Introduction

Internet development and the quality of user connectivity depend on the existence of good communications infrastructure and proper connectivity between countries. In Latin America, there are still some deficiencies in this regard which result in many people experiencing high latencies in their connections. The main reason for these latencies is the lack of local interconnection between different network operators, which means that traffic between nearby countries must often use distant Internet exchange points, located in the United States or .

The deployment of various Internet exchange points (IXPs) has helped improve this situation, although the actual status of connectivity between countries and networks remains a mystery. To find answers to these unknowns, some time ago LACNIC created Simón1, a project that seeks to generate information by measuring latency levels between countries and in this way estimate traffic volumes.

To complement the information obtained by the Simón Project, this interconnection study will attempt to understand the current status of the connections between the countries of Latin America based on a different source of information, namely, the BGP routing tables registered and stored by global collectors. Methodology Objectives

This study seeks to analyze various characteristics of regional interconnection based on the processing of global BGP routing tables for the purpose of comparing the basic characteristics of route announcements in the region, deriving conclusions regarding operators’ behavior when publishing their prefixes, detecting locations where traffic is exchanged with the largest number of operators, determining the dominant upstream transit providers in each country, the average number of autonomous systems traversed by traffic flows and their impact on regional routing stability, among other factors.

Therefore, we determined a set of parameters that would allow us to compare the current status and evolution of the regional Internet with the following objectives:

● To understand the nature of the autonomous systems in each country, how many autonomous systems provide local transit service, and which are connected to the rest of the world. ● To obtain general data on regional routing tables, e.g., the number of announced prefixes, the average length of IPv4 and IPv6 prefixes, and the average length of AS paths. ● To obtain additional data that can help assess Internet development, including the number of IXPs. ● To obtain data on interconnection, both between different countries as well as within each country. Data Sources

Global BGP routing tables will be analyzed using RIPE NCC's RIS2 service. The Routing Information Service (RIS) collects and stores Internet routing information obtained from different parts of the world. This global network is comprised of Remote Route Collectors that are typically located at the IXPs.

4

These collectors store the information in the MRT format described in RFC 63963. Every 15 minute, each collector stores all the BGP packets that have been exchanged (updates), plus a dump of its routing tables every eight hours (RIBs).

RIPE currently has 20 collectors in operation:

● rrc00 in , the ● rrc01 in London, ● rrc04 in Geneva, ● rrc05 in Vienna, ● rrc06 in Otemachi, Japan ● rrc07 in Stockholm, ● rrc10 in Milan, ● rrc11 in New York, USA ● rrc12 in Frankfurt, ● rrc13 in Moscow, ● rrc14 in Palo Alto, USA ● rrc15 in São Paulo, ● rrc16 in Miami, USA ● rrc18 in Barcelona, ● rrc19 in Johannesburg, South Africa ● rrc20 in Zurich, Switzerland ● rrc21 in Paris, ● rrc22 in Bucharest, ● rrc23 in Singapore ● rrc24 in ,

For this study, we used the routing table dumps (RIBs) of collector rrc00. The data was processed with pyBGPStream4, a Python library to use CAIDA BGPStream's BGPReader5, which allows the data published by RIPE collectors to be processed simply and efficiently.

In addition to the routing tables, in order to conduct a study that considers the countries of Latin America, we need to map allocated number resources to the different countries. To do so, we will use the delegated-extended file. This record contains a daily updated report of the distribution of Internet number resources (IPv4 and IPv6 addresses, autonomous system numbers). Each Regional Registry generates a file in a standardized format defined by the Number Resource Organization (NRO)6 and these files are then consolidated to obtain a single file.

Finally, to determine which Internet Exchange Points (IXPs) operate in each country or territory, we will use the CAIDA Internet eXchange Points Dataset7, which uses PCH8 as its data source. Compared with other references such as IXPDB9, this source contains a smaller number of IXPs. At the moment, however, it is the only one that provides historical data and in an easy-to-obtain format.

Data Processing

Achieving our stated objectives requires defining how the autonomous systems in each country will be classified, and then processing our proposed data sources to obtain the desired parameters and indicators. The example below will allow us to establish this classification.

Figure 1: Representation of the BGP announcement of a route propagated between autonomous systems inside and outside a country or territory.

