  1. 1. fam’s teleco news (11ªEd-2-2011.) 1/7 Noticias TIC Febrero 20111.- PRISA a punto de perder 37 licencias radiofónicas en ChileSe ha informado la suspensión de renovación de Concesiones Radiales del grupo aludido, quehegemoniza las frecuencias en Chile, con 77 señales bajo su administración y con el control de más dedos tercios del mercado publicitario nacional. Diversas organizaciones y medios del país, han denunciado,permanentemente, la concentración de Iberoamericana Radio Chile y el incumplimiento del principio dereciprocidad establecido en el artículo 9° de la Ley de Prensa, situación que ha sido acogida por la actualadministración de gobierno para llevar a cabo este proceso fiscalizador.De: Broadcaster News – Texto complete: Ericsson Expands GPON SolutionsEricsson has made several enhancements to its GPON solutions. Its EDA 1500 platform now has a new16-port GPON OLT board, enabling broadband services to more than 14,000 FTTH GPON subscribers in asingle EDA 1500 chassis.Ericsson is also introducing an Integrated TDM Gateway (ITG) board to the EDA 1500, enabling aconverged platform for packet and TDM services across fixed enterprise and mobile applications. The ITGterminates and aggregates E1 services across multiple GPON ports at the OLT for STM-1 connectivity toexisting TDM networks.Also, Ericsson is further expanding its EDA portfolio with the T780G Optical Network Unit (ONU). ThisGPON-fed modular ONU provides flexibility for operators delivering ADSL2+, VDSL2, POTS, E1 andEthernet services to both business and residential users. The T780G enables operators to support denseareas with different service requirements without rewiring buildings. The ONU is part of Ericsson’s T-series of optical terminals, which provides maximum flexibility to deploy deep fiber access networks.De: CT Reports3.- CHILE AVANZA PARA REDUCIR COSTOS DE BANDA ANCHAYa se ha logrado conversar con Google y YouTube para convencerlos de acercar sus servidores aLatinoamérica, y atraer a inversionistas para instalar nuevos cables. A paso firme avanza la Subsecretaríade Telecomunicaciones (Subtel) en su meta de reducir los costos de la banda ancha, no sólo en Chile,sino que también en toda Latinoamérica, con resultados en cada uno de los puntos que se definieroncomo esenciales para lograr el objetivo de la iniciativa, que además integran Argentina, Brasil, Bolivia,Perú, Paraguay, Uruguay, Colombia, Ecuador y, próximamente, Costa Rica.De: Broadcaster News : doc completo en: SAN performance best practices: More ways to avoid bottlenecksGeorge Crump, Contributor 02.15.2011 What youll learn in this tip: There are several ways you can fine-tune and improve your storage-areanetwork (SAN). This tip covers topics such as using ISLs and understanding HBA queue depth to help youavoid storage bottlenecks.In this tip, we take a closer look at how SAN performance and SAN efficiency improve with transparency,testing and a better understanding of the impact your data storage has on the rest of your system. Checkout our earlier tip on how to improve your storage networks to find out how storage performance issuesare often linked to data storage networks with outdated information or that dont undergo regulartesting.Tip 1. Understand how youre using ISLsInter-switch links (ISLs) are critical areas for tuning and, as a SAN grows, they become increasinglyimportant to performance. The art of fine-tuning an ISL is often an area where different vendors willhave conflicting opinions on what a good rule of thumb is for switch fan-in configurations and the number
  2. 2. fam’s teleco news (11ªEd-2-2011.) 2/7of hops between switches. The reality is that the latency between switch connections compared to thelatency of mechanical hard drives is dramatically lower, even negligible; however, in high fan-in situationsor where there are a lot of hops (servers crossing multiple switches to access data), ISLs play animportant role. The top concern is to ensure that ISLs are configured at the correct bandwidth between the switches,which seems to be a surprisingly common mistake. Beyond that, its important to measure the traffic flowbetween hosts and switches, and the ISL traffic between the switches themselves. Switch reporting toolswill provide much of this information but, a visual tool that measures switch intercommunication may bepreferable.Based on the traffic measurements, a determination can be made to rebalance traffic flow by adjustingwhich primary switch the server connects with, which will involve physical rewiring and potential serverdowntime. Another option is to add ISLs, which increases bandwidth but consumes ports and, to someextent, further adds to the complexity of the storage architecture.Tip 2. Use NPIV for virtual machinesServer virtualization has changed just about everything when configuring SANs and one of the biggestchallenges is to identify which virtual machines are demanding the most from the infrastructure. Beforeserver virtualization, a single server had a single application and