Abstract

The invention provides a message processing method. The method comprises: provider edge equipment PE receives a receiving message sent to an integrated controller from client edge equipment CE; the PE finds the receiving message in a cache list of receiving messages according to the message type and business identification in the receiving message; if the PE does not find the receiving message, the PE sends the receiving message to the integrated controller; if the PE finds the receiving message, the PE compares data content of the receiving message with data content of the found receiving message stored in the cache list; and if the data content of the receiving message is different from the data content of the stored receiving message, the PE sends the receiving message to the integrated controller. Processing of refreshing messages by the integrated controller is reduced due to the fact that each network element processes periodical refreshing messages locally, so that CPU utilization rate of the integrated controller is improved, and network size controlled by the integrated controller is increased.

Description

Message processing method, device and system

Technical Field

The present invention relates to the field of communications, and in particular, to a method, device, and system for processing a message.

Background

When a router device Network crosses a transport Network, interaction of protocols such as Multiprotocol Label Switching (MPLS), Border Gateway Protocol (BGP) and the like needs to be performed between the router device and the transport device, so as to complete establishment of an MPLS Label Switching Path (Label switch Path, LSP) or a Level3Virtual Private Network (L3 VPN) service. Because the transmission Network realizes a Software Defined Network (SDN), the transfer device moves the control plane up to the centralized controller, no control function exists on the transfer device, the transfer device reports the protocol message from the router to the centralized controller, the protocol message is processed by the centralized controller, the centralized controller constructs a corresponding response message, and sends the response message to the transfer device, and the transfer device sends the response message to the router. In an actual network, in order to ensure the reliability of a service established by a control protocol, handshake detection of the service protocol needs to be periodically performed between devices, and the content of a handshake detection message (also referred to as a protocol refresh message) is unchanged when the service is not changed.

If the traffic between the router and the transmission device is large, the transmission network centralized controller needs to process a large number of periodical protocol refresh messages with the router, which causes the following problems: (1) a large amount of CPU resources of the centralized controller are occupied by processing a large amount of protocol refreshing messages, so that the rapid control capability of the centralized controller on the network is reduced; (2) a large amount of transmission network devices periodically perform protocol refreshing message interaction with the centralized controller, which occupies a large amount of control channel bandwidth between the centralized controller and the transmission network devices, and reduces the control capability of the centralized controller on the transmission devices.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a method for processing a message according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:

step 101, Provider Edge equipment (PE) receives a receiving message sent by Customer Edge equipment (Customer Edge, CE) to a centralized controller;

102, the PE searches the received message in a cache list of the received message according to the message type and the service identifier in the received message;

specifically, when the received message is a Resource Reservation Protocol (RSVP) PATH message or an RSVP RESV message, the service identifier may be a message receiving interface, a source end node IP of the RSVP LSP, a destination end node IP, a Tunnel ID, and an LSP ID.

Searching the received message in the cache list of the received message comprises two steps:

searching for a received message according to the message type and the service identifier, for example, the message type is PATH, and the PATH message has different cache lists for different services;

and after the received message is found, comparing whether the specific data content is consistent or not.

103, under the condition that the PE does not find the received message, the PE sends the received message to the centralized controller;

104, when the PE finds the received message, the PE compares the data content of the received message with the data content of the received message stored in the cache list;

step 105, if the data content of the received message is different from the stored data content of the received message, the PE sends the received message to the centralized controller.

Optionally, after the PE sends the received message to the centralized controller, the method further includes:

Optionally, the method further comprises:

Optionally, the first message further includes an interface identifier of the received message received by the PE, a receiving cycle duration of the received message, and a receiving cycle number of the received message.

Fig. 2 is an application scenario diagram of message processing according to an embodiment of the present invention, where a Controller is a centralized Controller, PE1 and PE2 are provider edge devices, and CE1 and CE2 are customer edge devices.

