- IP Internet Protocol
- MPLS Multi-Protocol Label Switching
- SRv6 Segment Routing over IPv6
- point-to-point network paths with different characteristics can be constructed, such as low latency and large bandwidth. Further building on the above capabilities and combining them with a bandwidth resource reservation mechanism can realize network-wide slicing capabilities, enabling a physical network to be virtualized into multiple logical slices, with each slice occupying different resources, thereby achieving multi-point to multi-point differentiated network connections.
- IP backbone network already has flexible differentiated service capabilities, there are many different approaches to the coordination of applications and network capabilities.
- the first approach is to classify traffic based on application characteristics and then direct different traffic to specific network paths (MPLS or SRv6).
- MPLS MPLS
- SRv6 specific network paths
- the first solution uses an access control list (ACL) based on layer 3 and layer 4 header information to classify application types.
- ACL access control list
- the traffic is classified by matching the source IP, destination IP, protocol type, source port, and destination port five-tuples of the traffic through the ACL, and then directed to a specific low-latency or high-bandwidth tunnel/slice.
- the hardware chips of routers and switches support ACL, so high-performance forwarding can be achieved.
- ACL requires manual maintenance of the five-tuple characteristics of the application and configuration on the network device in the form of ACL commands. After the ACL classifies the flow, it specifies the next one for the flow, thereby directing the flow to the specified SRv6/MPLS tunnel or slice.
- the second solution uses deep packet inspection (DPI) based on seven-layer content information to classify application types.
- DPI deep packet inspection
- DPI needs to identify the packet encapsulation, reassemble a series of packets into application data, and then classify them according to the characteristics of these application data.
- DPI usually describes application characteristics in the form of regular expressions. It cannot be processed by the routing chip and can only be processed by the CPU. Common application characteristics include URLs, HTML tags, text, etc. Similar to ACL, application characteristics need to be manually maintained and configured on network devices, and it also needs to be able to reassemble multiple packets into application data.
- DPI classifies the flow, it specifies the next one for the flow, thereby introducing the flow into the specified SRv6/MPLS tunnel or slice.
- the second school of thought is to use explicit type information.
- the network edge service access point PE identifies the application information explicitly carried in the message and then maps this type of message to the network tunnel/slice.
- APN Application-Aware Networking additionally defines application information description in the message.
- APN utilizes the extension headers (Extension Headers) that come with IPv6 data messages, such as the programmable space of the Hop-by-Hop Options Header (HBH) and the Destination Options Header (DOH).
- Extension Headers Extension Headers
- HBV Hop-by-Hop Options Header
- DOH Destination Options Header
- APN requires the message to carry application information so that network devices can directly identify the application information. After classifying the flow based on the APN information, it specifies the next one for the flow, thereby introducing the flow into the specified SRv6/MPLS tunnel or slice.
- APN needs to explicitly carry the APN ID in the message in an unencrypted manner.
- APN ID marking On the one hand, it requires the application to be willing to mark the APN ID, and on the other hand, it requires a unified organization to centrally allocate APN IDs to applications. According to the location of the APN ID marking on the traffic, it is divided into two methods: end-side marking and network marking. Considering that the early application side does not have the relevant capabilities, network boundary service access point marking can be used first. As the ecosystem matures, more services can carry APN IDs independently to further improve the accuracy of service perception.
- FIG. 1 is a schematic diagram of an APN header in related art.
- the APN header includes APN identification information and APN parameter information.
- the APN header can be used in different data planes.
- the APN header format may include:
- APN parameter information (APN-Para).
- APN ID is used to identify service attributes, indicating that messages carrying the same identifier will be given the same treatment. It specifically includes the following information: APP Group ID, which is used to identify the application group to which the message belongs and has a variable length; USER Group ID, which is used to identify the user group to which the message belongs and has a variable length.
- APN parameter information is a parameter related to network performance requirements.
- the specific parameters are defined by APN-Para-Type, and the length of each APN parameter is 32 bits.
- APN-Para is transmitted together with the APN ID information to describe the required network connection requirements. It specifically includes the following information: Bandwidth, which indicates the bandwidth requirement of the application, in Mbit/s; Delay, the first 8 bits are reserved and must be set to 0 when sending and must be ignored when receiving.
- the last 24 bits indicate the delay requirement, in ms, encoded as an integer value; Jitter, the first 8 bits are reserved and must be set to 0 when sending and must be ignored when receiving, and the last 24 bits indicate the delay variation requirement, in ms, encoded as an integer value; Packet Loss Ratio, the first 8 bits are reserved and must be set to 0 when sending and must be ignored when receiving, and the last 24 bits indicate the packet loss rate per second, which is the maximum packet loss rate allowed by the system.
- the APN header (including the APN identifier and required parameters) can be encapsulated in the IPv6 packet extension header. Specifically, the following methods can be used:
- Hop-by-Hop Options Header The APN header can be carried as a new option of the Hop-by-Hop Options Header. By using the information carried by the Hop-by-Hop Options Header, each node on the path can read it.
- DOH Destination Options Header
- Segment Routing Header The APN header can also be placed in the Segment Routing Header, as a type of Segment Routing Header TLV, immediately following the Segment List.
- the information carried in the Segment Routing Header can be read by a specific segment on the SRv6 path.
- the application information carried by data packets in the APN network can indicate the application (class) to which the data packet belongs, the user (group) information using the application (class), the key flows in the application (for example, action instructions in cloud games, etc.), SLA requirements or network performance requirement parameters (for example, bandwidth, latency, jitter, packet loss rate, etc.).
- the third school of thought is to directly open the network connection and let the application call it.
- the network connection service is abstracted by binding segment identifiers (BSID, Binding SID).
- BSID binding segment identifiers
- the IP backbone network abstracts the paths between PEs into BSIDs with different service capabilities, such as low latency, large bandwidth, and low packet loss, and directly compiles different BSIDs into the path list at the terminal.
- This method requires the BSID to be made public, and the BSID is shared by multiple services. Once it is made public, it is easy to cause security issues such as network attacks and BSID bandwidth being misused.
- the BSID is a shared resource, once it is deactivated, it will affect the business, so it cannot eliminate the security risks by deactivating it.
- ACL and DPI are only applicable in specific scenarios.
- ACL User Datagram Protocol
- DPI can address the problem of ACLs failing to accurately identify applications, but its deployment also has significant limitations.
- DPI requires CPU processing, consuming significant processing power.
- DPI cannot handle encrypted packets, while the vast majority of Internet traffic, such as HTTPS, is encrypted. Therefore, large-scale application is difficult.
- APN APN
- the first issue is APN ID privacy and security. If traffic can be identified through APN, there is a risk of traffic hijacking and analysis, which can make users less motivated to use APN.
- APN ID management is extremely difficult. APN IDs require unified management across the entire network, and different applications need to be distinguished by different values.
