Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of Internet protocol (Internet Protocol, abbreviations
IP) service bandwidth determines method and the network equipment in network.
Background technique
In IP network framework as shown in Figure 1, in addition to carrying Generation Mobile Telecommunication System (2nd Generation, abbreviation
2G), 3G (Third Generation) Moblie (3rd Generation, abbreviation 3G), forth generation mobile communication (4rd Generation, abbreviation:
4G) outside the business such as network, WLAN (Wireless Local Area Networks, abbreviation WLAN) and broadband upstream,
The business such as enterprise's special line are also carried, the bandwidth resources of IP network are competed between each business, to guarantee that business can be run.
In order to guarantee the transmission quality of business, there is the solution that following two is traditional:
The first: the bandwidth ability by expanding each node in IP network guarantees that each business occupies enough bandwidth, the party
Case will cause the reduction of network overall bandwidth utilization rate, and network construction cost is excessively high.
Second, different Business Streams is distinguished in bearer network, and different bandwidth allocations is provided for different Business Streams
Mechanism, the different grades of service and different forwarding strategies are controlled by the fine-grained management to Business Stream, are improved end-to-end
Network bandwidth utilization factor.
In second of solution, IP network is needed to provide business end to end from access ring, convergence ring to core ring
Bandwidth guaranteed, main method are that different business is carried using different tunnels (Tunnel), are held end to end for tunnel configuration
Promise information rate (Committed Information Rate, abbreviation CIR) bandwidth.
When to 2G, 3G, 4G and enterprise's private line service configuration CIR bandwidth, according to access ring, the level of convergence ring and core ring
With the CIR bandwidth of 1:1:1 configured tunneling technique, such as 2G business is 3M, 3G in the CIR bandwidth of access ring, convergence ring and core ring
Business is 30M in the CIR bandwidth of access ring, convergence ring and core ring, and 4G business is in access ring, convergence ring and core ring
CIR bandwidth is 80M, the band width configuration access ring that enterprise's private line service is bought according to client, the CIR band for converging ring and core ring
It is wide.
Also, the reserved bandwidth of each network port is configured according to the convergence ratio of 4G, it is assumed that network port physics in access ring
The 50% of bandwidth is used as reserved bandwidth, converges 67% of network port band width in physical in ring and is used as reserved bandwidth, net in core ring
The 100% of network ports physical bandwidth is used as reserved bandwidth.
Assuming that the CIR bandwidth of new business is indicated with B1, the reserved bandwidth of the network port indicates that the network port is with B
The sum of CIR bandwidth for the business being configured indicates with B2, then when meeting relationship: when B1≤B-B2, then it represents that the network port can
Band width in physical can satisfy the demand of the new business, and otherwise, then available band width in physical cannot expire in the network port
The demand of the foot new business.
Second of solution is suitable for carrying the scene of single business, if the end in access ring, convergence ring and core ring
Mouthpiece carrier has the business of different convergence attributes, and access ring, convergence ring and core ring configure the CIR band of each business according to 1:1:1
Width, and plan according to the convergence ratio of 4G business the reserved bandwidth of each business, it is low to may result in each network port bandwidth availability ratio.
Assuming that the 50% of network port band width in physical be used as reserved bandwidth in access ring, converge 67% of the network port in ring be used as it is reserved
Bandwidth, then the bandwidth availability ratio of access ring and convergence ring is lower；Assuming that the 100% of the network port being used as reserved band in access ring
Width needs to improve the band width in physical of the network port in convergence ring and core ring when planning, it will causes in convergence ring and core ring
The waste of network port bandwidth resources.
