Smart Connection Based on SRv6
SRv6 is a future-oriented new-generation protocol. It naturally supports IPv6 and satisfies access to massive address spaces. SRv6 can identify applications and tenants, realize intelligent routing based on index such as delay and bandwidth, and ensure SLA. At the same time, SRv6 implements a unified protocol, which simplifies configuration.
SRv6 uses segments with a length of 128 bits to define network functions, and then by arranging the segments, a series of forwarding and processing behaviors of network devices can be implemented to complete service orchestration. Compared with MPLS SR protocol, it has stronger scalability and better compatibility with SDN controller, which is more conducive to deploying applications in DCI, MAN and other scenarios.
The notable feature of SRv6 is that the forwarding plane adopts IPV6. Based on the reachability of IPV6, it is easier to realize the interconnection of different networks. SRV6 is used for forwarding within a domain, and only ordinary IPV6 forwarding is required between domains. It does not need to be like MPLS which need to convert MPLS to IP and do a lot of complicated configuration.
Application requirements for flexible connectivity
The S12500R series switches support VXLAN (Virtual eXtensible LAN) technology, which is a Layer2 VPN technology based on IP networks and in the form of "MAC in UDP" encapsulation. VXLAN can provide Layer2 interconnection for decentralized physical sites based on existing service provider or enterprise IP networks, and can provide business isolation for different tenants.
S12500R series switches support EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network), EVPN is a Layer2 VPN technology, the control plane uses MP-BGP to advertise EVPN routing information, and the data plane supports the use of VXLAN encapsulation to forward messages.
S12500R series switches support large-capacity ARP/ND, MAC, ACL table entries, which can adapt to the flattening requirements of large data center networks.
S12500R series switches support 400G 120km ZR+ transceiver, which is suitable for DCI connection scenarios, and can partially replace the transmission equipment through the ZR+ module, which is more convenient to manage.
High Precision Time Solution 1588v2
IEEE 1588v2 is a master-slave synchronization system. During the synchronization process of the system, the master clock periodically publishes the PTP time synchronization protocol and time information. The slave clock port receives the timestamp information sent by the master clock port and the system calculates the line time delay and master-slave time difference accordingly, and use this time difference to adjust the local time, so that the slave device time keeps the same frequency and phase as the master device time. IEEE1588v2 can realize frequency synchronization and time synchronization at the same time. The accuracy of time transfer mainly depends on the accuracy of the frequency of the two condition counters and the symmetry of the link. Compared with traditional timing technology, IEEE1588v2 has obvious advantages(It adopts two-way channel and the precision is ns-level. The cost is low and it can adapt to different access environments and so on. ) IEEE1588v2 has become an inevitable trend of development under the background of increasing precision requirement in different industries.
Innovative multi-engine control design
It adopts innovative hardware design and provides powerful control capability and high reliability guarantee for the system through independent control engine, detection engine and maintenance engine.
The independent control engine provides a powerful main control CPU system, which can easily handle various protocol packets and control packets and supports fine control of protocol packets, providing the system with a complete ability to resist protocol packet attacks;
An independent detection engine provides a highly reliable and high-performance FFDR (Fast Fault Detection and Restoration-Fast Fault Detection and Restoration) system for fast fault detection such as BFD. It is linked with the control plane protocol to support fast protection switching and fast convergence, which can realize fast fault detection and ensure uninterrupted services;
Independent maintenance engine, intelligent EMS (Embedded Maintenance Subsystem) CPU system, the CPU system supports intelligent power management, and can support sequential power-on and power-off of boards (reduces the power shock caused by power-on of boards at the same time) , improve equipment life, reduce electromagnetic radiation, reduce system power consumption), equipment online status check.
The independent monitoring engine, completely separated from the service control plane, monitors the working status of the device hardware in real time, including power load and power adjustment, automatic fan speed adjustment and dynamic energy allocation of the whole machine.
Data Center Level Reliability Guarantee
The S12500R series products provide a dedicated FFDR system for fast fault detection such as BFD, and cooperate with the control plane protocol to support fast protection switching and fast convergence.
Support BFD for VRRP/BGP/IS-IS/RIP/OSPF static routes, etc.
Support NSR/GR for OSFP/BGP/IS-IS etc.
The hardware of the control engine and the switching fabric board is independent of each other, which realizes the physical separation of the control plane and the forwarding plane. The control engine is 1+1 redundant; the switching fabric board is N+M redundant; the fan system is redundantly designed; the power module is N+M redundant ; Maximize the fault isolation capability and reliability of the system.
Distributed caching mechanism and refined QoS
In the face of the burst traffic of the next generation data center, the "distributed ingress cache" technology is innovatively adopted. Each port can precisely perform accurate bandwidth allocation and traffic shaping for all service flows flowing to the port, and the precise scheduling of the forwarding plane ensures that the distributed cache in the direction of ingress is supported, and the cache space distributed on each line card is effectively shared and utilized with a better caching effect.
The network application model has been transformed from C/S to B/S model. The change of application mode has led to the increase of network burst traffic and the large cache mechanism has become an urgent requirement of network equipment. The S12500R supports 1600ms burst traffic per 10 Gigabit port, combined with the distributed ingress caching mechanism, it meets the needs of high burst traffic in large data centers.
A single chip supports 8GB cache, and the line card supports a maximum of 32GB (4*8GB, each chip is independent and cannot be shared).
The whole machine supports a maximum of 64K hardware queues, supports refined QoS and traffic management. It can be configured to assign different priorities and queues to different users and different service flows according to requirements, ensuring different bandwidth, service delay and jitter performance.
Comprehensive maintenance and inspection mechanism
The online status detection mechanism works through a dedicated maintenance engine. It can detect the switching network board, backplane communication channel, business communication channel, key chips, memory and other parts of the device. Once the relevant module fails, it will be reported to the system through EMS.
The board isolation function can isolate the designated board from the forwarding plane and no longer participate in the forwarding. The isolated board is still in the control plane and can be managed. The board can perform real-time diagnosis, CPLD upgrade and other business processing, without affecting the business of the whole system.
Supports Ethernet OAM and provides a variety of device-level and network-level fault detection methods.
Open Application Architecture
The S12500R series products are designed based on the OAA (Open Application Architecture) concept and innovatively launch an open service platform.
Green
Through the intelligent EMS engine system, the S12500R series products support the intelligent management of power supply, and can support the sequential power-on of single boards (reduce the power shock caused by the simultaneous power-on of single boards, improve equipment life, and reduce electromagnetic radiation), and can control power-off of the singleboard, isolate faulty/idle boards, and reduce system power consumption.
The fans of the S12500R series are high-efficiency PWM speed-adjustable fans, which support stepless speed regulation. The system can automatically collect the board temperature, calculate the fan speed adjustment curve according to the actual situation of the device, and deliver the speed adjustment command to the fan. The system supports fan status monitoring (speed monitoring, fault alarm, etc.), which can automatically adjust the speed according to the ambient temperature and board configuration, reduce equipment power consumption and operating noise, effectively reduce ambient noise and prolong fan life.
S12500R series products support automatic detection of internal ports. When a slot is not configured with an interface board, or when a port is not connected to a cable, the system can automatically close the corresponding internal port, saving the power consumption of the whole machine.
