IS100
Silicom 100G Intelligent Bypass Switch
Product Description
Silicom 100G Intelligent QSFP28
Bypass switch (IS100) is Silicom
forth generation of an active
external Bypass switch that protects
network integrity from network
failures and network maintenance. The Silicom intelligent Bypass switch (IS100) is a self-generating heartbeat and controls the
network switch mode of operation.
The Silicom IS100G1U is a 1U host system which supports up to two modules. A module supports one Bypass segment per
module.
The Silicom IS100 supports 100 Gigabit Ethernet Multimode Fiber (100GBase-SR4) ,(100G Base-SR10 ) and 100 Gigabit Single
mode fiber (100GBase-LR4) network standards. Each 100G Bypass module includes two MPO / LC ports for network ports, and
two QSFP28 ports for the attached in-line network system.
The Silicom Intelligent Bypass switch (IS100) supports four modes of operations: Inline, Bypass, Tap and Linkdrop. In Inline mode,
the IS100 diverts inline network traffic to attached in-line network system. In Bypass mode, the IS100 does not divert the traffic to
the attached in-line network system and diverts it to other network link. In Tap mode, incoming traffic in port NET0 is mirrored to
port MON0 and incoming traffic in port NET1 is mirrored to port MON1.In Linkdrop mode the IS100 disables the links on the
network ports (NET0, NET1). The IS100 simulates switch / router cable disconnection.
The IS100 generates the heartbeat packets and transmits the heartbeat packet to the in-line Monitor / Network appliance port, the
Monitor Network appliance receives the heartbeat packets and transmits is to its other port (bridges the heartbeat packet). The
IS100 detects back the heartbeat packet and maintains the Inline mode.
The IS100 sets to Bypass, Tap or Linkdrop when it does not receive back the heartbeat packet from the Network / Monitor
appliance. When the Network / Monitor appliance recovers, it transmits back the heartbeat packet and the Intelligent switch sets to
Inline. The IS100 bypasses its Ethernet Monitor ports on event of power failure, Link failure, in-line software application system
hang or user request.
The IS100 includes Double Bypass Safe architecture. The Silicom Double Bypass safe architecture is based on two Bypass routing
circuitry: An Active Bypass circuitry and Passive Bypass circuitry. If the internal active bypass routing circuitry fails, the passive
Bypass routing circuitry is activated.
