A SONET STS-3c user network interface IC
Proceedings of the IEEE 1991 Custom Integrated Circuits Conference, 1991Co-Authors: T.j. Robe, K.a. WalshAbstract:The STS-3c user network interface IC transmits and receives a SONET (synchronous optical network) STS-3c signal at 155.52 Mb/s. In addition to payload insertion and recovery, this 1- mu m CMOS IC scrambles the serial STS-3c line signal, performs SONET payload pointer processing, and provides several error performance monitoring functions. Test results show successful performance at data rates of up to 300 Mb/s.

Highly integrated ATM/SONET user-network interface
Electronics Letters, 1991Co-Authors: G.r. Lalk, C.a. Johnston, L. Giuck, T.c. Banwell, T.j. Robe, K.a. Walsh, K.c. YoungAbstract:The implementation of a highly integrated experimental research prototype ATM/SONET interface that operates at the SONET OC-3 rate of 155.52 Mbit/s is reported. The prototype interface provides various features of the physical (SONET) and asynchronous transfer mode (ATM) layers of the B-ISDN protocol reference model. This type of interface could be used in applications such as workstation interfaces in a switched ATM local area network or for the user-network interface in a broadband public network or customer premises network.

A SONET STS-3c user network interface integrated circuit
IEEE Journal on Selected Areas in Communications, 1991Co-Authors: T.j. Robe, K.a. WalshAbstract:Two different design implementation techniques were used to produce a functionally complex high performance synchronous optical network (SONET) synchronous transmission signal (STS)-3c (155.52 Mb/s) user network interface (UNI) chip in cost-effective 1 mu m CMOS technology. The CMOS chip functions as an STS-3c transmitter and receiver and can interface to the STS-3c line in either bit-serial or byte-parallel data format. The transmitter creates a SONET STS-3c frame structure including the necessary framing and control bytes. The receiver performs frame detection, several performance monitoring functions, and payload processor interpretation. In addition to SONET overheads, both the transmitter and receiver provide payload asynchronous transfer mode (ATM) mapping signals to the user. The user can choose between serial operation at 155.52 Mb/s or parallel operation at 19.44 Mbyte/s. Test results show that the experimental integrated circuit performs successfully at serial data rates of up to 300 Mb/s. >

Extensions to Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) for Error Notication in Generalized Multiprotocol Label Switching (GMPLS) user-network interface (UNI)
2013Co-Authors: George Swallow, Matt Hartley, Kenji Kumaki, Clarence Filsfils, Zafar AliAbstract:There are many scenarios in which extensions to Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) are required for error notication in Generalized Multiprotocol Label Switching (GMPLS) user- network interface (UNI). This document outlines these scenarios and specifies the required extensions to RSVP-TE. Although the GMPLS-UNI reference model is used to describe requirements and solutions in the document, the proposed extensions are equally applicable to other deployment scenarios such as inter-domain RSVP- TE.

Experimental demonstration of the enhanced optical user network interface (O-UNI) protocol
International Conference on Communication Technology Proceedings 2003. ICCT 2003., 2003Co-Authors: Wenhua Jiao, Yong Wang, Ludi ZhengAbstract:O-UNI is defined as the optical interface between the service provider (optical transport network) and user client equipment. We have built and demonstrated an O-UNI testbed between IPv6 routers through optical network in IPv6 Global Summit, May 2002. This testbed enhances UNI 1.0 with three features: TNA addressing and resolution, control plan recovery, and IPv6 support in both control and data plane. It is more robust and suitable for clients to access to the optical networks.
