, the optical gateway may be connected to one or more optical routers. A service requirement type of an optical router is identified through Artificial Intelligence (AI) according to a protocol type of a packet sent by the optical router. For example, if the optical router sends a Highway Addressable Remote Transducer (HART) packet, the optical gateway may identify that the user is performing VR interaction through the optical router. If the optical router sends a multicast join packet, the optical gateway may identify that the user is watching IPTV video through the optical router. If the optical router sends a Session Initiation Protocol (SIP) packet, the optical gateway may identify that the user is making a voice call through the optical router. A single optical router may perform a single or multiple services at the same time.

[0030] It can be understood that service types may include VR, IPTV, and voice.

[0031] It can be understood that according to delay and bandwidth requirements of service types, services can be divided into four service requirement types. The service requirement types include a low-latency high-bandwidth service, a low-latency low-bandwidth service, a high-latency high-bandwidth service, and a high-latency low-bandwidth service.

[0032] It can be understood that after identifying service types of services of the optical router through AI, the optical gateway may classify the services as the corresponding service requirement types and sort the services. For example, VR interaction may be classified as a low-latency high-bandwidth service, an IPTV video may be classified as a high-latency high-bandwidth service, and a voice call may be classified as a low-latency low-bandwidth service. When the services are sorted according to latency, VR > voice > IPTV. When the services are sorted according to bandwidth requirements, VR > IPTV > voice. In the present disclosure, VR, IPTV, and voice are used as examples only, and there may also be other service requirement types, such as cloud gaming, cloud education, remote maintenance, etc.

[0033] It can be understood that while identifying the service of the optical router through AI, the optical gateway needs to record and analyze the bandwidth size and allocation slot of the OLT, and determine through calculation whether a current bandwidth allocated by the OLT meets all service requirements of the optical router connected to the optical gateway. If the bandwidth allocation slot does not meet the service requirements, the optical gateway may send a private Physical Layer Operation Administration and Maintenance (PLOAM) or Optical Network Unit (ONU) Management And Control Interface (OMCI) message to instruct the OLT to reduce a bandwidth allocation cycle or perform bandwidth allocation multiple times within one frame to reduce the delay. If the bandwidth size does not meet the service requirements, the optical gateway may send a private PLOAM or OMCI message to instruct the OLT to increase the allocated bandwidth. In a Status Reporting (SR) mode, the optical gateway may also apply for a larger bandwidth by increasing a Dynamic Bandwidth Report Upstream (DBRu) value.

[0034] It can be understood that there are two levels of bandwidth scheduling in the P2MP networking mode of the optical gateway, and the difference between time of arrival of bandwidth delivered by the OLT and time of arrival of bandwidth delivered by the optical gateway is likely to cause nonalignment between the two levels of bandwidth allocation. If the delivery of the bandwidth by the optical gateway is earlier than the delivery of the bandwidth by the OLT, a packet backlog may occur at the optical gateway, leading to an increased service delay. If the delivery of the bandwidth by the optical gateway is later than the delivery of the bandwidth by the OLT, the optical gateway may miss part of the bandwidth allocation slot of the OLT, resulting in a decrease in bandwidth utilization. The optical gateway analyzes the bandwidth allocation slot of the OLT and the internal delay of the optical gateway. The bandwidth allocation slot of the OLT includes StartTime olt , GrantSize olt , and the bandwidth allocation cycle of the bandwidth delivered by the OLT. The internal delay of the optical gateway mainly refers to a packet forwarding delay InsideDelay. A line propagation delay Propagation Delay i , of the optical router also needs to be considered. A start time StartTime i of bandwidth allocation for the optical router may be calculated by the following formula: StartTime i = StartTime olt − InsideDelay − Propagation Delay i .

[0035] It can be understood that the bandwidth allocation size GrantSize i and the bandwidth allocation cycle of the optical router are adjusted according to the service requirement type. For example, for a low-latency high-bandwidth service, GrantSize i is increased, and at the same time, the bandwidth allocation cycle is reduced or bandwidth allocation is performed multiple times within one frame to reduce the delay. For a high-latency high-bandwidth service, GrantSize i is increased, and at the same time, the bandwidth allocation cycle is increased. For a low-latency low-bandwidth service, GrantSize i is reduced, and at the same time, the bandwidth allocation cycle is reduced or bandwidth allocation is performed multiple times within one frame to reduce the delay. For a high-latency low-bandwidth service, GrantSize i is reduced, and at the same time, the bandwidth allocation cycle is increased. It should be noted that the optical gateway may further improve the bandwidth allocation precision for the optical router through AI learning based on the above bandwidth allocation policy.

[0036] As shown in FIG. 3, after step 103, the method may further include the following steps.

[0037] In a step of 1031, a bandwidth allocation priority of the service type is determined according to the service requirement type.

[0038] In a step of 1032, allocating a bandwidth to the optical router according to the service requirement type, the bandwidth allocation slot, and the internal delay includes: allocating the bandwidth to the optical router according to the bandwidth allocation priority of the service type, the bandwidth allocation slot, and the internal delay.

