TTM Network Administration

Network Hardware

Overview

For a standard TT implementation, you must situate your network infrastructure (i.e., TT Gateway servers, switches, routers, and firewalls) within a dedicated computer room with UPS backups and dual power supplies for all servers. Additionally, TT recommends that you invest in backup cooling systems.For specific recommendations on client and server machines, refer to TT Trading Systems - Hardware and Software Requirements Version 7.X.

NIC Teaming

To ensure the reliability of your production trading network, TT does not recommend using a NIC teaming solution. NIC teaming involves configuring multiple physical network cards to appear as a single virtual network interface to other networked applications. While NIC teaming offers extra redundancy, TT has neither tested nor certified any vendor’s virtual NIC drivers with TTM.

Even if the solution appears to be technically capable of supporting TT components under normal conditions, NIC teaming software has been shown to cause serious performance and reliability issues, especially in failover situations.

Note

When investigating connectivity issues, TT will ask you to remove NIC teaming to help determine the root cause of a problem.

Hubs

Do not use hubs in your TT trading system. Hubs slow down network traffic, which in turn causes traders to get their orders to market slower.

Ports

When setting up network hardware, you must open all ports that TTM uses. For a list of these ports, refer to Port Assignments.

Cables

For all in-house cabling, use CAT-5 or better products. You must professionally install and test all cabling used in the TT trading system.

Firewalls

If you create a VPN by using one or more firewalls (e.g., for remote connections), TT recommends that you also use a VPN accelerator card (i.e., hardware assist). The diagram in Multiple Segments illustrates this setup.

Note

Using firewalls introduces latency into network communications.

Routers

Though most exchanges provide routers for you to use when connecting to them, some do not. MISS-based exchanges are an example of ones that do not provide this router.

If you need to NAT between networks, TT recommends you do so with a firewall instead of a NAT router.

Switches

Refer to the following table to determine guidelines for the type of switch you need to connect traders in your TT trading system.
