Traffic News & Updates

The Internet is growing at an amazing rate (see Internet Software Consortium Internet Domain Survey), and WPI's consumption of bandwidth to the Internet is growing as well. WPI's external connections are made at the Goddard gigaPoP on Main Street in Worcester.

Currently, WPI has a connection to Internet2, an academic research network. The available Internet2 bandwidth is up to a gigabit per second. For commodity Internet, we have a connection to Cogent at 500 megabits per second over a gigabit link, to Charter at 10 megabits per second over a gigabit link, and to Level3 at 40 megabits per second, carried over a small portion of the gigabit Internet2 link.

July 20, 2012
This spring, the commodity service over the gigabit Ethernet link to Charter was increased to 500 megabits. The gigabit link to Cogent remains at 500 megabits, for a total service of 1 gigabit. Should either link fail the WPI community should not notice the loss, since these two high-speed connections give us redundancy. The link to Boston University will be phased out, since it is not of a magnitude to give us redundancy and it is too small to balance traffic with the two 500 megabit feeds.
September 29, 2009
Boston University has switched their NoX Commodity Internet Service offering from Sprint to Level3. Since we subscribe to that service, we are now connected to Level3 insted of Sprint. The service remains at 40M.
February 4, 2009
WPI has connected to Cogent Communications at 474 Main. We have a Gigabit Ethernet connection to them over fiber and we are initially allocating 500M of Internet Service.
January 30, 2008
WPI has requested disconnection of the OC3 to 1 Summer Street in Boston, since we will be using the NEREN Gigabit Ethernet ring to connect to the NoX henceforth.
December 5, 2008
WPI has connected to a Gigabit Ethernet ring from NEREN, the New England Research and Engineering Network. NEREN operates a fiber optic ring which circles through Massachusetts, Connecticut, and Rhode Island. We have connected to the ring at our campus edge at 474 Main Street and at the NoX in Boston. We are using this Gigabit link instead of the former OC3 (155 megabit) link as our connection to Internet2, and its Commodity Peering Service. We are waiting for a replacement for a dead-on-arrival optical interface, after which we will have a redundant connection. Until then, we are only running on half the ring, but still at the gigabit data rate.
May 2008
WPI began using the Commodity Peering Service of Internet2. Internet2 has been peering with ISPs and key providers around the country to bring access to the commodity Internet to Internet2. This new service offers higher speed, lower latency connections to much of the Internet via our Internet2 connection. Formerly, the Internet2 connection only connected other Internet2 members, state education networks, and research facilities. This enables quicker access to Youtube, Google, and lots of other services.
November 28, 2007
The Sprint bandwidth was increased to 40 megabits. This has turned out to be a reliable and useful service.
October 1, 2006
A third Internet feed has been arranged via the NoX. The Tier 1 provider is Sprint. We are hoping that this enhances WPI's connection to the Internet and we will see how this balances with our other Internet links.
September 28, 2006
A discussion with Charter explains why our two Internet feeds are not as well-balanced as we had hoped. Although Charter has Level3 and AT&T as Tier 1 providers, they are only advertising WPI to the Internet over the Level3 connection. ProSpeed also uses Level3. It appears to us that most net traffic prefers to use ProSpeed, making the Charter link less useful than we had hoped. We are evaluating our options.
September 15, 2006
The ProSpeed Internet feed was raised to 40M
August 15, 2006
The ProSpeed Internet feed was raised to 30M from its low summer setting.
May 15, 2006
The ProSpeed Internet feed was lowered to 20M for the summer.
May 1, 2006
The Charter Internet feed was turned up at 30M. We will use this as a second feed to give us diversity and redundancey in our connection configuration. Although we had expected this link to turn up some months earlier, Charter had some difficulties increasing their bandwidth. Growth in home Internet subscriptions and our unusually large (for Charter) request for bandwidth caused them to delay.
January 31, 2006
Intellispace assets were purchased by ProSpeed. This new company will give us the same Internet service.
October 2005
Intellispace announces impending bankruptcy. Evaluating our options, we approached Charter Communications. Charter has AT&T and Level3 as Tier 1 providers. WPI has been peering with Charter for a few years in order to offer better connectivity to campus from Charter Cable home subscribers in the area. This direct connection avoids using the costly commodity Internet connections of both Charter and WPI for this traffic. This same fiber link will be used for the new commodity Internet service.
