The critical questions are preceded by a "*". Equipment Name & Description: ATM Standards: 1) UNI Signalling: * a) Do you support all of the mandatory capabilities of ATM UNI Signalling, Version 4.0 (af-sig-0061.000)? * b) Do you support the Signalling ABR addendum (af-sig-0076.000)? (Needed because it allows parameterized QoS negotiation and better support for point-to-multipoint calls.) * c) Do you support all of the mandatory capabilities of ATM UNI 3.1? (Needed for NIC's since UNI Signalling 4.0 is not backwards compatible.) d) Do you support any optional features of the specification? 2) LAN Emulation Over ATM Version 2 - LANE v2: (LANEv2 provides a LAN emulation environment that is compatible with legacy networks. Unlike LANEv1 which UBR and had no QoS, LANEv2 provides for ABR and QoS and enhanced multicast support. Also LANEv2 is a requirement for MPOA.) * a) Do you support all of the Mandatory Features in LANE v2 (af-lane-0084.000)? * b) Which of the following optional features do you support? Quality of Service (in the LE Client)? Multicast Services (in the LE Client & LE Server)? Support for UNI SIG 4.0 (in the LE Client & LE Server)? c) What other LANEv2 features do you support? * d) How many LE Clients are supported per edge switch? e) How is Emulated LAN (ELAN) membership configured? What granularity is used for membership, e.g., by port number, MAC address, or network address? * f) Where are the LE Configuration Server (LECS), LE Server (LES), and Broadcast Unknown Server (BUS) implemented in hardware and software? g) If you provide redundancy for the LECS, LES and BUS, how is it implemented, and what features do you provide? * h) What is the maximum number of hosts allowed per ELAN? * i) What is the maximum number of ELANs per LES, LECS, and BUS? * j) What is the latency and cps rate for the BUS? 3) Private Network-Network Interface Specification Version 1.0 (PNNI 1.0) (PNNI provides scalable routing and signalling functions. These services allow switches to gather topology information and make source routing possible.) * a) Do you support all of the mandatory capabilities of PNNI 1.0 (af-pnni-0055.000)? * b) Which of the following optional features do you support? (af-pnni-0066.00, af-pnni-0075.000, af-pnni-0081.000) Alternate routing as a result of Crankback Switched Virtual Path (VP) Service Soft PVPC and PVCC support ABR Signalling for Point-to-point Calls Frame Discard ILMI over PNNI links c) What other PNNI 1.0 features do you support? d) What support do you have or plan to have for IPNNI? When? * e) What support do you have or plan to have for MPLS? When? 4) Integrated Local Management Interface (ILMI) 4.0 (ILMI specifies how SNMP and an ATM Interface MIB are used to provide status and configuration information to ATM devices regarding VPC, VCC, registered services and capabilities, network addresses and prefixes.) * a) Do you support ILMI 4.0 (af-ilmi-0065.000)? 5) Traffic Management 4.0 (Traffic management is used to protect the network and the end- system from congestion in order to achieve network performance objectives. It also is used to promote network resources. It is related to QoS.) a) Do you support Traffic Management 4.0 (af-tm-0056.00)? b) What traffic management functions do you provide and how? Connection Admission Control (CAC) Feedback controls Usage Parameter Control (UPC) Cell Loss Priority (CLP) Control Traffic shaping Network Resource Management Frame Discard ABR Flow Control c) What is the maximum buffering per port? 6) Multiprotocol Over ATM (MPOA) (MPOA reduces burden on routers by allowing SVC setup on long-lived data streams.) * a) Do you support MPOA (af-mpoa-0087.000)? * b) Do you support Next Hop Resolution Protocol (NHRP)? If so, what routers have you demonstrated that your products are interoperable with? 7) Multicast Support * a) How do you implement multicast support? b) Where do the support services reside? 8) PVC's, SVC's and SPVC's: a) What is your PVC support? b) What is your SVC support? c) Do you support Soft PVC's (SPVC's)? d) What is the maximum number of concurrent PVC's per port? per switch? e) What is the maximum number of concurrent SVC's per port? per switch? f) What is the maximum number of concurrent SPVC's per port? per switch? g) What is the SVC call set-up time? What is the maximum number of calls that can be set up in a second? (per port/switch?) * 9) Which of the following bit rates do you support: Available Bit Rate (ABR) Constant Bit Rate (CBR) Unspecified Bit Rate (UBR) Variable Bit Rate - Real Time (VBR-RT) Variable Bit Rate - Non-Real Time (VBR-NRT) * 10) Which ATM Adaptation Layers do you support? AAL-1 - CBR, time-dependent traffic like voice & video, connection-oriented. AAL-2 - VBR AAL-3/4 - VBR, delay tolerant traffic requiring some sequencing/ error detection support. connection-oriented & connection-less. AAL-5 - VBR, delay tolerant traffic requiring minimal sequencing/ error detection support, connection-oriented. 11) Edge Switch Specific Questions: a) Do you support the 802.1d spanning tree specification? * b) What is the packet throughput between legacy LANs consisting of the following: 100BaseT, 10BaseT, and FDDI? c) What filtering capabilities do you have? d) Does your equipment provide edge switch-to-edge switch communication without requiring intervening ATM switch? 12) Fault Tolerance: a) What fault tolerant features do you provide? b) Are any of the components hot-swappable without creating a disruption in service on the non-swapped components? 13) Performance: a) What is the maximum number of MAC addresses allowed per port? per switch? * b) What is the maximum aggregate backplane throughput? c) What is the maximum aggregate backplane throughput available for user data? 14) Configuration * a) What fixed configuration interfaces are present on the equipment? * b) How many expansion modules or modular slots are available in the unit? * c) What are the minimum and maximum number of interfaces supported in your equipment for the following technologies: 0C-12 ATM OC-3 ATM Gigabit Ethernet FDDI 100BaseTX 100BaseFX 10BaseT d) Traffic between 100Base or 10Base ethernet ports on the same module/ card is shared or switched? e) Traffic between 100Base or 10Base ethernet ports on different modules/ cards is shared or switched? f) Are any other modules/cards required to run? e.g. management cards? 15) Network Management (is there overlap with ILMI?) * a) What Network Management Software can be used to manage this equipment? * b) Does your equipment support the following?
