Embodiment
Referring to Fig. 1, is the group-network construction figure in a kind of illustrative embodiments of the present invention, and wherein, user A, user B carry out access network by common interface P1 on switch, and user C is by common interface P2 access network on switch.In prior art, the situation that meeting buys flow bandwidth according to user usually arranges different Session-group.Such as, suppose that user A and user C have purchased 100M bandwidth, user B have purchased 50M bandwidth, and so can add in the Session-group corresponding to 100M bandwidth by user A and user C, user B is then added in Session-group corresponding to 50M bandwidth.In traditional switch, all can access same interface with the user in a Session-group, therefore can over that interface for the user in this Session-group carries out speed limit.
But due to user access uncontrollability, likely occur that the user in same Session-group accesses the situation of distinct interface, as shown in Figure 1, belong to the user A of same Session-group and user C respectively by interface P1 and P2 access network, therefore cause switch cannot carry out speed limit by conventional method to user A and user C, thus affect Consumer's Experience.
In order to solve the problem, the present invention can by searching the user belonging to same Session-group, for Session-group distributes one-level CAR (Committed Access Rate, committed access rate), and secondary CAR is set for each user in Session-group, then the qos policy with secondary CAR is issued to the interface of each user access, the interface of switch therefore can be made to carry out speed limit according to secondary CAR to user, thus promote Consumer's Experience.
Please refer to Fig. 2, be the process chart of a kind of network speed limit method in a kind of illustrative embodiments of the present invention, described method is applied to switch, and described switch comprises multiple interface, and described method comprises:
Step 201, in total interface, search the user belonging to same Session-group;
In the present embodiment, when each interface of switch receives the flow of different user transmission, switch can search from total interface the user belonging to same Session-group, and wherein the promise flow bandwidth of each user can not be identical.In optional embodiment of the present invention, switch by obtaining the packet label carried in each customer flow, and can add customer flow identical for packet label to same Session-group.So-called packet label can be the VLAN ID (Virtual Local AreaNetwork Identification, VLAN identify label) of this user, the priority of user etc.
Step 202, be that described Session-group distributes one-level CAR;
In the present embodiment, switch can be consistent for the promise flow bandwidth that the value of Session-group distribution one-level CAR, usual one-level CAR is corresponding with this Session-group.
Step 203, each user be respectively in described Session-group according to described one-level CAR configure corresponding QoS policy, and described qos policy comprises secondary CAR corresponding to user;
In the present embodiment, switch can configure qos policy for each user in described Session-group, and this qos policy comprises secondary CAR corresponding to this user.Wherein this secondary CAR is used for the access to netwoks speed of limited subscriber, and this secondary CAR corresponding to each user can not be identical.Further, can also comprise user tag in described qos policy, distinguishing this user tag of different user to make interface by user tag can be the information such as IP address, MAC Address.In optional embodiment of the present invention, switch can based on described one-level CAR, according to the weighted value for each user preset, for user distributes corresponding secondary CAR.And because the promise flow bandwidth of each user can not be identical, then the weighted value of each user preset is not identical yet.Such as Session-group comprises two users, and one-level CAR is 10M, and the weighted value that the weighted value of first user is 1, second user is 3, and the secondary CAR that so first user is corresponding is 2.5M, and secondary CAR corresponding to second user is 7.5M.
Step 204, qos policy corresponding for user is issued to the interface of this user access, according to the secondary CAR in described qos policy, speed limit carried out to this user to make described interface.
After QoS has configured, it can be issued on the interface of user's access in this Session-group by switch respectively, carries out speed limit with the secondary CAR making interface corresponding according to user to user.Therefore switch can carry out speed limit to the user that distinct interface accesses same Session-group.
As can be seen here, the present invention can by searching the user belonging to same Session-group, for Session-group distributes one-level CAR, and secondary CAR is set for each user in Session-group, then the qos policy with secondary CAR is issued to the interface of each user access, therefore the interface of switch can be made to carry out speed limit according to secondary CAR to user, thus promote Consumer's Experience.
In order to strengthen the applicability of switch, for actual conditions during switch configuration qos policy, can also improve embodiment of the present invention with reference to following examples.
