By the end of October 2006, during preparation for SuperComputing 2006 participation, we

managed to connect a second 1 Gbps link between SPRACE and NAP of Brazil for experimental

purposes. Due to the success of these experiments, ANSP engineers decided to include a 2 X 1

Gbps link in the first upgrade of USP-NAP-Impsat connection.

USP ­ NAP of Brazil ­ Impsat connectivity improvement:

ANSP engineers are continuously working to provide enhanced connectivity to São Paulo public

and private Universities and Research Institutions. One of those recent enhancements is directly

related to SPRACE connectivity, as its main goal is to leverage existing bandwidth between USP

and ANSP core routers in Barueri. USP Computer Center is a very important peering point,

housing RNP and RedCLARA Points of Presence in São Paulo state and being connected with

several telecom carriers and backbone providers. ANSP project goal is to aggregate traffic

coming from different sources using WDM technology over the dark fiber pairs that connect USP

and NAP of Brazil in Barueri, and those that connect NAP of Brazil and Impsat data center in

Cotia. Although the core of ANSP network is located in Barueri, Impsat in Cotia has the access

point to AMPATH through LANautilus [2] (São Paulo­Miami optical cable provider) and thus

houses the gateway for the WHREN-LILA link, the Cisco ONS-15454 SDH MSPP. Barueri and

Cotia are two small cities bordering on São Paulo, considered part of the São Paulo metropolitan

area.

ANSP project intends to establish six bidirectional 1 Gbps channels between USP and NAP of

Brazil and four 1 Gbps channels between NAP of Brazil and Impsat. Figure 93 below shows the

available fiber pairs linking each site and their approximate lengths.

This project is already partially implemented, using compact, modular WDM systems provided

by MRV Communications Inc [3]. Since October 2006 there are four 1 Gbps links between USP

and NAP of Brazil. One of these lambdas is being used by SPRACE. Figure 94 shows a detailed

drawing of USP-NAP connection at the present time.
