Basic knowledge and product introduction of modular Switches

Modular switches are still commonly used. So I have studied the basic knowledge and products of modular switches. I will share them with you here, hoping they will be useful to you. When talking about modular switches, we should talk about the bandwidth of the backboard. The backboard bandwidth is an important parameter when we talk about the performance metrics of A vswitch. It is the maximum data volume that the vswitch interface processor, interface card, and data bus can handle.

The bandwidth indicates the total data exchange capability of a vswitch. The higher the bandwidth of A vswitch, the stronger the data processing capability, but the higher the design cost. The bandwidth of a backboard is generally a modular switch. It determines the maximum connection bandwidth between each template and the switching engine. The fixed port switch does not actually have the concept of Backboard bandwidth. For vswitches with fixed ports, the exchange engine and the Network Interface Template are integrated. Therefore, the forwarding performance parameter provided by the manufacturer is the forwarding performance of the exchange engine. In view of the advantages of modular switches in modern networks. Modular switches are of course the first choice for building networks. The following describes several vswitches from the modular perspective. For your reference.

Cisco Catalyst 4000 Series network switches

The Catalyst 4000 Series provides powerful fundamental architecture advantages. Relying on the centralized shared memory structure, all boards can be easily and economically upgraded to higher-level network functions, avoiding the common complete upgrades in stacked products. By supporting transparent exchange boards with functions, this structural advantage provides great investment protection capabilities. It can protect the already installed Catalyst 4000 systems and develop to high-level capabilities as technology advances in the future. This makes it even possible for a Catalyst 4000 Switch with a traditional board to simply add more engine modules, such as the new layer-3 service module ), you can easily upgrade all system ports to higher-level switching functions. In particular, you can achieve this without changing your original Board, which is usually the case in other conventional exchange products. In addition, the investment protection capability is further improved by extending the time your Catalyst investment is used.

The Catalyst 4000 cabinet provides:

◆ Modular cabinets with three slots, one of which is reserved for the switch engine and two for the switch Module

◆ Two power supply racks that support redundancy (optional), load balancing, and fault tolerance AC Power Supply

◆ One hot-swappable fan bracket. Single IP Address Management Program

◆ Port, power supply, and link Redundancy

In the future, the wiring room requirements will be extended, including wired and wireless PC connections, IP Phone devices and gateways, and multi-point Transfer Stream applications (such as IPTV) layer-7 services, Gigabit desktop network connections, and 10 GB backbone network connections. The advantage of configuration flexibility and modularization is that Catalyst 4003 provides a comprehensive and scalable 10/100/MBT Ethernet switch module. These modules currently provide enterprise network intelligence that can be hot swappable and plug-and-play, and can be flexibly expanded to meet the increasing network needs in the future.

Cisco Catalyst 6500 Series Modular multi-layer switch

It is also a modular switch launched by Cisco Systems, a global network equipment leader. It can be called the previous top-level switch. He has won many "industry first" titles. Cisco's next-generation Catalyst 6500 series module and switch Engine Supervisor Engine 720 contains Cisco's 11 new application-specific integrated circuit ASIC), which not only expands Cisco's leading position in the network field, it also provides unparalleled investment protection.

Cisco Catalyst 6500 Series Modular multi-layer switches include four network security service modules: "Catalyst 6500 Firewall Service Module", "IPSec Virtual Private Network Service Module", "SSL Service Module", and "advanced network analysis module ", its advanced technology is the same as that of Cisco PIX Firewall and Cisco Virtual Private Network products. It can be applied to security services around the network and a variety of network services from Layer 2 to Layer 7, fully integrated with Cisco Catalyst 6500 series switches, and integrated with security services and multiple IP services without compromising network performance, such as VoIP, wireless local area network integration, service quality (QoS), and content exchange technology, and can be easily used with Cisco voice, video and data integration architecture (AVVID) in the network security (SAFE) the solution is the same.

Comments:

As a high-end modular switch. The strong flexibility and scalability are certainly the advantages of it and also have a very high cost-effectiveness. IT can adapt to future development and protect the architecture of investment-supporting three generations of interchangeable and hot swappable modules in the same chassis to improve IT infrastructure utilization and increase investment return, and reduce the total cost of ownership. It is applicable to the port density and interface types required for the cabling room, enterprise core layer, and distribution layer of large key businesses. It provides high-speed Wan, ATM, and SONET interfaces compatible with other core routers. Therefore, Wan convergence and Management of campus network and Metro connections can be implemented on a single platform.
