Memory Usage Analysis of H3C SR6600 series routers

When using the H3C SR600 series routers, some netizens may find that as long as the routers start up, the memory usage increases sharply and exceeds 50%. This is a normal phenomenon or a problem with the routers. Today, I will explain why this problem occurs. The memory occupied by H3C SR600 series routers during startup mainly includes the memory occupied by features, the support module, and the memory occupied by forwarding.
1. Most features require a certain amount of memory during runtime. This part of memory is usually allocated at system startup or when features are enabled, allocate enough memory to ensure that the feature does not need to dynamically apply for memory frequently during usage. The amount of memory occupied by the feature depends on the number of features configured. Www.2cto.com 2. Part of the memory occupied by the support module is used to support basic system task scheduling, management, human-computer interaction, system configuration, and other functions, the minimum memory required by the computer operating system is the same. 3. the forwarding function of the H3C router is the core function of the router. Therefore, sufficient memory must be allocated in advance to ensure high-performance and large-capacity forwarding. Generally, MB of memory is allocated at startup and about 50 MB of memory is used. The memory used for forwarding is called from the MB of memory allocated at startup, instead of occupying dynamic memory, the memory is dynamically allocated only when the required memory exceeds the initial MB when changes occur during the forwarding process, such as session establishment, route changes, and user launch. To sum up, it is normal that the memory usage of H3C SR600 series routers exceeds 50% after startup. The maximum memory occupied by the system varies with the product specifications, as long as the Running Load of the vro does not exceed the requirements of the Product Specification, there will be no insufficient memory. Generally, the memory needs to be increased only when the memory usage exceeds 90% during system operation. This article is from
