) Both the enterprise and Metro network core face the same challenges. Following the 80/20 rule, 80% of the current capacity will pass through the network core. This creates huge pressure on the network, and combined with the development of new applications, the network core faces ever-increasing challenges.
1. No network stoppage
It can be seen that enterprises are now shifting their attention from operation cost to network reliability. The entire network core needs to have maximum reliability and stability, and therefore must operate continuously with no network downtime.
2. Network security
Networks must protect against network virus, software loopholes, worms, Trojans, hackers and other threats. The massive security dangers are threatening the internal networks of all enterprises, and a network core stoppage would paralyze the entire network. Therefore it is imperative that the network core equipment have excellent defense capabilities, to guarantee security and stability in the entire network.
3. New applications increasingly bandwidth hungry
Due to an increase in applications that rely on high bandwidth availability, such as multimedia and video applications, a greater strain is being placed on existing networks. With the increase in the number of servers and larger storage devices, along with more and more streaming content, businesses often find there is a degradation in productivity and network performance leading to users becoming dissatisfied with the existing network.
4. Future proofed networks for more applications, more users
Networks that are presently reaching their capacity, or are already showing signs of struggling under an extra burden are finding that in the near future, their network will be wholly unsuitable. This is because the trend towards bandwidth hungry applications and large file transfers are likely to continue and indeed increase. Existing technologies and existing networks, no matter how well designed and implemented, could soon find they can no longer meet the requirements because of the strain users are placing upon the network.
The H3C S9500/S7500 series switches are a new-generation 10G core routing switches purposely developed by H3C with bandwidth-hungry applications in mind. The H3C S9500/S7500 series switches are suitable for deployment in enterprise campus networks core layer and carriers' IP metropolitan-area network (MAN) core or distribution layer for intelligent, scalable architecture and converged, secure and reliable performance.
Integrated with multiplex service categories, powerful QoS guarantee, a complete security management mechanism and carrier-class reliability, the H3C S9500/S7500 series easily matches and goes beyond customer expectations and continues to satisfy their requirements for maximum network uptime, comprehensive network security, and scalable and flexible services.
1. Advanced System Structure
The H3C S9500/S7500 series introduces distributed system architecture and powerful ASICS chips for high-speed routing, and uses crossbar technologies for packet switching. This creative combination greatly improves the forwarding performance and expansion capabilities of the routing switch.
Ideal for powerful hardware platform upgrade capabilities, the H3C S9500/S7500 series have a large number of bus interfaces on the backplane for future system expansion. The system switching capacity can be expanded smoothly to meet the ever-increasing bandwidth needs and user-investment protection.
2. 10 Gigabit Interfaces Supported
The H3C S9500/S7500 series includes an industry-leading 10 Gigabit Ethernet platform and delivers an intelligent and economical solution for the enterprise campus aggregation network. The H3C series switches set 10GE network standards by providing a powerful QoS, guarantee, rich service features including ACL, strategic routing and security and wire-speed forwarding.
3. Carrier-Class Reliability Design
The H3C S9500/S7500 series adopts a distributed processing structure to support dual main control switching units with all interface modules and power supply modules hot swappable and in a passive backplane design. The power system equips dual power inputs following the 1+1 redundant hot back-up mechanism. For reliability, the switches are built to meet strict requirements for carrier-class network reliability (99.999%).
4. Complete Security Mechanism
The H3C S9500/7500 series deploys the 802.1x mode for access user authentication, secure SNMPv3 NM protocol and MD5 encrypted authentication of OSPF v2, RIP v2 and BGP v4 packets. By distinguishing different users of various service levels, the H3C S9500/7500 series have different configuration privileges and provide two user authentication modes: local authentication and RADIUS authentication with the standard RADIUS protocol and SSH for access safety. The rich traffic control mechanisms supported include ACL based on source and destination IP address, MAC address and port number.
H3C S9500 and S7500 series multi-service core switches offer the security, performance and reliability demanded by enterprises of all sizes in any industry. With full-function features for guaranteed QoS, carrier-class reliability, the H3C 10GE platform can support the deployment of IP-based network services and applications like VoIP, wireless and video conferencing to empower companies and drive growth.
