Static route on router
Hi all,
This may be the basic question of Routing but I am a sort of new to networking so I am asking.
Do I need to put route for my router’s LAN port ip to WAN (serial) port ip Or the router itself can communicate between its ports without routes.
lan (172.26.40.5) ——- Wan (202.159.228.70)
Thanks,
Dexter
Good Learning Material on Networking for Beginners?
What could be the best source for beginners to learn about the topic of this thread? Both text and videos are good, e.g. something like the tutorial titled “Learn Computer Networking” on Udemy but aimed at total beginners with no prior knowledge of the subject. NB! Please feel free to ignore the text below if you’re short on time.
[rant & stream of consciousness]
I bet some knowledge about the subject could really come in handy. For example, I have often felt helpless and clueless once I have lost my Internet connection, and I have seldom known where to look for the reasons. Recently, I have learned some basics as I bought a NAS that I had to configure. I have also done some port forwarding and I can disable bridged mode, start NAT-routing and so on. However, that’s not much to say the least, and there’s so much more to learn. Besides, I cannot really explain the things that I know by using technical terms, e.g. the real difference between bridging and NAT-routing. For someone like me, it’s just basically being directly connected to WAN vs. being securely connected to WAN as NAT is a sort of firewall (but correct me if I’m wrong). The problem is that even though I could read about these things on Wikipedia, the explanations tend to be so technical that they go over my head. In other words, they often require some prior knowledge of the subject. It’s like trying to figure out what thermodynamic entropy is all about by reading about the subject on Wikipedia without any prior knowledge — it makes no sense. Similarly, what is relevant for the masses when it comes to different subjects might be difficult to explain in a purely objective, “scientific” way. Thus, some popularization and simplifications for beginners can be quite in order… And the same theory might hold good when it comes to technical subjects such as networking — the detailed explanations should come when the time is right. Perhaps this could even be tested by giving an information-laden, detailed and technical article on some subject to one person with no prior knowledge of the subject and giving a shorter article where the subject is explained in layman’s terms to another person (with no prior knowledge of the subject either). I would not be particularly surprised to find out that the latter person ends up with a better (albeit fairly rudimentary) understanding of the subject.
To learn about some subject, you need to know what to look for… And as we know, the Internet is a good place for finding information on just about anything provided that you know what you are looking for. Other than that, it can be like a massive library. You cannot expect Mr. Joe Six-pack to become a physicist by sending him to the Oxford physics library and telling him to see what he could find there. The library, just like the Internet, is simply too massive …read more
SDNs aren't just for data center networks
SDNs aren’t just for data center networks, despite the best-use-case-scenario arguments for network virtualization and flow management pervading the industry.
SDNs can automate and manage WAN operations as well. Google is using OpenFlow to interconnect data center over a WAN.
And startup Glue Networks is targeting Cisco‘s installed base of WAN routers as a sweet spot for its SDN WAN offerings.

Gartner Positions Sprint as a Challenger in Magic Quadrant for Global Network Service Providers
OVERLAND PARK, Kan.–(BUSINESS WIRE)– Sprint (NYS: S) has advanced to a Challenger position within the most recent Gartner Magic Quadrant for Global Network Service Providers. Since the previously published Magic Quadrant report, Sprint has grown its global MPLS, Ethernet and SIP Trunking coverage for business and wholesale customers.
“Our sharp focus and investment on domestic and global MPLS footprint expansion and growing product portfolio has delighted both business and wholesale customers, and this, we believe, led to Gartner advancing Sprint from a Niche Player in last year’s report to a Challenger position in this year’s,” said Mike Fitz, vice president – wireline and solutions engineering, Sprint. “The Challenger position aligns with our mission to combine our unique insights into customer needs with a robust portfolio of managed network solutions to help companies leverage their network as a strategic differentiator. And with the increasing adoption of cloud services, the network is the most important investment a company can make to accelerate transformation and the speed of business.”
This magic quadrant report1 assesses suppliers that can deliver fixed enterprise networking services worldwide, including:
- WAN services, predominantly managed, including Multiprotocol Label Switching (MPLS) and IPsec VPNs, and Ethernet services
- Voice services, including switched and dedicated voice and SIP trunks
- Dedicated Internet services, including managed VPN offers
With its forward-thinking design approach and innovation in IP and wireless technologies, Sprint is uniquely positioned to unleash the full potential of business-critical applications and workforces through a single account team who understands converged, cloud and mobility solutions.
Also according to the report, “The number of organizations requiring global networking services continues to grow, due to globalization and cloud services, which are often hosted in different markets from the point of consumption. Organizations’ appetite for more bandwidth shows no signs of diminishing, with video and big data, coupled with IT centralization, as the primary drivers. Reliability and performance control are growing in importance as business processes become ever more IT-dependent; in addition, IT architectures (such as thin client computing) place ever greater reliance on the network.”

