Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for collaborative speed limiting of a network device.
Background
In the actual networking, a plurality of network devices with independent intelligent routing functions may be deployed in the same physical area. When each network device forwards traffic, a link on the network device is generally selected as a forwarding link, and the network device cannot realize link optimization and load sharing in a whole area. The collaborative routing networking can enable a plurality of network devices with intelligent routing capability to share link data, and realize centralized scheduling of links by establishing a special forwarding channel.
For network traffic, factors affecting quality of service (English: quality of Service, qoS for short) include bandwidth of transmission, delay of transmission, packet loss rate of data, and so on. In a network, the service quality can be improved by ensuring the transmission bandwidth, reducing the transmission delay, reducing the packet loss rate of data, and the like. Network resources are always limited and the quality of service of certain classes of traffic may be compromised while the quality of service of other traffic is guaranteed. Therefore, the manager needs to reasonably plan and allocate the network resources according to the characteristics of various services, so that the network resources are efficiently utilized.
QoS techniques include flow classification, traffic policing, traffic shaping, speed limiting, congestion management, congestion avoidance, and the like. Among the above QoS techniques, traffic policing, also referred to as speed limiting, refers to policing traffic entering or exiting a network device to protect network resources from damage.
Currently, when traffic of a single tenant across multiple network devices is speed-limited, the problem of traffic doubling occurs. For example, the bandwidth allocated by the operator to the tenant is 10M, and the service traffic of the tenant flows through two network devices. At this time, the total bandwidth used by the tenant reaches 20M, and the bandwidth is doubled. The reason for doubling the actual flow is that: the token buckets of the two network devices are calculated independently, that is, one 10M token bucket is configured in each network device, so that as long as each token bucket contains enough tokens, the two token buckets can output 20M actual traffic.
With the large-scale increase of the number of tenants in a network, the increase of traffic and the expansion of network equipment, the above problems are gradually attracting attention of operators, and new technologies are needed to solve the problems. In the prior art, the flow belonging to the same tenant is drained to the same network equipment through the drainage device, so as to realize speed limitation.
However, the above prior art solutions also expose the following problems: 1) Operators need to purchase the drainage device, so that the cost of the operators is increased; 2) After the drainage device is added in networking, the influence on networking structure is larger, and the performance requirement on the drainage device is higher.

