PTSE Rates in PNNI Networks
نویسندگان
چکیده
The Private Network Node Interface (PNNI), standardized by the ATM Forum (see [1]), provides a flexible and scaleable routing architecture for ATM networks comprising a routing protocol and a signaling protocol. In PNNI networks PTSEs are used to distribute topology information through the network. This paper investigates the PTSE rate in PNNI nodes due to flooding. Beside theoretical results, the paper also presents some measurements of example networks.

متن کاملA QoS-based routing algorithm for PNNI ATM networks
Although the ATM Forum has proposed the Private Network-Network Interface (PNNI) Specification to facilitate routing in ATM networks, path selection or routing algorithms that guarantee a user’s multiple Quality of Service (QoS) requirements remain an open issue since the PNNI protocol only provides a routing framework and does not standardize on a method of finding an appropriate path. In this...
