Ethernet Switch / Router - Efficient and Massively Customizable

Features

• Full wire-speed on all ports for all Ethernet frame sizes.
• Store and Forward shared memory architecture.
• Support for Jumbo frame packets of any size limited only by the available packet buffer memory.
• Input and Output mirroring.
• IPv4/IPv6 routing with longest prefix match and direct host tables.
• MPLS switching supporting push/pop/swap/penultimate-pop operations.
• Virtual Routing Functions allowing per customer routing tables.
• ECMP next hop selection.
• Classification on L2 source and destination address, VLAN and Ethernet Type.
• Classification on L3 source and destination address, TOS and protocol.
• Classification on L4 source and destination ports.
• Classification actions are drop packet, send to CPU, redirect to port, assign a new egress queue priority and update statistics, update VLAN header.
• Ingress and Egress packet filtering based on protocol type, VLAN, L3 protocol, L4 protocol.
• Source MAC and Destination MAC range filtering with actions to drop, send to CPU, send to port and assign queue priority
• Hash based L2 MAC table with optional hash collision CAM and support for static entries. Support for unicast and multicast L2 forwarding.
• Hardware based wire-speed learning and aging of L2 addresses. Optional hardware assisted software learning and aging.
• VLAN table optionally supporting more than 4k entries.
• Packet VLAN operations are push, pop, swap, penultimate-pop. Up to three operations per packet can be performed.
• Flexible mapping of 802.1q, MPLS Exp, IPv4/IPv6 TOS byte to egress queue priority.
• Scheduling based on a combination of strict priority schedulers, deficit weighted round robin (DWRR) queue schedulers and rate limiting token buckets. 1-8 queues per egress port.
• Link aggregation with configurable field selection for the hash function.
• Spanning tree & Multiple spanning tree support.
• Buffer memory resource management with configurable limits per egress port and queue ensuring separation for all traffic classes.
• Drop counters for all packet drop cases.
• CPU interface supporting multiple outstanding transactions for high speed access.
• Dedicated port for packets to / from CPU with additional packet header to simplify software processing and controlling processing of packets from CPU. Support for setting queue priority and packet truncation based on packet type.
• Queue management: disable queuing, disable scheduling, drain queue, redirect port.
• Multicast/Broadcast storm control based on packet rate or byte rate per port with separate rates for flooding, broadcast and multicast.
• Integrates seamless with Open Cores, Xilinx and Altera MACs.
• IEEE 1588v2 PTP Transparent Clock two-step support.

Benefits

• Quick customization thanks to a massively parametrized design, and the unique FlexSwitch tool-chain
• Port speeds from 10 Mbit/s to 100 Gbit/s. Mixed port speeds are supported.
• Number of ports from 4 to 128 with optimized design for each configuration.
• All table sizes can be configured such as L2 hash tables, VLAN tables, L3 LPM and direct host tables, classification tables etc.
• Buffer memory size.
• Number of queues per port.
• Feature set. Most features can selectively be added or removed and the design will be automatically optimized for the chosen feature set.
• Design, datasheet and YAML files are automatically created based on the chosen parameter set.

Deliverables

• IP core delivered as non-encrypted Verilog 2001 source code.
• Datasheet with theory of operations and automatically created register description.
• Easy to parse YAML file for register mapping.
• Verilog testbench for checking simulator compliance and as an example of driving the cores interfaces.

Applications

• Enterprise swiches
• Carrier switches
• Datacenter switches
• ToR swiches
• 5G networks
