The document discusses optical interconnect technology for routers. It describes how conventional copper interconnects have limitations like power consumption and distance, while optical interconnects using fibers can transfer data over longer distances with lower power. The D-chip is presented as the first commercial router product using optical interconnect between silicon chips. It provides over 1 terabit per second bandwidth density and can scale to support future networking needs. The document also outlines how an output queued router architecture using optical interconnects between line cards improves performance for multicast traffic compared to a conventional router design.
The document discusses Unified Networking Lab (UNetLab), a network emulation platform that allows for multi-hypervisor support within a single virtual machine. UNetLab can be run on VMware Workstation, ESXi, or Linux and supports emulation of routers, switches, firewalls, and other network devices from vendors like Cisco, Juniper, F5, Checkpoint and more. It provides web-based lab design and management, active topology diagrams, remote access to nodes, and other benefits for network simulation and training. Future plans include additional configuration and design capabilities.

This document contains a list of 13 references to technical documents related to networking protocols such as spanning tree protocol, multiple instance spanning tree protocol, per VLAN spanning tree protocol, Flexlink, and TRILL. The references provide documentation on configuration guides, design guides, and blog posts about these protocols from Cisco, H3C, and other networking organizations.
This document discusses programmable packet processing using P4. It begins with an agenda and overview of bringing the data plane back under programmatic control. It then discusses the benefits of a programmable pipeline and P4. The document introduces the Protocol Independent Switch Architecture (PISA) model and how P4 programs can define parsers, headers, metadata, tables, actions and controls to process packets. It provides examples of P4 code definitions and capabilities like counters and virtual routing/forwarding tables.
This document discusses programmable networking and the future of networking. It provides an overview of programmable switches and how they differ from traditional fixed-function switches. Programmable switches use a domain-specific compiler called P4 to program the forwarding plane and define protocols, packet parsing, and processing pipelines. This allows the behavior of the switch to be defined through software rather than being fixed in hardware. The document demonstrates how P4 programs map to the Programmable Switch Architecture (PISA) and provides examples of simple and complex data plane programs. It also previews some demonstrations of in-band network telemetry and traffic monitoring capabilities enabled by programmable switches.
This document provides an overview of various cybersecurity topics including the Shadow Brokers, next generation firewalls from Sourcefire/Cisco, security information and event management (SIEM) systems, Microsoft Active Threat Analytics (MS ATA), and security operations centers (SOCs). It discusses specific products like FirePower, Firepower Threat Defense, and features of SIEM architecture like routing and replaying event trails. The document also outlines attack timelines and methods used by MS ATA like brute force and pass-the-ticket attacks as well as remote code execution.
The document discusses a new router architecture called Compass-EOS that uses optical interconnects between silicon chips instead of electrical interconnects. This improves bandwidth density, reduces power consumption, and eliminates the need for an internal switch fabric. The architecture provides true output queueing across all line cards for better quality of service, multicast scaling, and system behavior. It also improves security by giving full visibility of all traffic to each egress port.
