Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

It should be understood that the specific embodiments described herein are merely illustrative of the invention, but do not limit the invention to only some, but not all embodiments.

Referring to fig. 1, fig. 1 is a flowchart of steps of a method for processing a packet according to an embodiment of the present invention, where the method may be executed in a first router, and the method in this embodiment includes the following steps:

step 101, obtaining a target message, wherein the target message is an Ethernet data message.

The target packet may be an ethernet data packet directly acquired through an ethernet physical interface of the first router, and the ethernet data packet may be an ethernet broadcast packet or an ethernet multicast packet. Or the target message is an ethernet data message obtained by analyzing the video networking multicast message received through the video networking physical interface by the first router.

And 102, determining a first target port corresponding to the target message.

And if the target message is acquired through the Ethernet physical interface of the first router, the first target port corresponding to the target message is the Ethernet physical interface.

If the target message is obtained after the first router analyzes the video networking multicast message received through the video networking physical interface, whether a tunnel corresponding to the number of the opposite-end router and the sub-number of the opposite-end router exists or not is determined according to the number of the opposite-end router and the sub-number of the opposite-end router included in the video networking multicast message, and the tunnel is used as a first target port under the condition that the tunnel corresponding to the number of the opposite-end router and the sub-number of the opposite-end router exists.

Step 103, traversing each port except the first target port in the forwarding instance to which the first target port belongs to determine the number of tunnels of the first target tunnel in the forwarding instance.

There may be one forwarding instance on a router, or multiple forwarding instances, each of which may include at least one physical interface and/or at least one tunnel. After step 102 is performed, each port except the first destination port in the forwarding instance to which the first destination port belongs may be traversed. For example, the forwarding instance includes 3 ports, port 1 (tunnel 1), port 2 (tunnel 2), and port 3 (ethernet physical interface). If the ethernet physical interface receives the ethernet data packet, the ethernet physical interface is the first target port, and since the ethernet physical interface belongs to the forwarding example, port 1 and port 2 in the forwarding example need to be traversed, so that it can be determined that the number of tunnels of the first target tunnel in the forwarding example is equal to 2, and the first target tunnel in the forwarding example is tunnel 1 and tunnel 2.

And 104, encapsulating the target message according to the first tunnel information and a preset encapsulation format of each first target tunnel to obtain a first video networking multicast message under the condition that the number of the tunnels is more than 1.

Combining the example in the above step, since the number of tunnels is 2, that is, the number of tunnels is greater than 1, the target packet is encapsulated according to the first tunnel information and the preset encapsulation format of each first target tunnel, so as to obtain the first multicast packet of the video network.

Step 105, sending the first video networking multicast message to the video networking server.

In step 104, when there are multiple tunnels in all ports in the forwarding instance to which the first target port corresponding to the target packet belongs, the target packet is encapsulated to obtain a multicast packet of the video networking, and the multicast packet of the video networking is sent to the video networking server once, so that compared with the prior art in which multiple tunnels exist, the number of times of sending packets to the video networking server can be reduced when multiple user packets need to be sent to the video networking server, thereby reducing the bandwidth occupied by the video networking.

In addition, it should be noted that, in the prior art, if there are multiple tunnels, the video networking server needs to receive multiple user packets and needs to forward multiple user packets. In this example, the video networking multicast message is sent to the video networking server only once when there are a plurality of tunnels, so that the video networking server only needs to receive the video networking multicast message once, and the video networking server only forwards the video networking multicast message once to the multicast group to which the first router belongs, thereby reducing the forwarding burden of the video networking server.

The message processing method provided in this embodiment determines, by acquiring a target message, where the target message is an ethernet data message, a first target port corresponding to the target message, traverses each port except the first target port in a forwarding example to which the first target port belongs, to determine the number of tunnels of a first target tunnel in the forwarding example, and encapsulates the target message according to first tunnel information and a preset encapsulation format of each first target tunnel when the number of tunnels is greater than 1, to obtain a first multicast message of the internet of view, and sends the first multicast message of the internet of view to the server of the internet of view. Therefore, under the condition that a plurality of tunnels exist in all ports in a forwarding example to which a first target port corresponding to a target message belongs, the target message is packaged to obtain a video networking multicast message, and the video networking multicast message is sent to a video networking server once, so that the times of sending the message to the video networking server can be reduced, and the condition of occupied video networking bandwidth is further reduced.

