IP Infusion Application Note for 4G LTE Fixed Wireless AccessDhiman Chowdhury
SKY Brazil is one of the largest Pay TV provider in Brazil with 5Million+ subscribers created world’s first disaggregated 5G-ready Fixed Wireless Access (FWA) network using IPInfusion’s disaggregated Cell Site Gateway Solution to serve 35K broadband subscribers.
Learn how the deployment was done, read this application note to know more about the usecase and OcNOS configurations.
GLBP (Gateway Load Balancing Protocol) is a Cisco proprietary protocol that attempts to overcome the
limitations of existing redundant router protocols by adding basic load balancing functionality. GLBP is a
virtual gateway protocol similar to HSRP and VRRP.
However, unlike its little brothers, GLBP is capable of using multiple physical gateways at the same time.
As we know, a single HSRP or VRRP group represents one virtual gateway, with single virtual IP and MAC
addresses. Only one physical gateway in a standby/redundancy group is responsible for packet
forwarding, others remain inactive in standby/backup state.

Ether Channel High Speed Data TransmissionNetwax Lab
EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco
switches. It allows grouping of several physical Ethernet links to create one logical Ethernet link for the
purpose of providing fault-tolerance and high-speed links between switches, routers and servers. An
EtherChannel can be created from between two and eight active Fast, Gigabit or 10-Gigabit Ethernet
ports, with an additional one to eight inactive (failover) ports which become active as the other active
ports fail. EtherChannel is primarily used in the backbone network, but can also be used to connect end
user machines.
VRRP (Virtual Router Redundancy Protocol) is a computer networking protocol that provides for
automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the
availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.
The Virtual Router Redundancy Protocol (VRRP) eliminates the single point of failure inherent in the
static default routed environment. VRRP specifies an election protocol that dynamically assigns
responsibility for a virtual router (a VPN 3000 Series Concentrator cluster) to one of the VPN
Concentrators on a LAN. The VRRP VPN Concentrator that controls the IP address(es) associated with a
virtual router is called the Master, and forwards packets sent to those IP addresses.

The primary requirements for OpenStack based clouds (public, private or hybrid) is that they must be massively scalable and highly available. There are a number of interrelated concepts which make the understanding and implementation of HA complex. The potential for not implementing HA correctly would be disastrous.
This session was presented at the OpenStack Meetup in Boston Feb 2014. We discussed interrelated concepts as a basis for implementing HA and examples of HA for MySQL, Rabbit MQ and the OpenStack APIs primarily using Keepalived, VRRP and HAProxy which will reinforce the concepts and show how to connect the dots.
In this presentation, we will discuss how IEEE standard 802.3ad and its implications allow third-party devices such as switches, servers, or any other networking device that supports trunking to interoperate with the distributed trunking switches (DTSs) seamlessly.

CSC 451/551: Computer Networks Fall 2016
Project 4: Software Defined Networks
1 Introduction
In this assignment you will learn how to use the OpenFlow protocol to program an SDN controller in
a Mininet emulated network using POX. The following sections will first introduce you to the tools
you will need to complete the assignment, guide you on how to install and use then, and lastly outline
what you will have to do.
2 Software Definined Networks (SDN)
A Software Defined Network (SDN) is a network with a centralized controller that dictates the flow
of network traffic. Unlike convention networks where each individual router or switch decided how to
forward packets, in an SDN a centralized controller tells each router or switch how to forward packets.
In this assignment you will have to write your own SDN controller.
3 OpenFlow
OpenFlow proposes a way for researchers to run experimental protocols in the networks they use every
day. It is based on an Ethernet switch, with an internal flow-table, and a standardized interface to add
and remove flow entries. OpenFlow exploits the fact that most modern Ethernet switches and routers
contain flow-tables (typically built from TCAMs) that run at line-rate to implement firewalls, NAT,
QoS, and to collect statistics. An OpenFlow Switch consists of at least three parts:
a. a flow table, which keeps an entry for every flow and tells each switch how to process the flow.
b. a secure channel that connects the switch to a remote control process, namely the controller that
adds and removes flow entries from the flow table for different experiments allowing commands
and packets to be sent between a controller and the switch by using
c. a protocol, which provides an open and standard way for a controller to communicate with a
switch.
In the context of OpenFlow, a flow can be a TCP connection, or all packets from a particular MAC
address or IP address, or all packets with the same VLAN tag, or all packets from the same switch
port. Every flow entry in the flow table has 3 basic actions associated with it:
a. Forward the flows packets to a given port or ports, which means packets are to be routed through
the network.
b. Encapsulate and forward the flows packets to a controller, which either processes them or decides
if the flow needs to be added as a new entry to the flow table (i.e. if the packet is the first in a
new flow).
c. Drop the flows packets, which can be used for security issues, to curb denial-of-service attacks
and so on.
Read the OpenFlow whitepaper [1] and familiarize yourselves with the basic OpenFlow elements, before
continuing.

