![]() This is normally expressed as Packets-per-second, or PPS. IPsec) or IDS/IPS, the true measure of router performance is packets forwarded per unit time. There are far too many inefficiencies in the kernel routing stacks for FreeBSD, OpenBSD, and even linux to make this work.Įxcept for encryption (e.g. ![]() No, you can't do it with kernel networking. The performance difference between the two were typically an order or two of magnitude. The data plane was often layered, where features not handled by the hardware data plane were punted to a software only data path running on a more general CPU. While these were still programmable in a sense, they certainly weren't programmable by anyone but a small handful of people who developed the hardware platform. As the needs and desires for more speeds and feeds grew, the data plane had to be implemented in ASICs and FPGAs with custom memories and TCAMs. Back in the 80s and 90s the data plane was running in software on commodity CPUs with proprietary software. Traditionally routers were built with a tightly coupled data plane and control plane. Implementation: netmap_delete_command_fn.Can you replace a Cisco ASR with a high-end server (with enough ports) and match performance parity while using freebsd/openbsd? In VPP, netmap interfaces are named as ' netmap-', where ' ' takes one of two forms:Įxample usage Example of how to delete a netmap interface named ' netmap-vale00:vpp1': vpp# delete netmap name vale00:vpp1 Declaration and implementationĭeclaration: netmap_delete_command ( src/vnet/devices/netmap/cli.c line 215) Use the ' ' to identify the netmap interface to be deleted. Implementation: netmap_create_command_fn.ĭelete netmap Summary/usage delete netmap name |valeXXX:YYY.ĭelete a netmap interface. Once the netmap interface is created, enable the interface using: vpp# set interface state netmap-vale00:vpp1 up Declaration and implementationĭeclaration: netmap_create_command ( src/vnet/devices/netmap/cli.c line 152) Defaults to ' slave' if not entered.Įxample usage Example of how to create a netmap interface tied to the linux namespace ' vpp1': vpp# create netmap name vale00:vpp1 hw-addr 02:FE:3F:34:15:9B pipe master master | slave - Optional flag to indicate whether VPP should be the master or slave of the ' netmap pipe'.pipe - Optional flag to indicate that a ' netmap pipe' instance should be created.hw-addr - Optional ethernet address, can be in either X:X:X:X:X:X unix or X.X.X cisco format.This command has the following optional parameters: Where ' YYY' is an existing linux namespace.Where ' valeXXX' is an arbitrary name for a VALE interface that must start with ' vale' and is less than 16 characters.Once created, a new netmap interface will exist in VPP with the name ' netmap-', where ' ' takes one of two forms: - VPP development package for Netmap/VALE, which is a snapshot of the Netmap/VALE repo with minor changes to work with containers and modified kernel drivers to work with NICs.Ĭreate a netmap interface that will attach to a linux interface.Netmap/VALE generates the ' netmap.ko' kernel module that needs to be loaded before netmap interfaces can be created. Together, they provide a high speed user-space interface that allows VPP to patch into a linux namespace, a linux container, or a physical NIC without the use of DPDK. ' netmap' includes ' netmap pipes', a shared memory packet transport channel. ' VALE' is an equally fast in-kernel software switch using the netmap API. ' netmap' is a framework for very fast packet I/O from userspace. Create netmap Summary/usage create netmap name |valeXXX:YYY.