August 15, 2005
The bandwidth to Intellispace is raised to 50Mbps for the academic year.
May 15, 2005
The usual reduction of Internet bandwidth is arranged with Intellispace for the summer months.
October 15, 2004
WPI re-homed our Internet2 connection from a direct link to Abilene in New York to a link to the Northern Crossroads (NoX) gigaPoP in Boston.
August 20, 2004
Intellispace bandwidth raised to 50Mbps for the arrival of the students.
August 11, 2004
Peering arrangement with Charter Communications completed.
May 2004
Intellispace bandwidth set to 15Mbps for the summer.
September 16, 2003
E-xpedient link no longer operating.
September 2003
Intellispace bandwidth raised to 45Mbps for the arrival of the students.
May 2003
Intellispace bandwidth set to 15Mbps for the summer.
August 12, 2002
We have completed the connection to our new Internet provider, Intellispace, at 45Mbps.
July 1, 2002
The transfer of Yipes' Boston area network, including WPI's Internet link, was made to e-xpedient, completing their purchase of this portion of Yipes' assets.
May 2002
Yipes bandwidth changed to 15Mbps for the summer.
March 22, 2002
Yipes filed chapter 11 bankruptcy.
September 2001
Yipes bandwidth was changed to 50Mbps for the regular terms.
May 2001
Yipes bandwidth was changed to 15Mbps for the summer.
February 2001
Commodity Internet has been switched to Yipes.
December 2000
We plan to disconnect the Qwest DS3 in order to return the Internet2 connection to a full OC3, and the WPI commodity Internet will be handled by Yipes.
October 10, 2000
The OC3 feed from the Internet2 Abilene network was opened to the Goddard gigaPoP.
September 22, 2000
A DS3 feed of commodity Internet was initiated from Qwest to the Goddard gigaPoP. This feed was contained within an OC3 circuit. The T1 lines are no longer used.
September 2000
WPI signed with Yipes, a provider with a different model of offering Ethernet connection to the network instead of traditional telco data connections (i.e. T1, T3, OC3, etc.) This should offer us flexibility in changing data rates since the rate can be change by reprogramming the interface, not needing to wait for installation of telco equipment. Our initial rate of connection is projected to be 25 megabits. Yipes uses Qwest, as we do already, and also Level3 and UUNet, so we will have some redundancy of connection.
July 2000
The C&W T1 line was decomissioned, leaving 5 T1 lines. The expectation was to have a T3 by the beginning of term, but the installation was late.
November 16, 1999
Two more Qwest T1 lines were added. With the C&W line, the total was 6 T1 lines of commodity Internet.
April 20, 1999
Three T1 lines of Internet service from Qwest were installed and the campus Internet routing was moved to a Nortel router, which had more ports than the Cisco router we had been using. The C&W line will be moved to this router and we plan to drop GTE service. More connectivity from Qwest is planned to be added next year, as demand warrants.
August 1997
WPI increased its available Internet network bandwidth by adding a second T1 connection to MCI's POP in Charlton, MA. MCI merged with WorldCom and they were required to divest itself of its Internet so that the resulting corporation did not have overwhelming domination of the US Internet market. Cable and Wireless purchased the MCI's Internet network and have become our ISP as a result. At this point, WPI had two T1 lines supplying commodity Internet. In order to enable the connection to two providers, the CCC purchased and manages WPI's own network router. The CCC also had to upgrade the routing protocol to Border Gateway Protocol version 4 (BGP4). BGP4 protocol is required to load-balance between disparate Internet providers. BGP4 needs more memory and router compute power than the simpler, single provider, Routing Information Protocol (RIP) which was formerly used. BGP4 also required assignation of an Autonomous System Number (ASN) to WPI. ASNs are only assigned to ISPs and other organizations with multiple, disparate Internet links. Managing the router has given the CCC more flexibility in dealing with network problems and has provided the CCC with the means to collect statistics on WPI's usage without depending on the ISPs for usage statistics. Having two providers has allowed WPI to stay connected to the Internet through three network outages in the past six months. The CCC collected and ISP provided statistics are available by following the links at the top of this page.
First Connection
WPI's first Internet provider was NEARnet (the New England Academic and Research network), which was operated by BBN. BBN has been a pioneer in Internetworking, starting with their being the prime contractor for ARPANet, back in the '60's. WPI began with a 56K connection, and later upgraded to a T1 (1.55 million bits per second) connection to this provider. We averaged under 5% utilization of the T1 in December of 1992
