Guaranteed Traffic Delivery

GTT’s leading Tier 1 IP network includes Nx100G global capacity to easily scale with your business. We transport over 14 Tbps of traffic across the network at any point in time, powering some of the most popular destinations on the internet.

Our global IP network is built upon carrier-class routing infrastructure, allowing bandwidth-heavy traffic to reach its destination with minimal lag or jitter. We continuously upgrade our network and assess performance to eliminate bottlenecks and ensure that there is sufficient capacity to handle sudden, unpredictable demand.

Route Security (RPKI)

GTT is among the first large global Tier 1 operators to apply Resource Public Key Infrastructure (RPKI), a mechanism to make Internet routing more secure. RPKI enables an IP address space holder, authorised at the Regional Internet Registry (RIR) level, to create a Route Origin Authorization (ROA) record, which sets out which Autonomous System can originate their routing prefix. This, in turn, enables network operators such as GTT to perform route origin validation and decline any invalids.

We have deployed RPKI-based route origin validation filtering on all BGP sessions with both clients and peers throughout our global network footprint. With a ROA record covering their IP routes, our clients can rest assured that their IP announcements are further secured from routing leaks or hijacks throughout the entire GTT global network.

About IP transit

IP-transit

Individuals, businesses and organizations connect to the Internet in a variety of ways depending on a multitude of factors. Connecting to the Internet can be through one or a combination of the following: subscribing to the Internet through an Internet service provider, procuring IP transit, and peering. On this page the primary focus is on IP transit, especially for those interested in procuring the service for their organizations.

What is IP transit?

IP transit is when a large network (or upstream) provider allows Internet traffic from an organization, business or smaller Internet service provider to pass or “transit” through its network. When your organization procures an IP transit port, it will not only have access to the Internet but it can also allow others to access the Internet through the organization’s network. Furthermore, your organization will have access to the provider’s network and the networks of provider’s peers and other IP transit clients.

Who can get IP transit service?

Unlike dedicated Internet access where anyone can sign up with an Internet service provider, an organization requires an Autonomous System Number (ASN) to procure IP transit service.  An ASN identifies a network on the Internet and defines a group of routing prefixes that maintains a unique routing policy for the network. Every network on the Internet has an ASN and an associated block of IP addresses assigned by the Internet Assigned Numbers Authority (IANA). Any organization wishing to offer Internet access to its employees, members or customers may be granted Autonomous System status and a block of IP addresses after providing a justification of how the IP addresses will be used. Because there is a finite number of IP addresses (IPv4 and IPv6) available, the authority ensures that they are used efficiently. ASNs can be requested from regional authorities (given below) or through the upstream provider.

The following organizations typically buy IP transit:

  • Government research agencies and national laboratories
  • National educational and research networks (NRENs)
  • Universities and other educational institutions
  • Government departments
  • Business organizations of all sizes
  • Internet service providers (Tier 2 and Tier 3)
  • Hotel chains

Where to apply for an ASN and IP address blocks?

Organizations wishing to apply for autonomous system status and IP address blocks for their networks should contact the relevant authority in their region:

  • In Africa contact the Regional Internet Registry for Africa (AFRINIC)
  • In Asia pacific contact Asia Pacific Network Information Center (APNIC)
  • In Europe contact Réseaux IP Européens (RIPE)
  • In India contact Indian Registry for Internet Names and Numbers (IRINN):
  • In Latin America and the Caribbeans contact Latin America and the Caribbean Network Information Center (LACNIC):
  • In North America contact the American Registry for Internet Numbers (ARIN):

 

IP address allocation

Blocks of IP addresses are allocated by the regional authorities given above. An IP address block is divided into two parts, a part identifying the network on the Internet and a prefix that defines the size of the block. If an IPv4 block is presented as “192.168.2.0/26”, for example, “192.168.2.0” identifies the network and “26” is the number of bits in the network. Since IPv4 is 32 bit, only 4 bits (32-26 bits) are available for IP addresses. Thus, this is a small block with a total of 16 IP addresses. If the block was “192.168.2.0/2”, then there will be 30 bits available for IP addresses translating to 1,073,741,824 IP addresses – a very large block indeed. The smaller the number after “/”, the larger the block and vice versa. The block size alone is simply given as “/n”, where n is the number of bits in the network. The charts below, the so called Classless Inter-Domain Routing (CIDR) Charts, give more details for both IPv4 and IPv6 blocks.

IP transit pricing

There are two cost components in IP transit procurement – the provider service charge and the ASN and IP addresses charge. The provider’s charge will include a one-time installation charge and a Monthly Recurring Charge (MRC). The MRC may be fixed for an agreed upon data rate, also known as the committed data rate, and is payable even if the actual bandwidth usage is lower. However, if usage goes over the committed data rate, additional charges will be due. Alternatively, the MRC can also be made to vary with bandwidth usage – a model most suited for organizations with low bandwidth requirements. Most providers price their service per unit of bandwidth such as cost per Megabit/s. The higher the bandwidth subscribed to and the longer the contract term, the lower the cost per unit. For example, a company that subscribes to a committed data rate of 10Gigabit/s with a contact term of 5 years will be charged significantly less per Megabit/s than one that subscribes to 10Mbit/s with a contract term of 1 year.