Figure 1 shows AS-1, which announces its prefixes via BGP to AS-2 which, in turn, propagates this announcement to the remaining autonomous systems. Here, it is important to classify the role they each play, which is why they have been represented using three different colors. AS-1 (orange) announces prefixes, therefore it will be classified as an origin AS within this country. The blue systems (AS-2, AS-3, AS-4) provide transit: they connect to AS-1 within the country's territory. Finally, AS-5 (red) also provides transit, yet it is located outside the country. This type of autonomous systems will be classified as upstream and they are the ones that provide connectivity to a country. The announcement may continue to propagate to other autonomous systems, but these paths are no longer relevant for the purpose of a local analysis within the country of the origin AS.

This information is obtained by processing the global routing tables stored and published by RIPE NCC collector rrc00. For each entry in the table, we are interested in the set of prefix/as-path pairs as follows:

Prefix1/length | AS-X … AS-3 AS-2 AS-1

We will analyze the AS path from right to left, as we want to determine the origin autonomous system and, from there, all other relevant systems as described in Figure 1.

6

However, in order to make sense of this information, we need to map each prefix and autonomous system to a country. To establish this link between resources and territories, we will use the delegated-extended statistics file published by the RIRs. Thus, each entry can be interpreted as follows: [Country of the prefix] | [Country of ASX] … [Country of AS-3] [Country of AS- 2] [Country of AS-1]

Now we can start filtering the routing table entries, leaving only those that correspond to prefixes registered in the countries of the LACNIC service region. The AS path must be analyzed from right to left. If the country of AS-1 matches the country of the prefix, it is a route we are interested in analyzing and AS-1 will be considered an origin autonomous system for that country. We must then analyze AS-2. If this AS also belongs to the same country, it is considered a transit AS. Next, we must analyze AS-3 using the same procedure we used for AS-2. If it belongs to another country, it is considered an upstream AS and it is no longer necessary to continue analyzing the AS path.

If we apply this logic to the example shown in Figure 1, we obtain the following result:

Prefix AS-X ... AS-5 AS-4 AS-3 AS-2 AS-1

Country 1 Country 2 Country 1 Country 1 Country 1 Country 1

Upstream Transit Origin

In other words, based on this entry contained in the routing table we analyzed, it is possible to establish that, for this particular country, AS-1 is an Origin AS; AS-2, AS-3 and AS-4 are Transit autonomous systems; and AS-5 is an Upstream AS.

Generated Datasets

All the data required to meet the stated objectives are stored in datasets, which opens up the possibility of conducting other, more in-depth studies or applying different approaches. Therefore, it was decided to develop a set of scripts that would process the data in stages, obtaining partial results before producing a final dataset with summary data, which, in turn, are the main source for this report.

Figure 2: Data sources and processing to obtain the desired information.

Figure 2 shows the data processing flow. The result is a set of datasets that contain routing information for the different countries of Latin America, i.e., a snapshot of routing information on a specific day. These datasets are as follows:

country-data-.csv Lists the ASNs for each country considering their classification (origin, transit or upstream) and separates them based on the IP protocol.

prefix-data-.csv

8

Specifies data for each prefix announced and registered at LACNIC, including the country and origin ASN as well as the number of routes and total hops.

as-data-.csv Records data for each AS in the region, as well as the prefixes they announce and their relationship with other autonomous systems.

country-summary-.csv Summarizes the information in country-data-.csv, specifying the number of autonomous systems by country according to their classification (origin, transit or upstream)

prefix-summary-.csv Groups the data included in prefix-data-.csv by country, which allows obtaining general data for each one, such as average prefix and AS path length, total number of prefixes announced, etc.

ixp-data-summary-.csv Specifies the number of Internet exchange points in each country.

country-routing-stats-.csv Groups the information in country-summary-.csv, prefix-summary-.csv and ixp-data-summary- .csv to obtain, for each country, a set of relevant data related to its Internet development.

The resulting data has all the necessary information, which we will now analyze in the following sections of this report.

Data by Country

In order to determine the interconnection status of each country or territory that is part of the LACNIC service region, we will show the most relevant data obtained during the processing stage. It is important to note that, because the data is calculated for a specific moment in time, in this case we used the data generated in July 2020 as representative of the year.

Only the countries that have been assigned sufficient resources to calculate the various indicators are listed below. Therefore, while Saint Eustatius (BQ), Curacao (CW), the (FK), South and the Sandwich Islands (GS), and (SX) are part of the LACNIC service region, they were not analyzed in this section.

