Lithe IP / programmable networking

Customize &
optimize your hardware.

Lithe is Pantherun’s configurable Layer 2 and Layer 3 networking suite for teams building switches, routers and connected systems. Deploy it as portable software or synthesisable RTL inside an FPGA or SoC.

Select the functions and port mix the product actually needs.

02Parallel data path

Move and classify traffic directly in programmable logic.

03Field adaptable

Update networking capabilities as protocols and requirements evolve.

04One integrated system

Combine switching, routing, compute and optional security on one device.

Wirespeed switching.
Intelligent Routing.

Use the Layer 2 foundation on its own or add Layer 3 functions to move traffic between network zones on the same programmable platform.

L2 / DATA LINK

Lithe Layer 2

A managed Ethernet switching foundation for scalable LAN, MAN and industrial networks, implemented in software or directly in programmable logic.

  • VLAN, QinQ and MAC learning
  • STP, RSTP, MSTP and ERPS rings
  • LACP, QoS and traffic shaping
  • ACLs, 802.1X and secure management
  • IGMP snooping and multicast control
  • Ethernet OAM and network monitoring
L3 / NETWORK

Lithe Layer 3

Routing functions extend the same configurable platform across subnets, zones and redundant gateways without adding a separate network processor.

  • Inter-VLAN and static IPv4 routing
  • RIP, OSPFv2 and OSPFv3
  • BGP and IPv4/IPv6 dual stack
  • PIM multicast routing
  • VRRP gateway redundancy
  • Policy controls at the routed edge

Network packet processing
at wire speed.

Lithe can meet a product at the FPGA fabric, processor, operating system or packaged-device boundary.

01 / RTL

Synthesisable logic

Encrypted or unencrypted IEEE 1735-compatible RTL can be built as a soft block inside an FPGA or SoC FPGA.

02 / SOFTWARE

Portable network stack

A software implementation supports x86, ARM and RISC processor architectures across common operating systems.

03 / PLATFORM

Chip + IP packages

Choose integrated chip packages or IP-only configurations for 1G and 10G designs with different port densities.
