Additional services

CATNIX members enjoy a series of added value services:

Multicast

A multicast testbed began in 2000 with the participation of several CATNIX entities. Currently, there's a separated VLAN available for the participation of those members that ask for it, both in IPv4 and IPv6.

Up

IPv6

CATNIX infrastructure allows IPv6 traffic exchange and it has been actively used for IPv6 events such as the IPv6 Summit, included in the Internet Global Congress 2005, or for the World IPv6 Day and World IPv6 Launch Day. The first IPv6 exchanges were made in 2005.

Up

NTP Server

It has two NTP time servers with totally independent connections. Acting as a primary server there is a Meinberg M200, located at Itconic (CSUC-T). The second one, a Meinberg M300, is located at Campus Nord (CSUC-CN), and acts as a backup. Both servers are Stratum 0/1 and are synchronized with the satellites to which they have visibility at any moment (between 3 and 8).

Up

IXP-Watch Server

The IXP-Watch tool, initially created by Rob Lister, from LINX, is designed to monitor on layer 2 and detect potentially dangerous traffic that could affect the performance of the IX (broadcast traffic, non-IP traffic...).

This tool allows the members to know the purity of the traffic inside the exchange and identify strange patterns, usually caused by a misconfiguration on the equipment of one of the members.

Up

F-root Name Server

Since 2005 CATNIX has a F-root name server replica managed by the Internet Systems Consortium (ISC).

This server accepts both IPv4 and IPv6 queries and it allows not only to improve the quality of service in the response time for the DNS queries but also to increase the security, because it guarantees the service operation in case of DDoS attacks.

Up

Looking Glass

This tool, which is running since the creation of CATNIX, is used to send interactive queries to some of the routers ant it is very useful to follow up routing problems.

Up

Out-of-band Access

In order to access the equipment without using the regular interfaces, there's an out-of-band router available to CATNIX members since 2002.This service is especially useful in case of network or router problems, because it allows technicians to make a quick diagnosis.

The access is done in a secure way, exclusively with ssh and limited by IP.

Up

J-root server

J-root name server replica is available at CATNIX since the end of 2010, and VeriSign is in charge of its management. With this and other available replicas, response time to the DNS (Domain Name System)  queries is improved and security is increased, because the global impact in case of DDoS (Distributed Denial-of-Service) attacks is reduced.

Up

.com and .net replicas

HP DL360p Gen8 server, installed in 2015, provides .com and .net TLD (Top Level Domain) replicas. Having these and other replicas, response time to DNS (Domain Name Server) queries is improved, as well as security increases because the global impact in case of DDoS (Distributed Denial-of-Service) attacks is reduced.

Up

24x7

In order to guarantee the maximum availability and reliability in the access to the equipment and services of the Centre, we have at the disposal of our members a 24 h service to attend the incidences occurred out of our office hours.

Up

Speed Test

This tool is designed to measure the quality of the internet connection in an easy way for users, showing the upload and download speeds in megabits per second (Mbps) and the latency in milliseconds (ms). The software, widely spread around the world, has been developed by Ookla, a leader company in appications of bandwith and network diagnostics founded in 2006 in the USA.

Up

L-root Name Server

Since June 2012 CATNIX has at its disposal a new L-root name server mirror, managed by the Internet Corporation for Assigned Names and Numbers (ICANN). This new mirror, together with other available replicas, improves the response time to DNS queries and increases security because the service in case of distributed denial-of-service attack (DDoS) is guaranteed.

Up

K-root Name Server

Since August 2015, CATNIX hosts a replica of K-root name server, operated by RIPE. In addition to this K-root replica, CATNIX allocates replicas of 3 other root name servers: L-root name server, operated by the Internet Corporation for Assigned Names and Numbers (ICANN); F-root server, operated by the Internet Systems Consortium; and J, .com and .net root servers, operated by VeriSign. They improve DNS response times and increase security as they guarantee the service in case of Distributed Denial of Service Attacks (DDoS).

Up

RIPE RIS

RIPE RIS, collects and stores Internet routing data from several locations around the globe, being CATNIX one of them. RIPE Routing Information Service (RIS) is a useful tool to identify rounting modifications. It allows users to see and download historical data and follow-up those changes to solve routing problems, draw maps of connectivity, monitor prefixes, etc. Data, opened to the community, is also useful for academic research.

Up

Monitoring panel

The new monitoring panel has real time statistics of all these connections. Information regarding traffic between nodes –Campus Nord, Itconic and bitNAP–, and of each router port, is available through this panel showing online occupancy rates. Also, the panel can indeed check the operating status of the connection and the capacity of the link that is being used both for sent or received traffic.

Up

LISP DDT

The LISP DDT root (Locator/ID Separation Protocol Delegated Database Tree) aims at experimenting with a network architecture and set of protocols that implements a new semantic for IP addressing. Implemented in 2014, it is based on the separation of the current IP addresses in two namespace: the relatively static Endpoint Identifiers (EID), the 'who', and the Routing Locators (RLOC), the 'where'.

LISP DDT is a distributed and hierarchic database which embodies the delegation of authority to provide mappings from LISP Endpoint Identifiers (EIDs) to Routing Locators (RLOCs), in a quite similar way in how DNS servers work.

Up

M-Lab Pod

M-Lab platform includes tools to test network connection, quality and neutrality. One of the most outstanding tools included in M-Lab platform is the NDT Speed Test and Diagnosis. The Network Diagnosis Tool (NDT) provides information on the configuration and performance of the user network, it compiles the test results and records the user's IP address, upload and download speed, the header and the transmission control protocol (TCP) variables of the test. In addition to the NDT, M-Lab platform includes other tools such as the NPAD (Network Path & Application Diagnostics), Neubot, BISmark, Paris Traceroute, OONI, MobiPerf, Reverse Traceroute and SideStream.

M-Lab performs active measurements. This means that tests only run when people decide to run them. They do not passively monitor your connection. M-Lab hosted tests do not download or upload files to or from your device. Instead, tests measure the way in which the network responds to a synthetic stream of data that is generated by the individual test specifically for the purpose of measurement.