- the Internet lacks a centralized application APN ID registration and management mechanism, and with the large number of new applications appearing daily, implementation is difficult.
- the third issue is APN ID leakage. Messages may be intercepted during forwarding, allowing non-accelerated users to obtain this APN ID. This APN ID can then be included in messages sent by non-accelerated users, illegally achieving acceleration.
- the user edge device obtains a first ARN identifier; the first ARN identifier represents the calling relationship between the application and the network capability and/or the capability open to the application by the network; the first IP packet is marked based on the first ARN identifier to generate a second IP packet; and the second IP packet is sent.
- FIG. 2 is a schematic diagram of an implementation flow of an information processing method according to an embodiment of the present disclosure, which is applied to a user edge device.
- the user edge device may be a client router, an SD-WAN CPE, a cloud gateway, or an application.
- the method includes steps 201 to 203:
- Step 201 Obtain a first ARN identifier; the first ARN identifier represents the calling relationship between the application and the network capability and/or the capability opened by the network to the application.
- the network capability may refer to network resources, which may specifically include paths or slices, and the path may be understood as a tunnel.
- the service type of the path or slice includes but is not limited to one of the following:
- the calling relationship between the application and the network capability may include but is not limited to one of the following:
- the application's call to low-latency network capabilities can also be described as the application's call to low-latency path or slice services.
- the application's call to high-bandwidth network capabilities can also be described as the application's call to high-bandwidth path or slice services.
- the application's call for low-packet-loss network capabilities can also be described as the application's call for low-packet-loss path or slice services.
- network resources which may specifically include paths or slices, and the paths may be understood as tunnels.
- Step 202 Mark the first IP packet based on the first ARN identifier to generate a second IP packet.
- the first IP packet may be an IPv6 packet.
- marking the first IP packet based on the first ARN identifier includes:
- the first information is used to indicate whether to convert the original content in the flow label field into the first ARN identifier.
- the first information may also be described as an escape character.
- the first information may be located in the highest bit of the traffic class field.
- the flow label (Flow Label) field is reused, and the highest bit (escape character) of the traffic type field (tc, traffic class) is used to indicate whether to escape. If the bit is 1, the original content in the flow label field is escaped to the first ARN ID; otherwise, no escape is performed.
- marking the first IP packet based on the first ARN identifier includes:
- the first ARN identifier is written into the source address field in the header of the first IP packet.
- the extended header may refer to a DOH, HBH, or SRH header.
- the ARN ID field is introduced into the first IP packet to glue the application and the network together through the first ARN ID.
- the first ARN ID not only expresses the calling relationship between the application and the network, but also expresses the application's requirements for the network path or slice, such as path constraints such as latency, packet loss, jitter, and bandwidth.
- obtaining the first ARN identifier includes:
- the first ARN identifier is allocated by the controller to the user edge device based on user information, application information and network service information.
- the network service information may include quality of service (QoS), network interface, etc.
- QoS quality of service
- network interface etc.
- the service system calls the controller interface based on the service type subscribed by the user. After receiving the user's network service subscription request, the controller assigns the first ARN identifier to the user edge device.
- the controller may allocate the first ARN identifier to the user edge device based on user information, application information, and network service information.
- the first ARN ID can be any integer that satisfies a one-to-one correspondence between ⁇ user, application, network service> and ARN ID. Specifically, it can be generated using a random function, or generated from small to large, or from large to small.
- the controller assigns the first ARN ID to the user edge device, it can also manage the lifecycle of the first ARN identifier, specifically including:
- revocation refers to the controller deleting the relevant ARN ID information at the user and network edge.
- the report of loss also corresponds to the cancellation of the related ARN ID.
- reissue means that an ARN ID needs to be regenerated.
- aging means that the corresponding APN service has a time limit, and the corresponding ARN ID will be automatically revoked after the time expires.
- the extension refers to extending the service time of the ARN ID.
- Step 203 Send the second IP message.
- the second IP packet may be sent to a network edge device.
- the network edge device is a BRAS/BNG for home users, a router connected to the core network for wireless users, and a PE for accessing user dedicated lines for government and enterprise users.
- the network edge device parses the second IP packet to obtain the first ARN identifier carried in the first IP packet; and verifies the legitimacy of the first ARN identifier.
- the validity of the first ARN identifier is verified in the following two situations:
- the second IP packet is mapped to the corresponding path or slice based on the first ARN identifier.
- the first operation is performed.
- the first operation includes one of the following:
- the user edge device may carry the first user information in the second IP message, so that the network edge device can verify the first ARN identifier.
- sending the second IP message includes:
- a user edge device obtains a first ARN identifier; the first ARN identifier represents the calling relationship between the application and the network capability and/or the capability opened by the network to the application; a first IP packet is marked based on the first ARN identifier to generate a second IP packet; and the second IP packet is sent.
- the first ARN identifier represents the calling relationship between the application and the network capability and/or the capability opened by the network to the application
- the user or application does not directly call the network capability, but calls the network capability through the first ARN identifier, so that the network will not see the relevant information of the user or application.
- the network does not directly open the capability to the user, but opens the capability through the first ARN identifier, so that the user will not see the service information of the network, thereby improving security while providing application collaborative network capabilities.
- the disclosed embodiments use ARN identification.
- users/applications cannot directly call the network path, but must call network services through the intermediate layer ARN.
- the network cannot see user application information, but only sees the intermediate layer ARN.
- APN directly carries application and user information, which the network directly sees.
- BSID directly opens network capabilities to users, and users directly see network service information.
- ARN ID does not directly use the network connection identifier, such as BSID or SID, but uses an ARN ID independent of BSID.
- the value range of ARN ID in the message is random for different users.
- the controller can map a user network demand contract to different ARN ID values for different devices, and set it to be device-valid rather than globally valid. Different ARN ID values can be different for different devices. Therefore, it carries neither network privacy information nor user privacy information.
- ARN IDs In terms of maintainability, network capabilities expressed through ARN IDs are independent of application changes, eliminating the frequent configuration changes associated with rapid application iterations and facilitating the planned opening of network capabilities. Furthermore, because ARN IDs correspond one-to-one with user-paid contracts, configuration information can be easily embedded into business processes, eliminating the need to convert contracts into ACL quintuples or APN IDs.
- the ARN ID sits between applications and the network, and like a contract, has a lifecycle, with operations such as creation, destruction, expiration, renewal, and verification. If ARN ID information is discovered to be leaked, it can be quickly reported lost and a new ARN ID requested without impacting other users' services. Furthermore, messages entering the SR network can be correctly mapped to the corresponding SR Policy path based on the ARN ID, even without carrying a BSID/SID. Even when carrying a BSID/SID, the ARN ID can be used to verify the legitimacy of the BSID/SID call to the network. This resolves security issues.