It should be noted that, if each port except the first destination port in the forwarding example to which the first destination port belongs is traversed, if one of the traversed ports is an ethernet physical interface, a copy of the destination packet is directly copied, and the copied destination packet is sent through the ethernet physical interface. For example, the forwarding example includes 4 ports, that is, port 1 (tunnel 1), port 2 (tunnel 2), port 3 (ethernet physical interface 1), and port 4 (ethernet physical interface 2), and when traversing to port 4, directly copies a target packet and sends the target packet through port 4. And if the number of the tunnels of the first target tunnel in the forwarding example is equal to 1, directly copying a target message and sending the copied target message through the first target tunnel.

Optionally, the first tunnel information includes a number of the first router, a sub-number of the first router, a number of a first peer router of the first router, and a sub-number of the first peer router, where the first peer router is a router having a first target tunnel established between itself and the first router;

the preset packaging format comprises the following steps: a first data position corresponding to the number of the second opposite end router, a second data position corresponding to the number of each second opposite end router, a third data position corresponding to the number of the sub-numbers of each second opposite end router, a fourth data position corresponding to the sub-numbers of each second opposite end router, and a fifth data position corresponding to the received broadcast message or multicast message, wherein the second opposite end router comprises any opposite end router of routers acquiring the Ethernet data message;

according to the first tunnel information and the preset encapsulation format of each first target tunnel, encapsulating the target message to obtain a first video network multicast message, comprising:

the method comprises the steps of filling and writing the number of first peer routers to a first data position, filling and writing the number of each first peer router to a second data position, filling and writing the number of sub-numbers of each first peer router to a third data position, filling and writing the sub-numbers of each first peer router to a fourth data position, and filling and writing a target message to a fifth data position to obtain a first video networking multicast message.

It should be noted that the number of the second peer router may be represented by a binary number of one byte (8 bits), each second peer router number may be represented by a binary number of four bytes (i.e., 32 bits), each second peer router sub-number may be represented by a binary number of one byte (8 bits), and each second peer router sub-number may be represented by a binary number of one byte (8 bits).

First, an exemplary description of the first tunnel information is provided herein to describe the process of obtaining the first multicast packet in detail. For example, referring to fig. 2 and fig. 3, fig. 2 is a system architecture diagram provided in an embodiment of the present invention, and fig. 3 is a schematic diagram of tunnel information of a tunnel established between routers provided in an embodiment of the present invention. For example, a tunnel 1 is established between the router 1 and the router 2, and if the number of the router 1 is 111, the local sub-number of the router 1 corresponding to the tunnel 1 is 11; the number of router 2 is 222, and the sub-number of router 2 corresponding to tunnel 1 locally to router 2 is 22. If the number of the router 1 is 111 and the sub-number of the router 1 corresponding to the tunnel 1 in the router 1 is 11, the tunnel information of the tunnel 1 established between the router 1 and the router 2 stored in the router 1 is 1111122222, and the tunnel information of the tunnel 1 established between the router 2 and the router 1 stored in the router 2 is: 2222211111.

for example, a tunnel 2 and a tunnel 3 are established between the router 1 and the router 3. If the local sub-number of the router 1 corresponding to the tunnel 2 of the router 1 is 22, the sub-number of the router 1 corresponding to the tunnel 3 is 33; if the number of the router 3 is 333, the sub-number of the router 3 corresponding to the tunnel 2 in the router 3 is 44, and the sub-number of the router 3 corresponding to the tunnel 3 in the router 3 is 55, the tunnel information of the tunnel 2 established between the router 1 and the router 3 stored in the router 1 is 1112233344, and the tunnel information of the tunnel 3 established between the router 1 and the router 3 stored in the router 1 is 1113333355.

Take the router 1 as the first router and the ethernet physical interface of the router 1 receives the ethernet data packet as an example. If the ethernet physical interface and the tunnel 1, the tunnel 2, and the tunnel 3 belong to the forwarding instance 1, the tunnel 2, and the tunnel 3 may all be the first target tunnel, the number of the first target tunnel is equal to 3, the first tunnel information of the tunnel 1 is 2222211111, the first tunnel information of the tunnel 2 is 1112222244, and the first tunnel information of the tunnel 3 is 1113322255. The first peer routers are router 2 and router 3. If the ethernet physical interface and the tunnel 1 belong to the forwarding instance 2, and the tunnel 2 and the tunnel 3 belong to the forwarding instance 3, only the tunnel 1 is the first target tunnel, and the first peer router is the router 2.

The foregoing describes the first tunnel information exemplarily, and next, the following describes that the target packet is encapsulated according to the first tunnel information of each first target tunnel and a preset encapsulation format to obtain the first multicast packet of the video network.