[0039] It can be understood that after identifying service types of services of the optical router through AI, the optical gateway may classify the services as the corresponding service requirement types and sort the services to determine bandwidth allocation priorities corresponding to the service types, and then allocate the bandwidth to the optical router according to the bandwidth allocation priorities corresponding to the service types. For example, VR interaction may be classified as a low-latency high-bandwidth service, an IPTV video may be classified as a high-latency high-bandwidth service, and a voice call may be classified as a low-latency low-bandwidth service. When the services are sorted according to latency, VR > voice > IPTV. When the services are sorted according to bandwidth requirements, VR > IPTV > voice. In the present disclosure, VR, IPTV, and voice are used as examples only, and there may also be other service requirement types, such as cloud gaming, cloud education, remote maintenance, etc.

[0040] It can be understood that the optical router also has an active bandwidth release mechanism. In the P2MP networking scenario where the optical gateway is connected to a plurality of optical routers, when an optical router does not need to send service data, the optical gateway usually still allocates an OMCI bandwidth and a service bandwidth to the optical router periodically, resulting in a waste of bandwidth. In view of this, the optical router may regularly detect whether there is service data to send. When the optical router determines that a duration during which there is no data to send reaches a time length, the optical router may send a private PLOAM or OMCI message to instruct the optical gateway to stop the allocation of the OMCI bandwidth and the service bandwidth for a period of time, or the optical gateway may instruct the optical router to switch from a normal state to an energy-saving state. When the optical router determines that there is data to send, the optical router may send a private PLOAM or OMCI message to instruct the optical gateway to resume the bandwidth allocation, or the optical gateway may instruct the optical router to switch from the energy-saving state to the normal state. The bandwidth actively released by the optical router may be allocated to other optical routers having a data service, to improve the bandwidth utilization of the optical routers.

[0041] As shown in FIG. 4, step 105 may include the following steps.

[0042] In a step of 1051, a bandwidth allocation size and a bandwidth allocation cycle of the optical router are adjusted according to the service requirement type.

[0043] In a step of 1052, a bandwidth allocation start time of the optical router is determined according to the bandwidth allocation slot and the internal delay.

[0044] It can be understood that the bandwidth allocation size N2 and the bandwidth allocation cycle of the optical router may be adjusted according to the service requirement type. In an embodiment, the bandwidth of the optical router is increased when it is determined that the service requirement type is a low-latency high-bandwidth service or a high-latency high-bandwidth service; the bandwidth of the optical router is reduced when it is determined that the service requirement type is a low-latency low-bandwidth service or a high-latency low-bandwidth service; the bandwidth allocation cycle of the optical router is reduced when it is determined that the service requirement type is a low-latency high-bandwidth service or a low-latency low-bandwidth service; and the bandwidth allocation cycle of the optical router is increased when it is determined that the service requirement type is a high-latency high-bandwidth service or a high-latency low-bandwidth service.

[0045] It can be understood that for a low-latency high-bandwidth service, N2 may be increased, and at the same time, the bandwidth allocation cycle may be reduced or bandwidth allocation may be performed multiple times within one frame; for a high-latency high-bandwidth service, N2 may be increased, and at the same time, the bandwidth allocation cycle may be increased; for a low-latency low-bandwidth service, N2 may be reduced, and at the same time, the bandwidth allocation cycle may be reduced or bandwidth allocation may be performed multiple times within one frame; and for a high-latency low-bandwidth service, N2 may be reduced, and at the same time, the bandwidth allocation cycle may be increased. It should be noted that the optical gateway may further improve the bandwidth allocation precision for the optical router through AI learning.

[0046] It can be understood that there are two levels of bandwidth scheduling in the P2MP networking mode of the optical gateway, and the difference between time of arrival of bandwidth delivered by the OLT and time of arrival of bandwidth delivered by the optical gateway is likely to cause nonalignment between the two levels of bandwidth allocation. If the delivery of the bandwidth by the optical gateway is earlier than the delivery of the bandwidth by the OLT bandwidth, a packet backlog may occur at the optical gateway, leading to an increased service delay. If the delivery of the bandwidth by the optical gateway is later than the delivery of the bandwidth by the OLT, the optical gateway may miss part of the bandwidth allocation slot of the OLT, resulting in a decrease in bandwidth utilization. The optical gateway analyzes the bandwidth allocation slot of the OLT and the internal delay of the optical gateway. The bandwidth allocation slot of the OLT includes StartTime olt , GrantSize olt , and the bandwidth allocation cycle of the bandwidth delivered by the OLT. The internal delay of the optical gateway mainly refers to a packet forwarding delay InsideDelay. A line propagation delay Propagation Delay i , of the optical router also needs to be considered. A start time StartTime i of bandwidth allocation for the optical router may be calculated by the following formula: StartTime i = StartTime olt − InsideDelay − Propagation Delay i .

[0047] The FTTR bandwidth allocation method provided in the present disclosure is further described below in conjunction with specific embodiments.

