Measure the test taker's understanding about the comprehensive performance of 10-Gigabit core route switches.

With the development of China's exchange industry, various switches have been updated and upgraded. Here we analyze the comprehensive performance and Practical Application of 10G core route switch, quidway S8500 series 10-Gigabit core route switch (S8500) is a new generation of high-performance core route switch developed by. It provides high-capacity, high-density, and modular layer-4 line rate forwarding performance, powerful IP routing performance.

It also supports distributed MPLS line rate forwarding, comprehensive QoS Assurance, effective security management mechanisms, and highly reliable telecom-level design, to meet the needs of high-end users for multi-service, high reliability, large capacity, and modularization, it can be widely used to build backbone networks, exchange cores, and aggregation centers for IP Man and large-scale campus networks.

Advanced Architecture

The S8500 series products adopt a fully distributed architecture and use the longest route matching and Crossbar technology to exchange high-speed packets. This greatly improves the forwarding performance and scalability of the 10-ge core route switch. The Crossbar Switching Network works in load balancing mode, and the S8512 can provide a switching capacity of up to Gbps. The interface board connects multiple high-speed buses to the Crossbar exchange network on the two main control boards respectively, so as to realize real hot backup of Dual-master and dual-exchange networks, greatly improving the system reliability.

The S8500 series products adopt the longest matching and packet-by-packet forwarding method. With the continuous improvement of the design level and the increase of technology and integration, S8500 can achieve the longest matching of line speed based on the existing low cost, the hardware of the traditional 10-Gigabit core route switch can only process the exact matching table, and the longest matching table can only be processed by software, so as to maintain the line speed performance and low cost, the revolutionary solution solves the defects of traditional switches. It can effectively combat network attacks such as "Red code" and "Shock Wave", and is more suitable for large-scale, multi-business, and complex traffic access networks, it is more suitable for the development of Metro Ethernet.

Large capacity, high density wire speed switching

S8500 series products have powerful hardware platform upgrade capabilities. A large number of bus interfaces are reserved on the Backplane for subsequent expansion. S8500 series provide Gbps switching capacity and mpps packet forwarding capability, it can be smoothly upgraded to 1.44Tbps switching capacity and supports various high-density business boards. The entire machine can support up to 576 Gigabit ports and 0.48 million Gigabit ports, meeting the requirements of large capacity and high port density of core layer equipment, it can meet the increasing bandwidth needs of users and greatly protect and save user investment.

Supports flexible QinQ features

Supports the flexible QinQ feature (Selected QinQ). You can choose whether to play the outer VLAN tag and the outer VLAN tag Based on the stream classification results, you can implement flexible QinQ features based on rules such as Vlan tag, MAC address, IP protocol, source address, Destination Address, priority, or application port number. The preceding stream classification method can be used to encapsulate outer VLAN tags of packets based on different users, services, and priorities, so as to provide good support for multiple businesses.

Support for operation-level 10GE Interfaces

The operation-level 10GE interfaces provided by the S8500 series overcome many limitations of the early 10GE interfaces, and provide powerful QoS Assurance Based on online speed forwarding, it also supports rich features such as ACL, Policy Routing, and security. In addition to standard LAN interfaces, S8500 series products also provide 10GBASE-LX4 interfaces using wavelength division multiplexing technology, which greatly improves the flexibility of the user group network. The 10GE interfaces of the S8500 series provide powerful service processing capabilities while maintaining the consistent compatibility and ease of use of Ethernet and convenient upgrade.

MPLS distributed line rate support

The S8500 series supports all-round mpls vpn services, including L3 mpls vpn, VPLS, VLL, MCE, and HoPE. The S8500 series products follow the design philosophy of both business and performance. On the one hand, the increase in bandwidth and network scale will promote the performance and capacity of the 10-Gigabit core route switch. On the other hand, the business development requires the 10-Gigabit core route switch to be more intelligent and provide stronger business capabilities. S8500 series products Implement MPLS distributed line rate forwarding to meet the needs of high-end users for new value-added services.

Carrier-Level Reliability Design

The S8500 series products adopt a distributed structure and support dual-master switching board and passive Backplane Design. All boards support hot swapping. The power supply system adopts 1 + 1 redundant hot backup and supports dual-circuit power input; fan Redundancy Design and automatic speed control are supported. STP, RSTP, MSTP, RPR, and VRRP protocols are supported to meet the demanding telecom-grade network reliability requirements. The system reliability reaches: 99.999%.

Comprehensive Security Mechanism

S8500 products support OSPF, RIP v2, and BGP v4 message plaintext and MD5 ciphertext authentication. 802.1x authentication is used to authenticate access users. It supports Secure SNMPv3 network management protocols and configuration security, users of different levels have different configuration permissions. Two user authentication methods are provided: local authentication and RADIUS Authentication.

The S8500 series products adopt a fully distributed architecture and use the longest route matching and Crossbar technology to exchange high-speed packets. This greatly improves the forwarding performance and scalability of the 10-ge core route switch. The Crossbar Switching Network works in load balancing mode, and the S8512 can provide a switching capacity of up to Gbps. The interface board connects multiple high-speed buses to the Crossbar exchange network on the two main control boards respectively, so as to realize real hot backup of Dual-master and dual-exchange networks, greatly improving the system reliability.
