Embodiment Construction

[0037] RPR loop formation and service configuration:

[0038] Figure 2 is a schematic diagram of RPR networking. A typical loop formation diagram of an RPR loop is shown in the figure: Site S1 (site MAC address is 0x000000000001), S2 (site MAC address is 0x000000000002), S3 (site MAC address is 0x000000000003), and S4 (site MAC address is 0x000000000004) A 1.25G closed loop, the service is communicated between site S1 and site S3. Site S1 is configured with a reserved bandwidth of 200M and a limited bandwidth of 300M, and site S3 is also configured with a reserved bandwidth of 200M and a limited bandwidth of 300M. .

Abstract

The invention discloses a realizing method of dynamic display elastic grouping looped topological network, which comprises the following steps: 1. affirming the network topological information of the dynamic display topological network; 2. transmitting and exchanging the topological information; 3. obtaining the topological information through net management; establishing the topological graph according to the topological information; 4. proceeding real-time updating for the topological graph according to the change of topological information. The invention adopts the checked joint as datum point to display the present topology of entire loop dynamically, which updates the topological graph automatically when the protective switching affair occurs.

Description

technical field [0001] The invention relates to the elastic packet ring technology, in particular to a method for dynamically displaying the network topology of the elastic packet ring. Background technique [0002] Resilient Packet Ring (RPR: Resilient Packet Ring) technology, as the IEEE802.17 standard, implements bandwidth sharing and protection with a dual-ring structure. RPR has the following characteristics: [0003] 1. High bandwidth utilization; [0004] 2. Use a fair algorithm to guarantee Qos (quality of service guarantee). [0005] 3. Provide fast protection less than 50ms. [0006] Figure 2 shows a typical networking application of RPR technology. Four sites form an RPR ring. The RPR ring obtains the network topology and implements service protection through the topology discovery and protection protocol. Topology discovery is a periodic process. Each site periodically broadcasts its capability information to the entire ring with TP frames and ATD frames, and...
