Smart Ethernet switches also require diversified development

Intelligent Ethernet switches are still commonly used. So I have studied the future development direction of the intelligent Ethernet switch. I would like to share this with you and hope it will be useful to you. The future development of Ethernet technology is centered on applications. Therefore, the diversity of applications requires more and more intelligence for network products. The development of intelligent Ethernet switch products continues to follow the three major development directions of speed, intelligent application and coverage, which also promotes the extension of intelligence from the core of the network to the edge.

In the past, the network was mainly used for connection. The network mainly adopted the smart products currently mentioned at the core, while the "silly" product series at the edge. Now, with the development of technology, the scale of user networks is getting bigger and bigger, and network applications are getting more and more complex. With the popularization of 1 Gbit/s, the bandwidth for edge access is getting wider and wider, intelligent Network applications began to spread from the core to the edge, with smart products at the core and edge, forming the current intelligent exchange system.

The multicast service has become one of the main services of the IP network. The traditional multicast service cannot control the access permissions of subordinate users. Intelligent Ethernet switches should be able to provide control over multicast service permissions. Only Authenticated Users can receive corresponding multicast services. This concept is called controllable multicast or controlled multicast. The access layer supports ACL based on complex stream classification. It can be based on the user's source mac, destination mac, source physical port number, destination physical port number, source IP address, destination IP address, source CIDR block address, destination CIDR block address, and layer-4 protocol socket) data Services are classified by user-defined rules, and different service quality or ACL control are provided for different business flows according to the preceding classification, that is, forwarding of a specific stream is prohibited or allowed.

As a smart Ethernet switch, in addition to managing users, it should also have strong management and security features for devices. First, the management of devices should work with the management of network management devices. SNMPV1/V2/V3, RMON1, 2, 3, 9, and WEB network management should be supported, provides visualized and convenient device management from the network management platform. In addition, the device itself should have certain security features, including L2 port bundling, STP/RSTP, MSTP, L3 VRRP and other link backup or device backup functions. Then, whether the smart Ethernet switch supports smooth network upgrade, whether the management operations of multiple devices are easy to understand during network expansion, and whether it supports on-demand business and performance expansion.

Currently, the smart Ethernet switch also provides 802.1x port authentication and other security control functions, and achieves linkage with network security systems such as firewalls and IDS on the Smart Ethernet switch, in this way, the vswitch is upgraded from a pure network connection level to a full-network security system level, and user management, billing, and other operation functions can be implemented based on the user authentication mechanism. The following describes several smart Ethernet switches. Because it focuses on the intelligence of switches, the performance, application location, and price of several smart Ethernet switches introduced below are quite different.

Cisco ciscoft-st3750 series switches

Ciscoft-st3750 series switches are an innovative product launched by Cisco. They combine ease of use and redundancy to improve the efficiency of stacked switches in the LAN. This product series uses Cisco StackWise technology, which not only achieves 32 Gbps stack interconnection, but also physically and logically enables the integration of several independent Switches during stacking, this facilitates the establishment of a unified and highly flexible exchange system. For medium-sized organizations and enterprise branches, the Catalyst3750 series can automatically configure intelligent network services by providing configuration flexibility, supporting the converged network mode, and reducing the difficulty of deploying integrated applications, to adapt to changing business needs.

Edit opinion:

The Catalyst3750 series is specially optimized for high-density Gigabit Ethernet deployment, including a variety of switches that can meet the access, aggregation, or small network backbone network connection requirements. At the same time, ipvst3750 supports IPv6, but it needs to be upgraded to start later. Ipvst3750 can achieve maximum performance through hardware-based IPv6 routing.

Huawei 3ComQuidwayS3952P-EI

S3952P-EI is a new generation of intelligent Ethernet switch product launched by Huawei 3Com to design and build high elastic and intelligent network. It uses IRF technology and can form a unified exchange matrix of multiple scattered devices. It is suitable for office network and service network aggregation and access layer switches. The S3952P-EI has a switching capacity of 19.2 Gbit/s, supports all port line rate Forwarding (packet forwarding rate reaches 13.2 Mpps), supports up to 4 K compliant with the IEEE 802.1Q standard VLAN and 32 port convergence. It provides four Gigabit Ethernet ports, effectively solving the need for simultaneous access to gigabit servers over multiple Gigabit Links on a single device.

As a layer-3 intelligent Ethernet switch, S3952P-EI also supports centralized MAC address authentication and 802.1x authentication, DUD authentication. It supports hierarchical user management and password protection to effectively prevent unauthorized users from accessing the network. It supports QoSProfile and dynamically provides pre-configured QoS functions for authenticated users. It supports SSH features, even if a user remotely logs on to an Ethernet switch through a network environment that cannot guarantee security, the switch can be protected from attacks such as IP address fraud and plaintext password interception.

Edit opinion:

S3952P-EI is an enhanced product in the 3900 series, supporting all IRF functions (Distributed device management, distributed redundant routing and Distributed Link aggregation), there is a perfect strategy for QoS and reliability assurance. In the intelligent Ethernet switch products less than 20 thousand yuan, the performance of the S3952P-EI is class.
