Axerra Networks, which develops what it calls Multiservice over Internet Protocol (MoIP) products, said it has completed interoperability testing with Cisco's Spatial Reuse Protocol (SRP). SRP is the basis for Cisco's Dynamic Packet Transport (DPT) technology, used to IP-optimize optical transport for metro networks.
This announcement shows "Axerra's commitment to work closely with Cisco to ensure solutions meet service providers' need for increased revenue by supporting both legacy and emerging services," officials said in a statement.
Axerra has completed extensive interoperability testing with Cisco's SRP metro products to allow service providers to deploy legacy services, including voice, leased-line, and frame relay, alongside IP services on packet-based metro networks. Axerra's patent-pending MoIP technology adapts these services to IP and delivers Quality of Service (QoS) enabled traffic flows to the provider's IP-optimized metro network, the company also said.
Powering Cisco's Metro IP systems, DPT utilizes two counter-rotating fiber rings that maximize the bandwidth available for data packet transport and by its design, facilitates data taking the shortest path to its destination. DPT is based on the Spatial Reuse Protocol (SRP), a Cisco-developed MAC-layer protocol for ring-based packet internetworking. Cisco has submitted SRP to the IEEE 802.17 Resilient Packet Ring (RPR) Working Group for consideration as the basis for the industry standard. Documentation is also available as IETF Informational RFC 2892.
Axerra Networks' AXN Multiservice IP Concentrators include hardware and software technology that enables telecom carriers to adapt all services for transport over a unified IP or IP/MPLS networks or Ethernet-based metro networks. The Axerra Networks line of AXN concentrators consist of carrier-class hardware and software solutions that perform aggregation, concentration, and service adaptation at the Multiservice network edge for traffic carried over next-generation IP and IP/MPLS networks. In addition, the entire product family offers flexible, fully channelized DS1/E1 and DS3/E3 customer facing interfaces, with GigE/FE and PoS OC-3/STM-1 and OC-12/STM-4 network uplinks.
