The Avaya Virtual Services Platform 4000 Series (VSP 4000) are products that, in computer networking terms, are standalone Switch/Routers (Layer 2/Layer 3) designed and manufactured by Avaya for Ethernet-based networks. The VSP 4000 hardware is a derivative of the earlier Ethernet Routing Switch 4000 Series, leveraging certain shared components, but implementing a new, completely different, operating system derived from the Virtual Service Platform 9000 Series. The role of the VSP 4000 is to extend Fabric-based network virtualization services to smaller, remote locations, thereby creating a single service delivery network.

The VSP 4000 offers a range of network virtualization services that are based on Avaya's extended implementation of Shortest Path Bridging; marketed as the 'Avaya VENA Fabric Connect' technology. The first software release supports:

  • Layer 2 Virtualized Services that extend VLANs across the Fabric (including across subnets and long distances)
  • Layer 3 Virtualized Services that interconnect and extend VRFs across the Fabric
  • Native routing between Layer 2 and Layer 3 Virtualized Services for access to shared services
  • IP Shortcut Routing that enables direct Layer 3 connectivity between individual end-points without requiring deployment of an additional IGP (e.g. OSPF).

These capabilities are positioned are supporting the following deployment scenarios:

  • Virtualized small and mid-sized Enterprise
  • Distributed Enterprise

Deployments would be made to facilitate the following business situations:

  • End-to-end traffic separation for multi-tenancy or for security / regulatory compliance (i.e. PCI DSS)
  • Integrated video surveillance


The first VSP 4000 models were made available in April 2013.[1] [2] [3] [4] The first models delivered in the series were:

  • VSP 4850GTS, a 1RU Layer 2/Layer 3 Switch that is equipped with 48 x 10/100/1000BASE-T ports (including two common Uplink ports offering SFP connectivity) plus 2 x 10 Gigabit Ethernet ports that feature SFP+ physical connectivity.
  • VSP 4850GTS-PWR+, a similar product the VSP 4850GTS, with the addition of supporting 802.3at Power-over-Ethernet Plus (PoE+) on the copper ports.
  • VSP 4850GTS-DC, a similar product the VSP 4850GTS, but with DC power instead of AC.

In June 2014, a further model was added:

  • VSP 4450GSX-PWR+, a 1RU Layer 2/Layer 3 Switch that is equipped with 36 x 1000BASE-SFP ports, 12 x 10/100/1000BASE-T ports that support 802.3at PoE+, plus 2 x 10GBASE-SFP+ Ethernet ports (that also support Gigabit SFPs).[5]