- ARN IDs can be divided into two categories: global ARN IDs, which have the same lifecycle across all sites, but can be different on different devices at different sites; and localized ARN IDs, which are tailored to the local needs of individual users and have independent lifecycles. Customers with localized ARN IDs must carry them in messages. Because ARN ID values are not required to be the same globally, coordination requirements are minimized.
- the network edge device is a BRAS/BNG for home users, a router connected to the core network for wireless users, and a PE for accessing user dedicated lines for government and enterprise users.
- the method includes step 301:
- Step 301 Receive a second IP message

- the 7th bit of the traffic type field (TC) needs to be set to 1 to indicate that the current Flow Label carries the ARN ID.
- the type field needs to be additionally defined to indicate that the 32-bit carries the ARN ID.
- Step 603 The user edge device sends the second IP packet to the network edge device.
- the network edge device is BRAS/BNG for home users, a router connected to the core network for wireless users, and a PE for accessing user dedicated lines for government and enterprise users.
- Step 604 The network edge device parses the second IP packet to obtain the first ARN identifier; and verifies the legitimacy of the first ARN identifier.
- the validity of the first ARN identifier is verified according to a preset data table, wherein the preset data table stores a preset correspondence between user information and ARN identifiers, wherein the user information may include a user identifier corresponding to the user, source address information, or link information.
- the ARN ID verification table i.e., the preset data table

- the correspondence between the first user information and the first ARN identifier is not found in the preset data table, it is determined that the first ARN identifier is illegal.
- the first user information may be obtained through the inbound interface link or the source IP address in the second IP packet.
- Step 605 When the ARN identifier is verified to be legal, the second IP packet is mapped to a corresponding path or slice based on the first ARN identifier.

- the second IP packet can be processed as follows according to the configuration:
- the first ARN ID is reset to 0 as configured; or,
- the second IP packet will be forwarded according to the slice and tunnel that does not contain the ARN ID.
- the network ARN ID is mainly used at network edge service access points (such as PE, BRAS/BNG).
- the business system calls the controller interface according to the service type subscribed by the user. After receiving the user's network service subscription requirements, the controller will find the corresponding network edge device (PE/BRAS/BNG) according to the locations of both ends of the connection, and create or reuse the corresponding low-latency color tunnel identifier (color) of SRv6, Multi-Protocol Label Switching (MPLS), Internet Layer 3 Protocol (IPinIP) between the PE/BRAS/BNG according to the user's low-latency requirements.
- PLS network edge device
- IPinIP Internet Layer 3 Protocol
- the controller will generate ARN ID for users, applications and network services (corresponding color), and look up the source address information or link information corresponding to the user to identify the user.