ASNs and IP addresses can be obtained directly from regional registries for Internet numbers – American Registry of Internet Numbers (ARIN) in the case of North America. Some IP transit providers may be able to offer IP addresses to their clients. Contractual terms may vary depending on how your organization is classified – end user for organizations that need IP addresses for internal use and Internet Service Provider (ISP) for organizations that need IP addresses for distribution to external clients. ASNs and IP addresses also have two cost components – an upfront cost depending on the IP address block size and an annual maintenance cost. In North America upfront costs range from $250 for /24 IPv4 (/40 IPv6) block or smaller to $256,000 for /6 IPv4 (/4 IPv6) or larger.  In addition to the fixed charges, maintenance fees of $150 for any ASN, $150 for any IPv4 address block, and $150 for any IPv6 address block are payable annually.

IP transit features

If you request a quotation from multiple providers based only on the bandwidth, it is more than likely that you will receive you will receive a wide range of prices. The temptation for many small organizations is to jump on the least cost solution without paying attention to the features responsible for the cost disparity. It is strongly recommended that you review some of the important IP transit features to make an apple to apple comparison of pricing from different providers. Moreover, you have to carefully match your business requirements with what each provider is offering. Following are the most common features of IP transit services.

Contract terms

Most, if not all, IP transit providers require that you commit to a contract term, typically 1 to 3 years. Some may even offer terms of up to 5 years. You have to carefully weigh the pros and cons for your organization before settling for a contract term. You may contact FiberGuide to help review your service and offer guidance on the most suitable term. The longer the term, the lower the MRC and your monthly charge may be locked in to a fixed price, protecting you against any potential future price increases. On the other hand, if the service does not turn out to be what you expected, it will cost you to get out of the contract. It is advisable to start with a one year contract term and then extend to a longer term if you are happy with the service.

IP transit bandwidth scalability

New organizations, especially ISPs, prefer to start small and increase their bandwidth as their own clientele grows. Scalability is the ability of the network bandwidth to be increased by small amounts without significant changes to the infrastructure. Ethernet, for example, is more scalable than SONET or SDH.

Common IP transit interfaces

network-interfaceMost IP transit providers offer a wide range of interfaces to connect your network to theirs. The onus is on you to opt for the most suitable interface that meets your organization’s requirements. Unless there is a compelling reason for opting for a TDM based interface, such as existing TDM network, conventional wisdom is to opt for an Ethernet based interface. In addition to its ubiquity, Ethernet is flexible and is easily scalable. You can start with lower bandwidth such a 20 Megabit/s and be able to upgrade to 10 Gigabit/s without significant changes in infrastructure. Moreover, the industry is trending towards Ethernet and TDM may soon be obsolete. The following interfaces are readily available from most providers:

  • TDM (T1/E1, DS3/E3, OC-X/STM-N)
  • Fast Ethernet (up to 10 Megabit/s)
  • Gigabit Ethernet
  • 10 Gigabit Ethernet
  • 40 Gigabit Ethernet
  • 100 Gigabit Ethernet

 

IPv4 and IPv6 dual stack

The ever expansion of the Internet has resulted in IPv4 addresses running out. IPv4 is 32 bit with a total of about 4 billion addresses which can no longer meet the demand. IPv6 was introduced to provide sufficient addresses so that we can never run out of IP addresses again – at least not in the foreseeable future. IPv6 is 128 bit which translates to hundreds of trillions of possible IP addresses. However, until the whole Internet completely shifts to using IPv6, IPv4 and IPv6 have to co-exist. A dual stack network is one in which all the nodes are both IPv4 and IPv6 compatible.

Service Level Agreement (SLA)

Service level agreement the commitment that the IP transit provider makes to their client about the service. It includes that compensation promised by the provider in the event that certain aspect of the agreement are not adhered to. For example, if there is a downtime greater than that specified in the SLA, the provider may waive part of the MRC. Quality of service is one of the most important component of a SLA and it may include, among other attributes, availability, latency, jitter and packet loss.

Availability

Availability is the probability that the network will be up and running at any given time. Availability is specified as a percentage of the time that the network is up and running over a period of time.  A 99.5% availability translates to a total network downtime of about 2 days in a year. A 99.9999999% (9 9s) availability translates only to about 32 milliseconds of downtime in a year. However, for IP transit providers typically offer 99.9% to 99.999% availability and only a few can achieve the upper limit.

Latency

Latency (typically in ms) defines the time taken by a data packet to travel from the sender to the receiver.  It depends on the distance travelled, the transmission medium and the equipment (such as routers) through which the packets travel. If the medium is optical fiber then there is a 4.90microsecond/km (0.0094milliseconds/km) contribution to latency which can add up significantly if packets have to be routed through too many hops. If geosynchronous satellite systems are part of the IP transit network, then there is at least 540 milliseconds contribution from the data packet round-trip to and from the satellite. Certain applications such as videoconferencing, VoIP, gaming and high frequency trading are very prone to latency. In VoIP, for example, latency manifests itself as a delay between the time you talk in a handset and the time you hear a response from the called part. In a VoIP conversation, latency starts to be noticeable at about 250ms and it starts to get irritating at 300ms. At 500ms it becomes a total nuisance.

