Black holes, from a network security perspective, are placed in the network where traffic is forwarded and dropped. When an attack has been detected, black-holing can be used to drop all attack traffic at the edge of an Internet service provider (ISP) network, based on either destination or source IP addresses. Remotely triggered black hole (RTBH) filtering is a technique that uses routing protocol updates to manipulate route tables at the network edge or anywhere else in the network to specifically drop undesirable traffic before it enters the service provider network.
New Firmware Now Available for Select Linksys E-Series Wireless Routers –IPV6 Ready Logo Phase 2 (Gold)
Okay Linksys E-Series router owners, we had some new firmware upgrades to
our popular E-Series products including: E1500, E2500, E3200 and E4200.
The IPV6 support will help your router work correctly when service providers
migrate their networks over to the new Internet protocol. Downloading this
firmware will make sure your router supports their networks. Also if you
download the new firmware your router can automatically detect if there is
IPv6 traffic on the Internet port. If there is, it will be able to route
that data between the Internet and the user’s local computers. Cool uh?!
If you haven’t downloaded the new firmware yet – check out what we’ve added,
enhanced and some of the things we fixed: Yea – it’s Linksys being committed
to giving you the best experience possible!

By Daniel Howard, CTO and SVP, Engineering of SCTE
As you know, the Society of Cable Telecommunications Engineers (SCTE) continues to strive to provide new and unique ways to both train and challenge the cable workforce and our members. Through our Chapters, we have been holding a very successful Olympic-style challenge for field-level employees that includes both hands-on skill assessments and knowledge-based contests, and this continues to be a big hit with our members and the industry. But one thing I kept hearing in meetings with cable executives, managers and at SCTE chapters was the need for SCTE to provide resources and involvement opportunities for the IP engineers and computer scientists in our workforce who manage an increasingly larger portion of the overall network.
I’m therefore proud and excited to announce the new SCTE IP Challenge that we developed in partnership with Cisco as a response to this need. This new interactive event was created to drive awareness of the importance of foundational IP knowledge among the cable workforce, and it is designed to promote the benefits of IP expertise in the cable industry, as well as leverage thought leadership around IPv6 in particular.

MPLS 2011 Conference in Washington D.C., is two weeks away; and we can anticipate a dynamic venue that commences with a Cloud Architecture tutorial to be presented by my Cisco colleagues Azhar Sayeed and Kapil Bakshi on Sunday October 16.
Monday, October 17
Cisco’s Clarence FilsFils will present Data Center Interconnect: Multi-Homing, Resiliency and Mobility; to be followed in the afternoon by my presentation on SP Cloud Computing: Services, Architecture and Standards Considerations and Cisco’s John Evan’s presentation on Application and Service Aware IP/MPLS Networking.
To end the day, I will chair a panel on the Role of MPLS and Ethernet Network Technologies as Enablers to Cloud Computing with the participation of outstanding individuals in the industry such as:
- SERGEI GERASIMTCHOUK, Facebook
- SCOTT WHYTE, Google

Today was the first day of Interop 2011 in Javits Center in New York City! The event runs until Friday, Oct. 7, with a full schedule. The show floor is open on Wednesday and Thursday with the Cisco booth highlighting a number of medianet technologies.
Performance monitor, which allows for the analysis of voice/video/data traffic on Catalyst 3000 series switches and ISRs (today) just via a software upgrade, will be shown. Additionally, the medianet booth will have a demonstration setup where the Catalyst 3000, using the IPSLA video operations feature, generates synthetic video traffic that stresses the network in the same way as a variety of video endpoints. In keeping with the IPv6 theme of Interop this year we’ll also have IPv6-enabled video endpoints. In fact, we’ll be showing IPv6 to IPv4 interoperability. Stop by and say hi! Read More »