- the user (source address or link information) and ARN ID are then sent to the network edge service access point PE/BRAS/BNG and associated with the network resource slice/tunnel, thus completing the configuration of PE/BRAS/BNG on the network side.
- the controller On the user-side network, the controller locates the corresponding customer edge device (CPE/gateway) based on the user and then issues the ARN ID information. This allows users to tag the ARN ID based on the application type in subsequent applications.
- CPE/gateway customer edge device
- legitimacy verification is performed to enable the invocation of corresponding network capabilities.
- Users can also tag applications with the ARN ID through methods such as ACLs and designated links, thus including the ARN ID in user-side messages.
- network services can provide users with differentiated connections (low latency, large bandwidth tunnels/slices) through ARN ID instead of BSID/SID.
- ARN ID provides the ability to assign different values to each user, which is different from the security issues caused by multiple users sharing one BSID.
- the value of ARN ID is a number that does not explicitly carry application or user information. It can be a random number or a sequentially assigned value, so there is no problem of APN6 exposing user privacy.
- APN6 and BSID multiple ARN IDs that can be mapped to the same network capability can be aggregated into one ARN ID.
- the first ARN ID can be used together with user information for traffic billing.
- user information can be identified by link, i.e., PPPoE connection, or in PE scenarios, by source IP address or dedicated line link.
- the scope of the first ARN ID can be global or local.
- Local validity means that different ARN IDs on the device are unique; global validity means that one or more ARN IDs of a specific user within a certain range of devices can be mapped to a tunnel/slice in the network.
- ARN ID does not explicitly carry the user’s application information and each user’s ARN ID is different, this solves the user privacy problem and also solves the network security problem caused by different users sharing the BSID.
- the ARN ID is actually equivalent to the routing policy Color (directly corresponding to the Color of the SR Policy).
- the PE can obtain the user information based on the source IP, and after verifying the legitimacy of the ARN ID, it can map the ARN ID to a specific network tunnel/slice.

在对本公开实施例的技术方案进行介绍之前,先对相关技术进行介绍。
相关技术中,互联网提供尽力而为的服务,数字经济全面构筑在互联网协议(IP,Internet Protocol)网络之上。多样化的应用需求对网络能力提出更高要求,推动IP技术不断演进以满足更高的质量保障能力。和光传输网(OTN,Optical Transport Network)固定的资源分配不同,IP的本质是统计时分复用,IP网络质量依赖于路径的拥塞程度、底层光链路的误码率等。为在IP网络中提供质量保障能力,从2000年多协议标签交换(MPLS,Multi Protocol Label Switching)到当前的IPv6段路由(SRv6,Segment Routing over IPv6)技术均是以如何提供网络路径调度能力为核心,通过规划网络链路资源,可以构建具备不同特性的点到点网络路径,例如低时延、大带宽。进一步在上述能力的基础上结合带宽资源预留机制可以实现全网的切片能力,实现一张物理网络被虚拟为多个逻辑分片,每个分片占用不同资源,从而实现多点到多点的差异化网络连接。
虽然IP骨干网络内部已经具备了灵活的差异化服务能力,但是在应用和网络能力协同时,现有方案存在多种流派。
第一种流派是基于应用特征进行流量分类,然后对将不同流量引流到特定网络路径(MPLS或SRv6)上。通常根据应用识别分为2种方案:
第一种方案,采用基于三、四层头部信息的访问控制列表(ACL,Access Control List)进行应用类型分类。在网络边界业务接入点,通过ACL匹配流量的源IP、目地IP、协议类型、源端口、目的端口五元组对流量进行分类后引流到特定低时延或大带宽隧道/切片。通常路由器和交换机的硬件芯片都支持ACL,因此可实现高性能的转发。但ACL需要人工维护应用的五元组特征并以ACL命令方式配置到网络设备上。ACL进行流分类后,通过为该流指定下一条,从而实现将流引入到指定的SRv6/MPLS隧道或者切片。
第二种方案,采用基于七层内容信息的深度报文检测(DPI,Deep Packet Inspection)进行应用类型分类。为提取七层内容,DPI需要识别报文封装,将一系列报文重组后还原为应用数据,然后根据这些应用数据特征进行分类。DPI通常是以正则表达式方式描述应用特征,无法通过路由芯片进行处理,只能采用CPU处理,常见的应用特征有URL、HTML标签、文字等。和ACL类似,需要人工维护应用特征并配置到网络设备上,而且额外需要能够将多个报文重组为应用数据。DPI进行流分类后,通过为该流指定下一条,从而实现将流引入到指定的SRv6/MPLS隧道或者切片。
