Embodiment
Suppose that CE1, CE2 and CE3 belong among the VPN based on Hose flexible pipe VPN as shown in Figure 1 for given one, link to each other with PE3 with PE1, the PE2 of provider's network with Hose3 by Hose1, Hose2 respectively; PE1, PE2 and PE3 in provider's network route and algorithm not in the middle of considering; Current being under the default conditions, Hose flexible pipe upstream and downstream bandwidth determine that provider's network guarantees that user Hose flexible pipe up-downgoing data transmit on the basis, optimize the bandwidth resources between PE1, PE2 and the PE3; The increasable upstream and downstream bandwidth capacity of Hose1, Hose2 and Hose3 is 20M; Suppose the threshold value B that bandwidth is adjusted
ThBe 1M.
We suppose that the transmission DCU data control unit in the CE1 user bandwidth control unit detects lot of data and will send CE2 and CE3, need increase the bandwidth capacity of 10M and 8M respectively to CE2 and CE3 on current basis.Owing to the threshold value B of the bandwidth capacity that will increase greater than our defined to CE2, CE3
Th: 1M and sum are less than the increasable bandwidth 20M of Hose flexible pipe, so entering to increase, the transmission data cell state machine of CE1 sends bandwidth mode (as shown in Figure 3), send the bandwidth query messages to PE1 (as shown in Figure 5), the bandwidth capacity that inquiry provider network can use.The general data form of bandwidth inquiry, control and response message as shown in Figure 7, comprise source address, destination address, message attributes, far-end CE address and adjust size field that wherein message attributes is divided into bandwidth inquiry and response message, bandwidth increase control and response message, the transmission bandwidth reduces and response message and the little and response message of receiving belt reductions; Far-end CE address is that sky shows and only adjusts local terminal flexible pipe bandwidth.The bandwidth query messages that bandwidth CE1 sent as shown in Figure 8, source, destination address are corresponding to CE1, PE1 address, message attributes is corresponding to the bandwidth query messages, the adjustment size field of far-end CE2, CE3 correspondence is respectively 10M, 8M.
PE1 is after receiving the bandwidth Query Information, and finding corresponding provider's network terminal according to far-end CE2, CE3 address is respectively PE2, PE3, and therefore, can the network inquiry PE1 of provider to the bandwidth resources that increase 10M, 8M between PE2, the PE3 respectively.We suppose PE1 to increasing the 10M capacity between the PE2, and to increasing the 5M bandwidth capacity between the PE3, then PE1 returns the bandwidth inquiry request response message to CE1 end (as shown in Figure 5).The bandwidth inquiry request response message that PE1 returns as shown in Figure 9, source, destination address are corresponding to PE1, CE1 address, message attributes is corresponding to the bandwidth inquiry request response message, the adjustment size field of far-end CE2, CE3 correspondence is respectively 10M, 5M.
After CE1 receives the bandwidth inquiry request response message of provider's network,, be determined to the increase bandwidth capacity of far-end CE according to the increased bandwidth resources situation of provider's network.In this example, CE1 increases the bandwidth 10M to CE2, increases the bandwidth 5M to CE3, and sends bandwidth to CE2 and CE3 respectively by own VPN and adjust solicitation message (as shown in Figure 5), applies for being increased to this VPN user's bandwidth capacity.Bandwidth is adjusted solicitation message and is transmitted by the VPN internal network, and middle provider network is done transparent transmission to the VPN internal data.The general data form of bandwidth adjustment application and response message comprises source address, destination address, message attributes, adjustment attribute and adjusts size as shown in Figure 8.Adjust solicitation message as shown in figure 17 for the bandwidth that mails to CE2, source, destination address are corresponding to CE1, CE2 address, and message attributes is that bandwidth is adjusted solicitation message, adjusts attribute for increasing, and adjusting size is 10M; Adjust solicitation message as shown in figure 18 for the bandwidth that mails to CE3, source, destination address are corresponding to CE1, CE3 address, and message attributes is that bandwidth is adjusted solicitation message, adjusts attribute for increasing, and adjusting size is 5M.
In the CE2 of far-end, CE3 user bandwidth control unit, after the reception DCU data control unit receives the bandwidth adjustment request message of CE1 transmission, receive DCU data control unit and enter increase reception data pattern (as shown in Figure 4), according to reception and the disposal ability of oneself, definite reception capacity that will increase, and return bandwidth adjustment request response message (as shown in Figure 5), and adjust the receiving belt tolerance of corresponding Hose flexible pipe.We suppose CE2, and the reception bandwidth that CE3 can increase is respectively 8M, 10M, bandwidth capacity according to the increase of the application in the bandwidth solicitation message, the bandwidth that CE2, CE3 finally determine to increase is respectively 8M, 5M, and the reception bandwidth of adjusting Hose1, Hose2 flexible pipe respectively is respectively 8M, 5M.Corresponding to the bandwidth adjustment application response message of CE2 as shown in figure 19, source, destination address are respectively CE2, CE1 address, and message attributes is a bandwidth adjustment application response message, adjust attribute for increasing, and adjusting size is 8M; Corresponding to the bandwidth adjustment application response message of CE3 as shown in figure 20, source, destination address are respectively CE3, CE1 address, and message attributes is a bandwidth adjustment application response message, adjust attribute for increasing, and adjusting size is 5M.
After CE1 received the bandwidth adjustment request response message, according to the increase bandwidth capacity that CE2, CE3 finally determine, sending the bandwidth control messages increased bandwidth capacity to the PE1 application.The bandwidth control messages as shown in figure 10, corresponding source, destination address are respectively CE1, PE1 address, message attributes is that bandwidth increases control messages, the adjustment size field of CE2 correspondence is 8M, the adjustment size field of CE3 correspondence is 5M.
PE1 is after receiving the bandwidth control messages, adjust the bandwidth capacity of provider's network PE 1 to PE2 and PE3 interface, increase the Hose flexible pipe inlet capacity 13M of PE1, increase Hose flexible pipe egress capacity 8M, the 5M of PE2, PE3 respectively, and return bandwidth control response message as shown in figure 11, and corresponding source, destination address are respectively PE1, CE1 address, and message attributes is that bandwidth increases the control response message, the adjustment size 8M of CE2 correspondence, the adjustment size of CE3 correspondence is 5M.
CE1 increases Hose flexible pipe bandwidth 13M after receiving bandwidth adjustment response message, the beginning high amount of traffic sends data.
After we supposed elapsed time T, the flow that CE1 mails to CE2 had reduced 2M, and the data traffic that mails to CE3 does not change.In a timer cyclic process, CE1 detects needs to send the transmission band bandwidth 2M of data bandwidth less than the Hose1 flexible pipe, because this value is greater than judgement threshold value B
Th, the transmission data cell of CE1 enters and reduces to send bandwidth mode (as shown in Figure 3).Because the Hose1 flexible pipe of CE1 sends bandwidth greater than default configuration at present, so at first reducing the Hose1 flexible pipe, CE1 sends bandwidth, and the wide control messages of hair band is to PE1 then, and application reduces the transmission bandwidth of Hose1 flexible pipe.This bandwidth control messages as shown in figure 12, corresponding source, destination address are respectively CE1, PE1 address, message attributes reduces control messages for sending bandwidth, far-end CE address corresponds to sky, the adjustment size field is 2M.
PE1 is after receiving the bandwidth control messages, and according to the requirement of control messages, the Hose1 flexible pipe that reduces the PE1 correspondence is gone into port band width 2M, and the walking along the street of going forward side by side is optimized provider's Internet resources by upgrading with algorithm.After the requirement of finishing the CE1 control messages, return bandwidth control response message.This bandwidth is controlled response message as shown in figure 13, and corresponding source, destination address are respectively PE1, CE1 address, and message attributes reduces control messages for sending bandwidth, and far-end CE address is empty, and the adjustment size field is 2M.
In the data while that CE1 reduces to mail to CE2, the reception DCU data control unit of CE2 detects the reception bandwidth 2M of the data traffic of current reception less than the Hose2 flexible pipe in a timing cycle, because this value is greater than judgement threshold value B
Th, the reception DCU data control unit enters and reduces to receive data pattern (as shown in Figure 4).Because current Hose2 flexible pipe receives data bandwidth and is far longer than default value, application reduces to receive data bandwidth so CE2 reception DCU data control unit transmits control message.This control messages as shown in figure 14, corresponding source, destination address are respectively CE2, PE2 address, message attributes is the little control messages of receiving belt reductions, far-end CE address corresponds to sky, the adjustment size field is 2M.
PE2 according to the control messages requirement, reduces the Hose2 flexible pipe outlet bandwidth 2M of PE2 correspondence after receiving the bandwidth control messages, the walking along the street of going forward side by side is optimized provider's Internet resources by renewal.After the message of finishing CE2 requires, return bandwidth control response message.This bandwidth is controlled response message as shown in figure 15, and corresponding source, destination address are respectively PE2, CE2 address, and message attributes is the little control messages of receiving belt reductions, and far-end CE address is empty, and the adjustment size field is 2M.
In controlled model, the increase bandwidth only need send data terminal and transmit control message, and provider's network is finished the configuration to the hose connection of each client; Reducing bandwidth needs each interface to detect the information that need reduce automatically, transmits control message respectively, reduces the transmission of each hose connection or receives bandwidth.
In the present invention, each VPN user can increase Hose flexible pipe bandwidth again on the basis that increases Hose flexible pipe bandwidth, concrete operations and above example are together, and be final if each VPN user does not send data, and the transmission of Hose flexible pipe and reception bandwidth finally return under the default configuration.
