Silicom’s 10 Gigabit Ethernet PCI Express content aware director Bypass server adapters is designed for servers and high-end appliances. The Silicom content aware director server adapter is designed with an on board smart routing architecture that enables packets to be redirected or dropped based on defined rules.
The Silicom’s 10 Gigabit Ethernet content aware packet director reduces host system process since only packets that are defined to be targeted to the host systems are routed to the host; other packets can be routed to the other port or can be dropped by the content aware hardware routing architecture.
The Silicom’s 10 Gigabit Ethernet content aware packet director is targeted to network applications that needs to process, monitor or bypass packets based on defined rules. The adapter supports three main modes of operation: Content Aware Bypass, Content Aware TAP and content Aware filtering NIC.
Content Aware Bypass
Silicom’s 10 Gigabit Ethernet content aware director provides intelligent packet redirection capability where rules specify which packets are directed to the host system and which packets are directed to the other port (Bypass).
.
Content Aware TAP
Silicom’s 10 Gigabit Ethernet content aware director provides intelligent packet redirection capability where all packets are directed to the other port (Bypassed) and rules specify which packets are copied to the host system ( TAP).
Content Aware Filtering NIC
Silicom’s 10 Gigabit Ethernet content aware provides intelligent packet redirection capability where rules specify which packets are directed to the host or dropped.
The Silicom 10 Gigabit Ethernet PCI Express content director server adapter is based on Intel 82599EB Ethernet controller and a L3 switch router. The Silicom’s 10 Gigabit Ethernet PCI Express adapter is based on standard L2 driver and with the content director engine reduces CPU host system processing.
The Silicom 10 Gigabit Ethernet PCI Express content aware server adapter offers simple integration into any PCI Express X8 to 10Gigabit Network.
Silicom’s 10 Gigabit Ethernet PCI Express content aware supports L1 Bypass. The adapter can Bypass its Ethernet ports on a host system failure, power off, or upon software request. In Bypass mode, the connections of the Ethernet network ports are disconnected from the interfaces and switched over to the other port to create a crossed connection loop-back between the Ethernet ports. Hence, in bypass mode all packets received from one port are transmitted to other port and vice versa. This feature enables to bypass a failed system and provides maximum up time for the network.

Functional Description
Director - Content Aware Bypass
Silicom’s 10 Gigabit Ethernet content aware director Provides intelligent packet redirection capability where rules specify which packets are directed to the host system and which packets are directed to the other port (Bypass).
Figure 1: Content Aware Bypass Functional Block Diagram
Figure 1 illustrates functional block diagram of content aware Bypass:
Packets received in port A and meet rule are directed to port B, other packets are directed to port C (Bypass).
Packets received in port C and meet rule are directed to port D, other packets are directed to port A (Bypass).
Director - Content Aware TAP
Silicom’s 10 Gigabit Ethernet content aware director Provides intelligent packet redirection capability where all packets are directed to the other port (Bypassed) and rules specify which packets are copied to the host system (TAP).
Figure 2: Content Aware TAP Functional Block Diagram
Figure 2 illustrates functional block diagram of content aware TAP:
Packets received in port A and meet rule are directed to ports B and C (TAP), other packets are directed to port C (Bypass).
Packets received in port C and meet rule are directed to ports D and A (TAP), other packets are directed to port A (Bypass).
Director - Content Filtering NIC
Silicom’s 10 Gigabit Ethernet content aware provides intelligent packet redirection capability where rules specify which packets are directed to the host or dropped
Figure 3: Content Aware Filtering NIC Functional Block Diagram
Figure 3 illustrates functional block diagram of content aware TAP:
Packets received in port A and meet rule, direct to port B. Packets received in port A and do not meet rule are dropped.
Packets received in port C and meet rule, direct to port D. Packets received in port C and do not meet rule are dropped.
Bypass / Disconnect
Silicom’s Bypass adapter supports Normal, Bypass and Disconnect modes. In Normal mode, the ports are independent interfaces (see Figure 1: Normal mode, one Bypass pair is illustrated).
Figure 4: Normal Mode Functional Block Diagram
In Bypass mode, the connections of the Ethernet network ports are disconnected from the interfaces and switched over to the other port to create a crossed connection loop-back between the Ethernet ports. The connections of the interfaces are left unconnected. (See Figure 2: one Bypass pair illustrated)
Figure 5: Bypass Mode Functional Block Diagram
In Disconnect mode, the transmits connections of the interfaces are disconnected from the ports. The switch / router connected to the adapter does not detect link partner (See Figure 3)
Figure 6: Disconnect Mode Functional Block Diagram
Silicom’s Bypass server adapter supports software programmable to select Normal, Bypass or Disconnect modes. Silicom’s Bypass adapters supports Disable Bypass, Disable Disconnected capabilities; hence, if those adapters receive Disable Bypass capability / Disable Disconnect commands, the adapter does not Bypass / does not Disconnect its Ethernet ports, The Disable Bypass Capabilities are reserved also after power off. This feature enables to emulate a standard NIC.