In this embodiment, the PE1 receives a received message sent by the CE1, compares the received message with a created receiving buffer list, sends the received message to the centralized controller if the received message is not stored in the receiving buffer list, and does not forward the received message to the centralized controller if the received message is stored in the receiving buffer list.

Specifically, referring to fig. 3, fig. 3 is a schematic diagram of a message processing method according to an embodiment of the present invention, and takes an example that a received message is an RSVP protocol message.

Step 301, PE1 receives an RSVP protocol message sent by CE1, and PE1 encapsulates the received RSVP protocol message as a new Packet payload into a Packet _ IN message of an OpenFlow protocol, and sends the Packet _ IN message to the centralized controller by PE 1;

step 302, after receiving the Packet _ IN message sent by PE1, the centralized Controller analyzes the identifier of PE1 and the Packet payload carried IN the Packet _ IN message from the Packet _ IN message. The centralized controller analyzes the message payload carried IN the Packet _ IN message, checks the message protocol type and determines the message to be RSVP protocol message, and the centralized controller processes the RSVP protocol message and determines the RSVP protocol message to be periodic RSVP PATH or RSVP RESV refreshing message; acquiring, IN the Packet _ IN message of the centralized controller, an interface identifier ID of PE1, a receiving cycle duration of an RSVP protocol message, a receiving cycle number of the RSVP protocol message, and data content of the Packet _ IN message (i.e., an RSVP protocol message);

step 303, the centralized controller sends an add message for creating a cache list of received messages to PE1, where the add message carries RSVP protocol message type, interface identifier of PE1, receiving cycle duration of RSVP protocol message, receiving cycle number of RSVP protocol message, and data content of Packet _ IN message;

at step 304, PE1 creates a cached list of the received messages based on the add message.

The embodiment of the invention provides a message processing method, which reduces the process that network elements send various protocol messages to an integrated controller for processing by processing periodic refreshing messages through each network element local proxy integrated controller, thereby reducing the processing of the refreshing messages by the integrated controller; interactive processing of protocol messages between the centralized controller and each network element is reduced, and occupation of communication channel bandwidth between the controller and the network elements is reduced; due to the reduction of the processing of the refreshing protocol message by the centralized controller, the utilization rate of a Central Processing Unit (CPU) of the centralized controller is improved, and the occupation of the communication channel bandwidth between the centralized controller and the network element is reduced, so that the centralized controller has a larger control scale on the network element and can control more network element devices.

Referring to fig. 4, fig. 4 is a flowchart of a method for processing a message according to an embodiment of the present invention. As shown in fig. 4, the method comprises the steps of:

step 401, a provider edge PE receives a first message sent by a controller, where the first message at least includes a cache type and a send message;

step 402, searching the sending message in a cache list corresponding to the cache type according to the message type and the service identifier in the sending message;

specifically, when the sending message is an RSVP PATH message or an RSVP RESV message, the service identifier may be a message receiving interface, a source end node IP of the RSVP LSP, a destination end node IP, a Tunnel ID, and an LSP ID.

Searching the sending message in the cache list of the sending message comprises two steps:

searching for a sent message according to the message type and the service identifier, wherein the message type is PATH, and the PATH message has different cache lists for different services;

and after the sending message is found, comparing whether the specific data content is consistent or not.

Step 403, if the sending message is not found in the cache list corresponding to the cache type, the PE creates a cache list of the sending message according to the message type and the service identifier in the sending message;

step 404, the PE adds the data content of the sent message to the cache list of the sent message;

step 405, the PE sends the sending message to a receiving customer edge device CE according to the cache list of the sending message;

Optionally, the method further comprises:

Optionally, the first message further includes an interface identifier for sending the sending message, and a sending period of the sending message;

and the PE sends the sending message to a receiving Customer Edge (CE) in the sending period at the interface for sending the sending message according to the cache list of the sending message.

In this embodiment, the centralized controller sends a message specifying a message buffer to the PE1, the PE1 creates a receiving buffer list of the specified message or a sending buffer list of the specified message according to the message sent by the centralized controller, and the PE1 sends the specified message to the CE1 periodically according to the created sending buffer list of the specified message.

