Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

For example, "A and / or B" may mean: A exists alone, A and B exist at the same time, and B exists alone.

[0021] The descriptions of "first", "second", etc. involved in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the technical features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0022] Figure 1 One of the method flow charts of an embodiment of the network resource pool session synchronization method provided by the present invention is as follows Figure 1 As shown, the network resource pool session synchronization method includes: S101, encapsulating the acquired TCP message to obtain an encapsulated message; the TCP message includes a handshake message or a wave message; the encapsulated message includes a multicast message or a broadcast message; S102. Send the encapsulated message to a second device in a network resource pool through a preset synchronization line; the encapsulated message is used for the second device to perform session synchronization.

[0023] The execution subject of the network resource pool session synchronization method provided by the present invention can be a first device, and the network resource pool includes multiple BRAS / vBRAS devices, wherein the first device can be any BRAS / vBRAS device in the network resource pool, and the second device can be a BRAS / vBRAS device in the network resource pool except the first device.

[0024] It should be noted that TCP messages include handshake messages or wave messages, and TCP messages can be used to establish or terminate TCP connections. Handshake messages can be SYN, SYN-ACK, or ACK, and wave messages can be FIN, FIN-ACK, etc.

[0025] In S101, the acquired TCP message is encapsulated to obtain an encapsulated message; the TCP message includes a handshake message or a wave message; the encapsulated message includes a multicast message or a broadcast message.

[0026] The first device may capture a TCP message from a network layer or an application layer, and after obtaining the TCP message, immediately encapsulate the TCP message and convert it into a format suitable for transmission in a specific network environment, such as a multicast message or a broadcast message.

[0027] In S102, the encapsulated message is sent to a second device in a network resource pool through a preset synchronization line; the encapsulated message is used for the second device to perform session synchronization.

[0028] The preset synchronization line is a high-bandwidth, low-latency communication link that can ensure the reliability and stability of messages during transmission, reduce the possibility of data loss or errors, and is specifically used for session synchronization information transmission between BRAS devices in the network resource pool.

[0029] The first device sends the encapsulated message to all the second devices in the network resource pool through a preset synchronization line, so that the second devices can receive and parse the encapsulated message, thereby achieving synchronization of the session state.

[0030] Exemplarily, when any BRAS device in the resource pool receives a TCP handshake message, the handshake message is encapsulated as a multicast message or a broadcast message, and forwarded to all other BRAS devices in the resource pool through a synchronous dedicated line to ensure that all devices can establish a TCP session based on the TCP handshake message.

[0031] When any BRAS device in the resource pool receives a TCP wave message, it also encapsulates the wave message into a multicast message or a broadcast message and forwards it through a synchronous dedicated line to notify other devices in the resource pool to release the corresponding TCP session and achieve synchronous termination of the session.

[0032] Compared with the prior art, the network resource pool session synchronization method provided in the embodiment of the present invention immediately encapsulates the TCP message into a multicast message or a broadcast message when the first device obtains the TCP message, and forwards it to all other second devices in the network resource pool through a preset synchronization line, so that the second device can synchronously update its own TCP session table according to the received multicast message or broadcast message, so as to ensure that the devices in the network resource pool can establish and maintain TCP sessions in real time according to the handshake message or the wave message, thereby performing session synchronization and ensuring the consistency of the session state. By forwarding the handshake message or the wave message in real time, the session information between the BRAS devices in the resource pool is quickly and accurately synchronized, which effectively improves the session management capability of the network resource pool and the overall network performance.

[0033] In some embodiments of the present invention, encapsulating the acquired TCP message to obtain an encapsulated message includes: A synchronization mark and a timestamp are added to the TCP message to obtain the encapsulated message.

[0034] The process of encapsulating the message may include: adding a synchronization identifier and a timestamp on the basis of retaining the key information of the TCP handshake / wave message to ensure the validity and freshness of the message.

[0035] In some embodiments of the present invention, it further comprises: When receiving traffic of an unsynchronized session, generating a hash value according to a target feature of the traffic; Sending a query message to the second device in a multicast manner; the query message includes the hash value; receiving a response message sent by the second device; the response message is sent by the second device when determining that a session matching the hash value exists in the session hash table; The session synchronization is performed based on the response message.

[0036] When the first device fails to synchronize to certain sessions due to a newly added device or a device failure, and the unsynchronized sessions generate traffic, the first device may generate a unique hash value according to target features of the traffic.

[0037] The first device initiates a query to all second devices in the resource pool in a multicast manner, requesting to confirm whether there is a session corresponding to the hash value, that is, sending a query message to all second devices, the query message including the generated hash value.

[0038] After receiving the inquiry message, the second device searches its own session hash table to determine whether there is a session matching the hash value.

[0039] The session hash table is used to store session information of all devices in the resource pool so as to query and respond when receiving inquiries.

[0040] If there is a session matching the hash value, a response message is sent to the first device, where the response message includes the duration of the session and other relevant information.

