MB86977 Overview
U 4 t munication Control e e h ASSP S a t a D IP. PACKET FORWARDING ENGINE w w The MB86977 is an LSI that enables processes that previously were handled through software, such as packetdestination transferring and filtering, to be handled through hardware, thereby achieving a full wire speed bidirectional LAN-WAN throughput of 100 Mbps. The IP forwarding can be applied to both IPv4 and IPv6 packets at full wire...
MB86977 Key Features
- IP packet forwarding
- Routing operations such as Ethernet MAC Address replacement, TTL reduction and checksum generation done in hardware
- Supports both IPv4 and IPv6
- Supports PPPoE Tunneling and IPv6 over IPv4 Tunneling at WAN Interface (Continued)
- NAT (NAPT)
- NAT operations such as IP Address replacement, Transport layer port number replacement, and checksum generation done in
- Supports PPPoE Tunneling and IPv6 over IPv4 Tunneling at WAN Interface
- Supports IPv4 only
- Layer 3/4 Filtering
- Filtering based on IP Address (Dst and/or Src, supports both IPv4/IPv6)