Taking the router 1 as the first router as an example, when the tunnel 1, the tunnel 2 and the tunnel 3 are all the first target tunnels, the number of the first peer router includes the number of the router 2 and the number of the router 3, that is, the number of the first peer router is equal to 2; the number of the router 2 is 222, the sub-number of the router 2 is 22, the number of the router 3 is 333, and the sub-numbers of the routers 3 are 44 and 55, then the first data location may be filled with 2, the second data location 1 may be filled with 222, the third data location 1 may be filled with 1, the fourth data location 1 may be filled with 22, the second data location 2 may be filled with 333, the third data location 2 may be filled with 2, the fourth data location 2 may be filled with 44, the fourth data location 3 may be filled with 55, and the fifth data location is filled with an ethernet data packet (target packet), that is, the filled data is [2] - [222] [1] [22] - [333] [2] [44] [55] - [ target packet ], so as to complete the encapsulation of the target packet, and obtain the first view networking multicast packet.

Optionally, step 101, obtaining the target packet may be implemented by the following method:

acquiring a first Ethernet data message through an Ethernet physical interface of a first router;

as shown in fig. 2 and 3, the router 1 is still used as the first router. For example, a computer is connected to the ethernet physical interface of the router 1, and when the computer sends an ethernet data packet to the ethernet physical interface, the router 1 may receive the ethernet data packet through the ethernet physical interface, and use the received ethernet data packet as a target packet. Correspondingly, the step 102 of determining the first target port corresponding to the target packet may be implemented by the following steps:

the ethernet physical interface is taken as the first destination port.

Optionally, step 101, obtaining the target packet may also be implemented by the following steps:

acquiring a second video networking multicast message through a video networking physical interface of a first router, wherein the second video networking multicast message is acquired after an Ethernet physical interface of the second router receives a second Ethernet data message and is acquired after the second Ethernet data message is encapsulated according to second tunnel information and a preset encapsulation format of each second target tunnel, the second target tunnel is a tunnel in each port in a forwarding example to which the Ethernet physical interface of the second router belongs, and the second tunnel information comprises the number of the second router, the sub-number of the second router, the number of a third opposite-end router of the second router and the sub-number of the third opposite-end router;

analyzing the second video networking multicast message to obtain the number of the third opposite-end router, the sub-number of the third opposite-end router and a second Ethernet data message;

searching whether a tunnel corresponding to the number of the third opposite-end router and the sub-number of the third opposite-end router exists or not according to the number of the third opposite-end router and the sub-number of the third opposite-end router;

and under the condition that tunnels corresponding to the number of the third opposite-end router and the sub-number of the third opposite-end router exist, if the number of the third target tunnels in the port of the forwarding example to which the tunnels corresponding to the number of the third opposite-end router and the sub-number of the third opposite-end router belong is more than 1, taking the second Ethernet data message as the target message.

Correspondingly, the step 102 of determining the first destination port corresponding to the destination packet may be implemented by the following steps:

and taking the tunnel corresponding to the number of the third opposite-end router and the sub-number of the third opposite-end router as the first target port.

It should be noted that, referring to fig. 2 and fig. 3, if the router 2 serves as a second router, and the ethernet physical interface of the router 2 receives an ethernet datagram (i.e. a second ethernet datagram), the router 2 may perform the same operation as the router 1, that is, traverse each port in the forwarding instance to which the ethernet physical interface belongs, to determine the number of tunnels of ports belonging to tunnels in each port in the forwarding instance, that is, determine the number of tunnels of a second target tunnel, and in a case that the number of tunnels of the second target tunnel is greater than 1, encapsulate the second ethernet datagram according to the second tunnel information and the preset encapsulation format of each second target tunnel to obtain a second internet-of-view multicast datagram (a specific encapsulation method may refer to the illustration in the above embodiment, if a tunnel 4 is established between the router 2 and the router 4, the tunnel information of the tunnel 4 established between the router 2 and the router 4, which is stored locally in the router 2, is, for example: 2223344411, if the ethernet physical interface of the router 2, the tunnel 1 and the tunnel 4 belong to the same forwarding instance, the second target tunnel is the tunnel 1 and the tunnel 4, and the number of the second target tunnel is 2, so that the condition of encapsulating the second ethernet data packet is satisfied, and the encapsulated second view network packet is: [2] - [111] [1] [11] - [444] [1] [44] - [ second ethernet data packet ]), then send the second multicast message of the video networking to the server of the video networking, the server of the video networking sends the second multicast message of the video networking to the multicast group that router 2 belongs to, if router 1, router 2, router 4 and router 5 belong to the same multicast group, router 1, router 2, router 4 and router 5 can all receive the second multicast message of the video networking.