[0048] As shown in FIG. 5, in a P2MP networking scenario where the optical gateway is connected to a single optical router, the optical router has three services: VR, IPTV, and voice. The optical gateway may identify service requirement types of the services of the optical router through AI according to protocol types of packets sent by the optical router, and classify and sort the services. To realize the distinguishing and scheduling of the three services of the optical router, the optical gateway may configure three separate sending channels for the optical router.

[0049] As shown in FIG. 6, in a P2MP networking scenario where the optical gateway is connected to two optical routers, an optical router 1 has an IPTV service, and an optical router 2 has two services, i.e., VR and voice. The optical gateway may identify service requirement types of the services of the two optical routers through AI according to protocol types of packets sent by the optical routers, and classify and sort the services. To realize the distinguishing and scheduling of the two services of the optical router 2, the optical gateway may configure two separate sending channels for the optical router 2.

[0050] As shown in FIG. 7, in a P2MP networking scenario where the optical gateway is connected to two optical routers, an optical router 1 has two services, i.e., IPTV and voice, and an optical router 2 also has two services, i.e., VR and voice. The optical gateway may identify service requirement types of the services of the two optical routers through AI according to protocol types of packets sent by the optical routers, and classify and sort the services. To realize the distinguishing and scheduling of the two services of each of the optical router 1 and the optical router 2, the optical gateway may configure two separate sending channels for each of the optical router 1 and the optical router 2.

[0051] As shown in FIG. 8, there are two levels of bandwidth scheduling in the P2MP networking mode of the optical gateway. A first level of scheduling includes StartTime olt =S1, GrantSize olt =N1, and a bandwidth allocation cycle of the bandwidth delivered by the OLT. A second level of scheduling includes StartTime i =S2, GrantSize i =N2, and a bandwidth allocation cycle of the bandwidth delivered by the optical gateway. The internal delay InsideDelay of the optical gateway is a packet forwarding delay. A line propagation delay of the optical router is defined as PD i . The start time S2 of bandwidth allocation for the optical router may be calculated by the following formula: S 2 = S 1 − InsideDelay − PD i .

[0052] The bandwidth allocation size N2 and the bandwidth allocation cycle of the optical router may be adjusted according to the service requirement type. For a low-latency high-bandwidth service, N2 may be increased, and at the same time, the bandwidth allocation cycle may be reduced or bandwidth allocation may be performed multiple times within one frame; for a high-latency high-bandwidth service, N2 may be increased, and at the same time, the bandwidth allocation cycle may be increased; for a low-latency low-bandwidth service, N2 may be reduced, and at the same time, the bandwidth allocation cycle may be reduced or bandwidth allocation may be performed multiple times within one frame; and for a high-latency low-bandwidth service, N2 may be reduced, and at the same time, the bandwidth allocation cycle may be increased. The optical gateway may further improve the bandwidth allocation precision for the optical router through AI learning.

[0053] As shown in FIG. 9, an FTTR bandwidth allocation method includes the following steps.

[0054] In a step of S501, an optical gateway identifies a service requirement type of an optical router connected thereto and a bandwidth of an OLT through AI.

[0055] In a step of S502, the optical gateway determines whether the service requirement type of the optical router is a low-latency high-bandwidth service. If yes, S506 is executed; otherwise, S503 is executed.

[0056] In the step of S503, the optical gateway determines whether the service requirement type of the optical router is a low-latency low-bandwidth service. If yes, S507 is executed; otherwise, S504 is executed.

[0057] In the step of S504, the optical gateway determines whether the service requirement type of the optical router is a high-latency high-bandwidth service. If yes, S508 is executed; otherwise, S505 is executed.

[0058] In the step of S505, the optical gateway calculates slots of two levels of bandwidth allocation and allocates a high-latency small bandwidth to a corresponding service of the optical router.

[0059] In the step of S506, the optical gateway calculates slots of two levels of bandwidth allocation and allocates a low-latency large bandwidth to a corresponding service of the optical router.

[0060] In the step of S507, the optical gateway calculates slots of two levels of bandwidth allocation and allocates a low-latency small bandwidth to a corresponding service of the optical router.

[0061] In the step of S508, the optical gateway calculates slots of two levels of bandwidth allocation and allocates a high-latency large bandwidth to a corresponding service of the optical router.

[0062] In a step of S509, the optical gateway further improves the bandwidth allocation precision through AI learning.

[0063] Based on this, the optical gateway identifies the service requirement type of the optical router and the bandwidth allocation size and slot of the OLT, to achieve service classification and sorting of the optical router and bandwidth analysis and adjustment of the OLT. The optical gateway allocates the bandwidth to the optical router according to the service requirement type and slots of two levels of bandwidth allocation, to realize the seamless connection in the two levels of bandwidth scheduling, thereby reducing the service delay and improving bandwidth utilization. Through the active bandwidth release mechanism of the optical router, the bandwidth of the optical router can be fully utilized to improve user experience.