Can New Leadership Unlock Riverbed's Value?
By Richard Saintvilus, The Motley Fool
Filed under: Investing
Shares of Riverbed Technology are down 31% so far this year. Not only did disappointing fourth-quarter results immediately send the stock plummeting 22%, investors have now grown concerned about the company’s management — specifically, its ability to effectively synergize the company’s $1 billion deal of OPNET.
While Riverbed has done a decent job making the best out of a tough fiscal environment, the company has not been able to reverse the slowing growth in its wide area network — or WAN — optimization business. However, despite the recent slowdown, the company still boasts a solid 52% market share, surpassing rivals like Cisco . Nevertheless, investors wanted signs that the company was committed to growth, and last week they got it. But will it matter?
Good addition, but in the wrong area
Last Wednesday, the company announced that Robert Whiteley was joining Riverbed as vice president of product solutions marketing. Whiteley arrives after having spent 10 years at Forrester Research as an industry analyst. Riverbed wants to utilize Whiteley’s industry experience since he’s been involved in so many customer meetings.
As I’ve said recently, Riverbed has done a decent job meeting the needs of its customers. Plus, the company has not been doing poorly in terms of overall growth. The problem, however, has been with execution and internal operations. And regardless of what the share price may reflect, Riverbed still posted revenue growth of 17% year over year and 9% sequentially.
Likewise, product revenue was solid, up 12% year over year, while advancing 9% from Q3. So, this tells me that management is already delivering well to the customer. However, profitability is the problem. All of that growth has not materially impacted the bottom line. Profits tumbled close to 80%. I understand that the deal for OPNET had a lot to do with this. However, there continue to be operational issues that Whiteley will not be able to address.
For instance, operating margin arrived 2% lower at 27% — missing Street estimates. Plus the company only posted 8% growth in operating income. This is despite advancing gross margin by almost 1% year over year. These (among others) are the reasons why the stock is getting hammered. The company has also posted declining EPS while also hemorrhaging cash flow, which recently dropped 12.44%. So while Riverbed deserves credit for identifying an industry talent like Whiteley, the company has failed to addressed the proper areas of its operation.
Last shot at growth?
If you’re still holding shares of Riverbed, you’re still betting that the management can put this company back on track. You’re also wagering that the company will synergize OPNET to the extent that Riverbed can start posting market-beating performances. While it’s certainly impressive that OPNET‘s application management business is growing at a rate of 30%, I just don’t believe that Cisco and F5 Networks are going to make it easy.
F5 has been making moves of its own to solidify its market position by picking off LineRate Systems, …read more

PMC Disrupts 100G Economics with Industry’s First OTN Processor Enabling Virtualization of Optical Network Bandwidth for Big Data
DIGI 120G Accelerates Deployment of Efficient and Dynamic OTN Networks
SUNNYVALE, Calif.–(BUSINESS WIRE)– PMC® (NAS: PMCS) , the semiconductor innovator transforming networks that connect, move and store big data, announced today the introduction of PM5440 DIGI 120G, the industry’s only single-chip OTN processor supporting 10G, 40G and 100G speeds for OTN transport, aggregation and switched deployments. DIGI 120G allows for the efficient sharing and dynamic assignment of network resources, enabling OTN networks to effectively virtualize optical network bandwidth to meet the elastic traffic demands of Big Data. This unprecedented level of silicon integration facilitates the most cost effective designs, engineering efficiency, and lowest power approach to OTN system solutions.
Optical transport networks play a critical role in providing the interconnect infrastructure required to efficiently and reliably deliver cloud-based services. Continued growth in mobile data traffic and the projected 3X growth in datacenter driven WAN traffic1 are the catalysts behind industry’s need for 100G connectivity to aggregate the increasing deployment of 10G ports from the metro edge. To unlock the full value of 100G networks, service providers are architecting their transport infrastructure to enable dynamic bandwidth allocation with granularity from 100Gbps down to 1Gbps, without interruption to network traffic, in order to ‘virtualize’ the optical network bandwidth.
OTN allows for flexible aggregation and switching from 1G to 100G
With today’s networks dominated by 1G & 10G services, traditional point-to-point OTN transponders do not efficiently map these service rates to 100G due to a lack of OTN multiplexing granularity to 1Gbps. PMC‘s new DIGI 120G supports OTN Transport, OTN aggregation and OTN switching. Multiservice OTN muxponders and OTN switching cards using DIGI 120G will enable efficient aggregation and grooming of lower speed services into 100G.
As the industry’s first OTN processor to support on-demand re-sizing of ODUflex from 1G to 100G, as well as 10G, 40G and 100G speeds, DIGI 120G allows OEMs to deliver a full suite of multiservice OTN switched cards for Packet Optical Transport Platforms (P-OTP) and muxponders for ROADMs. Numerous configurations are supported, including 12 ports at 10Gbps, 3 ports at 40Gbps or 1 port at 100Gbps.