Taking the router 1 as the first router as an example for illustration, after the router 1 receives the second multicast packet through the physical interface of the video network connected to the video network server, the router 1 may parse the second multicast packet, and then search for the tunnel corresponding to 11111 (since the third peer router of the router 2 includes the router 1 and the router 4, that is, the router 1 searches for the tunnel corresponding to the number 111 of the router 1 and the sub-number 11 of the router 1), since the tunnel 1 corresponds to both the number 111 of the router 1 and the sub-number 11 of the router 1, the tunnel 1 may be searched for the second ethernet data packet as the target packet, and subsequent steps 102 to 105 are performed.

In the process of executing steps 102 to 105, if the forwarding example to which the tunnel 1 belongs is the forwarding example 1 (the forwarding example 1 includes an ethernet physical interface, tunnel 1, tunnel 2, and tunnel 3), that is, the third target tunnel is the tunnel 1, tunnel 2, and tunnel 3, and the number of tunnels of the third target tunnel is equal to 3, the second ethernet data packet obtained by analysis is used as the target packet. If the tunnel 2, the tunnel 3 and the tunnel 1 do not belong to one forwarding instance, the tunnel 1 and the ethernet physical interface belong to the same forwarding instance a, and only one tunnel (namely the tunnel 1) exists in the forwarding instance, directly copying a second ethernet data packet, and sending the second ethernet data packet through the tunnel 1. If the router 1 traverses each port in the forwarding instance a, when traversing the ethernet physical interface, it may directly copy a second ethernet datagram and send the second ethernet datagram through the ethernet physical interface.

It should be noted that, if the router 1 receives the video networking multicast packet sent by the router 4, because a tunnel is not established between the router 1 and the router 4, the router 1 cannot search for a tunnel corresponding to both the number of the opposite-end router of the router 4 and the sub-number of the opposite-end router, and in this case, the router 1 may directly discard the received video networking multicast packet.

Optionally, step 103, traversing each port except the first destination port in the forwarding instance to which the destination port belongs to determine the number of tunnels of the first destination tunnel in the forwarding instance may be implemented by the following steps:

under the condition that a second target port in each traversed port is a tunnel, accumulating 1 for the current number of the tunnels in each port, and judging whether each port is traversed according to the number of all ports in a forwarding example and the number of traversed ports;

and under the condition of traversing each port, taking the current number after 1 accumulation as the number of tunnels.

For example, in the case where the router 1 is used as the first router, the port 1 (ethernet physical interface 1), the port 2 (tunnel 1), the port 3 (tunnel 2), the port 4 (tunnel 3), and the port 5 (ethernet physical interface 2) of the router 1 belong to the same forwarding instance. If the ethernet physical interface 1 of the router 1 receives the target packet in step 101, traversing the port 2, the port 3, the port 4, and the port 5, where the initial value of the number of tunnels of the forwarding instance (i.e., the number of tunnels belonging to the forwarding instance) is 0, the number of ports of the forwarding instance is 5, and when traversing to the port 2 of the forwarding instance, where the port 2 is a tunnel, adding 1 to the initial value, that is, the current number is equal to 1; when traversing the port 3, the port 3 is a tunnel, and the current number is equal to 2 after accumulating 1; when traversing the port 4, the port 4 is a tunnel, and the current number is equal to 3 after accumulating 1; when traversing the port 5, the port 5 belongs to an ethernet physical interface, and the final current number is equal to 3, that is, the number of tunnels of the forwarding instance is equal to 3.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a message processing apparatus according to an embodiment of the present invention, where the apparatus is disposed in a first router, and includes:

the preset packaging format comprises the following steps: a first data position corresponding to the number of a second opposite end router, a second data position corresponding to the number of each second opposite end router, a third data position corresponding to the number of sub-numbers of each second opposite end router, a fourth data position corresponding to the sub-number of each second opposite end router, and a fifth data position corresponding to a received broadcast message or multicast message, wherein the second opposite end router comprises any opposite end router of a router for acquiring the Ethernet data message;

The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

the network interface module 601, the CPU module 603, and the disk array module 604 all enter the switching engine module 602; the switching engine module 602 performs an operation of looking up the address table 605 on the incoming packet, thereby obtaining the direction information of the packet; and stores the packet in a queue of a corresponding packet buffer 606 according to the packet's steering information; if the queue of the packet buffer 606 is nearly full, it is discarded; the switching engine module 602 polls all packet buffer queues and forwards if the following conditions are met: 1) the port send buffer is not full; 2) the queue packet counter is greater than zero. The disk array module 604 mainly implements control over the hard disk, including initialization, read-write, and other operations of the hard disk; the CPU module 603 is mainly responsible for protocol processing with an access switch and a terminal (not shown in the figure), configuring an address table 605 (including a downlink protocol packet address table, an uplink protocol packet address table, and a data packet address table), and configuring the disk array module 604.

The access switch:

2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA SA Reserved Payload CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA SA Reserved Label Payload CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