第二种流派是应用显式携带类型信息,网络边界业务接入点PE识别报文中显式携带的应用信息,然后将该类报文映射到网络隧道/切片上。
在报文中额外定义应用信息描述的应用感知网络(APN,Application-Aware Networking)。APN利用IPv6数据报文自带的扩展头(Extension Headers),例如,逐跳选项头(HBH,Hop-by-Hop Options Header)、目的选项头(DOH,DOH)的可编程空间。和ACL、DPI不同的是,APN要求报文携带应用信息,使得网络设备可直接识别应用信息,然后根据APN信息进行流分类后,通过为该流指定下一条,从而实现将流引入到指定的SRv6/MPLS隧道或者切片。APN需要在报文中以非加密方式显式携带APN ID,一方面要求应用愿意标记APN ID,另一方面需要一个统一的机构集中为应用分配APN ID。按照对流量标记APN ID的位置不同,分为端侧标记和网络标记两种方式。考虑到早期应用侧还不具备相关的能力,可以先采用网络边界业务接入点标记,随着生态的成熟,让更多的业务可以自主携带APN ID进一步提升业务感知的准确性。
参见图1,图1是相关技术中APN头部的示意图,如图1所示,APN头部包含APN标识信息和APN参数信息,APN头部可以在不同的数据平面中使用。
如图1所示,APN头部格式中可以包括:
APN ID;
APN参数信息(APN-Para)。
这里,APN ID用于标识业务属性,表明携带相同标识的报文都会被给予相同的处理,具体包含以下信息:APP Group ID,用于标识该报文所属的应用组,长度可变;USER Group ID,用于标识该报文所属的用户组,长度可变。
这里,APN参数信息(APN-Para)是与网络性能要求相关的参数,具体包含哪些参数由APN-Para-Type来定义,每个APN参数的长度为32bit。通过不同的参数信息组合,可以更详细的表述应用需求。APN-Para与APN ID信息一起传递,用来描述所需的网络连接要求,具体包含以下信息:Bandwidth,表示应用的带宽需求,单位为Mbit/s;Delay,前8bit保留,发送时必须设置为0,接收时必须忽略。后24bit,表示时延需求,单位为ms,编码为整数值;Jitter,前8bit保留,发送时必须设置为0,接收时必须忽略,后24bit,表示时延变化需求,单位为ms,编码为整数值;Packet Loss Ratio,前8bit保留,发送时必须设置为0,接收时必须忽略,后24bit,表示每秒的丢包率,该值是系统允许的最大丢包率。
这里,APN头(包括APN标识和需求参数)可以被封装在IPv6报文扩展头中,具体可以包括以下几种方式:
逐跳选项头(HBH):APN头可以作为逐跳选项头的一个新选项来携带,通过使用逐跳选项头携带的信息可以被路径上的每个节点读取。
目的选项头(DOH):APN头可以作为目的选项头的一个新选项来携带,通过目的选项头携带的信息可以被路径上的相应节点读取。
段路由头(SRH,Segment Routing Header):APN头也可以放在段路由头中,作为段路由头TLV的一种类型,紧跟在分段列表之后。通过段路由头携带的信息可以被SRv6路径上的指定段读取。
APN网络中数据报文所携带的应用信息可以指示数据报文所属的应用(类)、使用该应用(类)的用户(组)信息、该应用中的关键流(例如,云游戏中的动作指令等)、SLA需求或网络性能需求参数(例如,带宽、时延、抖动、丢包率等)。
第三种流派是直接开放网络连接,让应用去调用。主要在SRv6网络场景下,通过绑定段识别符(BSID,Binding SID)来抽象网络连接服务。这种方式主要应用在SD-WAN上,IP骨干网通过把PE之间的路径抽象为具备不同服务能力的BSID,例如低时延、大带宽、少丢包等类型,在终端直接把不同的BSID编入路径列表。这种方式需要对外公开BSID,且BSID被多业务公用,一旦被公开很容易引发网络攻击、BSID带宽被冒用等安全问题,而且由于BSID是共享资源,一旦停用会影响业务,所以无法通过停用来消除安全隐患。
现有两种流派存在不同问题导致均无法在现网广泛应用,
对于流派一,ACL、DPI仅特定场景有应用。
ACL方式存在的主要问题是:越来越多的应用共享某一个用户报文协议(UDP,User Datagram Protocol)端口,已经不能直接根据UDP端口来识别区分应用。过于复杂的ACL也将影响设备对应用报文的转发性能,并产生大量“僵尸”表项。尤其是应用发生变化导致配置失效时,ACL的配置也需要进行相应更新,维护工作将极度复杂。
DPI方式可以解决ACL无法精确识别应用的问题,但部署应用也存在重要的限制。首先DPI需要CPU处理,要消耗大量的处理能力;其次DPI不能处理加密报文而互联网绝大多数流量均为加密流量,例如HTTPS。因此难以大规模应用。
对于流派二,APN方式存在如下无法解决核心问题,导致用户使用意愿不足、网络安全风险高,因此多年以来一直难以推进部署:
问题一,APN ID隐私安全问题。如果流量通过APN可被识别,则也存在流量被劫持和分析的风险,导致用户使用APN动力不足。
问题二,APN ID的管理极度困难。APN ID要求全网统一管理,不同应用需要通过不同的值进行区分。而互联网并无集中的应用APN ID注册管理机制,且每天都会产生大量新的应用,难以落地。
问题三,APN ID泄露问题。报文在转发过程中可能会被侦听,非加速用户可以获得此APN ID,从而在非加速用户发出的报文中也携带该APN ID,非法获得加速效果。
问题四,网络攻击风险。APN报文特征明显且容易攻击,黑客可以针对使用APN ID的报文发起流量攻击,这对网络稳定运行将带来风险。
对于流派三,以BSID开放网络连接将带来和APN类似的安全风险,即网络内部信息被泄露引发的攻击及滥用问题。因此这种方式仅限于在内网使用。
总的来说,流派一和流派二均是采用以应用为中心的思路,网络需要被动适配应用变化,流派三采用网络能力开放的思路,均存在网络安全问题。
基于此,本公开实施例中,用户边界设备获取第一ARN标识;所述第一ARN标识表征应用对网络能力的调用关系和/或网络对应用开放的能力;基于所述第一ARN标识对第一IP报文进行标记,生成第二IP报文;发出所述第二IP报文。
参见图2,图2是本公开实施例信息处理方法的实现流程示意图,应用于用户边界设备,所述用户边界设备可以是一个客户端路由器、SD-WAN CPE、云网关或者是一个应用程序,如图2所示,所述方法包括步骤201至步骤203:
步骤201:获取第一ARN标识;所述第一ARN标识表征应用对网络能力的调用关系和/或网络对应用开放的能力。
这里,所述网络能力可以指网络资源,具体可以包括路径或切片,所述路径可以理解为隧道。
这里,所述路径或切片的服务类型包括但不限于以下之一:
低时延;
大带宽;
低丢包。
这里,所述应用对网络能力的调用关系可以包括但不限于以下之一:
应用对低时延的网络能力的调用;
应用对大带宽的网络能力的调用;
应用对低丢包的网络能力的调用。
这里,所述应用对低时延的网络能力的调用,也可以描述为应用对低时延的路径或切片服务的调用。
这里,应用对大带宽的网络能力的调用,也可以描述为应用对大带宽的路径或切片服务的调用。
这里,应用对低丢包的网络能力的调用,也可以描述为应用对低丢包的路径或切片服务的调用。
这里,所述网络对应用开放的能力可以是指网络资源,具体可以包括路径或切片,所述路径可以理解为隧道。
步骤202:基于所述第一ARN标识对第一IP报文进行标记,生成第二IP报文。
作为示例,所述第一IP报文可以是指IPv6报文。
在一些实施例中,所述基于所述第一ARN标识对第一IP报文进行标记,包括:
将所述第一ARN标识和第一信息分别写入所述第一IP报文的头部中的流标签域和流量类型域;
其中,所述第一信息用于指示是否将流标签域中的原始内容转义为所述第一ARN标识。
作为示例,所述第一信息也可以描述为转义字符。
作为示例,所述第一信息可以位于所述流量类型域(traffic class)的最高位。