communicated to the SAN through asingle host bus adapter (HBA); now virtual hosts may have many servers trying to communicate with thestorage infrastructure all through the same HBA. Its critical to be able to identify the virtual machinesthat need storage I/O performance the most so that they can be balanced across the hosts, instead ofconsuming all the resources of a single host. N_Port ID Virtualization (NPIV) is a feature supported bysome HBAs that lets you assign each individual virtual machine a virtual World Wide Name (WWN) thatwill stay associated with it, even through virtual machine migrations from host to host. With NPIV, youcan use your switches statistics to identify the most active virtual machines from the point of view ofstorage and allocate them appropriately across the hosts in the environment.Tip 3. Know thy HBA queue depthHBA queue depth is the number of pending storage I/Os that are sent to the data storage infrastructure.When installing an HBA, most storage administrators simply use the default settings for the card, but thedefault HBA queue depth setting is typically too high. This can cause storage ports to become congested,leading to application performance issues. If queue depth is set too low, the ports and the SANinfrastructure itself arent used efficiently. When a storage system isnt loaded with enough pending I/Os,it doesnt get the opportunity to use its cache; if essentially everything expires out of cache before it canbe accessed, the majority of accesses will then be coming from disk. Most HBAs set the default queuedepth between 32 to 256, but the optimal range is actually closer to 2 to 8. Most initiators can report onthe number of pending requests in their queues at any given time, which allows you to strike a balancebetween too much and not enough queue depth.Tip 4. Multipath verificationMultipath verification involves ensuring that I/O traffic has been distributed across redundant paths. Inmany environments, our experts said they found multipathing isnt working at all or that the load isntbalanced across the available paths. For example, if you have one path carrying 80% of its capacity andthe other path only 3%, it can affect availability if an HBA or its connection fails, or it can impactapplication performance. The goal should be to ensure that traffic is balanced fairly evenly across allavailable HBA ports and ISLs.You can use switch reports for multipath verification. To do this, run a report with the port WWNs, theport name and the MBps sorted by the port name combined with a filter for an attached device typeequal to "server." This is a quick way to identify which links have balanced multipaths, which ones arecurrently acting as active/passive and which ones dont have an active redundant HBA.Tip 5. Improve replication and backup performanceWhile some environments have critical concerns over the performance of a database application, almostall of them need to decrease the amount of time it takes to perform backups or replication functions.Both of these processes are challenged by rapidly growing data sets that need to be replicated acrossrelatively narrow bandwidth connections and ever-shrinking backup windows. Theyre also the most likely
  3. 3. fam’s teleco news (11ªEd-2-2011.) 3/7processes to put a continuous load across multiple segments within the SAN infrastructure. The backupserver is the most likely candidate to receive data that has to hop across switches or zones to get to it.All of the above tips apply doubly to backup performance. Also consider adding extra HBAs to the backupserver and have ports routed to specific switches within the environment to minimize ISL traffic.BIO: George Crump is president and founder of Storage Switzerland, an IT analyst firm focused on thestorage and virtualization segments.DE: .

So says ITU Secretary-General Dr Hamadoun Touré, adding that accelerated fibreroll-out and greater spectrum availability will be imperative if network bottlenecks are to be avoided. Smartphone users already consume on average five times more data capacity than users of ordinarymobile phones[1]. With the number of smartphones set to rise from today’s global estimate of 500 millionhandsets in use, to almost two billion by 2015, operators are already having to employ multi-prongedstrategies to keep up with demand – and not all are succeeding[2]. “Mobile operators have been investing billions to upgrade and improve the capacity and performanceof their networks, but in some high-usage cities, such as San Francisco, New York and London, we arestill seeing users frustrated by chronic problems of network unavailability. “Robust National Broadband Plans that promote extra spectrum and the faster roll-out of the fibernetworks which are essential to mobile backhaul are vital to support the growing number of data-intensive applications,” says Dr Touré. ITU analysis shows 98 countries have National Broadband Plans inplace, with this number set to increase over the next year.De: ITU Newsroom. Press Release.
