WRR [Weighted Round Robin] assigns weights (queuing priority values such as 1, 2, 3) to each queue connection (bandwidth) not necessarily the protocol. The data traffic in each queue is processed (serviced) in proportion (relation) to its weight in a round-robin fashion such as 1-2-3, 3-2-1, etc.). WRR [...]

While all approaches to antenna design are beyond the scope of this tutorial, MEMS [Micro Electro-Mechanical Systems]/Switch actuator which also are used for optical switches (SEE TECHtionary MEMS) are being developed for patch antenna reconfiguration.
A key feature is the capability of multi-band (multi-frequency) operation without greatly increasing [...]

The SAML [Security Assertion Markup Language] assertions are bound into the SOAP [Simple Open Access Protocol] document’s header to secure the body of the message. The token is digitally signed using XML Signature and authenticated using one of several techniques, including an X.509 certificate or Kerberos ticket. [...]

Before discussing 6to4 Anycast relay, here’s a quick review of IP Version 4 and IP Version 6.
IPv4-to-IPv6, or Internet Protocol Version 4 to Version 6 (also known as 6to4) Relay Router Anycast routers advertise anycast address prefix into IPv4 network where IPv4 packets are routed to nearest 6to4 relay [...]

Phantom routers can exist throughout a network. The MAC [Media Access Control] address and the IP [Internet Protocol] addresses are passed among routers.
This creates a virtual router called a Phantom router. It works like this:

One router is designated as the Active router and the other [...]

Cellular-mobile, delivery, and automobile whip/rod/vertical antennas use the body/case of the object to create a virtual earth/ground to form a 1/2 wavelength antenna. That is, this type of antenna uses a 1/4 wavelength for transmission and reception and the other 1/4 for ground.

SAML does not directly provide message integrity or confidentiality; it relies on XML [eXtensible Markup Language] signature to protect integrity and on SSL-Secure Sockets Layer and TLS [Transport Layer Security] for confidentiality. According to various sources, SAML and WS-S [Web Services-Security] provide significantly different models for Web services [...]

Some background on IP Anycast:
Advantages:

IP routing will deliver packets over the shortest path to the nearest host

Client needs to be configured with only a single Anycast host address

Upon failure, routing will forward to the next nearest server with the same Anycast address

Distributed Anycast servers will effectively “load balance” traffic

Addressing

Works [...]

Layer 1 - Physical connects wires/wireless
This is the physical layer which is considered to be the “railroad track” and consists of equipment such as wiring, connectors and add-on boards that are necessary for sending data across the network. Here are some of the key elements in layer one.

Interconnects [...]

Network equalizing is the balancing of traffic allowing for time-sensitive (delay-sensitive) voice, video, and streaming data to receive an “equal share” of the available bandwidth.
Data networks are called “bursty” networks because data arrives randomly and in large amounts often causing “traffic jams.” This is not a problem for [...]

This is a comparison of various antennas and their directivity/directional transmission-reception characteristics. Directional antennas include Yagi-Uda arrays and Parabola-Parabolic-Horn antennas. Non-directional or omni-directional antennas include Whip-Rod antennas. Dipole antennas are semi-directional.
While this is a top view of antenna transmission, radio waves radiate in all three [...]

An entity can reuse a token for further requests without reauthenticating, whether within the same domain or within another domain. SAML [Security Assertions Markup Language] provides an SSO [Single Sign-On], which allows users can go from one secure site to another without signing on (login) again.

IP Anycast is defined, by Cisco, as the point-to-point flow of IP [Internet Protocol] packets between a single client and the “nearest” destination server identified by any IP Anycast address.

.NET uses XML [eXtensible Markup Language], a data formatting standard that can be integrated into OLAP [On-Line Analytical Processing] a multi-dimensional database architecture and other protocols such as SOAP [Simple Open Access Protocol] and IP [Internet Protocol]. SOAP defines how to package/format a database request (OLAP) as an [...]

Data networks are called “bursty” networks because data arrives randomly and in large amounts often causing “traffic jams.” This is not a problem for traditional networks where, if your email gets delayed by seconds or even minutes, no one knows or cares. However, certain large file email attachments, web [...]

Yagi performance gain can be increased at certain frequencies by adding equal spaced, equal length Directors, but the bandwidth is more narrow and Side Lobe levels are increased.
Large Director spacing will increase the bandwidth. By varying both the spacing and Director lengths, the gain pattern and the pattern [...]

SAML [Security Assertions Markup Language] is an XML [eXtensible Markup Language] extension designed to exchange security information in the form of Assertions about subjects. The subject is an entity (person, device, or computer) with an identity in the security domain and needs access to a protected resource.

MBGP [Multi-protocol Border Gateway Protocol] is used to carry unicast prefixes of source networks across AS [Autonomous Systems] boundaries. RP in different AS establishes peer arrangement to exchange MBPG updates called MSDP [Multicast Source Discovery Protocol] SA [Source Address] AM [Active Messages]. AM are used to know about active [...]

In some cases, distant-vector and link-state protocol can coexist in the same router, each with its own methods and procedures for handling route lists or tables as well as packet (data) processing. Since this is a dynamically changing issue, check with the router manufacturer for specific details.
