Diffserv

   Also found in: Acronyms, Wikipedia 0.03 sec.

Diffserv

(DIFFerentiated SERVices) A method for adding quality of service (QoS) to IP networks from the IETF. Operating at layer 3 only, Diffserv uses the IP type of service (TOS) field as the Diffserv byte (DS byte). Diffserv does not provide traffic engineering or hard quality of service similar to ATM. When MPLS is deployed within the network, Diffserv can be used at the edge for classification and assignment to the right connection. See MPLS.

Teja NP consists of an Application Development Environment, Network Processing Operating System (NPOS), and a library of foundation application building blocks including TCP Termination, IPv4 Forwarding, IPv6 Forwarding, NAT, DiffServ QoS, ATM and Security.
This benchmark adds DiffServ classification and marking beyond IPv4 forwarding as required by the NPF benchmark and therefore provides a more real-life environment and further strains network processor capabilities.
Other hardware-based key features such as advanced QoS, DiffServ, IP Multicast, and IP Filtering, provide consistent feature rich performance solutions for converged next generation enterprise network applications of voice, video distribution, distance learning and mission critical data applications.