Both rankings are dominated by autonomous systems in Europe and the United States. Only AS 52468 belongs to the region (it is registered in Panama).

61

Connection to the Other Regions

The processed data also allows us to determine to which other regions the countries of Latin America are connected and therefore assess whether local traffic exchange is adequate.

Figure 3: Flow of the prefixes announced outside each country.

62

Figure 3 shows how most of the prefixes registered with LACNIC are announced to the regions serviced by ARIN () and the RIPE NCC (Europe).

As for the other regions, it shows that only two countries —Brazil and Colombia— connect directly with AFRINIC (Africa). Likewise, seven countries — Brazil, Mexico, Argentina, Guatemala, Venezuela, Colombia and Ecuador— connect directly to APNIC ( Pacific).

Finally, while most of the countries have links with other countries in Latin America, the number of connected autonomous systems is considerably lower than for the case of ARIN and the RIPE NCC. This shows that the countries of our region are often fragmented and that there is little traffic between them. This probably translates into higher latency, as the connection between two Latin American users must often transit through links in the United States or Europe.

Instead of counting the number of announced prefixes, the same analysis can be made by processing the autonomous systems connected to other regions.

The same trend can be observed in Figures 3 and 4. In Figure 4, however, it is even more evident that Brazil dominates over all the other countries of the region. If we continue to analyze Brazil, we can see how the ARIN and the RIPE NCC service regions receive more than three times as many networks compared to AFRINIC, APNIC and LACNIC.

As Figure 4 shows, all the countries of Latin America except French Guiana (FR) have at least one AS connected to an AS in the ARIN region, while the only territories not directly connected to the RIPE NCC region are Suriname (SR), the Falkland Islands (FK) and Guyana (GY).

Conclusions and Future Work

An analysis of where the autonomous systems of each country connect when they leave their country shows that, generally speaking, less than a third of these autonomous systems connect directly with others in Latin America and the Caribbean. This is also evident in the fact that the autonomous systems that provide the largest transit capacity from the countries of the region to the rest of the world are registered either with ARIN or with the RIPE NCC. This involves certain problems. First, it discourages the implementation of highly interactive applications in the region, as latency is higher compared to connections with the United States or Europe. In addition, P2P applications consume large amounts of bandwidth in long-haul links instead of exchanging traffic locally at a lower cost. Finally, from a geopolitical perspective, in our region, connectivity depends heavily on countries of other regions.

All of the above presents an opportunity to generate new connections between peers and Internet exchange points, as well as potential investments by companies wishing to develop regional traffic business opportunities.

In addition, this study also allowed us to analyze data on the IPv4 and IPv6 prefixes that are being announced. The fragmentation of IPv4 prefixes, which can be observed in countries with an average prefix length closer to 24 bits, is probably the result of new operators who appeared in recent years during the final phase of IPv4 exhaustion. As for IPv6, the results of this study showed lower deployment rates than those determined by other studies10. However, it should be noted that the data processed in this report include only the prefixes announced and registered by collectors, not all the prefixes that have been registered. In addition, IPv4 prefixes have a much higher level of disaggregation.

As for the data source used for this study, we only used the rrc00 collector to obtain routing information, and this collector is located in Europe. This may have created a certain bias, increasing the proportion of connections to this continent compared to the others. In this sense, other datasets could be generated using more than one collector and selecting them taking into account regional diversity so as to verify that the number of connections not considered in this analysis was not significant.

Another source of data that might be reviewed is the Internet exchange point (IXP) registry, which currently uses data collected by CAIDA11 with PCH as its source. Because this study analyzes the region of Latin America and the Caribbean, this source might be replaced by data provided by LAC-IX, the Latin American and Caribbean Association of Internet Exchange Point Operators.

As for the work we propose for the future, the same data could be calculated taking this study as a reference and similar reports could be prepared for the other four Regional Internet Registries (AFRINIC, APNIC, ARIN and RIPE NCC). This would allow directly comparing the different regions. It would also be possible to perform calculations backwards in time and compare our current data with the status of our region five or ten years ago.

It is important to continue to conduct similar studies in order to assess Internet resilience and development in our region based on different sources of information. Just as this study used as its main source of data the routing tables provided by the RIPE NCC route collectors, traceroutes from locations across the continent might also be analyzed. This would require measurement devices and vantage points that allow performing this type of analyses.