[0041] After receiving the response message, the first device establishes and maintains the corresponding TCP session according to the information contained in the response message, thereby achieving rapid synchronous recovery of the session.

[0042] Exemplarily, after receiving the response message, the first device may establish a new session entry according to the information contained in the response message, and simulate the TCP handshake process to ensure that subsequent data packets can be processed correctly.

[0043] If multiple second devices all send response messages, the first device may decide how to establish and maintain the new session according to a preset policy (for example, selecting the session with the longest duration).

[0044] The network resource pool session synchronization method provided in the embodiment of the present invention realizes fast session synchronization between devices by forwarding TCP handshake / wave messages in real time and handling the situation of unsynchronized sessions, ensures session continuity when users seamlessly switch devices in the network resource pool, and improves the efficiency and stability of session synchronization.

[0045] In some embodiments of the present invention, the target features include: Protocol type, source IP address, destination IP address, source port, and destination port.

[0046] A preset hash algorithm can be used to generate a unique hash value based on the target characteristics of the traffic. The target characteristics include protocol type, source IP address, destination IP address, source port and destination port. The hash value can be used to uniquely identify this specific session, thereby ensuring the accuracy of the query.

[0047] Figure 2 A second method flow chart of an embodiment of the network resource pool session synchronization method provided by the present invention is as follows: Figure 2 As shown, the network resource pool session synchronization method includes: S201, receiving an encapsulated message through a preset synchronization line; the encapsulated message is obtained by the first device encapsulating the acquired TCP message; the TCP message includes a handshake message or a wave message; the encapsulated message includes a multicast message or a broadcast message; S202: Perform session synchronization based on the encapsulated message.

[0048] The execution subject of the network resource pool session synchronization method provided by the present invention can be a second device. The network resource pool includes multiple BRAS / vBRAS devices, wherein the first device can be any BRAS / vBRAS device in the network resource pool, and the second device can be a BRAS / vBRAS device in the network resource pool except the first device.

[0049] The first device may capture a TCP message from a network layer or an application layer, and after obtaining the TCP message, immediately encapsulate the TCP message and convert it into a format suitable for transmission in a specific network environment, such as a multicast message or a broadcast message.

[0050] The preset synchronization line is a high-bandwidth, low-latency communication link that can ensure the reliability and stability of messages during transmission, reduce the possibility of data loss or errors, and is specifically used for session synchronization information transmission between BRAS devices in the network resource pool.

[0051] The first device sends the encapsulated message to all the second devices in the network resource pool through a preset synchronization line, so that the second devices can receive and parse the encapsulated message, thereby achieving synchronization of the session state.

[0052] The network resource pool session synchronization method provided in the embodiment of the present invention immediately encapsulates the TCP message into a multicast message or a broadcast message when the first device obtains the TCP message, and forwards it to all other second devices in the network resource pool through a preset synchronization line, so that the second device can synchronously update its own TCP session table according to the received multicast message or broadcast message, so as to ensure that the devices in the network resource pool can establish and maintain TCP sessions according to the handshake message or the wave message in real time, thereby performing session synchronization and ensuring the consistency of the session state. By forwarding the handshake message or the wave message in real time, the session information between the BRAS devices in the resource pool is quickly and accurately synchronized, which effectively improves the session management capability of the network resource pool and the overall network performance.

[0053] In some embodiments of the present invention, it further includes: Receiving a query message sent by the first device; the query message includes a hash value; the hash value is generated based on a target feature of traffic of an unsynchronized session; When it is determined that there is a session matching the hash value in the session hash table, a response message is sent to the first device; the response message is used by the first device to perform session synchronization.

[0054] When the first device fails to synchronize to certain sessions due to a newly added device or a device failure, and the unsynchronized sessions generate traffic, the first device may generate a unique hash value according to target features of the traffic.

[0055] The first device initiates a query to all second devices in the resource pool in a multicast manner, requesting to confirm whether there is a session corresponding to the hash value, that is, sending a query message to all second devices, the query message including the generated hash value.

[0056] After receiving the inquiry message, the second device searches its own session hash table to determine whether there is a session matching the hash value.

[0057] The session hash table is used to store session information of all devices in the resource pool so as to query and respond when receiving inquiries.

[0058] If there is a session matching the hash value, a response message is sent to the first device, where the response message includes the duration of the session and other relevant information.

[0059] After receiving the response message, the first device establishes and maintains the corresponding TCP session according to the information contained in the response message, thereby achieving rapid synchronous recovery of the session.

[0060] The network resource pool session synchronization method provided in the embodiment of the present invention realizes fast session synchronization between devices by forwarding TCP handshake / wave messages in real time and handling the situation of unsynchronized sessions, ensures session continuity when users seamlessly switch devices in the network resource pool, and improves the efficiency and stability of session synchronization.