Jitter

Jitter occurs when latency changes with time. With a fixed latency, two parties to a conversation can come to terms with the delay between them and eventually have a smooth conversation. With jitter, however, the latency changes randomly over time, making it difficult to communicate.

Packet loss

The objective of any network provider is to deliver 100% of data packets originating from a sender to a receiver. However, inevitable network errors will cause some packets to be lost. Packet loss is defined as the percentage of the number of packets lost to the number of packets transmitted. Network technics such as forward error correction are used to compensate for the lost packets but this can come at a penalty in time – in other words packet loss slows the network. When packet loss is too high, it can manifest itself as a lost connection.

Tiers of Internet service providers | Tier 1, Tier 2, Tier 3

Tier 1 Internet providers.

The Internet is usually described as a giant network of networks connected to each other using the TCP/IP communication protocol. At the core of the Internet is a very high capacity optical backbone connecting continents and regions with submarine cable and terrestrial long haul cable respectively. The optical backbone is a network of the world’s largest networks (Tier 1 networks) seamlessly connected together into one network. The Tier 1 network providers peer with each other and allow IP traffic to flow from one network to another free of charge. A Tier 1 Internet provider can therefore be defined as one that connects to the Internet through unpaid peering. The peering arrangements between Tier 1 providers is also referred to as settlement free inter-connection. There are only about a dozen Tier 1 network providers, although there are many more that may claim to be Tier 1. If they don’t access the Internet by peering ONLY then they are not a Tier 1 provider in the strict definition of the term.  Level3 (now CenturyLink), AT&T, Verizon, Cogent, Global Telecom and Technology (GTT), Telia Carrier, NTT Communications, Tata Communications and Telecom Italia Sparkle are some of the Tier 1 providers.

The following is true of all Tier 1 Internet providers:

  • They only connect to the Internet by peering with other Tier 1 providers – they don’t pay for transit
  • They have access to the entire Internet routing tables through their peering arrangements
  • They peer on more than one continent
  • They own or lease submarine fiber optic capacity

AT&T
Headquartered in the USA, AT&T (American Telephone and Telegraph Company) boasts of one of the largest global backbone fiber optic network.  The network transport about 5 petabytes (that is 5 million Gigabytes!) of data on any given business day. The backbone network consists of over 500, 000 route miles.

CenturyLink (includes Level 3)
CenturyLink is an American company and is the second largest provider of networking solutions to businesses. Centurylink’s global Tier 1 IP network is over 500,000 route miles. The backbone has a capacity of 20.9 Tbps and they can offer 100 Gbps bandwidth per optical wavelength. CenturyLink has more than 40,000 on-net buildings (and growing) from which clients can easily access IP transit and other connectivity solutions.

NTT Communications
Based in Japan, NTT (Nippon Telegraph and Telephone) is one of the 5 largest global IP network providers. NTT has 2.5 Terabits of private peering with other Tier 1 network providers and has points of presence (PoP) in 190 countries.

Tata Communications
Tata communications (formerly VSNL) is an Indian based Tier1 network provider. Its backbone network consists of 500,000 km of submarine optical fiber, 210, 000km of terrestrial optical fiber, and 600 PoPs in more than 200 countries.

Telia Carrier
Telia Carrier (formerly TeliaSonera) is a leading global IP network provider based in Sweden. In May 2019, Dyn ranked Telia Carrier the number 1 Internet backbone in the world. Telia Carrier has more than 265 PoPs serving IP customers in more than 110 countries. Their IP backbone network is 65,000 fiber km covering North America, Europe, Asia and the Middle East.

Verizon Enterprise Solutions
Verizon, an American company, operates an expansive network to deliver IP services all over the world. The 500, 000 route km network traverses 150 countries in six continents. Verizon is one of a few network providers that owns both IP and analog voice infrastructure in many locations around the world.

Zayo Group
Zayo Group owns and operates a 130,000 route mile network (translates to 12.5 Million miles of optical fiber) in North America and Europe. The network includes connectivity to thousands of data centers, carrier exchange points, financial exchanges and other enterprise locations.

The following is true of all tier 1 Internet providers:

  • They only connect to the Internet by peering with other Tier 1 providers – they don’t pay for transit
  • They have access to the entire Internet routing tables through their peering arrangements
  • They peer on more than one continent
  • They own or lease submarine fiber optic capacity

 

Tier 2 Internet providers.

Tier 2 providers peer with other Tier 2 providers and, in addition, buy IP transit from Tier providers. Tier 2 providers include large Internet service providers such as incumbent and competitive local carriers. They include Comcast, Google Fiber, Liquid Telecom Zimbabwe and British Telecom.

Tier 3 Internet providers.

Tier 3 providers connect to the Internet exclusively by buying transit from Tier 2 or Tier 1 providers. They consist of small Internet service providers, enterprises and institutions.
