LN-NEO-2212-MLS from LancsNet is programmable FPGA-base product with provided full set of layer 2 and layer 3 management features. It delivers maximum throughput where you need it — to high-performance workgroups at the edge of the network, or as a backbone for Gigabit Ethernet switches and high-speed servers in mid and small-sized networks. Moreover, LN-NEO-2212-MLS switch also comes equipped with 4 SFP slots, giving you greater network flexibility.

With 24 Gbps switching capacity, the LN-NEO-2212-MLS can handle small and medium amounts of data in a secure topology linking to backbone or high capacity servers for ISP and enterprise VoIP, video streaming, and multicast applications.


Hardware platform based on FPGA

LancsNet present a high-throughput FPGA design for supporting high-performance network switching. FPGAs have recently been attracting attention for datacenter computing due to their increasing transceiver count and capabilities, which also benefit the implementation and refinement of network switches. Our solution replaces the crossbar in favour of a novel, more pipeline-friendly approach, the “Combined parallel round-robin arbiter”. It also removes the overhead of incorporating an often-iterative scheduling or matching algorithm, which sometimes tries to fit too many steps in a single or a few FPGA cycles. The result is a network switch implementation on FPGAs operating at a high frequency and with a low port-to-port latency.


Robust Layer 2 Features

The LN-NEO-2212-MLS series can be programmed for basic switch management functions such as port speed configuration, port aggregation, VLAN, Multiple Spanning Tree Protocol, WRR and bandwidth control. This switch provides 802.1Q tagged VLAN. By supporting port aggregation, the LN-NEO-2212-MLS series allows the operation of a high-speed trunk combined with multiple ports.

Layer 3 Routing Support

The LN-NEO-2212-MLS series enables the administrator to conveniently boost network efficiency by configuring Layer 3 static routing manually, and the RIP or OSPF settings automatically. The RIP can employ the hop count as a routing metric and prevent routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The OSPF is an interior dynamic routing protocol for autonomous system based on link state. The protocol creates a database for link state by exchanging link states among Layer 3 switches, and then uses the Shortest Path First algorithm to generate a route table based on that database.

Strong Multicast

The LN-NEO-2212-MLS series supports abundant multicast features. In Layer 2, it features IPv4 IGMPv1/v2/v3 snooping and IPv6 MLD v1/v2 snooping. In Layer 3 multicast protocols, it features IGMPv1/v2/v3 and DVMRP. With Multicast VLAN Register (MVR), multicast receiver/sender control and illegal multicast source detect functions which make the LN-NEO-2212-MLS series great for any robust networking.


Full IPv6 Support

The LN-NEO-2212-MLS series provides IPv6 management and enterprise-level secure features such as SSH, ACL, WRR and RADIUS authentication. It thus helps the enterprises to step in the IPv6 era with the lowest investment. In addition, you don’t need to replace the network facilities when the IPv6 FTTx edge network is built.


Excellent Layer 2 to Layer 4 Traffic Control

The LN-NEO-2212-MLS series is loaded with powerful traffic management and WRR features to enhance services offered by telecoms. The WRR functionalities include wire-speed Layer 4 traffic classifiers and bandwidth limitation which are particularly useful for multi-tenant unit, multi-business unit, Telco, or network service applications. It also empowers the enterprises to take full advantage of the limited network resources and guarantees the best in VoIP and video conferencing transmission.


Powerful Security

The LN-NEO-2212-MLS series supports ACL policies comprehensively. The traffic can be classified by source/destination IP addresses, source/destination MAC addresses, IP protocols, TCP/UDP, IP precedence, time ranges and ToS. Moreover, various policies can be conducted to forward the traffic. The LN-NEO-2212-MLS series also provides IEEE 802.1x port based access authentication, which can be deployed with RADIUS, to ensure the port level security and block illegal users.


Efficient and Secure Management

LN-NEO-2212-MLS supports various user-friendly standard management features, such as intuitive web-based Graphical User Interface (GUI) or industry-standard Command Line Interface (CLI), either administration traffic can be protected through SSL or SSH encryptions. SNMP (v1/2/3) and RMON support enables the switch to be polled for valuable status information and send traps on abnormal events. This sharing of vital management information saves time and money. With link aggregation, spanning tree protocol (STP/RSTP/MSTP) and virtual stack, a highly intelligent and scalable topology could be established, fulfilling the enterprise customers´s requirement of building a unified, resilient network.
