RSVP-TE Point to Multi-Point (P2MP) Emulation Software

Transcription

1 RSVP-TE Point to Multi-Point (P2MP) Emulation Software Ixia's IxNetwork RSVP-TE (Resource reservation Protocol with Traffic Engineering) P2MP (Point to Multi-Point) Emulation Software is designed to analyze the performance of Label Switching Routers (LSRs) that support MPLS Traffic Engineering (TE). When used in conjunction with a trafficengineering-enabled Interior Gateway Protocol (IGP) (such as OSPF-TE or IS-IS-TE) large and complex MPLS topologies can be emulated. The P2MP protocol wizard is specially designed for multi-dimensional scalability testing. Ixia's RSVP-TE P2MP Emulation Software can be easily configured to establish and maintain thousands of Label Switched Paths (LSPs) or Sub- LSPs on each Ixia test port, so as to stress the most powerful MPLScapable routers. Once LSPs and Sub-LSPs are generated MPLS traffic can be transmitted, at line-rate, and metrics such as packet loss and forwarding rates captured. RSVP-TE Fast Reroute is supported to test systems for traffic redirection upon failures. Easy-to-Use Interface The IxNetwork GUI facilitates the quick and easy configuration of routing protocol emulations. Configuration wizards provide a graphical-based, step-by-step process for the initial setup of small to large scale test topologies across multiple Ixia test ports. The RSVP-TE wizard significantly simplifies the setup of tunnels in complex RSVP-TE scenarios. It supports configuring both P2P and P2MP emulation in a single run to test a real-world router, which usually contains a mixture of P2P and P2MP LSPs. In addition, IxNetwork's spreadsheet GUI paradigm provides for the entry, editing and viewing of large configurations across multiple test ports. Spreadsheet-like commands are available to quickly scale a configuration or apply operations across multiple values. Once a network topology is created, it can be copied easily across any supported Ixia test port. RSVP-TE P2MP test environment Agoura Road Calabasas, CA USA Tel Document No.: Rev D November Page 1

2 Key Features Supports Root Node, Branch Node and Leaf Node emulation to test DUT/SUT in various configurations, on either a per-interface/port or per-sub-interface (VLAN) basis. Comprehensive wizard allows the user to setup both P2MP and P2P RSVP-TE configuration in single run. Moreover, it allows the user to set up complex P2MP testing scenarios with multiple neighbors on a single port and multiple IP head/tail ranges for one-to-one or fully mesh mapping. The wizard can simulate complex network topologies and easily generate large numbers of tunnels and S2L sub-lsps, which facilitates scalability and stress testing. The wizard offers the user configurable parameters to allow multi-dimensional scalability such as leaf nodes per neighbor, total neighbors, P2MP tunnels per ingress head/egress neighbor, total P2MP LSPs within a tunnel, and the number of head nodes. Fully support ERO, SERO, RRO and SRRO objects. Support of Srefresh and adding/deleting S2L Sub-LSP (grafting) operations. Support of non-aggregate mode (sending PATH for individual S2L Sub-LSP instead of the entire P2MP Sub- LSPs). Support Fast ReRoute P2MP LSPs. Full Tcl API support for test automation. Port level consolidated learned information and filtering is available to aid in troubleshooting. User friendly traffic wizard allowing automatic label binding for S2L traffic, and more importantly allowing each leaf node to track per-flow statistics on a per-port or per-vlan basis. Support of all new objects as defined by RFC 4875, with IPv6 variants for full negative testing from the traffic editor. Configure large numbers of entries quickly with spreadsheet entry mode. Modify configuration entries while the state machine is running to simulate realistic network conditions. Customize by configuring detailed object parameters. Create Tcl configuration code simply by using ScriptGen. Analyze and track real-time MPLS traffic on a per-flow basis. Emulation Flexibility Ixia's RSVP-TE P2MP Emulation Software has the flexibility to emulate one or more root nodes and/or leaf nodes, and generate thousands of LSPs and Sub-LSPs on a single port. Many session and tunnel attributes are exposed, enabling users to create customized configurations. Both P2P and P2MP emulation can be run over exactly the same network topology to allow performance testing on a real world router. Users also have the flexibility to configure via Tcl commands. Protocol window configurations can be easily converted to Tcl commands with Ixia's ScriptGen utility. Scalability Hundreds of thousands of P2MP tunnels, LSP tunnels, or sub LSPs can be supported on an IXIA chassis populated with per-port CPU Load Modules. Multiple protocols can be run simultaneously in conjunction with linerate traffic. In addition, sessions and tunnels can be flapped to dynamically to assess how an MPLS router will behave under adverse network conditions. Page 2

3 Multi-Protocol Support Multiple protocols from Ixia's family of emulation software can be run simultaneously on one or many ports to simulate realistic network scenarios. Line rate MPLS traffic can be generated to advertised labels. Verify Next Generation Multicast VPN Networks IxNetwork provides a highly scalable and complete solution to verify Next Generation Multicast VPN (NG-mVPN) implementations and deployments. The RSVP-TE P2MP Emulation Software includes full support for creating multicast distribution trees (i.e. P-Tunnels) using P2MP LSPs as part of a simulated Multicast VPN topology. A dedicated Multicast VPN protocol wizard provides an integrated solution that can simulate large numbers of CE routers, PE routers and mvpn sites with simultaneous BGP, PIM, MPLS and IGP emulation. IxNetwork can completely surround the system under test and provide highly realistic, controllable and accurate testing. Tcl Support Automated scripts can be quickly created using the Tcl scripting environment. Alternatively, the IxNetwork GUI can be used to set up a test configuration, and then the Ixia's ScriptGen utility used to translate the GUI settings to Tcl code with minimal commands. Tcl support is available on Windows, Linux, and UNIX platforms.
