Frequently Asked Questions

Q: What is The Telx Internet Exchange (TIE) ?
A: The TIE is an an Internet exchange point (IX or IXP) or "public peering point" thats allows Internet Service Providers (ISPs) to exchange traffic inexpensively through a common switch fabric usually through on settlement-free basis. By connecting to the TIE facilities ISPs can peer with any other ISP that is connected to same the TIE facility, provided the peeering ISPs reach a bilateral peering agreement. For a good film about the basics of an IX, check out the Euro-IX created film The Internet Revealed: A film about IXPs v2.0

Q: What is an Internet Exchange Point?
A: An Internet exchange point (IX or IXP) is a physical infrastructure that allows different Internet service providers (ISPs) to exchange Internet traffic between their networks (autonomous systems) by means of mutual peering agreements, which allow traffic to be exchanged without cost. IXPs reduce the portion of an ISP's traffic which must be delivered via their upstream transit providers, thereby reducing the Average Per-Bit Delivery Cost of their service. Furthermore, the increased number of paths learned through the IXP improves routing efficiency and fault-tolerance.

Q: Who can I peer with?
A: Potentially, you can peer with any of the ISPs that are participants of the same TIE facility. However, you must contact each prospective peering ISP to verify that you meet its peering policies. You can peer with the TIE Route Servers to automatically peer with many participants.

Q: Does TIE have Route Servers?
Telx offers its participants the opportunity to peer via the TIE Route Servers. We operate two route servers on every TIE. For example and The route servers are based on the BIRD routing daemon. Both offer the peers the possibility of filtering based on their IRRdb entries. Every participant has the ability to filter out any number of peers. The route servers maintain per-peer routing tables to ensure the possibility of maintaining your peering policy.

Q: What do I need to peer at TIE?
A: The ISP must provide for the following:

  • A border router to connect to the port on a TIE switch
  • Somebody who can configure the border router
  • An exchange point IP address for the border router
  • An Autonomous System Number (ASN) to identiy the ISP
  • A bilateral peering agreement with each of the peering ISPs (most often this is a verbal or "handshake" agreement) or two BGP sessions with the TIE Route Servers.

Q: Where do I get an IP addresses?
A: Telx manages our own IPv4 Address allocatons. Once you have an IPv4 address, your IPv6 address is based on your IPv4 address where the "last-octet" is the decimal equivalent of the last octet of your IPv4 allocation. For example: IPv4 corresponds to IPv6 2001:478:132::254 out of the 2001:478:132::/64 subnet.

Telx Internet Exchange IP Addresses
City IPv4 Subnet IPv6 Subnet
Atlanta 2001:478:132::/64
Dallas 2001:504:17:114::/64
New York 2001:504:17:115::/64
Phoenix 2001:478:186::/64

Q: How do I contact TIE Network Operations?
A: Email and if an emergency call (404) 325-2714.

Q: What connection types and speeds are available?
A: You can connect via copper or fiber.  Available speeds are 1Gbps, Nx1Gbps, 10Gbps and Nx10Gbps (via single more fiber only)

Q: Is there an AUP (Acceptable Use Policy)?
A: Please see the posted AUP.

Q: Is there a SLA (Service Level Agreement)?
A: Please see the posted SLA.

Q: What is the Route Viewer
A: Telx maintains a route viewer at every TIE point. We use the route viewer for monitoring your connectivity. In addtion to watching your port's up/dwn status, we monitor a BGP session with the route viewer. Once you are connected you must peer with our route veiwer. The route viewer should never advertise any routes to you so you might want to filter all incoming advertisments from the route viewer. We ask that you send your "standard" peering routes. The data collected by the RV is used for monitoring and support purposeses. The RVs use the ASN 65535 and are always the ".1" IP on the TIE (both for IPv4 and IPv6).

Q: Do you have any customer usage graphs?
A: Please signup for the Participant Portal for access to your usage graphs.

Q: Do you provide sFlow data analytics?
A: Yes, we enable participants to see current traffice levels per ASN destination. Please signup for the Participant Portal for access to your sFlow data. Telx uses Guavus as our exclusive data analytics partner. Guavus has several advanced reporting options that can be purchased in addition to the free reports provided on the Participant Portal.

Q: What other features can be found on the Participant Portal
A. The Particiapt Portal has many features. We are continually looking to expand the functionality. Below is a list of some of the features.

  • Alert History - See the last seven days of errors and outages along with any planed outages/work
  • Interface Management - Allows you to view usage details, control your static MAC address, shutdown, bring up or bounce any of your interfaces.
  • sFlow Data Analytics - Allows you to see how much traffic your are exchanging with other particiants.
  • Peering Manager - Allows you to track peering sessions and send e-mails to other peering coordinators to help speed-up communications with other participants.
  • Manage Contact Preferences - Allows you to manage which e-mail address that you want other Participants to use to contact you.
  • IX Aggregated Usage - Allows you to see the aggregate IX usage graphs
  • Detailed IX Statistics - Allows you to see breakdown of IX usage and other helpful statistics
  • Looking Glass - Allows you to view BGP announcements to out Route Monitors, and run traceroute and ping commands from the Route Monitor.
  • Bulk Mail Manager - Allows you to send bulk emails to participants to announce a new presence, maintenance work or other important communications.
  • Java IRC client - Connect to #telx on via a web based IRC client
  • E-mail notifications - Setup your account to receive e-mail notifications when any of your ports or BGP sessions change state (up/down).

Q: Do you support Gigabit Ethernet Port Link Aggregation?
A: Yes we do! Please check out Link Aggregation Guide.

Q: Do you provide any public uage statistics?
A: While our Participant portal has in-depth statistics, we conform to the Packet Clearing House (PCH) Good Practices in Internet Exchange Point Documentation for publication of public statistics.
