汉英对照:
Chinese-English Translation:

汇聚层交换机是多台接入层交换机的汇聚点,能够处理来自接入层设备的所有通信量,并提供到核心层的上行链路,因此汇聚层交换机与接入层交换机比较,需要更高的性能,更少的接口和更高的交换速率。

Convergence layer switch is the convergence point of multiple access layer switches, which can handle all traffic from access layer devices and provide uplink to the core layer. Therefore, compared with access layer switches, convergence layer switches need higher performance, fewer interfaces and higher switching rate.

汇聚层交换机是多台接入层交换机的汇聚点,能够处理来自接入层设备的所有通信量,并提供到核心层的上行链路,因此汇聚层交换机与接入层交换机比较,需要更高的性能,更少的接口和更高的交换速率。

Convergence layer switch is the convergence point of multiple access layer switches, which can handle all traffic from access layer devices and provide uplink to the core layer. Therefore, compared with access layer switches, convergence layer switches need higher performance, fewer interfaces and higher switching rate.

接入交换机一般用于直接连接电脑,汇聚交换机一般用于楼宇间。汇聚相当于一个局部或重要的中转站,接入层目的是允许终端用户连接到网络,因此接入层交换机具有低成本和高端口密度特性。

Access switches are generally used to connect computers directly, while convergence switches are generally used between buildings. Convergence is equivalent to a local or important transfer station. The purpose of access layer is to allow end users to connect to the network. Therefore, access layer switch has the characteristics of low cost and high port density.

接入交换机和汇聚交换机主要在运作层级和性能特质上存在区别。运作层级方面,前者向上获取汇聚交换机的网络接入,向下对接用户终端,后者向上获取核心层设备的网络接入,向下对接接入交换机;性能特质方面,前者接口众多,具备用户认证、管理功能,后者接口少但交换速率更高。

Access switch and convergence switch are different in operation level and performance characteristics. In terms of operation level, the former obtains the network access of the convergence switch upward and connects to the user terminal downward, while the latter obtains the network access of the core layer equipment upward and connects the access switch downward; in terms of performance characteristics, the former has many interfaces with user authentication and management functions, while the latter has fewer interfaces but higher exchange rate.

具体介绍如下:

The details are as follows:

1、层级方面:接入层是网络中直接面向用户连接或访问网络的地方,使用在这层的交换机就是接入交换机;而汇聚层主要用来减轻核心层设备的负荷,起着上传下达的作用,具有实施策略、安全、工作组接入等多种功能,汇聚交换机就是在这里使用;

1. Hierarchy: the access layer is the place in the network that directly faces users to connect or access the network, and the switch used in this layer is the access switch; while the convergence layer is mainly used to reduce the load of the core layer equipment, plays the role of upload and release, with the implementation strategy, security, working group access and other functions, the convergence switch is used here;

2、特性方面:汇聚层交换层是多台接入层交换机的汇聚点,它必须能够处理来自接入层设备的所有通信量,并提供到核心层的上行链路,因此汇聚层交换机与接入层交换机比较,需要更高的性能,更少的接口和更高的交换速率;接入层交换机主要是为接入层的访问提供足够的带宽,并具备地址认证、用户认证等用户管理功能,以及用户信息收集工作。

2. Characteristics: as the convergence point of multiple access layer switches, the convergence layer switch must be able to handle all the traffic from the access layer equipment and provide the uplink to the core layer. Therefore, compared with the access layer switch, the convergence layer switch needs higher performance, fewer interfaces and higher switching rate; the access layer switch is mainly for access to the access layer It can provide enough bandwidth, address authentication, user authentication and other user management functions, as well as user information collection.
