Description
Technical Field
The present invention relates to an aggregation link switching technique for a distributed link aggregation group, and in particular, to a method, a system, and a node for controlling a packet during aggregation link switching.
Background
With the rapid development of broadband services, the interconnection between networks is used more and more, and more services are carried. Inside the network, there are various methods to protect the link and the node on the link according to the adopted technology. With the increasing demand for protecting traffic, there is a demand for protecting in the network interconnection area by operators. The protection here can be implemented by adopting a port aggregation mode, and a common mode can be port aggregation or loop protection. The loop protection technology is limited by the network topology, and is not applicable to the way of adopting the whole network connection for the interconnection part of the network. Therefore, in order to be applicable to more diversified networking modes of the network and the network interconnection area and realize the protection of not only the link but also the edge node, the IEEE standard organization proposes the extended link aggregation, and realizes the network interconnection protection requirement of link and node dual redundancy through a distributed link aggregation group DRNI, that is, the end point of the aggregation group is composed of a plurality of nodes, and the aggregation links of the nodes form an aggregation link group. As shown in fig. 1, both endpoints A, B of a Link Aggregation Group (LAG) have 2 nodes: a system 1, a system 2, and a system 3, a system 4, wherein a plurality of links of the 4 systems are aggregated together to form an aggregation group LAG, and dual protection of the links and the nodes can be realized through the LAG, where the system 1 and the system 2 in the endpoint a are connected through an inter-link, and the system 3 and the system 4 in the endpoint B are also connected through an inter-link.
In the existing standard 802.1AX, each end point of a link aggregation group only supports a single node, that is, only link aggregation on a single node can be achieved, forming a link aggregation group LAG. The 802.1AX includes a Marker protocol (Marker) for ensuring ordered transmission of messages when switching aggregation links, and the specific process is as follows:
a. the equipment for switching the aggregation link stops sending the service message on the aggregation link;
b. the equipment transmits MarkerPDU to the opposite end equipment of the aggregation link by using a Marker protocol, and starts a timer;
c. the equipment judges whether a Marker responsePDU of the opposite-end equipment is received before the timer is overtime, and if the Marker responsePDU is received, the step d is immediately executed; if not, defaulting that the opposite terminal equipment has received the Marker PDU or has discarded all service messages sent before starting the timer, and executing the step d when the timer is overtime;
the timing time of the timer is selected as much as possible, so that no service message is transmitted on the aggregation link in the timing time.
d. And the equipment for switching the aggregation link distributes the service message on the aggregation link to the new selected aggregation group member port.
The above process is not applicable to the case where the endpoint includes multiple nodes, because the aggregation link switching may be cross-node, if one node receives a Marker protocol message, such as a Marker PDU in the above process, the node cannot guarantee that other nodes in the endpoint where the node is located have completed forwarding the Marker protocol message, and therefore cannot reply to the endpoint.

The following detailed description of the implementation and principles of the method of the present invention is provided in connection with specific embodiments.
Example one
As shown in fig. 4, node A, B and node C, D form a link aggregation group by aggregating links 1 and 2.
Assuming that there is a group of traffic packets sent on the aggregation link 1 in the link aggregation group, the group of traffic packets needs to be switched from the aggregation link 1 for some reasons, such as the aggregation link 1 needs to be isolated from the aggregation group, a new port is added to the aggregation group, or the distributor decides to redistribute the traffic packets on the aggregation link 1 on a group of ports. As shown in fig. 5, the method for controlling a packet when switching an aggregation link in this embodiment includes the following steps:
step 201: the node D stops sending the message from the aggregation link 1, sends a Marker protocol request message to the opposite node A through the aggregation link 1, and starts a timer 1;
step 202: after receiving the Marker protocol request message, the node A sets a node response table item corresponding to the received Marker protocol request message, forwards the Marker protocol request message to a node B in an endpoint of an aggregation group where the node A is located through an internal link, and starts a timer 2;
in this step, forwarding the Marker protocol request message does not affect the flow on the link.
