Extralink Chiron - gigabit switch with SFP+ ports Extralink Chiron is a new generation 24-port Layer 3 switch. It is aimed at IP MAN networks (metropolitan area network), government and corporate networks, and Internet cafes. It is developed on high-performance hardware and supports features such as high-performance ACL, flexible QinQ, 1:1 or N:1 VLAN switching, Ethernet OAM, carrier-level QoS and industry-level 10GE Ether-ring. It also supports Layer 3 routing protocol. High reliability Based on the advanced distribution mechanism and efficient cross-physical link aggregation function, the logic control plane, service control plane and service data plane are separated. This allows Extralink Chiron to support continuous Layer 3 routing redirection, avoiding interruption of service continuity due to a single failure. The Chiron Telecom Level Ethernet Switch supports the Telecom Level Ethernet Protection Protocol with a protection offset time of less than 50 ms, STP/RSTP/MSTP, active and standby uplink backup, and LACP link aggregation to ensure high service reliability. Provides an excellent Ethernet OAM mechanism to monitor network health in real time for quickly locating and detecting problems. Supports In-Service Software Upgrade (ISSU) to ensure seamless data transfer during system updates. It supports support for various L2 multicast features, including IGMP-Snooping, fast-leave and trans-vlan. Flexible and convenient management and maintenance Supports management modes such as console port, Telnet, SSH, etc. Supports WEB management mode, which is easy and efficient, making installation and debugging convenient Supports TFTP file upload/download management Supports ISSU (In-Service Software Upgrade) Carrier-level QoS rules Supports priority retagging and complicated flow classification based on VLAN, MAC, source address, destination address, IP or priority to increase service level Provides flexible bandwidth control policy and supports port/flow based flow limit and also provides line speed redirection of each port to ensure high quality video, audio and data services Supports 8 priority queues per port Supports multiple queue scheduling algorithms e.g. SP, WRR and SP+WRR Versatile IPv6 solutions Supports IPv6 protocol suite, neighbor discovery IPv6, ICMPv6, path MTU discovery, etc. Supports IPv6-based Ping, Traceroute, Telnet, SSH, ACL, meeting the requirements of IPv6 networks for hardware management and service control. Excellent security mechanisms. Advanced hardware infrastructure design realizes level-based packet scheduling and packet protection, prevents DoS-/TCP attacks related to SYN flood, UDP flood, broadcast storm or heavy traffic, and supports level-based protection command line, giving different levels of users different management privileges.