也就是说,复用流标签(Flow Label)域,并通过流量类型域(tc,traffic class)的最高位(转义字符)指明是否转义,如果该比特为1,则将流标签域中的原始内容转义为所述第一ARN ID;否则,不进行转义。
在一些实施例中,所述基于所述第一ARN标识对第一IP报文进行标记,包括:
将所述第一ARN标识写入所述第一IP报文的扩展头中;
或者,
将所述第一ARN标识写入所述第一IP报文的头部中的源地址域。
作为示例,所述扩展头可以是指DOH、HBH、SRH头。
这里,在所述第一IP报文中引入ARN ID字段,将应用和网络通过所述第一ARN ID粘合,所述第一ARN ID不但表达了应用和网络之间的调用关系,同时也表达应用对网络路径或切片的需求,例如时延、丢包、抖动、带宽等路径约束。
在一些实施例中,所述获取第一ARN标识,包括:
获取控制器发送的第一ARN标识;
其中,所述第一ARN标识是所述控制器基于用户信息、应用信息和网络服务信息为所述用户边界设备分配的。
这里,所述网络服务信息可以包括服务质量(QoS,Quality of Service)、网络接口等。
举例来说,假设网络中规划了低时延的切片或路径(隧道)服务,在用户订阅一个低时延的连接服务时,网络如何完成该业务流程并进行转发。首先,业务系统根据用户订阅的业务类型调用控制器接口,控制器在收到用户的网络服务订阅需求后,为所述用户边界设备分配所述第一ARN标识。
具体地,控制器可以基于用户信息、应用信息和网络服务信息,为所述用户边界设备分配所述第一ARN标识。
这里,第一ARN ID可以是一个任意整数,满足<用户、应用、网络服务>和ARN ID一比一对应就可以。具体地,可以利用随机函数生成、或按照从小到大、或从大到小生成均可。
这里,控制器为用户边界设备分配第一ARN ID之后,还可以对所述第一ARN标识的生命周期进行管理,具体包括:
对所述第一ARN标识执行以下操作之一:
撤销;
挂失;
补发;
老化;
延期。
这里,所述撤销是指控制器在用户及网络边缘上删除相关ARN ID信息。
这里,所述挂失也是对应撤销相关的ARN ID。
这里,所述补发是指需要重新生成一个ARN ID。
这里,所述老化是指对应APN服务有时间限制,到时间后自动撤销相应的ARN ID。
这里,所述延期是指延长ARN ID的服务时间。
步骤203:发出所述第二IP报文。
作为示例,可以将所述第二IP报文发送至网络边界设备。
作为示例,所述网络边界设备对家庭用户来说是BRAS/BNG,对无线用户来说是对接核心网的路由器,对于政企用户来说就是接入用户专线的PE。
作为示例,所述网络边界设备接收到所述第二IP报文后,解析所述第二IP报文,得到所述第一IP报文中携带的所述第一ARN标识;对所述第一ARN标识的合法性进行验证。
具体地,对所述第一ARN标识的合法性进行验证,包括以下两种情况:
第一种情况,如果验证所述第一ARN标识合法,则基于所述第一ARN标识,将所述第二IP报文映射到对应的路径或切片。
第二种情况,如果验证所述第一ARN标识不合法的情况下,执行第一操作。
其中,所述第一操作包括以下之一:
忽略所述第二IP报文携带的所述第一ARN标识或丢弃所述第二IP报文;
将所述第一ARN标识的值进行重置;
将所述第二IP报文映射到不携带ARN标识的报文对应的默认路径或切片。
实际应用时,为了网络边界设备对所述第一ARN标识的合法性进行验证,所述用户边界设备可以将第一用户信息携带于所述第二IP报文中,以便于网络边界设备对所述第一ARN标识进行验证。
基于此,在一些实施例中,所述发出所述第二IP报文,包括:
将第一用户信息携带于所述第二IP报文中;
发出所述第二IP报文。
本公开实施例中,具备以下优点:
(1)用户边界设备获取第一ARN标识;所述第一ARN标识表征应用对网络能力的调用关系和/或网络对应用开放的能力;基于所述第一ARN标识对第一IP报文进行标记,生成第二IP报文;发出所述第二IP报文。
本公开实施例中,由于所述第一ARN标识表征应用对网络能力的调用关系和/或网络对应用开放的能力,如此,用户或应用并不直接调用网络能力,而是通过所述第一ARN标识调用网络能力,这样网络就不会看到用户或应用的相关信息,同样地,网络并直接开放能力给用户,而是通过所述第一ARN标识开放能力,这样用户就不会看到网络的服务信息,从而在提供应用协同网络能力的同时提高安全性。
(2)与相关技术中通过APN、BSID、ACL等实现应用协同网络能力的方式相比,本公开实施例中,采用ARN标识,差异就是用户/应用并不能直接调用网络路径,得通过中间层ARN调用网络服务,而网络也不能看到用户应用信息,看到的只是中间层ARN。相比之下,APN直接携带应用和用户信息,网络直接就看到了这些信息,BSID直接把网络能力开放给用户,用户直接看到了网络服务信息。
隐私性方面,ARN ID不直接使用网络连接标识,例如BSID或SID,而是使用独立于BSID的ARN ID,且报文中的ARN ID针对不同用户取值范围随机,可由控制器将一个用户网络需求合同映射为不同设备的不同ARN ID值,设置为设备有效而非全局有效,针对不同设备可以是不同ARN ID值,因此既不携带网络隐私信息也不携带用户隐私信息。
可维护性方面,通过ARN ID表达网络能力,不受应用变化而变化,因此不存在应用快速迭代带来的配置频繁变化的问题,便于通过规划的方式将网络能力对外开放。同时由于ARN ID和用户实际付费的合同一一对应,信息配置容易嵌入到业务流程中,不存在将合同转化为ACL五元组或者APN ID的问题。
扩展性方面,如果仅对差异化的用户需求配置(ARN ID,用户)的2元组,并且该2元组可以通过查表来实现,因此本方案不存在扩展性问题。
安全性方面,ARN ID是处于应用和网络的中间,像合同一样存在生命周期,有创建、销毁、超期、更新、校验等操作能力。一旦ARN ID信息被发现泄露则可以在不影响其他用户业务的情况下快速挂失,并申请新的ARN ID信息。同时进入SR网络的报文可不携带BSID/SID也可以根据ARN ID正确映射到对应SR Policy路径,即便携带BSID/SID时,则可以根据ARN ID来校验对于网络的BSID/SID调用是否合法。这样解决了安全问题。
最后,网络ARN ID的作用域可分为两类:一类是全局ARN ID,在个其生命周期相同,但是不同站点同一ARN ID在不同设备上可以不同;另一类是本地化ARN ID,针对单个用户本地化需求,不同ARN ID生命周期互相独立。客户有局部ARN ID需在报文中携带。因为ARN ID值部要求全局采用相同的值,因此将协同需求降到最低。
(3)采用以网络为中心的思路,提出应用响应网络(Application Responsive Networking)技术,解决系列化安全问题,消除快速变化的应用对网络稳定配置的影响,通过应用主动调用网络能力,具备大规模部署的能力。能够解决相关技术中应用变化带来网络ACL、DPI、APN等配置频繁变化导致网络稳定性难以收敛的问题,以及解决相关技术中应用特征高度离散,难以被聚合因此做ACL、APN配置需要针对每业务一条一条配置,资源消耗量大且维护困难的问题,以及解决相关技术中APN、BSID必须携带隐私信息的问题,以及解决相关技术中APN、BSID等信息泄露后引发的APN ID、BSID被冒用、被攻击等安全问题。

将所述第二IP报文映射到不携带ARN标识的报文对应的默认路径或切片。
作为示例,所述将所述第一ARN标识的值进行重置,可以是将所述第一ARN ID按配置被重置为0。
这里,如果选择忽略所述第一ARN ID,通过默认隧道/切片进行转发。如果报文中不携带ARN ID的报文也应通过默认隧道/切片进行转发。这样在网络升级过程中,不需要用户侧设备和网络边界设备同步支持该特性。

若从所述预设数据表中查找到所述第一用户信息和所述第一ARN标识的对应关系,则确定所述第一ARN标识合法。
作为示例,若从所述预设数据表中未查找到所述第一用户信息和所述第一ARN标识的对应关系,则确定所述第一ARN标识不合法。
作为示例,可以通过所述第二IP报文的源地址域获得所述第一用户信息。
