Intelligent connection based on SRv6
* SRv6 is a future-oriented new-generation protocol, which naturally supports IPv6 and meets the needs of mass address space access. SRv6 identifies applications and tenants, enabling intelligent uplink selection, such as delay and bandwidth, to ensure SLA. At the same time, SRv6 implements a unified protocol and simplifies the configuration.
* SRv6 uses 128bit Segment to define network functions. Then, a series of forwarding and processing behaviors of network devices can be realized by arranging the Segment, so as to complete business orchestration. Compared with MPLS SR, the protocol has better scalability and compatibility with the SDN controller. It is more suitable for deployment in DCI and MAN scenarios.
* The notable feature of SRv6 is that the forwarding surface uses IPV6, and it is easier to realize the interconnection of different networks based on IPV6 reachabability. In the domain, SRV6 mode is used for forwarding, while in the interdomain, it is only necessary to use common IPV6 forwarding. There is no need to convert MPLS into IP and do a large number of complex configurations.
Build flexible Ethernet based on FlexE technology
* As a technical architecture based on Ethernet and industrial chain expansion, FlexE technology fully reuses existing IEEE 802.3 Ethernet physical layer standards, lightweight enhancements at MAC/PCS logic layer, flexible multi-rate interface, and seamless connection with IP technology. In the IP/Ethernet technology system to better meet the needs of large bandwidth, flexible speed and channel isolation, in line with the development trend of technology and industry. The rise of video, 5G and other businesses, as well as the improvement of FlexE technology and enhanced functions, are accelerating the formation of FlexE industry chain.
* Based on FlexE, 5G network segmentation can be realized to meet the bearer requirements of different services through the segmentation of network resources and ensure the SLA of services (such as bandwidth and delay). Different services (such as eMBB enhanced bandwidth, automatic driving, uRLLC and mass IOT interconnection) can be hosted in the same IP network.
* Based on FlexE, hard pipeline special lines for key customers can be realized, and hard pipeline technology can be adopted in IP network. For the bearer of important special lines and low-delay sensitive services, end-to-end rigid pipelines can be constructed through FlexE channel function. In statistically reusable IP networks, this end-to-end FlexE hardpipe line can provide quality of service for specific high-value customer services while taking full advantage of the existing network infrastructure.
* Flexible networking of IP+Optical is implemented by FlexE. FlexE, as the UNI interface between router and optical transmission network devices, can match the actual data flow bandwidth carried by UNI interface with the bandwidth carried by NNI interface and WDM link of optical transmission network by rate matching. This greatly simplifies the mapping of the router's FlexE interface to optical transmission network transmission devices, reducing device complexity, CAPEX and OPEX maintenance costs.
* FlexE Bonding is essentially a "L1 LAG (LinkAggregation)" technology. Based on FlexE bundling technology, a link with a larger bandwidth can be constructed by combining interface rates and bundling based on detailed 64/66B blocks. The problem of unbalanced traffic distribution on multiple links with traditional LAG does not exist, and the bandwidth distribution can be 100% balanced.
High precision time Solution 1588v2
* IEEE 1588v2 is a master/slave synchronization system. During system synchronization, the master clock periodically releases the PTP time synchronization protocol and time information. The slave clock port receives the timestamp information from the master clock port. The frequency and phase that keeps slave time consistent with master time. IEEE1588v2 can realize frequency synchronization and time synchronization at the same time. The accuracy of time transmission mainly depends on the frequency accuracy of two condition counters and the symmetry of the link. Compared with traditional timing technology, IEEE1588v2 has obvious advantages. It adopts bidirectional channel, precision is ns level, low cost, can adapt to different access environment and so on. IEEE1588v2 has become an inevitable trend of development under the background of increasing the requirement of precision.

Maximize the system fault isolation capability and reliability.
Multi-level security protection
* Multi-level protection and security of the control plane. The control plane policy feature of the S12500R manages the packet flow from the data plane (DP) to the control plane (CP) by configuring QoS filtering and rate limiting. This ensures that the S12500R switch can identify and protect important packets and discard invalid packets when attacked by DDoS. Ensure that the control plane maintains normal forwarding and protocol status under attack or heavy traffic.
* Supports massive ACL rules and supports full-speed forwarding. You can perform detailed access control on L2, IPv4, IPv6, and MPLS packets and their field combinations.
* Support hardware level encryption Macsec technology (802.1ae), different from the traditional end-to-end basic application layer protection of soft encryption technology, Macsec by authenticating data source cryptography to protect the management of the bridge network and other data control protocols, protect information integrity and provide reprotection and security services. By confirming the frames sent by this station, the Layer 2 protocol can be protected from attack.
Distributed cache mechanism and refined QoS
* To face the next generation data center burst traffic, the innovative use of "distributed entry cache" technology. Each port can accurately allocate bandwidth and shape traffic for all service flows that flow to the port. The accurate scheduling of the forwarding plane ensures that the Ingress distributed cache is supported, and the cache space distributed on each line card is effectively shared and utilized, providing better caching effect.
* The network application model has been transformed from C/S to B/S model. The transformation of application mode leads to the increase of network burst traffic, and the large cache mechanism has become an urgent demand of network devices. The S12500R supports 1600ms burst traffic per 10 gigabit port. Combined with the distributed inlet caching mechanism, the S12500R meets the high burst traffic requirements of large data centers.
* Single chip supports 8GB cache, line card supports up to 32GB (4*8GB, each chip is independent, cannot be shared).
* The system supports a maximum of 64 KB hardware queues, and supports refined QoS and traffic management. It can accurately allocate different priorities and queues to different users and traffic flows based on requirements, ensuring different bandwidth, service delay, and jitter performance.
Comprehensive maintenance inspection mechanism
* Online status detection mechanism, through the dedicated maintenance engine, can realize the equipment switching network board, backplane communication channel, service communication channel, key chips, memory, etc. If a module is faulty, the fault is reported to the EMS.
* Board isolation: Isolates a board from the forwarding plane and does not participate in forwarding on the forwarding plane. However, the isolated board is still on the control plane and can be managed. You can perform real-time diagnosis and CPLD upgrade on the board without affecting system services.
* Support for Ethernet OAM, providing multiple device-level and network-level fault detection means.

* S12500R series fans adopt efficient PWM speed control fans, supporting stepless speed control. The system automatically collects the temperature of the board, calculates the fan speed control curve based on the actual device condition, and sends the fan speed control command to the fan frame. The system supports fan status monitoring (speed monitoring, fault alarm). Automatic zone speed control based on the ambient temperature and board configuration reduces power consumption and running noise, effectively reduces ambient noise, and prolongs the service life of fans.
* The S12500R series supports automatic detection of internal ports. When a slot is not configured with an interface board or a port is not connected to a cable, the system automatically closes the internal port, saving power consumption.
* The minimum power consumption of a 10G port is less than 3.4W, that of a 40G port is less than 10.4W, that of a 100G port is less than 13.8W, and that of a 400G port is less than 20.3W