In optional embodiment of the present invention, when the certain customers in Session-group fail the metered flow bandwidth used completely in the secondary CAR of self correspondence for various reasons, in this Session-group, then residual flow can be produced.Now, described residual flow according to the weighted value preset, can be distributed to the user not producing residual flow in this Session-group by switch.For example, described in embodiment as the aforementioned, secondary CAR corresponding to first user is 2.5M, and secondary CAR corresponding to second user is 7.5M.When first user only employs 2M, so remaining 0.5M can be distributed to second user by switch, so second user just can use 8M bandwidth, thus on the basis ensureing the normal utilized bandwidth of each user, by remaining allocated bandwidth to the more user of business demand, thus the access rate of user can be improved according to the actual conditions of bandwidth.
In optional embodiment of the present invention, when reaching the standard grade when there being user in Session-group or roll off the production line, switch can also reconfigure qos policy for online each user in described Session-group.For example, described in embodiment as the aforementioned, secondary CAR corresponding to first user is 2.5M, and secondary CAR corresponding to second user is 7.5M.When first user offline, so the bandwidth of 10M is just all distributed to second user by switch, obtains more bandwidth traffic to make second user.Otherwise if when having third party to reach the standard grade, this exchange opportunity is that each user distributes the 2nd corresponding CAR according to the weighted value of each user again.The present invention adjusts the allocated bandwidth situation in qos policy in real time according to the situation of reaching the standard grade of user, thus can improve the applicability of switch, promotes bandwidth effective rate of utilization.
In addition, when all use in described Session-group roll off the production line per family, a CAR corresponding for described Session-group and qos policy corresponding to user can delete by described switch, therefore can reduce the cache resources taking each interface.
For making object of the present invention, technical scheme and advantage clearly understand, below based on the group-network construction of Fig. 1, scheme of the present invention is described in further detail.
As shown in Figure 1, user A, user B carry out access network by common interface P1 on switch, and user C is by common interface P2 access network on switch.When user is respectively to switch transmitted traffic, the network speed limit handling process of switch as shown in Figure 3, comprising:
The flow that step 301, reception user send;
Switch receives user A, user B respectively by interface P1 and P2, user C sends flow A, flow B, flow C;
Step 302, search the user belonging to same Session-group according to the user tag in flow;
Switch obtains the packet label in flow A, flow B, flow C respectively, i.e. VLAN ID, and determines according to VLAN ID the user belonging to same Session-group.Suppose that the VLANID of flow A is VLAN-1, the VLAN ID of flow B is VLAN-2, and the VLAN ID of flow C is VLAN-1, so can determine that user A and user C belongs to Session-group1; User B belongs to Session-group2.
Step 303, the one CAR is set for Session-group;
The promise flow bandwidth that switch is corresponding according to each Session-group is the CAR that each Session-group arranges its correspondence.Suppose that promise flow bandwidth that Session-group1 is corresponding be the promise flow bandwidth that 100M, Session-group2 are corresponding is 50M, the CAR that so Session-group1 is corresponding is the CAR that 100M, Session-group2 are corresponding is 50M.
Step 304, be that each user in Session-group configures qos policy according to a CAR, according to the weighted value of each user for this user distributes the 2nd CAR;
Switch is after each Session-group arranges a CAR, can configure qos policy for each user in Session-group.This qos policy comprises the user tag of user and the secondary CAR of correspondence thereof.Wherein suppose that user tag is the MAC Address of user.Switch can based on described one-level CAR, according to the weighted value for each user preset, for user distributes corresponding secondary CAR.Suppose, the weighted value of user A and user C is respectively 1 and 3, and the secondary CAR that so user A is corresponding is 25M, and the secondary CAR that user C is corresponding is 75M.The qos policy that then in Session-group1, user A and user C is corresponding is as shown in table 1.
| User | User tag | 2nd CAR |
| User A | MAC A | 25M |
| User C | MAC C | 75M |
Table 1
In like manner, switch can also configure qos policy for the user in Session-group2.Owing to only having user B at present in Session-group2, so the 2nd CAR of this user B is 50M.
Step 305, described qos policy is issued to the interface of each user's access in described Session-group.
The qos policy configured is dealt on P1 and P2 by switch respectively, carries out speed limit with the customer flow making P1, P2 can manage self according to qos policy.
As can be seen here, the present invention can by searching the user belonging to same Session-group, for Session-group distributes one-level CAR, and secondary CAR is set for each user in Session-group, then the qos policy with secondary CAR is issued to the interface of each user access, therefore the interface of switch can be made to carry out speed limit according to secondary CAR to user, thus promote Consumer's Experience.