The method for network equipment cooperative speed limiting provided by the embodiment of the application is described in detail below. Referring to fig. 1, fig. 1 is a flowchart of a method for network device collaborative speed limit according to an embodiment of the present application. The method is applied to the first network device, and the method for the network device collaborative speed limit provided by the embodiment of the application can comprise the following steps.
Step 110, when receiving service traffic of a tenant, acquiring a total bandwidth allocated to the tenant and a first actual rate of the service traffic;
specifically, as shown in fig. 2, fig. 2 is a networking schematic diagram of network device cooperative speed limiting provided in the embodiment of the present application. In fig. 2, the first network device and the second network device are both devices for forwarding the same tenant traffic. The link cooperation HUB (HUB) group comprises a first network device and a second network device, and communication interconnection is realized between the first network device and the second network device through cooperation links in the link cooperation HUB group. The cooperative link may be embodied as a TCP connection.
Optionally, the manager configures an initial bandwidth for each network device prior to performing this step.
Further, the manager obtains the total bandwidth allocated by the operator for the tenant, for example, 100M. The manager inputs configuration instructions to the first network device and the second network device respectively in the form of command lines, wherein the configuration instructions comprise initial bandwidths.
The initial bandwidth is the quotient of the total bandwidth and the number of network devices forwarding the same tenant service traffic. In the embodiment of the present application, the total bandwidth is 100M, and the number of network devices forwarding the same tenant service traffic is 2. Thus, the initial bandwidth of each network device is 50M. Each network device automatically configures a bucket depth CBS of a token bucket corresponding to the initial bandwidth according to the initial bandwidth. And each network device forwards the service traffic of the tenant according to the initial bandwidth.
After the first network device is configured in the above manner, when the first network device receives the service traffic of the tenant, the first network device obtains the total bandwidth and the first actual rate of the service traffic.
The first actual rate may be calculated by a tenant rate collection module included in the first network device. The tenant rate collection module counts the number of the messages sent in the nth second and the number of the messages sent in the (n+1) th second. The tenant rate collection module calculates the difference between the number of the n-th second transmitted messages and the number of the n+1th second transmitted messages, and takes the quotient of the difference and 1 second as a first actual rate.
Similarly, when the second network device receives the service traffic of the tenant, the second network device obtains the total bandwidth and a second actual rate of the service traffic.
The second actual rate may be calculated by a tenant rate collection module included in the second network device. The tenant rate collection module counts the number of the messages sent in the nth second and the number of the messages sent in the (n+1) th second. The tenant rate collection module calculates the difference between the number of the n-th second transmitted messages and the number of the n+1th second transmitted messages, and takes the quotient of the difference and 1 second as a second actual rate.
It will be appreciated that the function of the tenant rate collection module to calculate the actual rate is the flow rate statistics function of the flow classification.
For example, in fig. 2, the first actual rate of traffic in the first network device is 200M; the second actual rate of traffic in the second network device is 100M.
Step 120, receiving, by the link in the coordinated HUB group, a first notification message sent by the second network device, where the first notification message includes a second actual rate, and the second actual rate is an actual rate of the service traffic obtained when the second network device receives the service traffic of the tenant;
specifically, according to the description of step 110, after the second network device acquires the second actual rate, a first notification message is generated, where the first notification message includes the second actual rate.
The second network device sends a first notification message to the first network device over the cooperative links in the link cooperative HUB group. And after the first network equipment receives the first notification message, acquiring a second actual rate from the first notification message.
Step 130, calculating a first allocated bandwidth of the first network device according to the total bandwidth, the first actual rate and the second actual rate;
specifically, according to the descriptions of step 110 and step 120, the first network device obtains the total bandwidth, the first actual rate and the second actual rate, and then calculates the first allocated bandwidth of the first network device.
Optionally, the first network device calculates the first allocated bandwidth according to the total bandwidth, the first actual rate and the second actual rate, which specifically includes: the first network device calculates the sum of the first actual rate and the second actual rate; the first network device calculates a quotient of the first actual rate and the sum; the first network device takes the product of the quotient and the total bandwidth as a first allocated bandwidth.
For example, in fig. 2, the total bandwidth is 100M, the first actual rate is 200M, the second actual rate is 100M, and the first allocated bandwidth is 100M (200/(200+100))= 66.666M.
It should be noted that the first allocated bandwidth may be calculated by a tenant rate collection module included in the first network device.
Optionally, in an embodiment of the present application, after the first network device obtains the first actual rate, a second notification message is also generated, where the second notification message includes the first actual rate.
The first network device sends a second notification message to the second network device over the cooperative link in the link cooperative HUB group. The second network device obtains the first actual rate from the second notification message after receiving the second notification message.
Similarly, the second network device calculates its own second allocated bandwidth according to the total bandwidth, the first actual rate and the second actual rate.
For example, in fig. 2, the total bandwidth is 100M, the first actual rate is 200M, the second actual rate is 100M, and the second allocated bandwidth is 100M (100/(200+100))= 33.333M.
The sum of the first allocated bandwidth and the second allocated bandwidth is not greater than the total bandwidth.
And 140, forwarding the received service flow by using the first allocated bandwidth.
Specifically, after the first network device calculates the first allocated bandwidth according to the description of step 130, the bucket depth CBS of the token bucket corresponding to the first allocated bandwidth is automatically adjusted according to the first allocated bandwidth.
It should be noted that, after the tenant rate collection module calculates the first allocated bandwidth, the first allocated bandwidth is transmitted to the tenant bandwidth allocation module included in the first network device. And after the tenant bandwidth allocation module obtains the first allocation bandwidth, adjusting the barrel depth CBS of the token barrel.
Therefore, when receiving the service traffic of the tenant, the first network device acquires the total bandwidth allocated to the tenant and the first actual rate of the service traffic by applying the network device collaborative speed limiting method provided by the application; the method comprises the steps that through a cooperative link in a link cooperative HUB group, first network equipment receives a first notification message sent by second network equipment, wherein the first notification message comprises a second actual rate, and the second actual rate is an actual rate of the acquired service flow when the second network equipment receives the service flow of a tenant; according to the total bandwidth, the first actual rate and the second actual rate, the first network device calculates a first allocated bandwidth of the first network device; and forwarding the received service traffic by the first network equipment by using the first allocated bandwidth.
Thus, the actual rate of the service flow is collected by utilizing the link to cooperate with the HUB group, and the bandwidth of the tenant among all network devices is dynamically allocated, so that the purpose of limiting the speed is achieved. The problems of the current drainage device that the speed limit is realized, the cost is increased and the influence on the networking structure is large are solved.
Optionally, in the embodiment of the present application, a process of adjusting the allocated bandwidth by each network device when the system link in the HUB group of the link system fails is further included.
Specifically, if the cooperative link in the link cooperative HUB group fails, the first network device keeps the first currently calculated allocated bandwidth unchanged; if the failure time exceeds the time threshold, the first network device restores the first allocated bandwidth to the initial bandwidth; and forwarding the received service traffic by the first network equipment by using the initial bandwidth.
The time threshold may be specifically 5 seconds.
In the embodiment of the application, the cooperative links are all TCP connections. The current state of the cooperative link can be known by each network device through the connection and disconnection event reported by the handshake message of the TCP connection. When the first network device acquires a disconnection event, the first network device determines a cooperative link failure and keeps the currently calculated allocated bandwidth unchanged.
The first network device starts a timer and counts the fault event, and if the fault time exceeds a time threshold, the first network device restores the first allocated bandwidth to an initial bandwidth and automatically adjusts the bucket depth CBS of the token bucket.
If the failure time does not exceed the time threshold and the connection event is acquired, the first network device determines that the cooperative link is failed to recover, and at this time, the first network device repeatedly executes the foregoing processes of steps 110 to 140 again, and calculates the current first allocated bandwidth.
Based on the same inventive concept, the embodiment of the application also provides a device for limiting the speed of the network equipment system, which corresponds to the method for limiting the speed of the network equipment system. Referring to fig. 3, fig. 3 is a device for limiting speed of a network device system provided in an embodiment of the present application, where the device is applied to a first network device, the first network device is in a link coordination HUB group, and the link coordination HUB group further includes a second network device, and the device includes:

Optionally, the calculating unit 330 is specifically configured to calculate a sum of the first actual rate and the second actual rate;

and forwarding the received service traffic by utilizing the initial bandwidth.
Optionally, the apparatus further comprises:
