Description
Technical field
The present invention relates to communication technical field, particularly relate to service bandwidth defining method and the network equipment in a kind of Internet protocol (InternetProtocol is called for short IP) network.
Background technology
In IP network framework as shown in Figure 1, except carrying Generation Mobile Telecommunication System (2ndGeneration, be called for short 2G), 3G (Third Generation) Moblie (3rdGeneration, be called for short 3G), forth generation mobile communication (4rdGeneration, abbreviation: 4G) network, WLAN (WirelessLocalAreaNetworks, be called for short WLAN) and the business such as broadband upstream outside, also carry the business such as enterprise's special line, the bandwidth resources of IP network are competed, to ensure that business can be run between each business.
In order to ensure the transmission quality of business, there is the solution that following two is traditional:
The first: is by expanding the bandwidth ability of each node in IP network, it is ensured that each business takies enough bandwidth, and the program can cause network overall bandwidth utilization rate to reduce, and network construction cost is too high.
The second, bearer network is distinguished different Business Streams, there is provided different Bandwidth sharing mechanisms, the different grades of service and different forwarding strategies for different Business Streams, by the fine-grained management of Business Stream is controlled, improve ad-hoc network bandwidth availability ratio.
In this second solution, IP network is needed to provide service bandwidth end to end to ensure from access ring, convergence ring to core ring, the business that main method is different adopts different tunnel (Tunnel) carryings, for tunnel configuration committed information rate end to end (CommittedInformationRate is called for short CIR) bandwidth.
During to 2G, 3G, 4G and enterprise's private line service configuration CIR bandwidth, according to access ring, the level CIR bandwidth with 1:1:1 configured tunneling technique converging ring and core ring, such as 2G business is 3M in the CIR bandwidth of access ring, convergence ring and core ring, 3G business is 30M in the CIR bandwidth of access ring, convergence ring and core ring, 4G business is 80M in the CIR bandwidth of access ring, convergence ring and core ring, the CIR bandwidth of band width configuration access ring, convergence ring and core ring that enterprise's private line service is bought according to client.
And, the reserved bandwidth of each network port is configured according to the convergence ratio of 4G, assuming in access ring that the 50% of network port band width in physical is used as reserved bandwidth, converge in ring the 67% of network port band width in physical and be used as reserved bandwidth, in core ring, the 100% of network port band width in physical is used as reserved bandwidth.
Assume that the CIR bandwidth B1 of new business represents, the reserved bandwidth B of the network port represents, the CIR bandwidth sum B2 of the business that this network port has been configured represents, then when meeting relation: during B1≤B-B2, then represent this network port can band width in physical can meet the demand of this new business, otherwise, then available in this network port band width in physical can not meet the demand of this new business.
The second solution is applicable to carry the scene of single business, if access ring, the port carrying converged in ring and core ring have the business of different convergence attribute, access ring, convergence ring and core ring configure the CIR bandwidth of each business according to 1:1:1, and the reserved bandwidth of each business is planned according to the convergence ratio of 4G business, it is possible to can cause that each network port bandwidth availability ratio is low.Assume in access ring that the 50% of network port band width in physical is used as reserved bandwidth, converge in ring the 67% of the network port and be used as reserved bandwidth, then access ring and to converge the bandwidth availability ratio of ring relatively low；Assume in access ring that the 100% of the network port is used as reserved bandwidth, need during planning to improve and converge the band width in physical of the network port in ring and core ring, it will cause and converge the waste of network port bandwidth resources in ring and core ring.
