Abstract

Today, fixed form-factor routers and switches are the norm. However, they do not have much ability to perform general purpose computing. As described herein, a pluggable compute enhances/augments the abilities of fixed form-factor routers and switches without requiring the production of excessive amounts of hardware.

ABSTRACT

Today, fixed form-factor routers and switches are the norm. However, they do not

have much ability to perform general purpose computing. As described herein, a pluggable

compute enhances/augments the abilities of fixed form-factor routers and switches without

requiring the production of excessive amounts of hardware.

DETAILED DESCRIPTION

What is desired is a simple way to add needed general purpose computing abilities

to any router or switch on a transceiver port (e.g., Quad Small Form-factor Pluggable

(QSFP), Small Form-factor Pluggable (SFP), CPAK, CFP, etc.). A processor (e.g., Intel®

mobile central processing units (CPUs), Intel AtomTM, Advanced Reduce Instruction Set

Computer (RISC) Machine (ARM) such as ARM Cortex®, etc.) and memory may be

installed on a form-factor small enough to fit into a transceiver module. The memory may

include static random access memory (SRAM), dynamic random access memory DRAM,

and non-volatile (storage) memory. This may allow for the expansion of computing with

ease and enable true service chaining.

In an example, an Intel CoreTM m5, Atom x5, or ARM processor, double data rate

type three (DDR3) or double data rate type four (DDR4) DRAM, and a small form-factor

solid state drive (SSD) may be fit in a transceiver module / QSFP28 / etc. so as to make

that pluggable QSFP/transceiver a general purpose computer that plugs into a router or a

switch. The QSFP or transceiver thus no longer functions only as an optics module but as

a pluggable computing unit. The power needed to run a QSFP28 port is sufficient to run a

low power central processing unit (CPU) and required memories.