举例来说,用户信息和ARN标识的预设对应关系可以包括:用户信息为Ua,对应的ARN标识为数值1,用户信息为Ub,对应的ARN标识为数值2,用户信息为Uc,对应的ARN标识为数值3。如此,假设所述第一用户信息为Ub,所述第一ARN标识为数值2,表明从所述预设数据表中查找到所述第一用户信息和所述第一ARN标识的对应关系,则确定所述第一ARN标识合法。
在一些实施例中,所述基于所述第一ARN标识,将所述第二IP报文映射到对应的路径或切片,包括:
如果所述第一ARN标识合法,根据路径或切片和ARN标识的预设对应关系,确定与所述第一ARN标识对应的第一路径或第一切片;将所述第二IP报文映射到所述第一路径或所述第一切片;

多协议标签交换(MPLS);
互联网第三层协议(IPinIP);
虚拟扩展局域网(VxLAN);

作为示例,所述网络边界设备可以从控制器获取SRv6、多协议标签交换MPLS、互联网第三层协议IPinIP、虚拟扩展局域网VxLAN、通用路由封装协议GRE、通用网络虚拟化封装GENEVE等隧道和ARN标识的预设对应关系。
举例来说,以SRv6为例,假设有SRv6隧道1、SRv6隧道2、SRv6隧道3,SRv6隧道1为隧道颜色标识a(大带宽的路径或切片),对应的ARN标识为数值1,SRv6隧道2为隧道颜色标识b(低时延的路径或切片),对应的ARN标识为数值2,SRv6隧道3为隧道颜色标识c(低丢包的路径或切片),对应的ARN标识为数值3。如此,假设所述第一ARN标识为数值2,则可以确定对应的第一路径或第一切片为SRv6隧道2,如此,将所述第二IP报文映射到与隧道颜色标识b对应的低时延的路径或切片。

参见图5,图5是本公开实施例信息处理方法应用的系统架构示意图,如图5所示,所述系统包括:
控制器,用于为用户边界设备分配第一ARN标识;所述第一ARN标识表征应用对网络能力的调用关系和/或网络对应用开放的能力。
用户边界设备(CPE1),用于基于所述第一ARN标识对第一IP报文进行标记,生成第二IP报文;发出所述第二IP报文至网络边界设备。
网络边界设备(PE),用于解析所述第二IP报文,得到所述第一ARN标识和第一用户信息(如用户ID);利用所述第一用户信息,对所述第一ARN标识的合法性进行验证,如果所述第一ARN标识合法,则基于所述第一ARN标识,将所述第二IP报文映射到对应的路径或切片。
这里,所述用户边界设备可以是一个客户端路由器、SD-WAN CPE、云网关或者是一个应用程序。
这里,所述网络边界设备对家庭用户来说是BRAS/BNG,对无线用户来说是对接核心网的路由器,对于政企用户来说就是接入用户专线的PE。
参见图6,图6是本公开实施例信息处理方法的具体实现流程示意图,如图6所示,所述方法包括步骤601至步骤606:
步骤601:控制器为用户边界设备分配第一ARN标识;所述第一ARN标识表征应用对网络能力的调用关系和/或网络对应用开放的能力。
这里,所述网络能力可以指网络资源,具体可以包括路径或切片,所述路径可以理解为隧道。
这里,所述路径或切片的服务类型包括但不限于以下之一:
低时延;
大带宽;
低丢包。
这里,所述应用对网络能力的调用关系可以包括但不限于以下之一:
应用对低时延的网络能力的调用;
应用对大带宽的网络能力的调用;
应用对低丢包的网络能力的调用。
这里,所述应用对低时延的网络能力的调用,也可以描述为应用对低时延的路径或切片服务的调用。
这里,应用对大带宽的网络能力的调用,也可以描述为应用对大带宽的路径或切片服务的调用。
这里,应用对低丢包的网络能力的调用,也可以描述为应用对低丢包的路径或切片服务的调用。
这里,所述网络对应用开放的能力可以是指网络资源,具体可以包括路径或切片,所述路径可以理解为隧道。
举例来说,假设网络中规划了低时延的切片或路径(隧道)服务,在用户订阅一个低时延的连接服务时,网络如何完成该业务流程并进行转发。首先,业务系统根据用户订阅的业务类型调用控制器接口,控制器在收到用户的网络服务订阅需求后,为所述用户边界设备分配所述第一ARN标识。
具体地,控制器可以基于用户信息、应用信息和网络服务信息,为所述用户边界设备分配所述第一ARN标识。
这里,第一ARN ID可以是一个任意整数,满足<用户、应用、网络服务>和ARN ID一一对应就可以。具体地,所述第一ARN标识可以利用随机函数生成、或按照从小到大、或从大到小生成均可。
图7是本公开实施例控制器为用户边界设备分配第一ARN ID的示意图,如图7所示,假设用户信息为Ua、应用信息为视频应用、所述网络服务信息为低时延的路径或切片,则从未分配ARN ID数据库中进行随机选取一个ARN ID,作为第一ARN ID分配给对应的用户边界设备。同样地,假设用户信息为Ua、应用信息为视频应用、所述网络服务信息为低时延和大带宽的路径或切片,则从未分配ARN ID数据库中进行随机选取两个ARN ID,作为第一ARN ID分配给对应的用户边界设备。
这里,所述用户边界设备用于调用网络能力。
其中,所述用户边界设备可以是一个客户端路由器、SD-WAN CPE、云网关或者是一个应用程序。
图8是本公开实施例ARN ID的生命周期示意图,如图8所示,ARN ID有三个状态:未分配、活跃期、静默期,其中,初始阶段ARN ID都在未分配状态下;一旦分配就进入活跃期,在活跃期,ARN ID服务合约超期、用户提前终结或挂失都将导致ARN ID进入静默期状态;静默期的ARN ID已处于停服状态,目的是为避免冲突或安全风险因此在一段时间内不对外分配,等待一段时间后(一般为半年或一年以上)重新回收到未分配ARN ID数据库中。
这里,控制器为用户边界设备分配第一ARN ID之后,还可以对所述第一ARN标识的生命周期进行管理,具体包括:
对所述第一ARN标识执行以下操作之一:
撤销;
挂失;
补发;
老化;
延期。
这里,所述撤销是指控制器在用户及网络边缘上删除相关ARN ID信息。
这里,所述挂失也是对应撤销相关的ARN ID。
这里,所述补发是指需要重新生成一个ARN ID。
这里,所述老化是指对应APN服务有时间限制,到时间后自动撤销相应的ARN ID。
这里,所述延期是指延长ARN ID的服务时间。
步骤602:用户边界设备基于所述第一ARN标识对第一IP报文进行标记,生成第二IP报文。
这里,所述第一IP报文可以是指IPv6报文。
这里,所述第一ARN ID的长度最少为10bit以上。
下列方式以第一ARN ID为20bit描述几种在报文中携带的帧格式,在IPv6报文中,可以按照以下几种方式放置ARN标识(ID)信息:
第一种携带方式是IPv6头转义方式。
参见图9,图9是本公开实施例对第一IP报文进行标记的示意图,如图9所示,假设第一IP报文为IPv6报文,ARN ID为20bit,将ARN ID和第一信息(转义字符)分别写入IPv6报文的头部中的流标签域(Flow Label)和流量类型域(traffic class);其中,所述第一信息用于指示是否将流标签域中的原始内容转义为ARN ID。
也就是说,复用流标签(Flow Label)的20bit,并通过流量类型域(tc,traffic class)的最高位(转义字符)指明是否转义,如果该比特为1,则将流标签域中的原始内容转义为ARN ID;否则,不进行转义。
第二种方式是通过IPv6扩展头携带。
参见图10,图10是本公开实施例对第一IP报文进行标记的示意图,如图10所示,假设第一IP报文为IPv6报文,ARN ID为20bit,将所述ARN ID写入IPv6报文的扩展头即DOH、HBH中,type指示该4个字节(0到31比特)是ARN ID,flag为预留未定义。
第三种方式是通过IPv6扩展头携带。
参见图11,图11是本公开实施例对第一IP报文进行标记的示意图,如图11所示,假设第一IP报文为IPv6报文,ARN ID为20bit,将所述ARN ID写入IPv6报文的扩展头SRH头,type指示该4个字节(0到31比特)是ARN ID,flag为预留未定义。
第四种方式是通过IPv6源地址携带。
参见图12,图12是本公开实施例对第一IP报文进行标记的示意图,如图12所示,假设第一IP报文为IPv6报文,ARN ID为20bit,将所述ARN ID写入IPv6报文的源地址域中。