Fig. 5 and fig. 6 are schematic diagrams of a method for processing a message according to an embodiment of the present invention. As shown in fig. 5 and 6, the centralized controller needs to periodically send RSVP protocol refresh message to CE1 based on the established MPLS TE LSP service; the centralized controller constructs RSVP PATH or RSVP RESV refreshing message data based on local LSP data, and determines the sending interface index of RSVP protocol message and the sending cycle duration of RSVP protocol message based on LSP data.

Step 501, the centralized controller sends an add message for creating a cache list for sending a message to edge PE1 of the LSP, where the add message may be a newly defined or newly extended message of OpenFlow, and the add message carries a cache type and an RSVP protocol message, and the RSVP protocol message includes an RSVP protocol message type (RSVP PATH or RSVP RESV) and a service identifier. The adding message can also carry the sending interface index of the RSVP protocol message and the sending period duration of the RSVP protocol message; the Packet _ Out message of OpenFlow may also be employed as the add message.

At step 502, PE1 creates a cache list of the sent messages based on the add message.

After PE1 creates the cache list of the sent message according to the add message, optionally, the method may further include:

step 503, PE1 finds that the cache send message node timer in the cache send message list is overtime; PE1 obtains the content of the cache sending message stored in the cache sending message node, such as RSVP PATH message or RSVP RESV message, finds the corresponding designated sending interface according to the sending interface identifier set in the cache sending message node, and sends out the stored content of the cache sending message RSVPPATH or RSVP RESV;

at step 504, PE1 resets and clears the timer of the cache-sent message node.

The embodiment of the invention provides a message processing method, which completes periodical protocol interaction through each network element proxy controller. Through the local processing of the periodic refreshing messages by each network element, the process that the network elements send various protocol messages to the centralized controller for processing is reduced, so that the processing of the refreshing messages by the centralized controller is reduced, the interactive processing of the protocol messages between the centralized controller and each network element is reduced, and the occupation of the communication channel bandwidth between the controller and each network element is reduced; due to the reduction of the processing of the refreshing protocol message by the centralized controller, the utilization rate of a Central Processing Unit (CPU) of the centralized controller is improved, and the occupation of the communication channel bandwidth between the centralized controller and the network element is reduced, so that the centralized controller has a larger control scale on the network element and can control more network element devices.

Referring to fig. 7, fig. 7 is a flowchart of a method for processing a message according to an embodiment of the present invention. As shown in fig. 7, the method comprises the steps of:

step 701, the centralized controller determines whether the sending message or the receiving message is a periodic refresh message;

optionally, before the centralized controller determines whether the received message is a periodic refresh message, the method further includes:

and the centralized controller receives the receiving message sent by the PE.

Step 702, if yes, the centralized controller sends a first message to a provider edge device PE, where the first message at least includes a cache type and a message content; the message content is the received message or the sent message;

Specifically, the message content of the first message at least includes an interface identifier of the PE receiving the received message, a receiving cycle duration of the received message, a receiving cycle number of the received message, and the received message; or,

Specifically, as shown in fig. 2, the centralized controller sends a message specifying a message cache to PE1, and PE1 creates a receiving cache list of the specified message or a sending cache list of the specified message according to the message sent by the centralized controller; when the PE1 receives a receive message sent by the CE1, the PE1 compares the received receive message with the created receive buffer list, and sends the receive message to the centralized controller if the receive message is not stored in the receive buffer list, or does not forward the receive message to the centralized controller if the receive message is stored in the receive buffer list. The PE1 periodically transmits the specified message to the CE1 according to the transmission buffer list of the specified message that has been created.

Optionally, the first message further includes:

Specifically, the centralized Controller may send an add message to PE1, or send a delete message to PE1, that is, may instruct PE1 to create a cache list of received or sent messages of a specified message, or instruct PE1 to delete the cache list of received or sent messages of the specified message that has been created.