Build Real-Time Streaming ETL Pipelines With Akka Streams, Alpakka And Apache...Lightbend
Things were easier when all our data used to be offline, analyzed overnight in batches. Now our data is online, in motion, and generated constantly. For architects, developers and their businesses, this means that there is an urgent need for tools and applications that can deliver real-time (or near real-time) streaming ETL capabilities.
In this session by Konrad Malawski, author, speaker and Senior Akka Engineer at Lightbend, you will learn how to build these streaming ETL pipelines with Akka Streams, Alpakka and Apache Kafka, and why they matter to enterprises that are increasingly turning to streaming Fast Data applications.

Chapter 1 Install the port come together
The port came together allocation mission to describe how to install a port of
exchange the machine to come together in this chapter.
1.1 All say
The port come together and namely come together the physical port of a few
attribute homologies to bind to certainly arrive to become a logical passage
together.The port comes together a way can be arrive come together of a few
physical port static stateses together but ignore to connect with each other with
these physical ports of whether port matches the condition for come together or
not;But when the usage LACP agreement carry on come together, the come
together of port has to be connecting with each other with port of come together to
a logic passage towards carrying to negotiate to pass with this portses all after,
port would.
Exchange the machine provide of the port come together movement mode and
function of support following:
Support a come together of static state a control
Install a physical port in order to bind to the back of a logic port, don't
concern these physical ports whether can bind to a logic port, compulsorily
think that these ports can bind to a logic port.
Support the LACP dynamic state negotiate of come together a control
Install a physical port in order to bind to the back of a logic port, the physical
port which passes LACP agreement a consultation just can bind to a logic
port and other ports will not bind the logic's port.
Support the discharge balance that the port come together
After port come together, the data discharge which comes together a port
assign each one is come together of physical port up.

1.3 The port comes together allocation mission
1.3.1 The allocation useds for come together of logic passage
Come together a physical port to bind to certainly arrive together before, should
establish a logic port first, used for control these to bind to certainly arrive the
physical port become of passage.
The order of the underneath of the usage installs logic passage:
command purpose
interface port-aggregator id allocation useds for come together of logic
passage
1.3.2 The physical port come together
Come together many physical ports as a logic passage, can adopt a static state to
come together, can also use LACP agreement to carry on a consultation.
If adopt the static state come together and then want ~only that physical port
linkUp, and come together a port in accordance with the VALN attribute of
physical port, that port will be come together logic passage, in spite of current
whether port matches the condition that the port come together or not, also in
spite of connect with each other with that physical port of whether port matches
the condition for come together or not.
Use LACP agreement, the come together of port then has to be connecting with
each other with port of is just carry on come together towards carrying to
negotiate to pass with this portses all after, port.The initial condition that the port
can be come together is a port have to LinkUp, and what the port's consultation
come out be a works mode;In the process of come together in, all Speeds of
physical member's ports have to keep consistently, namely, if have already had a
physical port to come together success, at this time, the second Speed of physical
port have to with have already come together the Speed homology of successful
physical port;Same all physical ports have to also keep consistent with coming
together the VALN attribute of port.
The LACP provides 2 kinds to come together a way, 1 kind is an Active, another is
a Passive method, exchange machine to actively start to come together
consultation process under the Active method, but the Passive method then
passively accepts to come together consultation process, while choosing LACP to
come together, if the port come together of the both sideses all use a Passive
method and then coming together will not succeed, because the both endses all
will wait for starting to come together consultation process towards carry.
VALN attribute:The Trunk attribute, the port VLAN-Trunk of the PVID, port of port
of VLAN scope(vlan-allowed) scope(vlan-untagged) with Untag-VLAN.
The order of the underneath of the usage carries on come together to the physical
port:

1.3.3 Choose the discharge balanced way that the port comes together
behind
Many physical ports after coming together to arrive together for promise all ports
can share all data discharges, can choose a way of share the data discharge and
exchange machine to at most provide 6 kinds of strategies with balanced
discharges:
src-mac
Carry on share according to the source MAC address, then have a same
MAC address the report text of the attribute will pass on a physical port.
dst-mac
Carry on share according to the purpose MAC address, then have a same
MAC address the report text of the attribute will pass on a physical port.
both-mac
Carry on share according to the source and the purpose MAC address,
then have a same MAC address the report text of the attribute will pass on
a physical port.
src-ip
Carry on share according to the source IP address, then have a same IP
address the report text of the attribute will pass on a physical port.
dst-ip
Carry on share according to the purpose IP address, then have a same IP
address the report text of the attribute will pass on a physical port.
both-ip
Carry on share according to the source and the purpose IP address, then
have a same IP address the report text of the attribute will pass on a
physical port.
The order of the underneath of the usage can install the discharge balanced way:
Command purpose
aggregator-group load-balance Configurate flow average mode
Notice:The commutation machine of the balanced way choice(or support an
among those kinds) of the nonsupport discharge doesn't provide that
order.Provide the commutation machine of that order the balanced strategy
that can choose its support also.The dissimilarity commutation machine