综上,在第一IP报文中主动携带第一ARN ID,具体位置可以是DOH、HBH、SRH、FlowLabel、源地址。具体的,如果复用Flow Label来携带ARN ID时,还需要设置流量类型域(TC)的第7位为1,用于指明当前Flow Label中携带的是ARN ID。当采用DOH、HBH、SRH来携带ARN ID时,需要额外定义type字段,表明该32bit携带的是ARN ID。通过源地址携带ARN ID时,需要通过配置来指明通过某链路或某IP收到的报文均通过源地址携带ARN ID。
步骤603:用户边界设备将所述第二IP报文发送给网络边界设备。
这里,所述网络边界设备对家庭用户来说是BRAS/BNG,对无线用户来说是对接核心网的路由器,对于政企用户来说就是接入用户专线的PE。
步骤604:网络边界设备解析所述第二IP报文,得到所述第一ARN标识;对所述第一ARN标识的合法性进行验证。
具体地,根据预设数据表,对所述第一ARN标识的合法性进行验证;所述预设数据表中存储有用户信息和ARN标识的预设对应关系。其中,所述用户信息可以包括用户对应的用户标识或源地址信息或链路信息。
也就是说,网络边界设备的接口上保存ARN ID校验表即所述预设数据表,数据表中每一项包含有用户信息和ARN标识的对应关系,其中,用户信息可以由源IP地址等表示。
这里,网络边界设备可以从控制器获取所述预设数据表。
这里,网络边界设备在接收到包含第一ARN ID的第二IP报文时,可以根据所述第二IP报文中的源IP地址获得第一用户信息,并根据所述第二IP报文获得所述第一ARN ID,然后再查找所述预设数据表中是否包含所述第一用户信息和所述第一ARN标识的对应关系,以对所述第一ARN标识进行合法性校验。
表1是用户信息和ARN标识的对应关系的示意,如表1所示,用户信息为Ua,对应的ARN标识为数值1,用户信息为Ub,对应的ARN标识为数值2,用户信息为Uc,对应的ARN标识为数值3。
表1
这里,所述根据预设数据表,对所述第一ARN标识的合法性进行验证,包括:
解析所述第二IP报文,得到第一用户信息;
从所述预设数据表中查找所述第一用户信息和所述第一ARN标识的对应关系;
若从所述预设数据表中查找到所述第一用户信息和所述第一ARN标识的对应关系,则确定所述第一ARN标识合法;
若从所述预设数据表中未查找到所述第一用户信息和所述第一ARN标识的对应关系,则确定所述第一ARN标识不合法。
这里,可以通过入接口链路或者所述第二IP报文中的源IP地址获取所述第一用户信息。
步骤605:在验证所述ARN标识合法的情况下,基于所述第一ARN标识,将所述第二IP报文映射到对应的路径或切片。
具体地,所述基于所述第一ARN标识,将所述第二IP报文映射到对应的路径或切片,包括:
根据路径或切片和ARN标识的预设对应关系,确定与所述第一ARN标识对应的第一路径或第一切片;将所述第二IP报文映射到所述第一路径或所述第一切片;
其中,所述路径或切片,包括以下之一:
基于策略的IPv6分段路由(SRv6);
多协议标签交换(MPLS);
互联网第三层协议(IPinIP);
虚拟扩展局域网(VxLAN);
通用路由封装协议(GRE);
通用网络虚拟化封装(GENEVE)。
这里,网络边界设备可以从控制器获取路径或切片和ARN标识的预设对应关系。
表2是SRv6隧道和ARN标识的对应关系的示意,如表2所示,以SRv6为例,包括SRv6隧道1、SRv6隧道2、SRv6隧道3,SRv6隧道1为隧道颜色标识a(大带宽的路径或切片),对应的ARN标识为数值1,SRv6隧道2为隧道颜色标识b(低时延的路径或切片),对应的ARN标识为数值2,SRv6隧道3为隧道颜色标识c(低丢包的路径或切片),对应的ARN标识为数值3。
表2
这里,假设所述第一ARN标识为数值2,则根据表2可以确定对应的第一路径或第一切片为SRv6隧道2即隧道颜色标识b(低时延的路径或切片),如此,将所述第二IP报文映射到SRv6隧道2。
步骤606:在验证所述ARN标识不合法的情况下,执行第一操作。
这里,所述第一操作包括以下之一:
忽略所述第二IP报文携带的所述第一ARN标识或丢弃所述第二IP报文;
将所述第一ARN标识的值进行重置;
将所述第二IP报文映射到其他路径或切片。
也就是说,如果所述第二IP报文携带的第一ARN ID不为无效的0值且合法性校验失败时,所述第二IP报文可以根据配置进行如下处理:
按配置忽略所述第二IP报文中的所述第一ARN ID或丢弃所述第二IP报文;或者,
将所述第一ARN ID按配置被重置为0;或者,
如果选择忽略所述第一ARN ID,则所述第二IP报文按不包含ARN ID的切片、隧道进行转发。
也就是说,如果选择忽略所述第一ARN ID,通过默认隧道/切片进行转发。如果报文中不携带ARN ID的报文也应通过默认隧道/切片进行转发。这样在网络升级过程中,不需要用户侧设备和网络边界设备同步支持该特性。
这里,协同应用需求和网络能力方面,网络ARN ID主要在网络边界业务接入点(例如PE、BRAS/BNG)上应用。
举例来说,假设网络中规划了低时延的切片或隧道服务,在用户订阅一个低时延的连接服务时,首先,业务系统根据用户订阅的业务类型调用控制器接口,控制器在收到用户的网络服务订阅需求后,会根据连接的两端位置找到对应的网络边界设备(PE/BRAS/BNG),并在这对PE/BRAS/BNG之间根据用户低时延需求新建或复用对应低时延的颜色隧道标识(color)的SRv6、多协议标签交换(MPLS)、互联网第三层协议(IPinIP)、虚拟扩展局域网(VxLAN)、通用路由封装协议(GRE)、通用网络虚拟化封装(GENEVE)等,得到相应的隧道/切片,同时控制器会针对用户、应用和网络服务(对应color)生成ARN ID,并查找用户对应的源地址信息或链路信息用于标识用户,然后将用户(源地址或链路信息)和ARN ID下发到网络边界业务接入点PE/BRAS/BNG上,并和网络资源切片/隧道相关联,这样完成了网络侧PE/BRAS/BNG的配置。
在用户侧网络,控制器根据用户找到对应的用户边界设备(CPE/网关设备),然后下发ARN ID信息。这样用户在后续应用中可以根据应用类型来标记ARN ID,发送报文到网络边界设备(PE/BRAS/BNG)时,可以进行合法性校验,实现相应网络能力的调用。用户还可以通过ACL、指定链路等方式为应用标记ARN ID,在用户侧报文中打上ARN ID。
可以看出,在为用户提供差异化网络服务时,网络服务上可通过ARN ID而不是BSID/SID来为用户提供差异化的连接(低时延、大带宽隧道/切片)。在用户侧边界设备上,多个ARN ID可以映射到一个SR Policy。ARN ID提供为每用户分配不同值的能力,不同于多个用户共享一个BSID导致的安全性问题。和APN6不同,ARN ID的值是一个不显式携带应用、用户信息的数值,可以为随机数或顺序分配的值,因此不存在APN6暴露用户隐私的问题。在网络侧边界设备上,和APN6以及BSID不同,多个可映射为相同网络能力的ARN ID可以被聚合为一个ARN ID。
这里,所述第一ARN ID可以和用户信息一起进行流量计费。用户信息在BRAS/BNG场景下可以根据链路,即PPPoE连接来标识,在PE场景下可根据源IP地址、或专线链路来标识。
这里,所述第一ARN ID的作用范围可以是全局也可以是本地有效,本地有效指在设备的不同ARN ID保持唯一即可;全局指在某一范围的设备内特定用户的一个或多个ARN ID可映射到网络中一个隧道/切片。
本示例中,具备以下优点:
(1)由于ARN ID不显式携带用户的应用信息,且每个用户ARN ID不同,这样解决了用户隐私性问题,也解决了不同用户共享BSID带来的网络安全性问题。
(2)用户在报文中主动添加ARN ID,ARN ID实际上可以等价于选路策略Color(直接对应于SR Policy的Color),用户报文携带ARN ID信息进入网络边界业务接入点设备(后面简称为PE)后,PE可以根据源IP得到用户信息,并对ARN ID进行合法性校验后,然后将ARN ID映射到特定的网络隧道/切片。
