Gigabit network switch structure and dynamic editing technology

It should be said that gigabit network switches have become the first choice for medium and large enterprises. A high-performance switch not only improves the speed of devices, but also adds a lot of functions. The new intelligence of GE switches makes Ge switches an indispensable choice. The following describes the structure of a gigabit network switch. In fact, we can also see some new smart aspects. After integration, everything is very simple.

New intelligence of Gigabit Switches

GE switches are essential to the networks of large and medium-sized enterprises. With the advent of GE Ethernet technology, the structure and performance of GE switches have also greatly changed. Currently, high-performance switches not only greatly improve the switching speed, but also add some routing functions. Some Gigabit network switches also add the functions of the network security firewall, the network management software interface is also more intuitive.

Gigabit network switch structure

This section describes the technical structure of an integrated network service exchange. This structure provides a basic new method to reduce the management burden, improve the distributed computing response, and control the network infrastructure required for Internet-centric applications.

Discrete management, control, and data plane

Integrates the gigabit network switch structure of the network service. All data pre-transmission tasks are completed at line speed using the high-speed customized ASIC module. Data Pre-transfer tasks are divided into control and management tasks. The control and management tasks are subdivided into time-dependent and non-time-based tasks. In the matrix of a distributed RISC processor, lightweight processing processes all execute Time-Dependent Tasks.

Many distributed services can be accessed through integrated programmable hardware, such as directory service, authentication service, Firewall Service, Address Allocation service, and location service. All necessary information used to control network applications can be provided to ge switches in this way. Therefore, GE switches do not require any additional protocols or supplementary services.

Dynamic switch Editor/switch control distributor

Currently, some gigabit network switches do not use a closed operating system, but use an open network operating system, such as WindowsNT, this provides a convenient and open public software platform for advanced management, security, naming, and integration through asynchronous computing environment transmission. It facilitates network administrators to operate and manage the system.

The dynamic switching editor is responsible for controlling, managing, and service information from WindowsNT dynamic assembly to specific hardware commands. These commands are downloaded to the switch control distributor, where they can be issued to the forward pass or policy filter table of the switch ASIC. The switching ASIC is responsible for all the packet forwarding tasks in the gigabit network switch. The processing tasks of multiple packets are completed in parallel by the ASIC. This includes stateful-driven application traffic classification and L2/L3 forward transmission. No additional operations are performed to process data packets for L2, L3, and L4 of the OSI stack.

Provides ATM options

Currently, most of the public WAN backbone networks are ATM networks. Ethernet networks must be seamlessly connected to the ATM Backbone Networks, and gigabit network switches must provide ATM integration options. Taking Fore's ESX switch as an example, it uses the unique "Application-related" exchange capability ing application technology to provide intra-domain services to ATM, so as to truly exert the strength of Multi-Service ATM core.

The ESX gigabit network switch can provide high-quality transmission for composite applications in multimedia stream, voice, frame, and meta-hybrid environments, and the implementation of data transmission does not require any changes to the application itself. You only need to select the ATMOC-12c interface, the corresponding ATM connection protocol can be supported.
