Application viewpoint: Role of vro Technology in Network Development

With the development of China's communication industry, vro technology is widely used. So I have studied the role of vro technology in the development of the network. Here I will share it with you, I hope it will be useful to you. With the rapid development of network applications, especially video and voice applications, the Data Types of voice, video, and other large data volumes must be frequently transmitted over a converged network, applications such as IP phones, video conferences, and large-capacity database groups are accelerating the demand for bandwidth. 10G Ethernet 10GE) technology, provides a simple way to upgrade bandwidth, to solve the problem of increasing bandwidth. From a technical point of view, the user's demand for 10 Gigabit is also very obvious. From the perspective of the overall network architecture development, 10 Gb is a symbolic technical platform.

With the rapid growth of enterprise and campus network applications, the multimedia network teaching and digital library applications in colleges and universities are constantly expanding, and the backbone networks of enterprises and campuses are under constant upgrade pressure, from the original Fast Ethernet to the current gigabit network, the network will soon be transitioned to a 10-Gigabit network. The 10GE high-speed link will be used to build backbone links of the campus network and Enterprise Network and the connections between branches and the headquarters, this service enables end-to-end Ethernet Access and improves transmission efficiency to provide users with services such as multimedia services, data stream content, and SAN. The 10-Gigabit Ethernet router technology provides features such as high bandwidth, low latency, and easy network management. It is suitable for enterprise and campus backbone network construction.

10 Gigabit enterprise router Products

There are also many manufacturers that can produce 10 Gigabit enterprise router technology. The following describes four products: Force10, Cisco, Huawei, and harbor.

1. Force10's eseries 10-Gigabit exchange router technology

The Force 10 series E1200/E600/E300 provides a standard for the next generation high-performance switching router technology. Within one machine, it can provide 672 Gbps wire speed ports and 56 10 Gbps wire speed ports, even when the ACL is enabled, the line rate forwarding performance of each port can be guaranteed. At the same time, the eseries products can provide comprehensive layer-2 switching and layer-3 routing functions. This new product can be used in Server Clusters, grid computing, Campus Backbone Networks, next-generation interconnection centers, Metro Ethernet, and other places. Each slot of Force 10's e-series products can provide a throughput of Gbps. It enables the line rate forwarding performance when advanced business features are enabled, and determines the low latency and jitter, robust and complete layer-2 switching, layer-3 routing, and flexible defense against DoS attacks are all necessary functions on the Internet. Based on its powerful and low-cost EtherScale architecture, Force 10's e-Series Products set industry standards for flexibility and high performance.

Force10 is a leading manufacturer of high-performance 10-Gigabit and 1-gigabit Ethernet route switches. Force10 eseries is the industry's first product to provide real-line-rate 10-Gigabit Ethernet route and switch. Force10 eseries route switches provide the best flexibility in the industry, unparalleled scalability, and line rate forwarding performance. Based on the patented completely distributed hardware and modular software architecture, the eseries routing switches provide predictable application performance, increase network availability, and reduce operating costs.

2. Cisco 10-Gigabit router technology

Cisco CRS-1 uses the Cisco ios xr software, a unique self-recovery duplex self-defense operating system that enables uninterrupted operation and extends system capacity to 92 Tbps. Cisco CRS-1 consists of two components: line card rack and switch matrix rack. Their combination enables Cisco CRS-1 to expand from 16 40 Gbps slots to 1152 40 Gbps slots-distributed in 72 Line Card racks interconnected through 8 matrix racks. All these components work in the same system.

The Cisco CRS-1 single-rack system includes a single 16-socket line card rack with a total switching capacity of 1.2 Tbps. The line card rack is built through a line card chassis designed with an intermediate backplane. The Cisco CRS-1 multi-rack system consists of 2 to 72 16 slots of Line Card racks and 1 to 8 Switching Matrix racks with a total switching capacity of up to 92 Tbps. The line card rack is only connected to the switching matrix card rack. Level 2 of Level 3 Exchange is conducted here. The NE5000E achieves capacity expansion through optical backplane interconnection and supports cascade of multiple frames. The interface capacity can be expanded to 80 Tbps, and 4096 10g pos/10GE line speed interfaces are provided, you can also provide 1024 40 Gb POS interfaces for wire speed. All key hardware components provide redundant backup, and feature state-based hot switching and uninterrupted forwarding at the operation level. All components have hot swapping functions, adopt passive Backplane Design, and provide hot Patching Technology, implements smooth software upgrade and provides protection mechanisms such as IP/MPLS fast rerunning, virtual routing redundancy protocol VRRP, and RPR self-healing Ring Network (IPS) to effectively ensure high reliability of network operation, 99.999% of system availability can be achieved.

Quidway NetEngine 5000E core router technology is a top-level core router product launched by Huawei for backbone Internet nodes, man core nodes, and Data Interconnection center nodes. Adhering to the fifth-generation router technology concept, NE5000E adopts distributed and scalable design based on advanced network processor technology, ASIC Technology, IPv6 technology, and optical backplane interconnection technology, and features massive exchange capacity and ultra-high forwarding performance, it fully meets the needs of the next generation Internet for bandwidth performance, service quality, and service provision. NE5000E is an ideal choice for the next generation of Internet because of its high performance, rich business features, high reliability, and modular scalability.
