Centralized resource management system and method

Abstract

The invention discloses a centralized resource management system and method, and relates to the technical field of communication network transmission equipment. The management of chip forwarding resource table entries is divided into two levels of hardware resources and service resources for management; a service configuration program dynamically applies for the required service resource table resources from the service resource manager according to needs, and the service resource manager dynamically applies for resource pages from the hardware resource manager according to needs, so the flexible configuration of the resources is achieved. According to the invention, different characteristics of various services on chip forwarding table entry resource configuration are used; the service resource table is configured into the global resource attribute and the single-disk resource attribute, the service configuration program applies for global resources or single-disk resources as required according to the characteristics of the service and the forwarding chip, and the problem of resource waste caused by the fact that all services apply for resources in all line cards in a unified mode is solved.

Description

technical field [0001] The invention relates to the technical field of communication network transmission equipment, in particular to a centralized resource management system and method. Background technique [0002] In the common transmission equipment currently on the market, one or more ASIC or NP chips are usually used as forwarding chips for bearing services. The specifications of the built-in forwarding table in the forwarding chip determine to a certain extent the specifications that the equipment can carry various services. With the advent of the 5G era, IoT technology is gradually becoming popular, the number of user accesses is further increasing, and network usage scenarios are becoming more complex. Operators have higher requirements for the flexibility and specifications of services that must be carried by network equipment. . However, since the development of mainstream ASIC or NP chips in the market, simply increasing the forwarding table capacity through st...

Problems solved by technology

One software version can only support one set of business specifications, and has poor adaptability to different requirements of business specifications in different scenarios

[0005] 2. Rough resource management particles:

However, the traditional resource management solution allocates forwarding entry resources to all line cards at the same time, and cannot allocate resources on demand to certain specific line cards according to the forwarding characteristics of the chip, resulting in waste of resources.

[0007] 3. The efficiency of applying for global resources is low:

[0008] After the device has been running for a long time, the resource usage of different single disks is inconsistent, and the available resources are fragmented, which makes it difficult and inefficient to obtain forwarding tables with the same index ID on all line cards
