Vendor Specifications vs Real World Performance

Did you ever purchased a HW and find out the Hard way that the box is not performing in your environment who it was described in the datasheets

Routers and Switches

  • can be measured and tested in the Lab
  • Packet sizes
  • L2 vs L3 traffic
  • watch out for all the features that will degrade the performance

ARP packets can consume a lot of CPU utilization? Miimon – NIC teaming in Linux

Firewalls

  • Real world traffic is different
  • single flow can effect the complete system
  • NGFW features

Virtual vs Physical Hardware

  • Limitations of the physical HW
  • Performance penalties and with virtualization

Google

Google is perhaps one of the biggest tools in a network engineer’s toolset. Google is invaluable in searching for solutions to a problem or issue or simply searching for the documentation or an example configuration.

We returned to record our sixth episode on Sunday May 22, 2016.

Discussion

This week we had the opportunity to speak with Roger Lapuh, Product Line Manager and Architect for Avaya.

Past

The history of Avaya Networking, Wellfleet and SynOptics merged to form Bay Networks back in 1994. Northern Telecom acquired Bay Networks in 1998 and renamed itself Nortel. In 2009 Avaya acquired Nortel’s Enterprise Voice and Data business units through a bankruptcy auction.

In 1997 Bay Networks acquired Rapid City which spawned the first layer 3 switch in the Accelar product line. The product line was renamed to Passport and would eventually be renamed to the Ethernet Routing Switch.

SMLT Story and development
Layer 3 extensions RSMLT //  VRRP BackUp Master

Present

The first ideas to Shortest Path Bridging (SPB), the  development of SPB and the challenges presented in its design. The standards process in IEEE 802.1aq, the first implementation in the Ethernet Routing Switch 8600.

Packet Pushers Show 44 – The Case For Shortest Path Bridging, with Paul Unbehagen and Peter Ashwood-Smith (Huawei).

Future

Distributed Virtual Routing (DVR) resolves the network tromboning between the Layer 2 fabric and Layer 3 gateways.

Port Mirroring over an SPB fabric creating a virtual tap network.

We have a large vibrant community using Avaya equipment over on the Network Infrastructure Forums, I would strongly urge you to stop by and see what’s going on.

Thanks again to Roger Lapuh for joining us!
