Performance-10 Gigabit network bandwidth expansion

10-Gigabit network applications should not only increase network bandwidth, but should provide users with better and higher network performance and business application characteristics, so that 10 Gigabit investment is worth the money.

With the increasing popularity of 10g products and technologies
Mature, the price threshold restricting the wide application of 10 Gigabit products has made a major breakthrough. At the same time, 10-Gigabit applications are being expanded to the network aggregation layer, laying a solid foundation for the popularization of 10-Gigabit applications. From a rational point of view, we should explore the real value that 10-gb gives to users.

Build next-generation smart networks

Today, users' network needs have been transformed from initial pursuit of simple physical connections to multi-service applications including data, voice and video. The challenge facing users is how to better solve network expansion, increase of branches, and how to ensure network security and better achieve network management, in this way, a next-generation Intelligent Network with uninterrupted communication is built to provide users with high performance, high scalability, and the highest level of redundancy protection in integrated applications.

High port density. The first application of 10-Gigabit products must be at the core backbone layer of the network. As the core layer equipment of the network backbone, the port density design will become an important indicator for measuring 10-Gigabit products. It not only needs to provide multiple pure 10g ports, but also must provide support for the original Gigabit ports in the user network from the perspective of Protection Investment, and support for the emerging 40 GB and GB Ethernet standards in the future.

Smooth upgrade. Protecting existing investment, modular design, and on-demand network upgrade are important measures for users to select an overall network solution. The user puts forward backward compatibility requirements for network equipment providers in terms of the system design of 10 Gigabit products, and all old line cards can work normally in the upgraded system. Therefore, in the future capacity upgrade process, 10-gb products must be smoothly upgraded without interrupting network services.

High Security and QoS Assurance. QoS Assurance mechanisms are essential for network operation. The security and QoS mechanisms provided by 10-Gigabit products include: support for smooth burst and network traffic load balancing; Make full use of bandwidth, reduces the packet loss rate in the case of congestion, distinguishes the user priority, distinguishes latency-sensitive, jitter-sensitive, and loss-sensitive business flows for different processing, and controls the data flow or port traffic; supports real-time traffic viewing and long-term traffic statistics, provides a comprehensive understanding of device traffic, and uses ACL access control and various security measures to intelligently identify malicious attacks and dynamically control access, attackers are cut off before they interrupt the network.

Flexible service processing capabilities. The 10-gb product must provide users with a high-performance, large-capacity, multi-business, and cost-controllable solution, at the same time, we also fully consider the diversity of user networks and business in the design process of the system architecture.

10g to edge Scaling

Mark Steggert, School of information at the University of Pittsburgh, said, "As the client speed continues to increase, users will eventually make the cluster's Gigabit link saturated, and they can have multiple clusters with 10g links, it will be our future development direction."

Due to product technical maturity and price considerations, new products and technologies are generally not selected in one step. users usually adopt a way to build core backbone networks using new products and technologies, this is also true for 10-Gigabit technology.

Although the current 10g backbone, Gigabit to desktop has become a mainstream. However, we also see that due to the uneven development of informatization, the network infrastructure construction of a large part of users is still on the basis of 10 or 100 MB. There are a lot of questions about whether a user's network is upgraded to 10-gb by upgrading to the backbone core layer, the aggregation layer to gigabit, or directly upgrading to 10-gb. Abner Germanow, an analyst at the IDC, said, "there is still a long period of time before the 10 Gigabit network significantly reshapes the LAN design approach, and a considerable number of people are still working hard to implement the gigabit network in the wiring room ." He believes that directly upgrading from the wiring room to the trunk to 10 Gigabit can eliminate a network layer, thus reducing network complexity.

In response to users' application requirements and the current 10g product provided by the device provider is primarily a core backbone layer device, Extreme is targeted at gigabit-to-Desktop Users facing connection bottlenecks, launched the 10G switch product Summit 400. In addition to 48 10/100/Mbps ports, this product also provides two slots for installing a 10-Gigabit Ethernet transceiver. This product can be used as a high-end workgroup switch for users or as a convergence layer switch to connect the wiring room to the Gigabit trunk, this provides an end-to-end 10 Gigabit overall solution. Varun Nagaraj, vice president of Extreme product management, said that because no intermediate layer switch is required, the number of devices running is reduced to reduce management and operation costs.

Enjoy the bandwidth anytime, anywhere. Extreme provides an end-to-end 10g solution and policy-based Ethernet QoS functions including bandwidth management, business shaping, and business classification, it ensures the business and performance of the network, enables both the enterprise network and the man network supplier to achieve the same performance, and provides users with a 10g exchange solution that can break through any bottleneck.

Smart bandwidth management. It ensures precise control of the latency of each group stream. Policy-based QoS eliminates latency errors when the WAN and VLAN are extended to a long distance.

Business shaping. Extreme-specific business shaping tools can prevent burst bandwidth-intensive services and applications from causing system crashes. More importantly, a group that exceeds the threshold is buffered until enough throughput is provided to send the group safely, and any service or application that needs it can use its idle capacity. In a 10-Gigabit network, if the bandwidth is not used, it is a waste.

Business type. The 10-gb product provides a comprehensive classification function for eight queues on each data port. The classification can be express Classification Based on DiffServ and IEEE 802.1p tags, or implied classification, based on the entry port, IP source address, and destination address, the layer-4 Application port or MAC address of the IP address. For strict QoS deployment, it is equally important that this classification technology can easily process these in-depth classifications even when Layer 2 switching is executed.

By focusing on features unrelated to bandwidth, such as fault tolerance, security, and scalability, Extreme completely reshapes the entire network from the edge to the backbone, the next generation smart network with both business and performance is successfully built.
