How deep is your buffer – Demystifying buffers and application performanceCumulus Networks
Packet buffer memory is among the oldest topics in networking, and yet it never seems to fade in popularity. Starting from the days of buffers sized by the bandwidth delay product to what is now called "buffer bloat", from the days of 10Mbps to 100Gbps, the discussion around how deep should the buffers be never ceases to evoke opinionated responses.
In this webinar we will be joined by JR Rivers, co-founder and CTO of Cumulus Networks, a man who has designed many ultra-successful switching chips, switch products, and compute platforms, to discuss the innards of buffering. This webinar will cover data path theory, tools to evaluate network data path behavior, and the configuration variations that affect application visible outcomes.

In this session from the London AWS Summit 2015 Tech Track Replay, AWS Solutions Architect Steve Seymour dives deep into the Amazon Virtual Private Cloud service, covering features as well as best practices.
Amazon Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the Amazon Web Services (AWS) Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways.
The document discusses various techniques that internet service providers can use to prevent IP reflection attacks, including:
- Implementing BCP38 and BCP140, which involve validating the source IP address of incoming packets to prevent spoofing. This is recommended to be deployed as close to the edge of the network as possible.
- Enforcing validation using access control lists (ACLs) to filter packets and unicast reverse path forwarding (uRPF) to check the return path of source IP addresses. Strict uRPF is recommended for customers.
- Example ACL and uRPF configurations are provided for Cisco and Juniper routers to filter traffic from customer networks connected to the ISP edge router.
AWS re:Invent 2016: NextGen Networking: New Capabilities for Amazon’s Virtual...Amazon Web Services
Amazon’s Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the Amazon Web Services (AWS) cloud and gives you complete control over your virtual networking environment. Amazon VPC continues to evolve with new capabilities and enhancements. These features give you increasingly greater isolation, control, and visibility at the all-important networking layer. In this session, we review some of the latest changes, discuss their value, and describe their use cases.
Kubernetes networking can be complex to scale due to issues like growing iptables rules, but newer solutions are helping. Pod networking uses CNI plugins like flannel or Calico to assign each pod an IP and allow communication. Service networking uses kube-proxy and iptables or IPVS for load balancing to pods. DNS is used to resolve service names to IPs. While Kubernetes networking brings flexibility, operators must learn the nuances of their specific CNI plugin and issues can arise, but the ecosystem adapts quickly to new needs and changes don't impact all workloads.

This document outlines the steps to configure HSRP (Hot Standby Router Protocol) on two multi-layer switches (MLS1 and MLS2) including: configuring IP addresses, EIGRP routing, web server and NTP server, setting MLS1 as the active router, tracking the state of interfaces, using HSRP for load balancing between the routers, and enabling NAT on the border router for internal traffic.
The document provides instructions for a lab on route redistribution between OSPF, EIGRP and RIP routing protocols. It involves configuring the routing protocols on various routers as specified in the topology, including redistributing routes between protocols. It also requires summarizing loopback routes between areas and protocols.
The document describes tasks for configuring a zone-based firewall on Router 1:
1. Create an inside and outside zone on Router 1's interfaces; apply an inspect policy between the zones to allow necessary traffic.
2. Configure R2 to ping R3 by name by adding DNS and host entries.
3. Configure R2 to copy a file from R4's HTTP server using the file path and name.
4. Configure R2 as the NTP server and have the other routers synchronize to it after applying necessary firewall policies.
The document describes tasks to configure NAT on routers R1 and R2. This includes dynamically NATing internal networks and loopbacks to external IP ranges, PAT for some internal networks, and static NAT for R7's loopbacks. EIGRP is configured internally with redistribution. Access-lists are used to define the NAT source addresses and pools are used to map them to external IP ranges. Connectivity to external sites is tested with ping.
1. The document describes tasks for configuring a role-based CLI, including configuring IP addresses, routing protocols, VPN tunnels, and access privileges for different devices.
2. It provides configuration steps for R2 and R3 to enable PAT for inside networks and configure a site-to-site VPN between them with IPsec.
3. PC5 is given full access to R13 but can only use show commands on R14, while PC4 is limited to the show history command on R11.
1. The document describes tasks for configuring OSPF routing on a network topology.
2. Key configurations include enabling OSPF on each router, configuring authentication for Area 1, summarizing loopback routes on R4, and preventing Area 3 routers from receiving routes from other areas.
3. PAT is configured on routers R1 and R11 to allow traffic from multiple private networks to use a single public IP address.
The document provides instructions for configuring IPv6 on a network topology. It includes tasks to configure IPv6 addresses on routers, configure Frame-Relay over IPv6, assign IPv6 addresses to routers through autoconfiguration, and configure OSPF routing between the routers.
The document provides the configuration steps to complete an IPv6 lab topology including:
1. Configure routing protocols EIGRP, OSPF, and RIP on each router as specified in the topology.
2. Enable tunneling between IPv6 and IPv4 interfaces to allow communication across the different address families.
3. Configure specific routing protocols over the tunnels, including EIGRP 111 between R4 and R5 and RIP between R2 and R6.
4. Redistribute routes between protocols to ensure all routers receive routes from each other protocol.
Kerberos is a computer network authentication protocol which works on the basis of 'tickets' to allow
nodes communicating over a non-secure network to prove their identity to one another in a secure
manner. Its designers aimed it primarily at a client–server model and it provides mutual
authentication—both the user and the server verify each other's identity. Kerberos protocol messages
are protected against eavesdropping and replay attacks.
RADIUS uses UDP for authentication and authorization, encrypting only the password field, while TACACS+ uses TCP and encrypts the entire payload. TACACS+ separates authentication, authorization, and accounting functions, allowing for different authentication mechanisms to be used, while RADIUS combines these steps. TACACS+ supports additional network protocols and provides more granular control over authorized commands.
Terminal Access Controller Access-Control System (TACACS, usually pronounced like tack-axe) refers to a
family of related protocols handling remote authentication and related services for networked access
control through a centralized server. The original TACACS protocol, which dates back to 1984, was used
for communicating with an authentication server, common in older UNIX networks;
RADIUS is a protocol for carrying information related to authentication, authorization, and configuration
between a Network Access Server that desires to authenticate its links and a shared Authentication
Server.
RADIUS stands for Remote Authentication Dial In User Service.
RADIUS is an AAA protocol for applications such as Network Access or IP Mobility
It works in both situations, Local and Mobile.
It uses Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol
(CHAP), or Extensible Authentication Protocol (EAP) protocols to authenticate users.
It look in text file, LDAP Servers, Database for authentication.
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