Step 203: after receiving the Marker protocol request message, the node B immediately replies a Marker protocol response message to the node A through an internal link;
step 204: after receiving a Marker protocol response message of a node B before the timeout of a timer 2, the node A sends a Marker protocol response message to a node D through an aggregation link 1;
specifically, a node A records a Marker protocol response message sent by a node B in a node response table item, and when the Marker protocol response message sent by the node B is judged to be recorded in the node response table item before the timeout of a timer 2, a Marker protocol response message is sent to a node D through an aggregation link 1;
the method also comprises the following steps: when the timer 2 times out, the node A judges that the Marker protocol response message sent by the node B is not recorded in the node response table item, the node A defaults that the node B has received the Marker protocol request message, and sends a Marker protocol response message to the node D through the link 1.
Step 205: after receiving the Marker protocol response message of the node A before the timeout of the timer 1, the node D forwards the Marker protocol response message in the endpoint of the aggregation group where the node D is located, and switches the message which is stopped being sent on the aggregation link 1 to the aggregation link 2 to be sent;
the method also comprises the following steps: and if the node D still does not receive the Marker protocol response message of the node A when the timer 1 times out, the default node A receives the Marker protocol request message, forwards the Marker protocol response message in the end point of the aggregation group where the node A is located, and switches the message which is stopped to be sent on the aggregation link 1 to the aggregation link 2 for sending.
Example two
As shown in fig. 6, both ends of the aggregation group are composed of a plurality of nodes, wherein one end of the aggregation group is provided with a node A, B and a node E, and the other end of the aggregation group is provided with a node C, D and a node F, and a link aggregation group is composed by aggregation links 1, 2 and 3.
Assuming that there is a group of traffic packets sent on the aggregation link 1 in the link aggregation group, the group of traffic packets needs to be switched from the aggregation link 1 for some reasons, such as the aggregation link 1 needs to be isolated from the aggregation group, a new port is added to the aggregation group, or the distributor decides to redistribute the traffic packets on the aggregation link 1 on a group of ports. As shown in fig. 7, the method for controlling a packet when switching an aggregation link in this embodiment includes the following steps:
step 301: the node D stops sending the message from the aggregation link 1, sends a Marker protocol request message to the opposite node A through the aggregation link 1, and starts a timer 1;
step 302: after receiving the Marker protocol request message, the node A sets a node response table item corresponding to the received Marker protocol request message, forwards the Marker protocol request message to a node B and a node E in an end point of an aggregation group where the node A is located through an internal link, and starts a timer 2;
step 303: after receiving the Marker protocol request message, the nodes B and E immediately reply a Marker protocol response message to the node A through an internal link;
step 304: after receiving Marker protocol response messages of a node B and a node E before the timeout of a timer 2, a node A sends a Marker protocol response message to a node D through an aggregation link 1;
specifically, a node A records Marker protocol response messages sent by a node B and a node E in a node response table item, and when judging that the Marker protocol response messages sent by the node B and the node E are recorded in the node response table item before a timer 2 is overtime, a Marker protocol response message is sent to a node D through an aggregation link 1;
the method also comprises the following steps: when the timer 2 times out, the node A judges that the Marker protocol response message sent by the node B and/or the node E is not recorded in the node response table item, the node A defaults that the node B and the node E already receive the Marker protocol request message, and sends a Marker protocol response message to the node D through the link 1.
Step 305: after receiving the Marker protocol response message of the node A before the timeout of the timer 1, the node D forwards the Marker protocol response message in the endpoint of the aggregation group where the node D is located, and switches the message which is stopped to be sent on the aggregation link 1 to the aggregation link 2 or 3 to be sent;
the method also comprises the following steps: and if the node D still does not receive the Marker protocol response message of the node A when the timer 1 times out, the default node A receives the Marker protocol request message, forwards the Marker protocol response message in the end point of the aggregation group where the node A is located, and switches the message which is stopped to be sent on the aggregation link 1 to the aggregation link 2 or 3 for sending.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