[0061] The network resource pool session synchronization method provided by the present invention realizes real-time and efficient synchronization of TCP session information between BRAS devices in the resource pool by optimizing the synchronization mechanism, thereby ensuring the consistency of the session status of all devices. The synchronization method includes real-time session synchronization and session query and recovery.

[0062] (1) Real-time session synchronization: When any BRAS device in the resource pool receives a TCP handshake (SYN) or wave (FIN / RST) message, it immediately encapsulates the message into a multicast or broadcast message and forwards it to all other devices in the resource pool through a preset dedicated synchronization line. The receiving device synchronously updates its own TCP session table based on the content of the received message, thereby ensuring that all BRAS devices can establish and maintain TCP sessions in real time based on TCP handshake / wave messages, achieving consistency in session status.

[0063] (2) Session query and recovery: If some devices fail to synchronize to certain sessions due to the addition of new devices or device failure, when these unsynchronized sessions generate traffic, the device receiving the traffic will use the traffic protocol type, source IP address, destination IP address, source port, and destination port information to generate a unique hash value. Subsequently, the device initiates a query to all devices in the resource pool via multicast, requesting confirmation of whether a session corresponding to the hash value exists. After receiving the query, other devices query their own session table and return response information on whether the session exists, including the current duration of the session. If any positive response is received, the device that is not synchronized to the session establishes and maintains the corresponding session based on the response information.

[0064] The present invention also provides a network resource pool session synchronization system, comprising: The message encapsulation and forwarding module is responsible for encapsulating the received TCP handshake / wave message into a multicast or broadcast message and forwarding it to other devices in the resource pool through a synchronous dedicated line.

[0065] The session table management module maintains the TCP session table of the device and updates the session information according to the received synchronization message or query response.

[0066] The query initiation and response processing module generates a hash value and initiates a query when it detects traffic from an unsynchronized session. It receives and processes query responses from other devices and establishes or updates sessions based on the response information.

[0067] Figure 3 A method flow chart of an embodiment of the network resource pool session synchronization method provided by the present invention is as follows: Figure 3 As shown, the network resource pool session synchronization method includes: S301, message reception and encapsulation.

[0068] When the network interface of any BRAS / vBRAS device in the resource pool, i.e., the first device (hereinafter referred to as the local device), captures a TCP handshake (SYN, SYN-ACK, ACK message sequence) or a wave message (FIN, FIN-ACK, etc.), the message receiving module of the device will immediately respond and read these messages.

[0069] The read TCP handshake or wave message is passed to the message encapsulation and forwarding module. This module first verifies the integrity and validity of the message to ensure that the message has not been tampered with or damaged.

[0070] After verification, the message encapsulation and forwarding module will encapsulate the original TCP handshake or wave message into a new multicast or broadcast message. The encapsulation process may include adding additional header information to identify the message type, source device, timestamp, etc.

[0071] After encapsulation is complete, the module sends the encapsulated message to all other devices in the resource pool through a dedicated synchronization line (which may be a physically isolated VLAN or a dedicated network interface).

[0072] S302: Message forwarding and session synchronization.

[0073] When other devices in the resource pool, namely, second devices (hereinafter referred to as remote devices), receive the encapsulated multicast or broadcast messages, their message receiving modules decapsulate the messages and restore the original TCP handshake or wave messages.

[0074] The session management module of the remote device will establish or update the local TCP session table based on these restored messages. In this way, all devices will maintain a consistent TCP session state.

[0075] S303: Process the situation of unsynchronized session.

[0076] When the local device receives a data packet belonging to an unsynchronized session (i.e., the local device has no record of the session), the session query module is triggered.

[0077] The session query module extracts the protocol type, source IP, destination IP, source port, and destination port of the data packet and uses this information to generate a unique hash value.

[0078] Next, the module constructs a query message containing this hash value and sends it to all other devices in the resource pool via multicast.

[0079] S304: Response information processing and session establishment.

[0080] After receiving the query message, the remote device will search its own session table to see if there is a session that matches the hash value.

[0081] If a matching session exists, the remote device constructs a response message containing the session duration and other relevant information, and then sends it to the local device that initiated the query.

[0082] After the local device receives the response message, the session establishment and maintenance module will establish a new session entry based on this information and simulate the TCP handshake process (if necessary) to ensure that subsequent data packets can be processed correctly.

[0083] If multiple remote devices respond that the session exists, the local device may decide how to establish and maintain the new session based on a certain strategy (such as selecting the session with the longest duration).

[0084] Through the above steps, the present invention ensures that in the network resource pool, the consistency of sessions can be maintained between all BRAS / vBRAS devices, thereby improving the robustness and reliability of the network.

[0085] The network resource pool session synchronization method and device of the present invention realizes fast and accurate synchronization of session information between BRAS devices in the resource pool by forwarding TCP handshake / wave messages in real time and a hash value-based session query and recovery mechanism, thereby effectively improving the session management capability of the network resource pool and the overall network performance.
