 S7500 Series 10G Core Router Switches
The S7500 series switches are high-end smart routing switches designed for nextgeneration enterprise networks. The S7500 design is based on TG-NET's intelligent multi-layer switching technology to provide intelligent service optimization methods, such as MPLS VPN, traffic analysis,comprehensive H-QoS policies, controllable multicast, load balancing, and security, in addition to highperformance Layer 2 to Layer 4 switching services. The S7500 also features scalability and reliability.

The S7500 can function either as an aggregation or core node on a campus network or in a data center to provide integrated wireless access. The S7500 also offers voice, video, and data services, helping enterprises build an integrated cost-effective end-to-end network.

The S7500 series is available in three models: S7503, S7506, and S7510. The switching capacity and port density of all three models is expandable. Key components work in redundancy mode to minimize risks of system breakdown and service interruption. Using innovative energy-saving chips,the S7500 provides an industry-leading solution for a sustainable energy-saving network.

Powerful service processing capabilities

TG-NET's advanced switching architecture permits rapid bandwidth expansion. The highly expansible backplane enables ports to be upgraded to a rate of 40 Gbit/s, and is compatible with the currently used cards, helping enterprises maximize their ROI.

The S7500 provides high-density 10GE ports, Each S7510 chassis can provide a maximum of 96x10GE ports, meeting the requirements of bandwidth-consuming applications, such as multimedia conferencing and data access.

The S7500's multi-service routing and switching platform meets requirements for service bearing at the access layer, aggregation layer, and core layer of enterprise networks. The S7500 provides wireless access along with voice, video, and data services, helping enterprises build integrated full-service networks with high availability and low latency.

The S7500 supports distributed Layer 2/Layer 3 MPLS VPN functions, including MPLS、MPLS VPN and MPLS TE, implementing VPN access for enterprise users.

The S7500 supports various Layer 2 and Layer 3 multicast protocols such as PIM SM, PIM DM, PIM SSM,MLD, and IGMP snooping. It can provide enterprises with multi-terminal high definition video surveillance and video conferencing services.

 

Carrier-class reliability and visual fault diagnosis

The Hitless Protection System (HPS) of S7500 is 99.999% reliable. The S7500's rack structure uses a passive backplane design. The S7500 provides redundant backup for key components, including MPUs, power supply units, and fans, all of which are hot swappable.

The S7500 implements seamless switchover between the master and slave MPUs and supports graceful restart to ensure nonstop forwarding.At the same time, the functions of S7500 like VRRP, STP and LACP provide further reliability.

 

Enhanced QoS mechanism, improving the voice and video experience

The S7500's H-QoS control mechanisms classify traffic based on information from the link layer to the application layer. With advanced queue scheduling and congestion control algorithms, the S7500 performs accurate multi-level scheduling for data flows, satisfying enterprises' QoS requirements for a variety of services and user terminals.

The S7500 supports hardware-based low delay queues for multicast packets so that the video service can be processed with high priority and low delay. This feature guarantees the high quality of key services in an enterprise, such as video conference and surveillance.

The S7500 uses innovative priority scheduling algorithms to optimize the QoS queue scheduling mechanism for voice and video services. The improved scheduling mechanism shortens the delay of the VoIP service and eliminates the pixelation effect in the video service, improving user experience.

 

High-performance IPv6 service processing, resulting in a smooth transition from IPv4 to IPv6

Both the hardware platform and software platform of the S7500 support IPv6. The S7500 has earned the IPv6 Ready Phase 2 (Gold) designation.

The S7500 supports IPv4/IPv6 dual stack, various tunneling technologies, IPv6 static routing, RIPng,OSPFv3, BGP+, and IPv6 multicast. These features meet the demand for IPv6 networking and combined IPv4 and IPv6 networking.

 

Innovative energy-saving chips, allowing for intelligent power consumption control

The S7500 uses innovative energy-saving chips, which can dynamically adjust power on all ports based on traffic volume. An idle port enters a sleep mode to reduce power consumption.

The S7500 supports IEEE 802.3az Energy Efficient Ethernet and provides the low power idle mode for the PHY line card. If the link utilization is low, the S7700 switches to a lower speed or power PHY to reduce power consumption.

 

Uniform network management

S7500 supports the RFC 1213 SNMP protocol. The internal network management mode adopts the Telnet-based configuration management or the SNMP-based configuration management, realizing uniform network management based on the Broad Director network management platform.
