ALPHA BRIDGE- LAYER-3 Switches (AS300/26/C)
Product Overview
Alpha Bridge AS300/26/C is a new generation of full 10GE TOR switches oriented for high-performance computing, data centers, and high-end campuses. It adopts our most advanced hardware architecture designs.
AS300/26/C (1U height) supports up to 2.56Tbps switching capacity and 24 10GE/GE SFP+ ports,2 100GE/40GE QSFP28ports.
Developed based on ABROS software platform Alpha Bridge with its independent intellectual property rights, AS300/26/C provides high-performance L2/L3/L4 wire-speed switching capacity by integrating services such as IPv6, network security, flow analysis, and virtualization, with high reliable techniques including continuous forwarding, graceful restarting and loop network protection, all which works efficiency withing the AS300/26/C fabric for guaranteed maximum runtime.
Carrier-Level Aggregation Layer-3 Ethernet Switch Innovative AVSS (ABTPL Virtual Switch System):
virtualize multiple physical devices into one. The virtual system’s performance, reliability, and management capabilities combine to outperform individual physical devices.
Improved Performance:
High Reliability:
Easy Management:
Improved Performance:
AVSS fully utilizes each link in the physical device cluster, which avoids STP blocking on links and protects the original link to the maximum extent.
High Reliability:
The advanced distribution mechanism and efficient cross-physical link aggregation link functions separate the logical control plane, service control plane, and service data plane. Thus, the device can support continuous layer 3 routing forwarding, avoiding service interruption due to a single point of failure.
Easy Management:
AVSS realizes single IP management, greatly improving networking efficiency and lowering operating costs

Rich Data centre Services
- AVSS (ABTPL Virtual Switch System) AS300/26/C supports AVSS, which can virtualize multiple physical devices into a single logical element. The virtualized system is superior to the independent physical device in performance, reliability, flexibility and management.
- Doubled Performance: The virtualized system makes the best use of each link in the device and avoids blocking of STP to the links.
- High-reliability: Based on the advanced distributed processing technique and the efficient function of cross-physical device link aggregation, the AS300/26/C provides non-stop layer-3 routing forwarding and avoids single points of failure.
- Flexibility: The virtual cluster function of the AS300C allows the distance of a cluster system to expand over up to 80KM, breaking the geographic restrictions of traditional cluster techniques.
Easy Management: The whole virtual system realizes single IP unified management and simplifies the management of network device and network topology.
Security+
- Equipment-level security: The advanced hardware infrastructure design ensures packet protection, prevents DoS-/TCP-related SYN Flood, UDP Flood, Broadcast Storm or large traffic attacks, and supports level-based command line protection, endowing different levels of users with different management permissions.
- Perfect security authentication mechanisms: IEEE 802.1x, Radius and Open source TACACS+.
- AS300/26/C supports storm/multicast/unicast limit, ensuring the normal running of equipment in harsh network conditions.
- AS300/26/C supports perfect ring detection mechanism, ensuring the long-term stable running of network. Supports port isolation within the same VLAN, DHCP-Snooping, and IP plus MAC plus Port binding for ensuring user data security.
Versatile IPv6 Solutions
- Supports the IPv6 protocol suite, IPv6 neighbour discovery,
ICMPv6, path MTU discovery, DHCPv6, etc. - Supports Ping, Traceroute, Telnet, SSH, ACL based on IPv6.
- supports MLD, MLD Snooping, IPv6 static routing, RIPng, OSPFv3 and BGP4+, etc.
- Supports IPv6 tunnel: manual tunnel, automatic tunnel, GRE tunnel, 6 to 4 tunnel, ISATAP.
- AS300/26/C supports IPv4 transiting to IPv6: IPv6 manual tunnel, automatic tunnel, 6 to 4 tunnel, ISATAP tunnel.
Data centre Level High-reliability
- AS300/26/C adopts HPS (Hitless Protection System). The key components of AS300/26/C such as the power system and the fan system support redundancy in design. All system modules support hot-swap and seamless switching without need of manual intervention.
- AS300/26/C supports redundancy protection mechanisms such as STP/RSTP/MSTP protocol, VRRP protocol, ring network protection, dual uplink active/standby link protection and LACP link aggregation.
- AS300/26/C supports ISSU (In-Service Software Upgrade), guaranteeing non-stop forwarding of service data while the system is upgrading.
AS300/26/C supports BFD and realizes fault detection and service recovery in seconds through linking with layer-2 or layer-3 protocol. - AS300/26/C has perfect Ethernet OAM, 802.3ah, 802.1ag and ITU-Y.1731 which can monitor the network operating state in real time and rapidly detect and locate the malfunction.
High Reliability (99.999%): The MTTR of the AS300/26/C is 50ms, satisfying the requirement for reliable delivery of carrier-level service.
